FIELD

[0002] The present subject matter relates to systems and methods for providing automated engagement with guests of a facility using wireless sensing technologies, and more particularly, but not exclusively, to wireless devices and methods for making and using the same.

BACKGROUND

[0003] Guests of hotels and resorts, cruise ships, as well as other retail and commercial establishments, have come to expect a high level of service and engagement from their hosts. The service can include being provided with ready access to private and/or restricted areas without having to present a badge or other form of identification, to swipe or tap an access card, or to otherwise proactively authenticate themselves. The engagement can include being personally recognized by the hosts and provided with services and recommendations on that basis, without requiring the guests to identify themselves and remind the host of their preferences or pre-existing bookings.

[0004] A novel guest engagement system that relies on recent improvements in low power wireless communication technologies and distributed sensor networks to provide novel services to those guests without requiring guests to proactively identify and/or authenticate themselves has been developed, for example, as described in commonly owned U.S. Patent No. 10,045,184, entitled “Wireless Guest Engagement System,” filed on March 15, 2017, which disclosure is hereby incorporated by reference in its entirety and for all purposes. The guest engagement system thereby enables hosts to seamlessly engage with the guests throughout their facilities and provide recommendations to the guests based on the guest’s previous experiences. [0005] However, the guests of hotels and resorts are not the only beneficiaries of the novel guest engagement system. For example, the crew, employees, and hosts of the hotels and resorts can also leverage the low power wireless communication technologies for security, guest engagement, and other purposes.

[0006] Although conventional wireless devices disclose various techniques for estimating or determining a location of the device, these techniques may not always work to track the location of persons and/or assets when they are out of the sensor network. This is particularly difficult, for example, on a cruise ship where resources may be limited. Therefore, these conventional techniques cannot accurately detail guest movements, for example, leading up to infection or exposure for purposes of contact tracing.

[0007] In view of the foregoing, a need exists for systems and methods for improved guest devices and accessories for optimizing performance in low power wireless networks to overcome the aforementioned obstacles and deficiencies of conventional guest devices.

DETAILED DESCRIPTION

[00130] In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and/or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings.

[00131] The various techniques and equipment systems disclosed herein enable automated engagement with users or guests of a facility using wireless sensing technologies.

[00132] The guest engagement system relies on wireless sensing technologies to securely identify guests based on medallions worn or carried by the guests, and to automatically provide services to the guests based on the secure identification. The system additionally provides enhanced engagement with guests by maintaining a database of guest locations and experiences, and enabling services to be provided to the guest seamlessly regardless of the guests’ locations. [00133] FIG. 1A provides a general block diagram showing components of a guest engagement system 10. The guest engagement system 10 of FIG. 1A may be provided in a facility such as a ship (e.g., cruise ship), hotel, restaurant, resort, convention center, medical center or other treatment facility, retail or other commercial establishment, entertainment venue (e.g., conceit hall, movie theater, arena, or stadium, amusement park or casino), transportation center (e.g., airport, marine port or terminal, train or bus station, multi-modal transport center), or other facility or combination of such facilities. In one example, the facility may be a cruise ship hosting large numbers of guests, or a cruise ship line including multiple cruise ships, associated shore facilities (e.g., port facilities), and partnering facilities (e.g., facilities of partners providing shore activities for cruise guests). In another example, the facility may be a resort including one or more hotels, restaurants, theaters, amusement parks, and other associated facilities distributed across one or more geographic locations. In a further example, the facility may be a set of facilities associated with a particular event, such as a convention or tradeshow, that includes locations of multiple partnering establishments (e.g., hotels, restaurants, museums, arenas, malls or other retail locations). Users of the guest engagement system are referenced generally herein as guests 12. In the example of a cruise ship, the guests 12 include cruise passengers and can more generally include stewards, staff, and other users of guest devices 11. In other examples, guests 12 can include any person interacting with the guest engagement system 10 including users of guest devices 11. Guests 12 may thus reference patients, nurses, doctors, and visitors, among other users, in the illustrative context of a medical or treatment facility; convention goers and/or exhibitors in the illustrative context of a convention facility; shoppers, staff members, travelers, sales personnel, and others in illustrative contexts of various types of commercial establishments.

[00134] The guest engagement system 10 is configured to communicate wirelessly with guest devices 11, such as medallions worn or carried by guests 12, which each uniquely identify an associated guest and are configured for secure communication with the guest engagement system 10. In the examples detailed herein, the guest devices 11 take the form of medallions and will genetically be referenced as medallions in this disclosure. However, the devices/medallions 11 can take other formats, and the term medallion thus is not intended to limit the scope of guest devices 11 that may be used as part of the system 10. The guest devices/medallions 11 are preferably light and compact so as to be readily worn or carried by users. The guest devices/medallions 11 are configured to communicate using at least one wireless communication technology/protocol and, preferably, are configured to communicate using two or more distinct wireless communication technologies/protocols. For example, a medallion 11 can be configured to communicate according to both near field communication (NFC) standards and Bluetooth low energy (BLE) standards, though the medallion 11 may generally operate using only one of the standards at any given time in order to reduce energy expenditure.

[00135] The guest engagement system 10 includes a sensor network 13 of sensors 15 mounted throughout the facility and configured to communicate wirelessly with guests’ medallions 11. A sensor 15 of the network 13 may be used for sensing a guest’s location (or proximity to the sensor 15), for example by detecting beacon signals or other signals emitted by the medallion 11. The sensor 15 can also engage in two-way communication with the medallion 11 to transmit information to and receive information from the medallion 11. A sensor 15 may also be located in or otherwise associated with a particular interface device 17 or interface function of the system, such as a sensor that is associated with a door lock 17a, an automatic door or turnstile, a vending terminal 17b, a cash register, a slot machine, an interactive display 17c or portal 17d, or the like. In some situations, the sensor 15 is mounted within the interface device 17, while in other situations, a sensor 15 associated with an interface device 17 is mounted in the vicinity of the interface device. For example, a spotlight sensor can be placed above a location at which a user interacting with the interface device 17 would be located (e.g., above a location directly in front of, and around 1 foot away from, the interface device 17), so as to only sense beacon signals emitted by medallions of users located directly in front of and close to the interface device 17. When associated with a particular interface device 17 or interface function, the sensor 15 may engage in two-way communication with the medallion 11 and provide a secure communication channel between the device and medallion, for example to provide automatic unlocking of the door lock based on secure authentication of a particular guest’s medallion. [00136] The guest engagement system 10 can further make use of end devices such as BLE-enabled mobile devices, tablet computers, or interactive displays to provide services to guests through sensing of (and communication with) medallions 11. The services provided using end devices can be provided in addition to the aforementioned services provided using the sensors 15 of the sensor network 13 and of interface devices 17 to provide services. As described in further detail below (see, e.g., the discussion of FIG. 9), the services provided through the end devices can include location services (including location-sensing of medallions based on the end devices sensing medallions’ beacon signals, and reporting of sensed medallions and locations to a system server 21), and causing medallions to switch into or out of a various operating modes (e.g., sleep, beacon, and bi-directional modes), among other services. [00137] The guest engagement system 10 also includes one or more servers 21 communicatively connected to the network 13 of sensors, to the interface devices 17, and wirelessly to the medallions 11 via the various sensors 15 provided throughout the guest engagement system 10 and the associated facility. One or more communications network(s) 19 provide communication capabilities between the various elements of the system 10. In one example, the guest engagement system 10 includes at least one authentication server used to authenticate guests’ medallions and provide encryption and decryption services. The system can further include one or more servers storing databases of guest information (e.g., guest reservations, guest preferences, status of activities that the guest has participated in, and so on), payment transaction servers (e.g., including guest billing information), location information (e.g., locations of sensors 15 within the facility, and locations of medallions 11 throughout the facility and elsewhere) and the like.

[00138] Detailed descriptions of various components of the guest engagement system 10 will now be provided with reference to the accompanying figures. The descriptions are focused on illustrative embodiments of components of the system, and do not limit the scope of attributes and functions of the components and system.

[00139] Two different structures of sensors 15 can be used in the system. In one example, each individual sensor 15 in the guest engagement system 10 includes a processor and memory that control, at least in part, operation of the sensor 15. In such an example, each sensor may additionally include a network transceiver including a communication port for communicatively connecting the sensor 15 to the communication network 19. The network transceiver may be an Ethernet, Wifi, or other appropriate transceiver.

[00140] Alternatively or additionally, the guest engagement system 10 may include sensor network peripherals 14 distributed throughout the facility and operative to have sensors 15 directly connected thereto. In such an example, FIG. IB provides a general block diagram showing a more detailed view of the sensor network 13 of the guest engagement system 10 showing sensor network peripherals 14 that are used to connect sensors 15 to the communication network 19. In particular, as shown in the figure, sensors 15 of the sensor network 13 are each directly connected to respective sensor network peripherals 14, and each receive power from and operate under the control of the corresponding sensor network peripheral 14. In turn, the sensor network peripherals 14 are connected to the communication network 19 and communicate with the servers 21 through the network 19.

[00141] Each sensor network peripheral generally includes a network transceiver for communication with the communication network 19, such as an Ethernet, Wifi, or other appropriate network transceiver. Each sensor network peripheral 14 further includes at least one port for connecting at least one associated sensor 15. For example, the sensor network peripheral

14 typically includes one or more communication buses through which multiple sensors 15 or other devices can be connected. For instance, a sensor network peripheral 14 may include two buses each operative to connect up to sixteen sensors 15 in one example. Through these connections, the sensor network peripherals 14 serve to relay sensing information captured by the sensors 15 to the communication network 19 and servers 21, and to relay control or communications from the communication network 19 and servers 21 back to the sensors 15. The sensor network peripherals 14 may further relay data or other communications received from medallions 11 by the sensors 15 to the communication network 19 and servers 21, and to relay control or communications from the communication network 19 and servers 21 back to the medallions 11 via the sensors 15.

[00142] Each sensor network peripherals 14 includes a processor and memory, and is operative to control operation of the sensor(s) 15 connected thereto. In particular, the use of the sensor network peripheral 14 can enable the guest engagement system 10 to function with sensors

15 having minimal (or no) on-board processing power and memory, and sensors 15 requiring minimal configuration during initial system installation. In particular, through the use of the sensor network peripherals 14, the individual sensors 15 do not need to store individual network identifiers (e.g., unique network addresses) for use by the sensors 15 to identify themselves on the communication network 19 and to identify data transmitted by each respective sensor 15 on the network 19 as having originated in the respective sensor 15. Instead, the sensor network peripherals 14 are configured to package data received from sensors 15 connected thereto for communication across the network 19, and in particular are configured to associate with data received from each respective sensor 15 an identifier for the respective sensor 15. The sensor network peripherals 14 are further configured to packetize the data from the sensors 15 for communication across the network 19. Additionally, the individual sensors 15 do not need to be operative to communicate on the network 19, and each respective sensor 15 does not need to have processing power sufficient to identify and process packets destined for the respective sensor from among packets communicated across the network 19. Instead, the sensor network peripherals 14 are configured to process data communicated across the network 19 to identify packets destined for the respective sensor network peripheral 14 and/or for sensors 15 connected thereto, to process instructions included in the packets, and to control the appropriate sensor(s) 15 connected thereto according to the processed instructions.

[00143] As described above, the use of sensor network peripherals 14 thereby enables the wireless guest engagement system 10 to operate using low cost sensors 15 that do not include network communication circuitry and include no or minimal processing power and memory. Additionally, the use of sensor network peripherals 14 enables the wireless guest engagement system 10 to be configured for and begin operation without having to assign individual network identifiers to each sensor 15, and/or without having to configure the servers 21 with information on each individual sensor 15 in the system. Instead, the wireless guest engagement system 10 can be configured for operation by connecting multitudes of sensors 15 directly to nearby sensor network peripherals 14 located throughout the facility, and configuring the sensor network peripherals 14 for communication through the communication network 19 with the servers 21. [00144] While the foregoing description has focused on sensor network peripherals 14 being directly connected to sensors 15 configured to sense the presence of and/or communicate with medallions 11, the sensor network 13 and the sensor network peripherals 14 can more generally support other types of sensors or devices (reference generally by numeral 16 in FIG. IB). Specifically, the sensor network 13 and the sensor network peripherals 14 can be used to control operation of and relay sensing data from the other sensors or devices 16 through the communication network 19. The sensors or devices 16 may include sensors such as smoke or CO (carbon monoxide) sensors, infrared or occupancy sensors, photodiodes or light sensors, temperature and/or humidity sensors, and the like. The other sensors or devices 16 can also include devices such as speakers and/or microphones (e.g., parts of a public address (PA) system), actuators or controllers (e.g., for opening or closing vents or window shades), switches or relays (e.g., for turning on/off lights, heating and ventilation, power), cameras (e.g., as part of a security system), and the like. The sensor network peripherals 14 can further be configured to support sensors mounted in (or associated with) vending terminals 17b, interactive displays 17c, and other interface devices 17 described throughout this document. [00145] The functionality provided by the sensor network peripherals 14 can also be incorporated into other components of the wireless guest engagement system 10. Notably, the functionality of the sensor network peripherals 14 can be incorporated into components that include a processor, memory, and a network transceiver for communication across the communication network 19. For example, as shown in FIG. IB, an access panel 705 provided in association with a door lock 17a may be configured for use as a sensor network peripheral 14. Note that the access panel 705 is described in further detail below in relation to FIGS. 7A-7I. In the example of FIG. IB, the access panel 705 can include at least one port and/or bus for connecting one or multiple sensors 15 thereto, and the access panel 705 may be configured to support operation of the sensors 15 as described above in relation to the sensor network peripherals 14.

[00146] As detailed above, a guest device 11 can take the form of a medallion 11, such as the illustrative medallion 11 shown in FIG. 2A. As shown, the medallion 11 takes the form of a token having an outer diameter of approximately 1.25 inches (range of 0.75 to 2.5 inches), a thickness of approximately 3/8 inch (range of 1/8 to 5/8 inch), and a weight of approximately 1.8 ounces (range of 1.2-2.4 ounces).

[00147] The medallion 11 is configured to be insertable into different accessories worn by guests 12. The accessories enable the medallions 11 to be securely attached to the guests 12 so as to ensure that guests do not inadvertently lose or misplace their medallions. FIG. 2B shows an illustrative accessory 201 that takes the form of a wrist-band or bracelet. Other types of accessories, including lanyards, pendants, keychains, necklaces, belt buckles, bathing suites (e.g., bikini rings), body piercings, and the like, some of which are shown in FIGS. 4A-4F, can also be used. The medallion 11 is configured to be inserted into a cavity of the wrist-band accessory 201 that is shaped and sized to receive the medallion 11. As shown, the medallion 11 is inserted via a rear of the wrist-band accessory 201, i.e., via a side of the accessory 201 that is designed to face the user, such as the inside surface of the wrist-band that is designed to contact a wrist of a user when the wrist-band is worn. The medallion 11 is inserted via a rear of the wrist-band accessory 201 so as to ensure that the medallion 11 cannot inadvertently slip out of the accessory 201 when the accessory 201 is worn by the user. In particular, as shown in FIG. 2C, the cavity of the accessory 201 configured to receive the medallion can be tapered and thus have an angled or chamfered edge ensuring that the medallion 11 can be inserted into cavity of the accessory 201 but cannot pass through the cavity and exit the accessory 201 through a front surface thereof. In the example of FIG. 2C, the edge is angled at approximately 3 degrees relative to a right- angled edge (corresponding to an angle of 87 degrees relative to the front or back surface). In detail, the cavity in the example of FIG. 2C may not have a cylindrical shape but may instead have a tapered shape, e.g. a frustum shape of a slice of a cone having a circular base and edges angled relative to the circular base at a predetermined angle (e.g., 3 degrees (+/- 1 degree) relative to a right-angled edge, corresponding to an angle of 87 degrees (range of 86-88 degrees) relative to the front or back surface). The angle is such that the rear/lower opening of the cavity is larger than the front/upper opening, to thereby prevent the medallion 11 from passing through the cavity.

[00148] Similarly, the medallion 11 can tapered shape having an angled edge along is outer peripheral surface, and the edge may be angled with a predetermined angle equal to that of the cavity (e.g., 3 degrees (+/- 1 degree) relative to a right-angled edge, corresponding to an angle of 87 degrees (range of 86-88 degrees) relative to the front or back surface), as also shown in FIG. 2C. The angled edge of the medallion is such that the medallion has a smaller dimension (e.g., smaller diameter) on the front/upper surface 11a of the medallion 11 relative to the back/lower surface l ib of the medallion 11. As such, the combination of angled edges of the medallion 11 and cavity in the accessory 201 ensure that the medallion can only be placed in the accessory 201 in such a way that the front surface 1 la of the medallion 11 faces outwards while a back surface 1 lb faces rearwards. Additionally, the medallion 11 may be sized to be slightly smaller than the cavity so as to ease the fit of the medallion 11 within the cavity. For example, the medallion 11 may have an outer dimension, such as an outer diameter, that is 0.75mm (e.g., range of 0.5-1 mm) smaller than the inner dimension/diameter of the cavity to enable the medallion 11 to be inserted into the cavity even in the medallion is not perfectly aligned with the cavity and/or is tilted with respect to the cavity.

[00149] In summary, the medallion can thereby easily and securely couple to the accessory 201 by virtue of the following features. The medallion 11 has an angled edge, sloping at a predetermined angle (e.g., 3 degrees) from the “front” surface of the medallion to the “rear” surface so as to align with the oppositely formed angled edge of the accessory 201. The angled edge design allows for alignment of the medallion 11 to the accessory by inserting the medallion in the “rear” side of the accessory. Since the medallion 11 can only be inserted into or removed from the rear of the accessory 201, the forces needed to dislodge the medallion 11 from the accessory 201 are rearward and thus opposed to a body of a guest wearing the accessory 201 (and/or opposed to another surface preventing the easy dislodging of the medallion) when the medallion is in the accessory 201. As such, the medallion 11 cannot readily be dislodged or removed from the accessory 201 when the accessory is worn 201.

[00150] The foregoing description has focused on medallions 11 having circular shapes, and corresponding cavities having circular shapes. However, this disclosure is not limited to such medallions and cavities. More generally, medallions 11 and corresponding cavities in accessories may have oval or other rounded shapes or square, rectangular, or other angular shapes (e.g., triangular, pentagonal, hexagonal, etc.). In each case, the medallions 11 and corresponding cavities may have tapered shapes including angled edges sloping at a predetermined angle (e.g., 3 degrees) from the “front” surface of the medallion to the “rear” surface so as to ensure that the medallion 11 can only be inserted into or removed from the rear of the accessory 201. In such cases, the medallions 11 may have front and rear surfaces having substantially similar (or identical) shapes and different dimensions so as to confer the tapered shape to the medallions 11, and the cavities in the accessories may similarly have front and rear openings having substantially similar (or identical) shapes and different dimensions so as to confer the tapered shape to the cavities.

[00151] Additionally, the medallion 11 and accessory 201 can include magnets used to ensure that the medallion 11 is automatically positioned in a predetermined rotational orientation with the cavity of the accessory 201 (e.g., self-alignment of the medallion 11 in the accessory 201). The magnets additionally provide magnetic adhesion between the medallion 11 and accessory 201 to reduce the chances of the medallion 11 coming loose from (and/or falling out of) the accessory 201. Different numbers of magnets can be used for this purpose. For example, two, three, four, or five or more magnets can be used. The magnets may be evenly spaced around peripheries of the medallion 11 and of the cavity or, more generally, can be spaced at predetermined locations around the peripheries selected such each magnet mounted in the medallion 11 aligns with a corresponding magnet mounted in the periphery of the cavity when the medallion 11 is inserted in a desired orientation in the cavity of the accessory.

[00152] As shown in FIG. 2D, four magnets can be provided in the accessory 201 at positions aligned with four magnets provided in the medallion 11 to ensure that the medallion 11 is always orientated in the correct position in the X and Y axis. In particular, opposite polarity magnets can be provided at each location in the medallion 11 and accessory 201, as shown in FIG. 2E, so as to automatically align the medallion 11 in a particular rotational orientation relative to the accessory 201. For example, in the magnet coupling mechanism of FIG. 2E, the magnets on the top of the medallion 11 and accessory 201 (e.g., the “top” in the orientation shown in FIG. 2D) have polarities that are inverted relative to the magnets at the bottom of the medallion 11 and accessory 201 (e.g., the “bottom” in the orientation shown in FIG. 2D), so as to prevent the medallion 11 from being inserted rotationally upside down relative to the orientation shown in FIGS. 2D and 2E. This feature, along with the angled edges detailed in relation to FIGS. 2B and 2C, ensure that the medallion 11 can only be (or is preferentially) inserted into the accessory 201 in one orientation. As shown in FIG. 3 A, the medallion 11 can have a metal outer rim and a plastic body disposed within the interior of the metal outer rim. Electronics included in the medallion 11 are mounted within the plastic body. The metal outer rim is interrupted in at least one location to form an open ring, and includes a plastic or other non-conducting spacer within the resulting gap. For example, in the embodiment of FIG. 3 A, the metal outer rim is formed of two separate semi-circular metal housings that, when disposed along the outer rim of the medallion 11, are spaced part from each other by two diametrically opposed gaps. The gaps in the metal outer rim (or between metal outer rim parts) ensure that eddy currents cannot flow around the metal outer rim, and thereby ensure that eddy current flow does not significantly dampen the wireless communication capabilities of the medallions 11. Alternatively, as shown in FIG. 3E, the circular metal housing can include one or more gaps that are filled by injection molded plastic. As also shown in FIG. 3E, the circular metal housing can include indentations for placing magnets such as those described above in relation to FIGS. 2D-2E. In general, the metal outer ring is formed of a non-magnetic metal material and can be formed, for example, of burnished aluminum.

[00153] A similar gap in a metal outer rim can be included in accessories 201, as shown in FIG. 3B. In detail, in embodiments in which an accessory 201 is metallic or includes metallic components around the periphery of the cavity configured to house the medallion 11, the accessory 201 includes a gap in the metal outer rim of the cavity. The gap in the metal outer rim (or between metal outer rim parts) ensures that eddy currents cannot flow around the metal outer rim, and thereby ensures that eddy current flow does not significantly dampen the wireless communication capability of a medallion 11 housed in the accessory 201. To ensure proper function of the gaps in the metal outer rims of the medallion 11 and accessory 201, the gaps of the medallion 11 and accessory 201 should be aligned when the medallion 11 is mounted in the accessory 201. Specifically, the alignment of the gaps ensures that even if the outer metal rims of the medallion 11 and accessory 201 contact each other, the metal rims do not jointly form a closed metal loop around the electronics of the medallion 11. In order to ensure alignment of the gaps, magnets such as those described above in relation to FIGS. 2D and 2E can be used to provide a desired rotational alignment of the medallion 11 within the accessory 201. The geometry and polarity of the magnets are arranged so as to have the medallion self-orient in the accessory with the gaps in the metal outer rings aligned with each other (e.g., adjacent to each other or in contact with each other).

[00154] The gaps in the medallion 11 and in the accessory 201 have widths selected to ensure that a closed metal loop is not formed even if the medallion 11 and the accessory 201 are not in perfect alignment. Alternatively or additionally, an insulating liner 41 such as a plastic or other insulating liner shown in FIGS. 3C and 3D can be provided along an inner surface of the cavity in the accessory 201 housing the medallion 11. The insulating liner 41 can extend along an entire circumference of the cavity, or the insulating liner 41 can be located so as to contact the gap in the metal outer rim of a medallion 11 when the medallion 11 is mounted in the desired orientation in the accessory 201. The insulating liner 41 ensures that a metal rim of the accessory 201 does not form a short circuit across the gap in the metal outer rim of the medallion 11 by providing insulation between the gap in the metal outer rims of the medallion 11 and the accessory 201.

[00155] As shown in FIG. 2B, the accessory 201 can take the form of a wrist-band. However, other accessory formats can also be used. For example, FIGS. 4A-4E show various other types of accessories configured to have medallions 11 inserted therein. In this regard, FIG. 4A shows a sport band accessory including a sports band (made, e.g., of silicone), a retaining ring (made, e.g., of stainless steel and including a gap filled with a non-conducting material 31) that fits into the sports band and includes indentations for holding magnets, and a two-part clasp designed to close the band around a user’s wrist. The retaining ring includes, in its center, the cavity configured to releasably house a medallion 11. FIG. 4B shows a clip (made, e.g., of aluminum) that includes a cavity configured to releasably house a medallion 11, and further includes a gap filled with a non-conducting material 31 around the periphery of the cavity. The clip may be attached to a keychain in some examples. FIG. 4C shows a cuff (made, e.g., of nylon) that includes a retaining ring (made, e.g., of stainless steel and including a gap filled with a non-conducting material such as plastic) that fits into the cuff and includes indentations for holding magnets. The retaining ring includes, in its center, the cavity configured to releasably house a medallion 11.

[00156] FIG. 4D shows a bracelet (made, e.g., of stainless steel including a gap 32 filled with a non-conducting material 31), and a retaining ring 33 (made, e.g., of stainless steel and including a gap filled with a non-conducting material 31) that fits into the bracelet and includes indentations 34 for holding magnets. The retaining ring includes, in its center, the cavity configured to releasably house a medallion 11. FIG. 4E shows a pendant (made, e.g., of stainless steel including a gap 32 filled with a non-conducting material 31), and a retaining ring 33 (made, e.g., of stainless steel and including a gap filled with a non-conducting material 31) that fits into the pendant and includes indentations for holding magnets. The retaining ring includes, in its center, the cavity configured to releasably house a medallion 11. In some examples, the pendant is configured to attach to a decorative chain for wearing by a guest. In other examples, the pendant is configured to attach to a keychain or other item. Finally, FIG. 4F shows a mount configured to be worn using a watch-type band. The mount (made, e.g., of stainless steel including a gap filled with a non-conducting material) has a retaining ring (made, e.g., of stainless steel and including a gap filled with a non-conducting material 31) that fits into the mount and includes indentations for holding magnets.

[00157] The accessories shown in FIGS. 4A-4E are non-limiting examples of accessories in which medallions 11 can be mounted. However, other types of accessories, including lanyards, pendants, keychains, necklaces, belt buckles, bathing suites (e.g., bikini rings), body piercings, and the like, may also be used.

[00158] The foregoing description of the medallions 11 has focused on external attributes of the medallions 11, such as the medallions shown in FIG. 5 A. Specifically, FIG. 5 A shows top, bottom, and side views of an illustrative medallion 11. The following description of FIGS. 5B-5E details internal structures of various embodiments of the medallions.

[00159] As shown in FIGS. 5B, 5C, 5D, and 5E, different embodiments of medallions 11 include magnets 501, a bottom cap 503, a foam filler 505, a battery assembly 507 (e.g., a CR2025 battery), an insulation film spacer 509, a printed circuit board assembly (PCBA) 511, a BLE antenna 513 (e.g., a J-shaped BLE antenna), an NFC antenna 515 (e.g., a wound wire coil antenna), a metal housing 517 (e.g., of aluminum), and a top cap 519. The BLE antenna 513 can be soldered to an upper surface of the PCB 511, while the NFC antenna 515 may be connected to the PCB 511 by pogo pins. In the embodiment of FIG. 5E, the NFC antenna 515 is coated in silicone for durability. As shown in FIG. 5B, the magnets 501 may fit within indentations provided in the top cap 519 (or, alternatively, in the bottom cap 503) and be held in place by the indentations. Alternatively, as shown in FIG. 5E, the magnets 501 may fit within indentations provided in the silicone coating the NFC antenna 515 and may be held in place by the indentations.

[00160] In the embodiment of FIG. 5B, 5D, and 5E, the metal housing 517 is manufactured separately from the bottom and top caps 503 and 519. The metal housing 517 may be made of aluminum or other metal, while the bottom and top caps 503 and 519 may be made of plastic. In contrast, in the embodiment of FIG. 5C, the top cap 519 is integrally formed with the metal housing 517. For example, in the embodiment of FIG. 5C, the top cap 519 and metal housing 517 may be machined out of a block of material including metal and plastic materials disposed within the block such that, following machining, the top cap 519 has an open metal ring (e.g., at 517) disposed around its outer peripheral surface that is interrupted by one or more gaps that are filled with plastic or other insulating material. Additionally, following machining, the top cap 519 has a plastic (or insulating) center. For this purpose, the block of material used for machining may be a plastic-impregnated metal.

[00161] FIGS. 5F and 5G show detailed views of PCB assemblies 511 used in medallions 11, which show in detail the J-shaped BLE antenna mounted on an upper surface of the PCB. As shown in FIG. 5F, the J-shaped BLE antenna can be formed of stamp-cut steel, include machine- bent tabs, and include alignment pins for placement on the PCB. The pins may also provide connection to ground and feed pads. As shown in FIG. 5G, the J-shaped BLE antenna can be formed using a laser direct structuring (LDS) process as an injection-molded plastic part plated with metal, and may include snap features on a bottom of the molded part for use in placement and alignment on the PCB.

[00162] Detailed schematics of the J-shaped BLE antenna are provided in FIGS. 5H-5L. FIGS. 5H-5K show detailed schematic views of the BLE antenna provided from front, side, rear, and bottom views, respectively, while FIG. 5L provides a perspective view of the BLE antenna. Dimensions of the antenna and design tolerances on the dimensions are provided in the figures in millimeters (mm). The dimensions provided are illustrative, and the BLE antenna can be scaled up or scaled down relative to the dimensions shown depending on the particular application in which the BLE antenna element is to be used. In the embodiment shown in the figures, the dimensions of the antenna are set such that an overall length of the antenna enables the antenna to resonate at a desired frequency in the 2.4 GHz range, for example by setting an overall length of the radiation element to approximately ¼ wavelength at 2.4 GHz. Moreover, the radius of curvature of the J-shaped antenna may be set to maximize the radius of curvature of the antenna within the space constraints imposed by the cavity of the medallion within which the antenna is located while ensuring that the antenna does not contact a metallic outer ring of the medallion.

[00163] In embodiments in which the J-shaped BLE antenna is formed using a laser direct structuring (LDS) process as an injection-molded plastic part plated with metal, the rear surface (shown in FIG. 5 J) may be formed of the injection-molded plastic part while the front surface (shown in FIG. 5H) may be substantially fully plated with metal. The metal plating formed on the front surface may extend to the rear surface, and may notably extend to those portions of the rear surface shown in gray shading in FIG. 5J. In particular, the metal plating may extend along a top edge 521 of the J-shaped antenna to the rear surface of the antenna and thereby provide an antenna ground terminal that is electrically connected to a ground terminal of the PCBA 511. The metal plating may further extend onto a side protrusion 523 of the J-shaped antenna to the rear surface of the antenna and thereby provide an RF signal terminal that is electrically connected to the PCBA 511. In operation, the PCBA 511 may thus apply signals between the ground terminal (at 521) and the RF signal terminal (at 523) in order to emit BLE signals using the antenna, and may sense signals at those terminals in order to receive BLE signals using the antenna.

[00164] Additionally, as shown in the cross-sectional view shown in FIG. 51, the J-shaped antenna has a non-planar profile including two bend points used to elevate the antenna element above the ground plane of the PCBA 511. By spacing the antenna element high above the ground plane, the antenna element is capable of radiating more RF energy. Finally, comers of the J- shaped antenna can be formed by laser trimming so as not to be right angled (90 degree) in order to enable fine frequency tuning.

[00165] FIG. 6 is a block diagram showing functional components of a medallion 11. The components shown in FIG. 6, including the microprocessor 603, memory 601, transceivers 607 and 609, and sensor 605, form part of the PCBA 511 shown in FIGS. 5B-5E.

[00166] As shown in FIG. 6, the medallion 11 includes a memory 601, microprocessor 603, optional sensor(s) 605 such as an accelerometer, one or more transceivers 607, 609 and associated antennas 513, 515, and the battery 507. The components may be communicatively and/or electrically connected to each other by circuits integrated in the PCB of the PCBA 511. In particular, the memory 601 is communicatively connected to the microprocessor 603, such that machine-executable programming instructions stored in the memory 601 can be executed by the microprocessor 603 to cause the medallion 11 to perform functions such as those described throughout this disclosure. In addition to programming instructions, the memory 601 stores a unique identifier used by the guest engagement system 10 to uniquely identify each medallion. The memory 610 can also store encryption and decryption keys, and encrypted data. For example, in one example, the memory stores both a public identifier for the medallion 11 that uniquely identifies the medallion and is broadcast in the beacon signal emitted by the medallion, and a private identifier that also uniquely identifies the medallion, is stored in an encrypted format in the memory, and is used to securely authenticate the medallion (e.g., for use in payments and for unlocking doors). Additionally, the microprocessor 603 is communicatively connected to one or more optional sensors 605, such as an accelerometer sensor, and to one or more transceivers 607, 609.

[00167] As noted above, the medallion includes at least one transceiver and associated antenna configured for wireless communication with the guest engagement system 10. As shown, the medallion 11 includes two transceivers each operating according to a different communication standard. In the example, a first transceiver 607 operates according to the BLE standard, and is connected to an associated antenna 513 used for BLE communications, while a second transceiver 609 operates according to the NFC standard (e.g., a radio-frequency identification (RFID) standard), and is connected to an associated antenna 515 used for NFC communications. While each transceiver is shown as having a dedicated antenna in FIG. 6, in some embodiments two or more transceivers may share a same antenna. [00168] As described above, the BLE transceiver and antenna is used by the medallion 11 to emit periodic beacon signals that enable the guest engagement system 10 to determine the location and identity of a guest and provide services to the guest. The BLE transceiver and antenna can also be used for secure communications. The operation of the BLE transceiver and antenna, however, generally requires that the battery 507 provides sufficient power to the medallion 11 for operation. When the charge level of the battery 507 falls below a threshold, and/or the battery or BLE transceiver fails, the medallion 11 may be unable to communicate using BLE signals. In such situations, the medallion can nonetheless operate as a passive NFC/RFID device. In particular, to function as a passive NFC/RFID device, the medallion does not require any power from the battery for operation. Instead, the medallion operates based on power harvested through the NFC antenna from radio frequency signals inducing current flow in the antenna. When operating as a passive NFC/RFID device, the medallion may be configured to transmit signals including the medallion’s unique identifier in response to receiving RFID interrogation signals or other signals inducing sufficient current flow in the antenna. The guest engagement system 10 may thus be able to provide limited services to guests even if the guests’ medallions do not receive sufficient operating power from their batteries.

[00169] When the battery 507 provides sufficient power for operation of the BLE transceiver, the medallion 11 is configured to operate using three distinct modes of operation. Specifically, the memory 601 stores programming instructions which, when executed by the microprocessor 603, cause the medallion 11 to operate according to a selected one of the three modes of operation. Initially, when a medallion 11 is first activated by being provided with a battery 507, the medallion 11 operates in the sleep mode of operation. The sleep mode of operation is a very low power mode of operation which conserves battery power. In the sleep mode of operation, the medallion 11 listens periodically for network advertisements from a recognized guest engagement system 10 and remains in the sleep mode of operation as long as an advertisement is not received from a recognized guest engagement system 10. In the sleep mode of operation, the medallion 11 listens for network advertisements on a periodic schedule - such as once every 30 seconds, once every minute, once every 5 minutes, or the like. If a network advertisement is received during a periodic listen period, the medallion 11 determines whether the advertisement is for a recognized guest engagement system 10 and, upon determining that the advertisement is from a recognized guest engagement system 10, the medallion 11 switches to the bi-directional mode of operation.

[00170] In the bi-directional mode of operation, the medallion 11 is configured to both emit a beacon signal via the BLE transceiver 607 and antenna 513, and to listen for communications from the recognized guest engagement system 10 via the BLE transceiver 607 and antenna 513. The medallion 11 may additionally listen for communications via the NFC transceiver 609 and antenna 515 in the bi-directional mode of operation. The medallion 11 listens for communications from the recognized guest engagement system 10 on a periodic basis in the bi-directional mode of operation, for example every 10 ms, every 100 ms, or the like. Further detailed information on the bi-directional mode of operation is provided below in relation to the description of the door lock. The medallion 11 may continue to operate in the bi-directional mode of operation until the medallion 11 receives a communication from the recognized guest engagement system 10 causing the operating mode to switch to the beacon mode of operation. The bi-directional mode of operation may consume higher power than the sleep mode of operation.

[00171] In the beacon mode of operation, the medallion 11 is configured to emit the beacon signal via the BLE transceiver 607 and antenna 513. Optionally, the medallion may periodically listen for communications from the recognized guest engagement system 10 via the BLE transceiver 607 and antenna 513, but the listen time periods occur less frequently (e.g., every second, every 5 s, or the like) in the beacon mode of operation than in the bi-directional mode of operation. As a result, the beacon mode of operation is associated with a lower power consumption than the bi-directional mode of operation, but a higher power consumption than the sleep mode of operation. The periodic listen periods in the beacon mode of operation are used to listen for communications from the recognized guest engagement system 10 causing operation mode to switch to the bi-directional mode of operation.

[00172] In both the bi-directional and beacon modes of operations, periodic beacon signals are transmitted from the medallion 11. In general, the beacon signals include a unique identifier of the medallion, and are transmitted on a periodic basis (e.g., every 10 ms, every 100 ms, every second, or the like). The beacon signals can be sensed by sensors 15 of the recognized guest engagement system 10, and used by the guest engagement system 10 to determine the approximate position of the medallion 11 within the facility. The beacon signals are also used by the recognized guest engagement system 10 to provide services to the guest, as described in more detail below.

[00173] The medallions 11 communicate wirelessly with the sensors 15 of the recognized guest engagement system 10 to enable the guest engagement system to provide automated engagement with users or guests of the facility in which the sensors 15 are mounted. While the sensors 15 can be mounted throughout the facility, some sensors 15 are mounted in or otherwise associated with a particular interface device 17 or interface function of the system. As shown in FIG. 1A, interface devices 17 include door locks 17a, automatic doors or turnstiles, vending terminals 17b, cash registers, slot machines, interactive displays 17c or portals 17d, and the like. A particular interface device 17, which provides functionality of a door lock 17a, is described in detail below with respect to FIGS. 7A-7I.

[00174] The door lock 17a provides guests the ability to gain access to their cruise ship stateroom, resort room, or other limited access facility (e.g., a VIP lounge, spa, fitness facility, elevator bank, or the like) simply by walking up to the door, reaching out to grasp the handle, and opening the door that is automatically unlocked based on wireless communications with the guests’ medallions 11. Specifically, the door lock 17a detects the presence of a medallion 11 in front of (or in close proximity to) the door and unlocks the door for permitted guest(s) or service personnel (e.g., stateroom stewards, maids, or facilities engineers). Additionally, the door lock 17a can include a display panel that provides a visual and audio greeting to the guest and can provide real-time information about the guest’s up-coming activities, and/or messages from the crew, staff, or other members of the guest’s party. The door lock display panel can include a panel-mounted camera used to record images and video of unauthorized persons attempting to access the room as well as images of crew, staff members, and others who access the room. [00175] FIGS. 7A-7I illustratively show an automated door lock assembly 700 that provides the functionality of the door lock 17a to automatically unlock a door based on an interaction with a guest’s medallion 11. As shown in FIG. 7 A, the automated door lock assembly 700 can be used on a ship (e.g., a cruise ship) or a hotel to selectively unlock the door of a guest’s room (e.g., a state room or hotel room). Specifically, the automated door lock assembly 700 can be used to selectively unlock the door of a guest’s room to allow entry into the room. In general, the door remains unlocked at all times from the inside of the room, to allow guests to exit the room unimpeded. [00176] The automated door lock assembly 700 includes a latch assembly 701 shown in more detail in FIGS. 7E, 7G, and 71, a door lock module 703 that selectively unlocks the latch assembly 701, and an access panel 705 mounted proximate to the door. The latch assembly 701 includes a latch and a door handle, knob, or other mechanical component(s) that provide door handle/knob functionality, and is generally mounted within the door that it controls. The latch assembly 701 also includes an electronically controlled locking and unlocking mechanism, such as a locking mechanism controlled by a solenoid. The locking and unlocking mechanism of the latch assembly 701 is controlled by the door lock module 703, which is an electronic module operative to send locking and unlocking signals to the electronically controlled locking mechanism. The latch assembly 701 will generally also include a mechanical locking and unlocking mechanism, such as a key -based mechanism that enables the door to be unlocked using a physical key.

[00177] The door lock module 703 is electrically connected to the latch assembly 701, and more specifically to the locking mechanism of the latch assembly 701, by a wire or other conductor. The door lock module 703 generally is battery powered and is mounted within the door, although the door lock module 703 can be placed in different locations depending on implementation. A same battery may be used to power both the door lock module 703 and the electronically controlled locking and unlocking mechanism of the latch assembly 701. In addition to controlling the electronically controlled locking mechanism, the door lock module 703 communicates wirelessly with the access panel 705 from which it receives instructions to unlock the door.

[00178] The access panel 705 communicates wirelessly with the door lock module 703, and provides instructions to unlock the door to the door lock module 703. The access panel 705 also communicates wirelessly with guests’ medallions 11 and determines, based on a secure read of information stored in a guest’s medallion 11, whether or not to instruct the door lock module 703 to unlock the door. The access panel 705 additionally communicates with a central reservation server 21 of the guest engagement system 10 to securely retrieve information on guests permitted access to the door, and determines whether or not to instruct the door lock module 703 to unlock the door based on whether the information obtained from the guest’s medallion 11 (e.g., a unique encrypted identifier) matches that of a guest permitted access to the door. While the access panel 705 can be battery powered, the access panel 705 generally receives power from an external source (e.g., via power over Ethernet (POE)). In some examples, the access panel 705 communicates wirelessly with the central reservation server 21, for example via a Wi-Fi network. Generally, however, the access panel 705 is connected to a wired network (e.g., an Ethernet network) through which it communicates wirelessly with the central reservation server 21 and through which it receives electrical power for operation. Note that the access panel 705 may be connected to an uninterruptible power supply (UPS) so as to be able to continue to function even if power received from a power grid or generator is interrupted.

[00179] FIGS. 7C and 7D provide detailed views of an illustrative access panel 705. As shown in the figures, the access panel includes a flat-panel display (e.g., a 7” touch sensitive display), an integrated camera, and wireless transceivers and associated antenna(s) for communicating with medallions 11 via BLE and/or NFC. The flat-panel display can be used to provide greetings to guests for whom the door in unlocked, to provide information to guests for whom the door in not unlocked, as well as to provide other information. Further functions of the access panel 705 are described in more detail below.

[00180] FIGS. 7E, 7G, and 71 provide exploded views of the latch assembly 701, including the door handle/knob and door latch mechanism. Additionally, FIG. 7E shows the door lock module 703 that can be located within the casing of the latch assembly 701 and that controls operation of the electronically controlled unlocking mechanism of the latch assembly 701. [00181] Additionally, as shown in FIGS. 7E, 7G, and 71, the latch assembly 701 includes electrical isolation sleeves mounted on the spindle of the door handle and configured to electrically isolate the door handle from other portions of the latch assembly 701. For example, the electrical isolation sleeves may isolate the door handle from the latch mechanism. The electrical isolation of the door handle can enable the door handle to be used by the door lock module 703 as a communication antenna for its ISM radio. The electrical isolation of the door handle can further enable the door lock module 703 to monitor a capacitance of the door handle and identify changes in the capacitance of the door handle. In one example, the door lock module 703 measures changes in an electrical potential of the door handle by charging the door handle to a nominal voltage (e.g., 0.05 V) and determining when the electrical potential of the door handle has returned to zero. The monitoring of capacitance performed by the door lock module 703 enables the door lock module 703 to determine when a person touches, contacts, or is in close proximity (e.g., less than a few centimeters) to the door handle so as to activate the unlocking mechanism of the latch assembly 701 only when a person contacts or is in close proximity to the door handle.

[00182] FIG. 7F shows a semi-transparent view of an alternative latch assembly 701. As shown, the latch assembly includes an LED status indicator, shown as a translucent ring-shaped indicator disposed around a base of the door handle, that is used to provide status information of the door latch assembly. In one example, the LED status indicator may provide green illumination when a guest is authorized to open the door and provide red illumination when a guest is denied authorization to open the door.

[00183] FIG. 7H is a block diagram illustratively showing components of the door lock module 703 and of the access panel 705. As shown in FIG. 7H, the door lock module 703 includes a microprocessor controlling operation of the door lock module 703, and a memory storing instructions for execution on the microprocessor. The door lock module 703 additionally includes a sensor, such as a radio frequency (RF), infrared (IR), or capacitive proximity sensor, used to determine when a guest’s hand contacts or comes into close proximity to the door handle. The door lock module 703 additionally includes a short-range radio, such as a radio operating on the ISM band, for encrypted wireless communication with the access panel 705. The door lock module 703 is powered by a battery and a voltage boosting converter such as a 4.5 V boost converter.

[00184] The access panel 705 includes a microprocessor controlling operation of the access panel 705, and memory storing instructions for execution on the microprocessor. The access panel 705 additionally includes a short-range radio, such as a radio operating on the ISM band, for encrypted wireless communication with the door lock module 703. The access panel 705 can include a back-up battery for providing back-up power, and generally includes a power supply receiving electrical power from an external source such as power received over an Ethernet cable. The access panel 705 additionally includes one or more transceivers and associated antennas for communicating with medallions 11, such as a BLE transceiver and antenna and an NFC transceiver and antenna. In some examples, the antenna(s) of the access panel 705 are specifically designed to wrap around an outer edge of the display of the access panel 705. Additionally or alternatively, the access panel 705 may be associated with (and connected to) a spotlight sensor 15 that is disposed on a ceiling directly in front of the door, and operation of the access panel 705 may be based on beacon signals detected by the spotlight sensor 15 and emitted from medallions 11 of guests located directly in front of the door. Additionally, a network transceiver enables the access panel 705 to communicate across a wired or wireless network, such as across the communication network 19 of the guest engagement system 10 with a central reservation server 21. In general, each access panel 705 is associated with one particular door that it is located adjacent to, and the access panel 705 is associated one-to-one with the door lock module 703 of that one door such that the access panel 705 can only control unlocking of the one door and the door lock module 703 operates in response from commands from only that access panel 705.

[00185] In operation, the latch assembly 701 generally maintains the door in a locked state as a default. The access panel 705 maintains its BLE transceiver (or the BLE transceiver of the associated sensor 15) activated so as to detect any beacon signals transmitted by medallions 11 operating in proximity to the access panel 705. For this purpose, the access panel 705 and/or its associated sensor 15 may be configured to detect beacon signals transmitted by recognized medallions that are within a range of 2-4 feet from the access panel. Thus, when a recognized medallion 11 enters the read range of the access panel 705 and/or its associated sensor 15, the access panel 705 begins to receive the periodic beacon signals transmitted by the medallion 11 and initiates a door unlocking sequence.

[00186] First, based on the timing of receipt of a recognized beacon signal, the access panel 705 determines when the next time period during which the medallion will listen for communications from the guest engagement system 10 will occur. In turn, during the determined time period, the access panel 705 initiates a secure connection to the medallion 11 across which the access panel 705 can request the medallion’s unique private identifier (e.g., using encryption such as elliptic curve cryptography (ECC) encryption). The unique private identifier can take the form of an encrypted code, such as a 48 byte encrypted code, that uniquely identifies the medallion 11. In response to the request, the access panel 705 and medallion 11 establish a secure and/or encrypted communication channel over which the medallion provides its unique private identifier to the access panel 705. In general, the unique private identifier is communicated over an encrypted BLE connection. Once the unique private identifier is received, the access panel 705 activates a lock control unit (LCU) that is operative to consult a local memory to determine whether the guest associated with the unique private identifier and medallion 11 are allowed access to the door at the current time. For this purpose, the access panel 705 maintains in local memory a white list including records of medallions’ unique private identifiers that are allowed access to the door at the current and future times. If the unique private identifier received from the medallion 11 is encrypted, the LCU decrypts the identifier and determines whether the decrypted identifier is on the white list. If the access panel 705 determines that the guest associated with the unique private identifier and medallion 11 is allowed access to the door at the current time (e.g., the unique private identifier is included in the white list), the access panel 705 displays a welcome message on its display screen and initiates door unlocking. In the alternative, if the access panel 705 determines that the received identifier is not listed in the record of identifiers that are allowed access to the door, the access panel 705 consults a reservation server 21 across the network 19 to retrieve updated information (if any) on medallion identifiers that are allowed access to the door. In turn, if the received identifier is not listed among the updated information, the access panel 705 determines that the guest is not allowed access to the door at the current time and optionally activates its camera to capture a picture of the guest and transmits the picture to a central server 21. Note that in cases in which the access panel 705 detects multiple medallions 11 within its vicinity, the access panel 705 performs the above steps for each detected medallion, displays a welcome message in the guest’s language of choice on its display screen identifying each guest associated with a medallion 11 that is allowed access to the door, and initiates door unlocking if at least one of the detected medallions is on the white list.

[00187] As part of unlocking the door, the access panel 705 activates its ISM radio and establishes a secure communication channel with the ISM radio of the associated door lock module 703. Once the secure communication channel is established and the guest or crew member is determined to be allowed access to the door, the access panel 705 transmits an arming code (e.g., a door unlock authorization signal) to the door lock module 703 across the secure ISM channel. The arming code may be sent as a message that is encrypted, for example using a 128- bit advanced encryption standard (AES). In response to receiving the arming code, the door lock module 703 activates the proximity sensor (e.g., a capacitive proximity sensor) so as to monitor when the guest’s (or crew member’s) hand contacts or comes into close proximity to the door handle. Upon determining that the guest’ s (or crew member’ s) hand contacts or comes into close proximity to the door handle, the door lock module 703 activates the unlocking mechanism (e.g., a solenoid) of the latch assembly 701. If the door is unlocked and opened, the door lock module 703 can communicate that the door has been opened to the access panel 705 and the access panel 705 can, in turn, instruct the medallion 11 to return to the beacon mode of operation.

[00188] Optionally, the door lock module 703 can monitor when a person’ s hand contacts or comes into close proximity to the door handle at all times. In turn, if a door unlock authorization signal has not been received from the access panel 705 and the door lock module 703 determines that a person’s hand has contacted or come into close proximity to the door handle, the door lock module 703 may send an unauthorized access attempt signal to the access panel 705. In response to receiving the unauthorized access attempt signal, the access panel 705 activates its camera to capture a picture of the person having attempted to access the door and transmits the picture to a central server 21.

[00189] In embodiments in which the medallion 11 is configured to operate in both the bi directional and the beacon mode of operation, the door unlocking sequence described above can include additional steps. If the medallion 11 is operating in the bi-directional mode of operation, the door unlocking sequence can proceed as described above. Optionally, once the door is determined to be unlocked, the door lock module 703 can communicate that the door has been opened to the access panel 705 and the access panel 705 can, in turn, communicate to the medallion 11 that the medallion can return to the beacon mode of operation.

[00190] If the medallion 11 is operating in the beacon mode of operation, the guest engagement system 10 may need to instruct the medallion 11 to switch to the bi-directional mode of operation in order to enable the medallion 11 to establish the secure communication channel with the access panel 705 and provide the access panel 705 with the medallion’s unique private identifier. For this purpose, the access panel 705 can, in one example, determine based on the timing of receipt of a beacon signal from the medallion when the next time period during which the medallion will listen for communications from the guest engagement system 10 will occur. In turn, during the determined time period, the access panel 705 transmits to the medallion 11 a communication to cause the medallion to switch to the bi-directional mode of operation. For example, the access panel 705 may transmit a request for the medallion’s unique private identifier and, in response to receiving the request, the medallion may switch to the bi-directional mode while continuing to transmit periodic beacon signals.

[00191] In another example, the guest engagement system 10 may cause the medallion 11 to switch to the bi-directional mode of operation prior to the medallion 11 reaching the close proximity of the access panel 705 (e.g., prior to being within 2-4 feet of the access panel 705). In the example, location services provided by the guest engagement system 10 monitor the location of each guest within the facility via the guest’s medallion 11. Specifically, the network 13 of sensors 15 of the guest engagement system 10 continuously monitors beacon signals received from medallions 11 in each sensor 15 of the network and identifies medallions 11 that are in proximity to each sensor 15 based on the received beacon signals and the public identifiers contained therein. Based on the monitoring of the locations of medallions 11, the guest engagement system 10 can determine whether a recognized medallion is nearing a locked door that is associated with the medallion 11. For example, the system 10 may determine that the medallion 11 has entered a hallway that includes a door to which the guest associated with the medallion has access to, or that the medallion 11 has reached a pre-determined vicinity (e.g., 100 feet or less) from such a door. In response to the determination, the guest engagement system 10 causes one or more sensors 15 that are within communication range of the medallion 11 to transmit a wake command to the medallion 11 to cause the medallion 11 to switch to the bi directional mode of operation.

[00192] In the foregoing example, the guest engagement system 10 may additionally send a wake command to the access panel 705 of the door to which the medallion has access as the medallion 11 nears proximity of the door. In response to the wake command, the access panel can begin monitoring its BLE transceiver for any medallions 11 that are within its read range and are on the authorized user list (e.g., white list) stored by the access panel 705.

[00193] The description of the functioning of the automated door lock assembly 700 provided above has focused on BLE-based detection and communications between the access panel 705 and medallion 11. However, both the access panel 705 and medallion 11 are also configured for NFC-based detection and communications, and the access panel 705 also provides functionality for unlocking an associated door based on NFC-based communications. The NFC- based communications can be used, among other use cases, in situations in which a medallion’s battery has run out and the medallion is thus unable to emit BLE-based beacon signals or engage in BLE-based communications. To support NFC-based communication, the access panel 705 periodically emits an NFC read signal or NFC interrogation signal that is used to energize any passive NFC-based devices in its vicinity. If a medallion 11 is located in the vicinity of the access panel 705, the NFC read signal will activate the medallion’s NFC antenna and transceiver and cause the medallion 11 to provide the access panel 705 with an NFC-based response beacon signal including the public identifier for the medallion 11. Based on the received response signal, the access panel 705 can then establish a secure NFC-based communication channel with the medallion 11 and proceed with door unlocking based on an NFC-based unlocking process analogous to the BLE-based unlocking process described above (with the exception that all communications will be performed using the NFC transceiver rather than the BLE transceiver). The NFC-based unlocking process can also be used using NFC-enabled devices other than medallions, including NFC-enabled access cards for example.

[00194] In addition to sensors 15 mounted in interface devices 17, the guest engagement system 10 includes a sensor network 13 of stand-alone sensors 15 disposed throughout the facility (or facilities). Each sensor 15 has a known location, and the sensors 15 in the network 13 are used to track the locations of medallions 11 in the facility by creating a log of each medallion 11 detected by each sensor 15 with an associated timestamp. Further, each sensor 15 can engage in bi-directional communication with medallions 11 within its communication range, including the sensing of medallions 11 through the sensing of beacon and other signals transmitted by the medallions 11 and the transmitting and receiving of signals to and from the medallions 11. Examples of stand-alone sensors 15 are shown and described in FIGS. 8A-8D. Specifically, FIGS. 8 A and 8B show views of a directional or omni directional sensor, while FIGS. 8C and 8D show views of a spotlight sensor. The omni directional sensor has a long communication range (e.g., of 30-50 feet, and up to 100 feet or more) extending in all directions around the sensor; the directional sensor has a similarly long communication range (e.g., of 30-50 feet, and up to 100 feet or more) extending in some (but not all) directions around the sensor. The spotlight sensor has a shorter beam-shaped communication range having a diameter that is adjustable and can reach up to 7-10 feet or more, and the beam-shaped typically has a communication range extending in a selected direction from the sensor for a shorter distance than the omni directional sensor (e.g., 15 feet or less). Note that each sensor’s communication range can be adjusted downwards from the maximum range values detailed above.

[00195] FIG. 8A shows an exploded view of the directional or omni directional sensor that includes an electronics PCB 807 and an antenna PCB 803 mounted between a base plate 811 and a radome 801. The antenna PCB 803 has an antenna element 802 mounted thereon that is communicatively connected to circuitry of the antenna PCB 803. The antenna element 802 has a proprietary shape such as those shown in detail in FIGS. 8E-8H and 8K-8N that confer the directional or omni directional sensitivity to the sensor. The antenna PCB 803 communicates with the electronics PCB 807 through a cable 805, and a connector 809 provides a connection between the electronics PCB 807 and the wired network 19. The sensor 15 can be mounted to or in a ceiling or wall of a facility (e.g., using a connector nut 813), and can be used to monitor and communicate with medallions disposed within the vicinity (e.g., within the communication range) of the sensor. FIG. 8B shows the directional or omni directional sensor when all components are mounted together.

[00196] FIG. 8C shows an exploded view of the spotlight sensor that includes an electronics PCB 807 and an antenna mounted between a base plate 811 and a radome 801. A cosmetic base 814 can further be provided. The antenna PCB 803 has an antenna element 802 mounted thereon that is communicatively connected to circuitry of the antenna PCB 803. The antenna element 802 has a proprietary shape shown in detail in FIGS. 8I-8J that confers the spotlight or spotbeam directional sensitivity to the sensor. The antenna includes an antenna PCB 803 having a foam spacer 804 mounted on a surface thereof, and an antenna element 802 mounted on the foam spacer 804. The antenna PCB 803 communicates with the electronics PCB 807 through a cable 805, and a connector 809 provides a connection between the electronics PCB 807 and the wired network 19. The sensor 15 can be mounted to or in a ceiling or wall of a facility (e.g., using a connector nut 813), and can be used to monitor and communicate with medallions disposed within the vicinity (e.g., within the communication range and beam) of the sensor. FIG. 8D shows the spotlight sensor when all components are mounted together.

[00197] Detailed views of the antenna elements 802 that can be mounted to the antenna PCBs 803 provided in the sensors 15 such as those shown in FIGS. 8A-8D are provided in relation to FIGS. 8E-8M. FIGS. 8E-8H show detailed views of the antenna element 802 provided in a directional sensor such as that shown in FIGS. 8 A and 8B. The antenna element 802 may be designed for wall or ceiling mounting locations within a facility and may provide a directional sensing capability having a broad beam width for procuring linear polarized radiation direction to the front face of the antenna. As shown in the top and side views shown in FIGS. 8E-8G, the antenna element 802 has an inverted-V shape that is generally symmetric about a center line, and includes two tabs extending downwardly from a main surface of the antenna that are used for mounting to the antenna PCB 803. The main surface of the antenna, shown in FIG. 8E, including a rectangular central portion having symmetrical parallelogram-shaped extensions extending from opposing sides of the rectangular central portion. Illustrative dimensions of the antenna element 802, measured in inches, are provided in the figures. The dimensions provided are illustrative, and the antenna element 802 can be scaled up or scaled down relative to the dimensions shown depending on the particular application the antenna element 802 (and associated sensor 15) is designed for. In particular, the dimensions can be selected and adjusted in order to vary the center frequency and impedance matching of the antenna. For example, the dimensions provided may be selected to provide the antenna element 802 with a resonating operating frequency of 2.4 GHz (within the BLE operation range in the ISM band) when corresponding PCB ground spacing and housing dielectric proximity are accounted for. The lower tabs extended downwardly from the main surface of the antenna serve as a feed tap and a ground tap electrically connected to the PCB 803, and also serve to maintain the antenna element 802 at an appropriate height spacing from the PCB ground plane.

[00198] FIGS. 8I-8J show detailed views of the antenna element 802 provided in a spotlight (or spotbeam) sensor such as that shown in FIGS. 8C and 8D. The antenna element 802 may be designed for ceiling mounting locations (or wall mount locations at high elevation with down tilt) within a facility and may provide high gain and a directional narrow-beam (i.e., spotlight) sensing capability procuring circularly polarized (CP) radiation. As shown in the top and side views shown in FIGS. 81-8 J, the antenna element 802 has a generally planar shape, and has a shape of a square having diagonally opposite comers removed at angles of 45 degrees relative to sides of the square. The antenna element 802 of FIGS. 81 and 8J may be mounted to the antenna PCB 803 via a foam spacer 804, as shown in FIG. 8C. Illustrative dimensions of the antenna element 802, measured in millimeters (mm), are provided in the figures. The dimensions provided are illustrative, and the antenna element 802 can be scaled up or scaled down relative to the dimensions shown depending on the particular application the antenna element 802 (and associated sensor 15) is designed for. In particular, the dimensions can be selected and adjusted in order to vary the center frequency, axial ratio, and impedance matching of the antenna. For example, the dimensions provided may be selected to provide the antenna element 802 with a resonating operating frequency of 2.4 GHz (within the BLE operation range in the ISM band) when corresponding PCB ground spacing and housing dielectric proximity are accounted for. [00199] FIGS. 8K-8N show detailed views of the antenna element 802 provided in a circular sensor. For example, the antenna element shown in FIGS. 8K-8N may provide omni directional sensing, and may be used within a sensor 15 such as that shown in FIGS. 8 A and 8B. The antenna element 802 may be designed for ceiling mounting locations within a facility and provide a linear polarized broad beam width for procuring an azimuth omni-directional sensing pattern. As shown in the top and side views shown in FIGS. 8K-8M, the antenna element 802 has a generally symmetric shape about a center line, and includes two tabs extending downwardly from a main surface of the antenna that are used for mounting to the antenna PCB 803 (as shown, e.g., in FIG. 8 A). The main surface of the antenna shown in FIG. 8K has a generally circular shape. Illustrative dimensions of the antenna element 802, measured in inches, are provided in the figures. The dimensions provided are illustrative, and the antenna element 802 can be scaled up or scaled down relative to the dimensions shown depending on the particular application the antenna element 802 (and associated sensor 15) is designed for. In particular, the dimensions can be selected and adjusted in order to vary the center frequency and impedance matching of the antenna. For example, the dimensions provided may be selected to provide the antenna element 802 with a resonating operating frequency of 2.4 GHz (within the BLE operation range in the ISM band) when corresponding PCB ground spacing and housing dielectric proximity are accounted for. The lower tabs extended downwardly from the main surface of the antenna serve as a feed tap and a ground tap electrically connected to the PCB 803, and also serve to maintain the antenna element 802 at an appropriate height spacing from the PCB ground plane. The feed and ground taps can provide for different current flow directions on the surface of the antenna radiation element 802.

[00200] In general, the sensors 15 mounted in interface devices 17 of the guest engagement system 10, such as the antennas of access panels 705 used to unlock doors, are adjusted to have limited range (e.g., 2-4 feet) so as to only sense medallions 11 of guests that are in close proximity to the interface devices 17. Additionally, the sensors 15 of interface devices 17 can be directional or spotlight type sensors operative to detect medallions 11 in only selected directions. In this way, a sensor associated with an access panel 705 may be operative to only detect medallions 11 that are disposed within a limited distance in any direction from the sensor, while a sensor of a payment terminal or vending machine may only detect medallions 11 that are disposed within a limited angular range (e.g., directly in front of the payment terminal or vending machine) and within a limited distance (e.g., less than 2 feet) from the sensor.

[00201] As noted above, the sensors 15 are disposed throughout the facility, and are used to monitor the locations of medallions 11 throughout the facility and provide services to guests based on the sensed signals. Specifically, the sensors 15 are used by the guest engagement system 10 to provide location information to the guest engagement system 10 at selectable levels of precision. At a low level of precision, the location of a medallion 11 is identified based on the identity(ies) of the one or more sensors 15 or other devices that detect beacon signals from the medallion 11 at any given time. In this way, the position of the medallion at any time can be approximated based on the known positions of the sensor(s) (and/or positions of other devices, if known) having detected the medallion’s most recently detected beacon signal(s). In order to determine the position of a medallion 11 at a higher level of granularity, the position of the medallion is determined based on the relative received signal strength of the beacon signal measured at each of the sensor(s) having received the beacon signal, and/or based on characteristics of the sensing range and sensing beam (e.g., sensing range and sensing direction) of the sensor(s). In particular, when beacon signals from a medallion 11 are received by three or more sensors 15, the relative received signal strength of the beacon signal at each of the sensors 15 (and/or the delay between reception times of the beacon signal at each of the sensors 15) can be used to triangulate the position of the medallion 11 relative to the known locations of each of the sensors 15.

[00202] The monitoring of the locations of medallions 11 within the facility can be performed not only by sensors 15 of the sensor network 13 but also by sensors 15 mounted in interface devices 17 of the guest engagement system 10. For example, the access panels 705 of automated door lock assemblies 700 located throughout the facility can be used to detect all medallions 11 passing by the access panels 705. The access panels 705 can relay the identity of all detected medallions 11 to a central location server which maintains a log of all medallions’ locations with associated timestamps. Additionally, the monitoring of locations can be performed through sensing of medallions 11 by BLE- or NFC-enabled devices, such as BLE- or NFC-enabled mobile devices, tablet computers, or interactive displays that are in communication with servers 21 of the guest engagement system 10. The BLE- or NFC-enabled mobile devices, such as guests’ mobile devices or staff members’ tablets, may detect medallions 11 located within the devices’ communication ranges and report to the central location server the identities of detected medallions 11 along with timestamps of detection and location information for the device (if available).

[00203] In order to provide continuous real-time monitoring of the locations of medallions 11, each of the sensors and devices that detect medallions 11 relay the identity of all detected medallions 11 along the time-of-detection timestamps to a same central location server. The central location server thus maintains a log of all medallions’ locations with the associated timestamps. The central location server can thus be used to identify each medallion’s most recent detected location based on the most recent log entry for the medallion 11 or, if appropriate, based on two or more of the most recent entries in the log for the medallion 11 (e.g., to provide increased location accuracy by combining two different location sensing methodologies). In this way, the guest engagement system 10 provides real-time (or near real-time) evaluations of each medallion’s location. The location information can further be used by the guest engagement system 10 to provide additional services to guests or others, for example to provide notification events to systems that are used to activate personalized interactions when a medallion 11 is determined to arrive in an area, move around an area, linger in an area for a determined amount of time, or exiting an area or space equipped with sensors 15.

[00204] The location-based services can further be enhanced through the use of sensors 15 located near points of entry and/or exit from a facility. Specifically, if the last entry relating to a particular medallion 11 in the log maintained by the central location server is for an entry/exit location - and the log does not include any further detections of the medallion 11 at later times in the facility - the system may determine that the medallion 11 (and its associated guest) have exited the facility. In turn, when the medallion 11 is once again detected at the same (or a different) entry/exit location, the medallion may be determined to have re-entered the facility. The guest engagement system 10 may thereby maintain a log of medallions 11 that are in the facility and a log of medallions 11 that have exited the facility. Notification can be provided to users based on these logs, for example to inform another guest that their family member has exited the facility and/or returned to the facility.

[00205] In addition to the functions described above, the guest engagement system 10 can additionally be used for maritime mustering, emergency evacuations, or the like. Specifically, since the guest engagement system 10 includes sensors 15 throughout the facility (or ship) that are configured to monitor the positions of medallions 11, the guest engagement system 10 maintains current up-to-date information on guests’ locations within the facility at all times based on the monitored locations of all guests’ medallions 11. Based on the current information on guests’ locations, the guest engagement system 10 can dynamically assign guests to mustering stations or evacuations routes when a mustering or evacuation operation is undertaken. Specifically, the guest engagement system 10 can dynamically assign guests to mustering stations or evacuations routes in such a way as to assign guests to the mustering station or evacuation route that is closest to their current position when the mustering or evacuation operation is triggered. The guest engagement system 10 can additionally or alternatively dynamically assign guests to mustering stations or evacuation routes so as to avoid overloading a particular mustering station or evacuation route when the mustering or evacuation operation is triggered. For example, in situations in which a large number of guests are concentrated within a certain portion of the facility (e.g., a large number of guests are in or near the stern of the ship), the dynamic assignment may be used to assign certain guests to mustering stations or evacuation routes in or near the bow of the ship to ensure that no mustering station or evacuation route is overloaded with guests. Additionally, the guest engagement system 10 can monitor the position of medallions and guests during the mustering or evacuation operation, and dynamically change a particular guest’s assigned mustering station or evacuation route based on updated real-time information obtained based on the real-time monitoring of guests’ changes in location (i.e., movement) through the facility. In this manner, a guest’s assigned mustering station or evacuation route can be updated if the guest follows an unexpected route during the mustering or evacuation operation, for example if the guest follows an unexpected route to retrieve a child during the mustering or evacuation operation or if the guest must divert around a smoke-filled corridor during the evacuation.

[00206] The guest engagement system 10 can further be used to automatically identify rooms that are cleared of all guests during the mustering or evacuation operation, for example by determining that no medallions are present in the room and/or determining that all guests associated with the room are located elsewhere in the facility (based on the monitored locations of the guests’ medallions). Conversely, the guest engagement system 10 can be used to automatically identify rooms that have guests present therein during the mustering or evacuation operation (based on the monitored locations of the guests’ medallions), and to direct crew and/or emergency responders to the identified rooms to assist guests in the evacuation.

[00207] The above-identified features of the guest engagement system 10 used in mustering and/or evacuations are enabled, in part, by the guest engagement system’s ability to communicate information to guests during the mustering or evacuation operation. For this purpose, the guest engagement system 10 relies on the access panels 705, interactive displays 17c, portals 17d, and the like that are located throughout the facility. Specifically, the guest engagement system 10 provides mustering and/or evacuation instructions on the displays of interface devices 17, such as arrows (or more detailed instructions) pointing towards mustering stations and evacuation routes. The instructions can additionally be customized to the individual guests whose medallions are detected in the vicinity of each interface device 17, for example to instruct one guest to evacuate in a particular direction while instructing a different guest to evacuate in another direction (e.g., to enable the other guest to regroup with other guests in his/her party). The instructions can also provide information to guests regarding other guests in a same party, for example to provide a guest with information on the current location, assigned mustering location, and/or assigned evacuation route of the guest’s child, spouse, or friend. The instructions can also be customized for each guest to display in the guest’s language of choice.

[00208] The guest engagement system 10 provides services and engagement with guests through a variety of different modalities and terminals. For example, as shown in FIG. 9, the guest engagement system 10 can provide services and engagement through end devices 18 such as mobile devices 18a (e.g., smartphones), tablet computers 18b, interactive displays 18c (e.g., touch-enabled display screens), web-enabled televisions (e.g., stateroom televisions), desktop computers 18d and/or web interfaces, kiosks, among others. In general, an end device 18 includes a processor, memory storing program instructions, a display, and a user input interface such as a touch-screen, although additional components (or fewer components) may be used. Some end devices 18, including interactive displays 18c, web-enabled televisions, kiosks, and the like, may also function as interface devices 17, and vice versa. In particular, end devices 18 that are BLE-enabled (e.g., include a BLE transceiver) can generally function as interface devices 17. Conversely, interface devices 17 that include a user input interface and provide access to the guest engagement application described in more detail below can function as end devices 18. [00209] The services and engagement provided by the guest engagement system 10 may be provided through an application or other executable program stored on and executed by the end devices 18 such as a dedicated guest engagement application. The services and engagement may alternatively or additionally be provided through web-based interfaces, such as a guest engagement interface executed on a server 21 accessed through a web browser executed by an end device 18 and having a communication connection to the server 21. The services and engagement generally rely at least in part on data and information retrieved from the servers 21 of the guest engagement system 10 via network connections (e.g., Internet connections) of the end devices 18, although certain services and engagement can be provided without network connections or without retrieving data and information from the servers 21. For purposes of communicating with the servers 21, the end devices 18 are shown in FIG. 9 as having wireless (e.g., in the case of end devices 18a and 18b) or wired (e.g., in the case of end devices 18c and 18d) connections to the servers 21 through the communication network 19. Note that communication network 19 can include one or more of a local area network (LAN), a wide area network (WAN), the Internet, and the like.

[00210] As shown in FIG. 9, some of the end devices 18 through which services and engagement are provided may be BLE-enabled devices, such as BLE-enabled mobile devices 18a, tablet computers 18b, or interactive displays 18c. When such an end device 18 executes the guest engagement application, the guest engagement application may optionally activate the BLE transceiver of the end device 18 to provide additional services to a user. For example, the guest engagement application may activate the BLE transceiver of the end device 18 and use the activated BLE transceiver to listen for beacon signals emitted by medallions 11 located within a BLE communication range of the end device 18. The guest engagement application may optionally report to the servers 21 the identifiers of medallions 11 from which beacon signals were received along with a timestamp of receipt and location information for the end device 18 (when available). The guest engagement application may further use the activated BLE transceiver to engage in two-way communication with medallions 11 from which beacon signals were received. In one example, the guest engagement application may cause the mode of operation of a medallion 11 to change. In one use case, the guest engagement application may cause the BLE transceiver of the end device 18 to emit an advertisement from the guest engagement system, so as to cause any medallion 11 in its communication range to exit the sleep mode when the medallion 11 detects the advertisement. In another use case, the guest engagement application may cause a medallion 11 operating in the beacon mode to enter the bi directional mode or the sleep mode of operation, or cause a medallion 11 operating in the bi directional mode to enter the beacon mode or the sleep mode of operation.

[00211] In some instances, the guest engagement application may additionally or alternatively activate the NFC transceiver of an end device 18 when the application is executed on an NFC-enabled end device 18. In such situations, the application can be used to detect medallions 11 and engage in communication with medallions 11 via NFC. In particular, while the description herein is focused on BLE-based communications between end devices 18 and medallions 11, the features described in the BLE-based context can similarly be enabled through NFC-based communication between the end device 18 and medallions 11 when using an NFC- enabled end device 18.

[00212] References to the guest engagement application throughout this document refer not only to instances in which the guest engagement application takes the form of an application or other executable program stored on and executed by an end device 18 but also refer to instances in which the guest engagement application takes the form of a web-based interface or other terminal-based interface. In general, user interfaces provided through application-based and web-based interfaces will be similar, although certain functionalities of the guest engagement application may only be offered on application-based or on web-based interfaces. Additionally, references to the guest engagement application may refer to different versions of the application, including guest-focused versions that include only functionalities offered to guests, staff-focused versions that include additional functionalities offered to hosts or staff, supervisor-focused versions that include functionalities offered to supervisors overseeing staff members, and administrator versions that include functionalities offered to system administrators only.

[00213] In order to use the guest engagement application through an end device 18, a guest generally needs to identify and authenticate themselves. If not identified and authenticated, the guest may only have access to limited features of the application and the guest may notably not have access to user profile-based information. In instances in which the guest engagement application runs on a BLE-enabled end device 18, the guest engagement application can listen for BLE beacon signals from guests’ medallions 11 and, in response to detecting one or more beacon signals, can provide a log-on page personalized for the guest(s) that are automatically identified based on the detected beacon signals. Guests can then authenticate themselves to log into the application by entering a password or personal identification number (PIN) into the application. If the application runs on an end device 18 that is not BLE-enabled, and/or if a guest’s medallion beacon signal is not detected by the application, a guest can identify and authenticate themself to log into the application by entering both a username and a password or personal identification number (PIN) into the application. Note that when the application runs on a guest’s own mobile device 18a, the guest can select to remain logged into the application in order not to have to enter a password or PIN each time the guest accesses the application. Otherwise, the guest may be automatically logged out of the application if no user interaction occurs for a pre-determined length of time. Additionally, in cases in which log-on was based on detecting a medallion beacon signal, the guest may be automatically logged out if the medallion beacon signal is no longer detected by the application or end device 18 for a pre-determined length of time or if the medallion 11 is determined to have stepped away from the end device 18. [00214] Once logged in, the application may automatically access and securely retrieve profile information associated with the identified and authenticated guest from the servers 21. The application can also be used to prompt a guest to provide, complete, or review missing profile information that is then uploaded from the application to the servers 21. Profile information may include a name, identity photograph, booking and other reservation information, payment information (e.g., information on stored payment modalities for the guest), and the like. The profile information can also include additional data associated with the guest, including information on the guest’s past, present, and future activities (determined based on bookings and reservations and on location data), past, present, and future locations (determined based on bookings and reservations and on location data), past, present, and scheduled future orders and preferences, and the like. The profile information can also include pictures, music, video, and other types of data associated with the guest.

[00215] Through guest-focused versions of the application, the guest engagement system 10 provides a variety of services to guests. For example, a guest using of the application can use the application to review the guest’s bookings, registration, and reservations, including past, present, and future registrations for lodging, restaurants, shows, activities, and the like. The guest can also use the application to receive information on and make reservations for available lodging, restaurants, shows, activities, and the like. The information may be based on recommendations for future bookings, registrations, and reservations personalized for the guest based on the guest’s profile information. The guest can also use the application to review photographs, videos, and other media items make available by the guest engagement system 10, including photographs, videos, and other media items that are associated with the guest. The association of media items with the guest can be based on matching guest profile information with tagged information for the media items, such as profile and tag information indicating that a video was taken at a location visited by the guest’s medallion, profile and tag information indicating that a photograph includes a person associated with the guest based on the person’s medallion having been detected in proximity to the photographer at the time the photograph was taken, or the like. The application may also provide access to games (optionally including wager- based games), shopping, and other functionalities.

[00216] The guest engagement system 10 may also allow guests to view live shows using the guest-focused version of the application. The show can be viewed, for example, through the guest’s stateroom television on which the guest engagement application can be accessed. In detail, the guest using the guest engagement application may select to view a live show through the application, such as a show occurring in a theater or other venue within the facility in which the guest engagement system 10 is installed or outside of the facility. In response to the selection, the guest is presented with a live audio and/or video stream of the event. Additionally, the application allows the guest to interface with a performer participating in the live show. In detail, the application can allow the guest to send instant messages or other feedback to the performer for example by typing a message for the performer on an user input interface of the application (e.g., an on-screen keyboard or a remote control for a stateroom television) or selecting a feedback button (e.g., a “clap” button, a “laugh” button, a “thumbs-up” button, a “heart” button, or the like). The instant messages and feedback are then displayed on a screen provided in front of the performer and/or provided as auditory feedback to the performer (e.g., by activating pre recorded clapping or laughing sounds) so as to notify the performer of feedback received from the guest and enable the performer to engage with the guest during the show.

[00217] In some examples, the guest engagement application provides communication functionalities to enable users of the application (including both guests and staff) to communicate with each other using the application. The communication functionalities can include text, audio, and/or video-based communications between users such as chat-based communications, instant messaging (IM), voice-mail or video voice-mail, and the like. In addition, the communications functionalities can allow users to obtain information on other linked users including position information. Linked users can include, in the case of a guest, other guests in his/her party (e.g., other guests that are part of a same reservation, such as children, parents, or the like) or guests who have accepted link request to the guest, or in the case of a staff member, one or more persons for whom the staff member is to provide a service (e.g., a guest having ordered food or drink to be delivered by the staff member). For example, once users are linked, the communication functionality of the guest engagement application may provide general location information to a guest (e.g., to indicate that another guest is in the facility or has exited the facility) and/or precise location information (e.g., to indicate that the other guest is in their stateroom). The communication functionality may also indicate whether another linked guest is available for instant communication and, in some examples, may identify guests having left the facility as being unavailable for communication.

[00218] The guest engagement system 10 provides additional functionality through staff- focused versions of the guest engagement application. The staff-focused versions of the guest engagement application can be executed on end devices 18 used by hosts and staff to provide services and engagement to guests of the facility. Commonly, hosts and staff will access the staff-focused version of the guest engagement application on a tablet computer 18b end device that is BLE-enabled (e.g., the end device includes a BLE transceiver and BLE antenna), although in some situations hosts and staff will access the application through other end devices (e.g., interactive displays 18c, portals, access panels 705 of door locks, and the like).

[00219] In one example, the staff-focused version of the guest engagement application can be used by a staff member to engage with guests. For this purpose, the guest engagement application uses the BLE transceiver of the end device 18 to detect any medallions 11 within the vicinity (e.g., BLE communication range) of the end device 18. Specifically, the BLE transceiver is used to detect beacon signals emitted by medallions 11 within the vicinity of the end device 18. When one or more beacon signals is/are detected, the staff-focused version of the guest engagement application is configured to retrieve the public identifier of each medallion that is included in the emitted beacon signals, and to retrieve from the servers 21 profile information associated with the retrieved identifier(s) and associated guest(s). The retrieved profile information generally includes a photograph and name (or nick-name) associated with the guest. The retrieved profile information is then provided on a display of the end device 18 to enable the staff member or host to engage with the guest(s) based on the retrieved profile information. For example, based on the retrieved profile information, the staff member can visually identify the guest, greet the guest by name or nick-name, and discuss the guest’s upcoming bookings with the guest.

[00220] In situations in which profile information for multiple guests is received by the end device 18, the guest engagement application may display profile information for the multiple guests. In some examples, the profiles may be displayed in an order of estimated distance of each guest from the end device 18, where the estimated distance can be determined based on a signal strength or transmission delay associated with the respective BLE beacon signal associated with each guest’s medallion 11 and detected by the end device 18.

[00221] Based on the retrieved profile information, the staff member or host can assist the guest. For example, the staff member or host can review the guest’s bookings, registration, and reservations; provide information and/or make recommendations or reservations for future bookings, registration, and reservations personalized for the guest based on the guest’s profile information; place orders for drinks and food for delivery to the guest; assist the guest in finding their way through the facility; or the like. The application may also enable the staff member or host to engage in games (optionally including wager-based games) with the guest, and provide further functionalities.

[00222] The guest engagement system 10 can further provide payment functionality through the staff-focused version of the application. As described above, medallions 11 can be used for payments by establishing a secure communication channel between the medallion 11 and a payment terminal (e.g., 17b), authenticating the identity of the medallion 11 across the secure communication channel using the medallion’s unique private identifier or other encrypted information stored in the medallion 11 and, based on the authenticated identity, processing a payment transaction using payment information associated with the authenticated medallion 11. Such payment transactions can be performed over BLE or NFC communications between the medallion 11 and payment terminal (e.g., 17b), and can be performed by vending machines, cash registers, and other payment terminals in which a staff member or cashier need not be present. In addition, a streamlined payment process can be used through the staff-focused version of the application. Specifically, through the staff-focused version of the application, a staff member can perform authentication of the guest through visual recognition of the guest based on comparing the guest’s appearance with the photograph stored in the guest’s profile. In particular, the guest engagement system 10 may prompt a staff member using the staff-focused version of the application to authorize a payment to a guest account. The prompt may be presented in response to the staff member selecting through the application to place an order on behalf of the guest (e.g., an order for food or drink, a registration for an excursion, a booking for seats at a show, a room upgrade, a payment to participate in a game, or the like), for example. The prompt may generally rely on two complementary identification modalities in order to allow the staff to authorize the payment, although different numbers of identification modalities (including a single identification modality) may be used. For example, the prompt may rely on the end device 18 that executes the staff-focused version of the application detecting the medallion 11 of the guest to whom payment is to be charged (e.g., using BLE and NFC communication modalities to detect the medallion 11), retrieving profile information (including a photograph) for the detected medallion 11 from the server 21, displaying the photograph of the guest associated with the medallion 11, prompting the staff member to visually confirm that the guest with whom the staff member is interacting matches the displayed photograph and, upon receiving confirmation from the staff member that the guest matches the photograph, processing the payment. In the example, the two complementary identification modalities used are detection of a medallion 11 and visual confirmation of a guest’s identity, although other modalities (and different numbers and combinations thereof) can be used in other examples.

[00223] The guest engagement system 10 also provides wayfmding functionality, and provides an interface for wayfmding through the guest engagement application. The wayfmding functionality provided by the guest engagement system 10 can be used for wayfmding within a moving reference frame as well as within a fixed reference frame. For example, in the case of wayfmding on a cruise ship, traditional location determination systems such as GPS cannot readily be used for multiple reasons. First, the cruise ship can move, and wayfmding within the ship must therefore be based on the moving reference frame of the ship rather than a fixed (e.g., land-based) reference frame. As a result, GPS-based location determination and other fixed- reference frame location determinations are of limited use since a user’s GPS-based location cannot be used to determine where the user is located relative to the moving ship. Second, the cruise ship includes substantial masses of metal and other surfaces which interfere with the propagation of GPS-based signals (such that GPS signals cannot be received inside the ship) and/or cause substantial signal noise as a result of electromagnetic signals bouncing off of metallic surfaces. As a result, traditional location determination systems are generally not effective for way finding on a ship.

[00224] In order to address the shortcomings noted above, the guest engagement system 10 provides its own wayfmding functionality based on the network of sensors 13 of the guest engagement system 10. In detail, the guest engagement system 10 maintains a database of locations at which medallions 11 have been detected. Each record in the database includes an identifier for the medallion (e.g., the public identifier for a medallion 11 that is broadcast as part of the device’s beacon signal), an identifier for a location (e.g., identifier(s) of the location(s) of the sensor(s) 15 or other antenna or device having detected the beacon signal, and/or a more precise location determination based on tri angulation, multilateration, or other location determining method), and a timestamp. The location determination performed by the guest engagement system 10 can thus be performed based on sensors of the sensor network 13 as well as based on beacon signals detected by end devices 18, by interface devices 17, and the like. As noted previously, the location determination may be performed at different levels of precision depending on the types of sensors 15 through which beacon signals have been detected (e.g., spotlight sensors provide more detailed location information than omni-directional sensors), depending on the number of sensors 15 having detected the beacon signals, depending on whether triangulation, multilateration, transmission delay, or signal strength information from multiple sensors is used, and the like.

[00225] The wayfmding functionality provided by the guest engagement system 10, including the wayfmding provided through the guest engagement application, is thus provided based on location determination performed by the guest engagement system 10. Specifically, a guests’ location is determined by a server 21 of the guest engagement system 10 by determining a location of the user’s medallion 11 and reporting the determined location to the guest through the guest engagement application. For example, the guest location may be displayed superimposed on a map or on a three-dimensional model of the ship shown on a user interface of the application provided on the end device 18 currently in use by the guest. In this way, the guest’s position is not generally determined by the end device 18 in use by the guest, but the guest’s position is instead generally determined by the guest engagement system 10 (e.g., by a server 21 of the guest engagement system 10) based on a location of the guest’s medallion 11 as detected by the sensor network 13 of the guest engagement system 10.

[00226] Note that as described above, the sensor network 13 of the guest engagement system 10 can extend to multiple different facilities including facilities located on and facilities located off of a ship. The guest engagement system 10 can thus be used to provide accurate location determination and wayfmding in any of the facilities, including fixed facilities (e.g., land-based), moving facilities (e.g., ship-based), and facilities including both fixed and moving components (e.g., facilities accessed by cruise passengers during a cruise, which may include both ship-based and land-based facilities). In such cases, the guest engagement system 10 can automatically determine a guest’s position accordingly to the appropriate fixed or moving reference frame depending on whether the guest is currently positioned on a fixed (e.g., land- based) or moving (e.g., ship-based) reference frame, and provide location information through the guest engagement application in the reference frame determined to correspond to the guest’s current position.

[00227] As detailed above, the guest engagement system 10 can determine the position/location of a guest based on the medallion 11, and more particularly based on the locations at which beacon signals emitted by the medallion 11 are detected. The detection relies on operation of the sensors 15 of the system 10, and more specifically on the known location at which each sensor 15 is installed and the sensing range of each sensor (e.g., shape and orientation of a directional sensing range). The detection can also rely on detection of beacon signals by end devices 18 including end devices 18 that have variable locations such as mobile devices 18a and tablet computers 18b. In detail, in the case of end devices 18, the locations of end devices 18 having fixed locations can be stored by servers 21 of the guest engagement system 10 and the stored location information can be used to determine the locations of detected medallions 11. [00228] In the case of movable end devices 18, the guest engagement system 10 can rely on two sources of information to determine a current location of an end device 18 and thereby infer locations of medallions 11 detected by the end device 18. First, the guest engagement system 10 can receive periodic reports from end devices 18 including identifiers of medallions 11 from which beacon signals were detected, and can infer the location of a medallion 11 by determining the location of the end device 18 from which the report was received. The guest engagement system 10 can then determine the location of the end device 18 based on the identity of a Wi-Fi or other wireless access point through which the end device 18 is connected to the communication network 19 of the system 10. For this purpose, the guest engagement system 10 maintains a database identifying the mounting location of each wireless access point in the facility, and uses the database to identify the location of end devices 18 and medallions 11 detected by the end devices 18. The identity of the wireless access point can be reported to the guest engagement system 10 by the end device 18, or determined by the guest engagement system 10 based on header information included in packets received from the end device 18.

[00229] Second, as part of the periodic reports received from end devices 18 and identifying medallions 11 detected by the end devices, the guest engagement system 10 may receive location information of the end devices 18 when such information is available. The location information reported by the end device 18 may be a location determined by the end device 18 based on the end device’s own position determination function such as a GPS-based position determination. In such situations, the guest engagement system 10 can use the reported location information provided by the end device 18 to determine the location of medallions 11 detected by the end device 18. The guest engagement system 10 can further use information on location of the moving reference frame (e.g., a GPS location of the ship on which the end device 18 is travelling) to determine the position of the end device 18 relative to the moving reference frame.

[00230] The wayfmding functionality can be used by the guest engagement system 10 in order to enable a user of the guest engagement application to locate another guest or staff member by tracking the other guest or staff member in real time. This guest tracking functionality can be used by a guest to locate another guest (e.g., a friend, spouse, child, ...) as well as by a staff member or host to locate a guest (e.g., to deliver a food, beverage, or other order, or to assist the guest in another manner), among other circumstances. The guest tracking functionality enables one user of the application to be provided through the guest engagement application with information on the other guest’s current location as determined by the guest engagement system 10, including a display of the other guest’s current location displayed superimposed on a map or on a three-dimensional model of the ship (or other facility) shown on a user interface of the application. The guest tracking functionality also enables the one user to be provided with wayfmding directions to the other guest’s current location based on a combination of the user’s location (determined by the guest engagement system 10 based on the detected location of the user’s medallion 11) and the other guest’s location (determined by the guest engagement system 10 based on the detected location of the other guest’s medallion 11). The locations may be updated in real-time as the user and guest move about the facility, and the wayfmding directions may correspondingly be updated in real-time.

[00231] The functionalities of the guest engagement system 10 described above can enable the following services to be provided (described in the illustrative context of a cruise ship example).

[00232] The guest engagement system 10, through the guest engagement application, enables guests to engage with the system from outside of the facility in which the system is installed. For example, guests can engage from home by accessing their profile through a web- based version of the application or through an end device 18 (e.g., mobile phone 18a, tablet computer 18b, desktop computer 18d, or the like) running the application. Guests can then, at their leisure, populate their guest profile by inputting any required documentation such as passport information, completing health forms and travel details, and inputting a preferred form of payment. The guests can also upload a photo, create a digital avatar to further personalize their profile, and arrange or book services for example to have luggage picked up for expedited delivery direct to their stateroom.

[00233] Guests can further engage when in an airport - notably in cases in which guests have obtained their medallions 11 in advance of travel. For example, in the case of guests travelling to a facility in which a guest engagement system 10 is operative, the guests may be met at the destination airport by staff members. In the example, staff members stationed at the airport may be equipped with end devices 18 running the guest engagement application. The staff members may use the end devices 18 and the application to detect medallions 11 of arriving guests, retrieve profile information for the guests including photographs, and recognize the guests based on the proximity of the medallions 11 and visual recognition of the guests based on the photographs. The staff members can thus personally welcome the guests, confirm their documentation status, and direct them through the airport (e.g., to direct the guests to a fleet of motor coach vehicles destined for a port terminal).

[00234] In transit in the motor coach vehicles, guests can again access the guest-focused application through their end devices 18 (e.g., mobile phones 18a or tablet computers 18b) to explore options provided at the destination facility (e.g., the cruise ship, in one example), book activities and learn more about the people, places and cultures they will come to experience. [00235] Additionally, once at the cruise terminal (e.g., in the cruise ship example), guests may be able to board the ship with minimal further interaction with staff members since the guests are already equipped with their medallions 11 which function as the key to their stateroom. Additionally, staff members in the terminal may use end devices 18 running the staff-focused application to identify arriving guests, identify guests who haven’t yet completed the registration process, and approach those guests in order to assist them with finalizing the process.

[00236] Further examples of interface devices 17 that can be used as part of the guest engagement system 10 are gaming stations 100 such as that shown in FIG. 10. The gaming stations 100 provide environments in which guests can engage in gaming, including wager-based gaming, cooperative gaming with other guests, and head-to-head gaming against other guests. [00237] Each gaming station 100 generally includes ergonomic seating 101 for multiple guests (e.g., four guests in the examples shown in FIG. 10), although a gaming station 100 for a single guest or modular gaming stations 100 for variable numbers of guests can also be used. The seating 101 can position guests across from each other with a central frame positioned between the guests and supporting components of the gaming station. Some guests can also be seated next to each other, as shown in FIG. 10. The gaming station 100 also includes one or more display screens 102 mounted to the central frame and used to display game play screens and images to users, and input devices 103 such as keyboards, touch pads, touch-sensitive displays, or the like, that are mounted to the central frame and used to receive input from users. The input devices 103 can also include microphones (e.g., a microphone array including multiple microphones disposed at different locations in the gaming station 100), optical sensors, and/or ultrasonic proximity sensors used to provide enhanced user input, user position data, and/or user movement data of users within the gaming station.

[00238] The gaming station 100 also includes one or more sensors 15 (not shown) that are mounted within the station 100 (e.g., at hidden or discrete locations) and are used to identify guests currently seated in the station 100 or otherwise using the station 100. The sensors 15 are used to detect medallions 11 of users of the station 100 in order to allow the users to log into the gaming station 100 and engage in gaming. The sensors 15 can also be used to establish secure communication connections to medallions 11 of users of the station 100 to authenticate the medallions 11 and engage in payment transactions. In general, the sensors 15 have sensing beams directed to the seating 101 of the gaming station 100 so as to detect the medallions 11 of guests that are seated in the gaming station 100. In some examples, the sensing beams of the sensors 15 are adjusted such that only medallions 11 that are within the gaming station 100 can be detected by the sensors 15. In an example, the sensors 15 are positioned and adjusted to detect medallions 11 in each seating location separately such that the gaming station can distinguish between guests located in each different seating location. A seating location may be defined as an area two feet wide, zero to 5 feet from the floor, and from one foot behind the edge of the table (to cover a purse/bag at the users feet) to three feet from the edge of the table. The medallions 11 may be detected when in an accessory, pocket (front or back), or bag located within a seating location.

[00239] In some embodiments, the gaming station 100 also includes a canopy 105 extending above the seating 101 of the gaming station 100. In the examples of FIG 10, the canopy 105 is supported by two braces 107 and is formed of a semi-transparent material or a mesh material. The braces 107 support the canopy 105 and have integrated therein lighting (e.g., LED lighting) used to provide multi-colored lighting. The lighting may be controlled by a processor of the gaming station 100 to output lighting having an activation pattern and/or color pattern that is synchronized to a game being played on the gaming station 100. The braces 107 can further have integrated therein water misting spouts and/or scent/fragrance misting spouts. The misting spouts may be connected to a water supply valve or a reservoir (e.g., a scent reservoir) by piping extending through the braces 107 and into the seating 101 of the gaming station 100. The misting spouts connected to the water supply valve may be selectively controlled by a processor of the gaming station 100 to output water mist having an activation pattern that is synchronized to a game being played on the gaming station 100. The misting spouts connected to one or more scent reservoirs may be selectively controlled by the processor of the gaming station 100 to output scents (or mixtures of scents) having activation patterns and/or odors that are synchronized to the game being played on the gaming station 100. Separate misting spouts and piping may be provided in the braces 107 to separately and independently provide misting and scents. Additionally, different misting spouts and piping may be provided to emit different scents in the gaming station 100. [00240] The gaming station 100 typically includes additional sensory feedback modalities for users in addition to visual feedback provided through the display screens and lighting. For example, the gaming station 100 typically includes speakers for auditory feedback (e.g., speakers mounted to the central frame, to the seating 101, and to the braces 107), as well as haptic or touch feedback provided by actuators mounted to the user input devices 103 and the seating 101 among other locations.

[00241] The gaming station 100 can also include one or more external facing display screens 109 on which game play screens and images can be displayed in real time to allow other guests to watch a game in progress. In some examples, the external facing display screen 109 is touch-enabled and allows spectating guests to participate in game play and/or place wagers on game play and player outcomes. In such examples, the gaming station 100 can include one or more external-facing sensors 15 disposed so as to sense medallions 11 of guests located in front of the external facing display screen 109. The external -facing sensors 15 can be used to detect medallions 11 of the guests and allow those guests to log into the gaming station 100 via the external facing display screen 109 to allow the guests to participate in or place wagers on gameplay. The external facing display screens 109 can also be used by guests to register for or join a queue for game play, such that the guests can be invited to join game play in registration or queue order as seating locations open up in the gaming station 100.

[00242] Operation of the gaming station 100 may be controlled by a computing platform provided within the seating 101. The computing platform will typically include one or more processors (e.g., three or more processors in some embodiments), memory storing program instructions for game play, a power source (e.g., including an uninterruptible power source (UPS)), and connections to each of the displays and input devices 102, 103, and 109. The computing platform will also be connected via the communication network 19 to the servers 21 of the guest engagement system 10. The computing platform is further connected to actuators controlling the misting spouts, as well as to controllers controlling the lighting, sound, and haptic or touch feedback. The various feedback modalities may be individually controlled for each player seating position, such that different players can be provided with different sensory feedback (including misting, scent, sound, haptic, touch, light, and display) at any time under control of the computing platform. [00243] Additionally and/or alternatively, the above-identified features of the guest engagement system 10 can provide a seamless experience for the guest as the user travels through the facility. By way of example, a user can start a game on a selected display screen 109 of the gaming station 100 and continue the same game on a selected access panel 705 of their state room. For this purpose, the guest engagement system 10 relies on the access panels 705, interactive displays 17c, portals 17d, and the like that are located throughout the facility. In such examples, proximity of the user — based on, for example, location determination of the medallion 11 described herein — can trigger interface devices 17 to access profile information of the user associated with the detected medallion 11. Accordingly, the access panels 705, interactive displays 17c, portals 17d, and the like communicate wirelessly with the server 21 for retrieving profile information (including gaming preferences, status of current games being played, user biographical information, payment information, and so on) for the detected medallion 11 of the guest. Once the profile information is received, the interface devices 17 can display to the user a status of their last game played and ask the user if they would like to continue playing directly on the interface device 17.

[00244] In some embodiments, the game can be influenced by events and activity facilitated by all guests on a ship who are playing the game. For example, the gaming station 100 can support a raffle game that provides opportunities for users to enter the game on the access panels 705, interactive displays 17c, portals 17d, and the like. Each time the access panels 705, interactive displays 17c, and/or the portals 17d are accessed by a guest, an entry into the raffle game is created and a cumulative jackpot can be tallied. In other examples, interactions with the access panels 705, interactive displays 17c, portals 17d, and the like can count against those users who have already entered the raffle. The guest engagement system 10 thereby provides interaction with all users on the ship based on their seamless interaction with the system 10. [00245] FIGS. 11 and 12 provide functional block diagram illustrations of general purpose computer hardware platforms. FIG. 11 illustrates a network or host computer platform, as may typically be used to implement a server such as any of the servers 21 described herein. FIG. 12 depicts a computer with user interface elements, as may be used to implement a portal (e.g., 17d) or other type of work station or terminal device of the guest engagement system 10, although the computer of FIG. 12 may also act as a server if appropriately programmed. It is believed that those skilled in the art are familiar with the structure, programming and general operation of such computer equipment and as a result the drawings should be self-explanatory.

[00246] A server, for example, includes a data communication interface for packet data communication. The server also includes a central processing unit (CPU), in the form of one or more processors, for executing program instructions. The server platform typically includes an internal communication bus, program storage and data storage for various data files to be processed and/or communicated by the server, although the server often receives programming and data via network communications. The hardware elements, operating systems and programming languages of such servers are conventional in nature, and it is presumed that those skilled in the art are adequately familiar therewith. Of course, the server functions may be implemented in a distributed fashion on a number of similar platforms, to distribute the processing load.

[00247] Turning to FIG. 13, the guest engagement system 10 is shown as including at least one crew member 40. The crew member 40 can include any person that provides services or products to the guests 12. Exemplary crew members 40 can include the crew, staff members, employees, and hosts of the hotels and/or resorts. The crew member 40 is shown as operating a crew device 402. The crew device 402 can include a hand-held, mobile, and/or portable electronic device configured for wireless communication, optionally with mobile computing capabilities. Exemplary crew devices 402 can include two-way radio transceivers, walkie- talkies, mobile phones, smart phones, tables, and/or the like. The crew device 402 can be configured to communicate with the guest devices 11 and/or the sensors 15 via one or more selected wireless communication technologies. Additionally and/or alternatively, the crew device 402 can communicate with the system servers 21 via the communications network 19. Additionally and/or alternatively, the crew device 402 can, in a manner similar to the guest devices 11, communicate with the interface devices 17 (shown in FIG. 1) and/or the end devices 18 (shown in FIG. 9).

[00248] The crew device 402 is shown as being coupled with an antenna device 300 that is configured to emit signals supplied from the crew device 402. Additionally and/or alternatively, the antenna device 300 can receive a signal and transmit the signal to the crew device 402. Stated somewhat differently, regardless of whether the crew device 402 includes a built-in antenna and/or whether the built-in antenna can provide functionalities needed in the guest engagement system 10, the antenna device 300 can function as an interface between the crew device 402 and other wireless networks and/or devices to provide additional and/or alternative wireless communication capabilities of the crew device 402. Further, because the antenna device 300 can provide wireless communication functionalities independent of the built- in capabilities of the crew device 402, hardware and/or software of the antenna device 300 can be programmed and/or specifically developed even if the crew device 402 is commercially acquired and cannot be reprogrammed or customized. Advantageously, the crew, employees, and hosts of the hotels and resorts can fully utilize the guest engagement system 10 with the specifically customized antenna device 300.

[00249] The antenna device 300 is shown as being located in and/or on an optional accessory 400 for the crew device 402. The accessory 400 can be attached to, and/or be portable with, the crew device 402. In one embodiment, the accessory 400 can include a casing 420 (shown in FIG. 28) for at least partially enclosing the crew device 402. The accessory 400 can include additional elements that can provide selected functionalities. Hardware and/or software of the accessory 400 can be programmed and/or specifically developed even if the crew device 402 is commercially acquired and cannot be reprogrammed or customized. Advantageously, the accessory 400 can be easily used with the crew device and provide customized functions for fully utilizing the guest engagement system 10.

[00250] Turning to FIG. 14, the antenna device 300 is shown as including a first wireless communication antenna 320 and an optional second wireless communication antenna 340. The first and second wireless communication antennas 320, 340 can be configured to operate according to first and second communication standards, respectively. The first communication standard can be different from the second communication standard. In one embodiment, the first and second communication standards can include a Bluetooth communication standard and a near-field communication (NFC) communication standard, respectively. An exemplary Bluetooth communication standard can include a Bluetooth Low Energy (BLE) communication standard.

[00251] In some embodiments, the first wireless communication antenna 320 can include a directional antenna. Stated somewhat differently, the first wireless communication antenna 320 is shown as radiating power at the greatest gain, and/or with the least interference, in a direction 360 (or in z direction) compared with any other directions. For example, the first wireless communication antenna 320 can include a Yagi antenna, a log-periodic antenna, a corner reflector antenna, or a combination thereof. By using the first wireless communication antenna 320, the crew member 40 (shown in FIG. 13) can point the first wireless communication antenna 320 toward a selected guest 12, who carries a guest device 11, to obtain information associated with the selected guest 12 via BLE communication. Advantageously, even if the selected guest 12 is in a crowded environment and surrounded by other guests 12, the first wireless communication antenna 320 with the high level of directionality can capture information from the selected guest 12, such as identity, preferences and/or previous experiences. Interactions between the crew member 40 and the selected guest 12 can thus be personalized.

[00252] The directionality can be measured via a parameter such as directivity and/or peak directivity. A directivity can be a ratio of the power density of the antenna device 300 in a specific direction to the power density of a theoretical isotropic emitter of the same total power transmission level. A peak directivity can be a ratio of the power density of the antenna device 300 in the most concentrated direction (or at an end fire (EF) region) to the power density of the theoretical isotropic emitter of the same total power transmission level. Stated somewhat differently, the peak directivity of the antenna device 300 using the first communication standard can be measured in the direction 360.

[00253] The second wireless communication antenna 340 can increase a directionality and/or the peak directivity of the first wireless communication antenna 320. Stated somewhat differently, the second wireless communication antenna 340 can increase the gain of the first wireless communication antenna 320 in the direction 360. The second wireless communication antenna 340 can increase the directionality of the first wireless communication antenna 320 by having a specific shape, geometry, dimension, and/or electric properties to constructively interfere, in the direction 360, with the power emitted from the first wireless communication antenna 320. In one embodiment, the second wireless communication antenna 340 can be positioned at a selected distance and/or at a selected orientation relative to the first wireless communication antenna 320 to enhance power radiated from the first wireless communication antenna 320 in the direction 360. Advantageously, the second wireless communication antenna 340 can be used for more than one purpose, thus simplifying structure of the antenna device 300. [00254] Turning to FIG. 15, the first wireless communication antenna 320 is shown as including a Yagi antenna. The Yagi antenna can include a driven element 324, a reflector 322 and an optional director 326, each parallel to x direction and distributed along z direction. The driven element 324 can include a dipole that is driven and/or excited by an RF current from a transmitter (not shown) located on the accessory 400 (shown FIG. 13) and/or the crew device 402 (shown FIG. 13). The driven element 324 can be the source of the radio waves.

[00255] The reflector 322 and the director 326 can be parasitic elements and can include thin rod elements parallel to the x direction and of selected lengths, respectively. Waves from the reflector 322 and the director 326 can superpose and interfere to enhance radiation in the z direction, achieving a substantial increase in the gain of the first wireless communication antenna 320 compared to the dipole of the driven element 324.

[00256] The second wireless communication antenna 340 can include an antenna suitable for NFC communication. An exemplary second wireless communication antenna 340 can be configured for inductive coupling. In one embodiment, the second wireless communication antenna 340 can include at least one electromagnetic coil 342 (shown in FIG. 19). An exemplary electromagnetic coil 342 can wind within the x-y plane.

[00257] The second wireless communication antenna 340 can function as a director for the first wireless communication antenna 320 and increase the gain of the first wireless communication antenna 320 in the direction 360. Stated somewhat differently, the second wireless communication antenna 340 can re-radiate waves that are received from the first wireless communication antenna 320 in the direction 360. The second wireless communication antenna 340 can be positioned at a selected distance D from the most proximal director 326, such that the re-radiated waves are in phase with the received waves in the direction 360, resulting in constructive interference and increasing the gain of the first wireless communication antenna 320. The selected distance D can depend on a frequency of the waves of the first wireless communication antenna 320. An exemplary distance D can be 2 millimeters at a frequency of 2.4 GHz and for a Yagi antenna (as the first wireless communication antenna 320). In an illustrative example, the Yagi antenna can include a Yagi-Uda microstrip antenna on FR(Flame Retardant)-4 material with relative permittivity (Er) of 4.

[00258] Turning to FIG. 16, the first and second wireless communication antennas 320, 340 can each be disposed on first and second printed circuit boards (PCBs) 328, 348, respectively. Stated somewhat differently, the first wireless communication antenna 320 can be integrated with the first PCB 328 to form a PCB assembly. Similarly, the second wireless communication antenna 340 can be integrated with the second PCB 348 to form another PCB assembly. The first PCB 328 is shown as being parallel to the x-z plane. The second PCB 348 is shown as being parallel to the x-y plane and orthogonal to the first PCB 328.

[00259] Although the first and second wireless communication antennas 320, 340 and the first and second PCBs 328, 348 are shown with the specific spatial orientations for illustrative purposes only, the first and second wireless communication antennas 320, 340 and the first and second PCBs 328, 348 can be oriented in other manners suitable for implementing the functions as set forth above, without limitation. Although the first PCB 328 is shown as being coupled with the second PCB 348 at an end region of the second PCB 348 along the y direction for illustrative purposes only, the first PCB 328 can be coupled with the second PCB 348 at any other suitable regions of the second PCB 348, without limitation. For example, the first PCB 328 can be coupled with the second PCB 348 at a center region of the second PCB 348, that is at a middle region along the height H of the second wireless communication antenna 340.

[00260] In one embodiment, the first and second PCBs 328, 348 can be arranged in parallel such that the first and second wireless communication antennas 320, 340 are both aligned with the x-z plane. Stated somewhat differently, both of the first and second wireless communication antennas 320, 340 can be located at, and/or parallel to, a bottom of the crew device 402 (shown in FIG. 31).

[00261] However, the second PCB 348 shown in FIG. 16 as being orthogonal to the first PCB 328 can advantageously be easier to use because, when scanning a device (such as the guest device) in proximity, the crew member 40 (shown in FIG. 13) or the guest 12 (shown in FIG. 13) can more easily identify the location of the second wireless communication antenna 340 and do not need to search for the second wireless communication antenna 340 over a large bottom area of the crew device 402. Additionally and/or alternatively, radiation of the second wireless communication antenna 340 can be less intrusive to the radiation of the first wireless communication antenna 320.

[00262] For the second wireless communication antennas 340 to both achieve a sufficient gain for the second communication standard and improve a directionality of the first wireless communication antennas 320, one or both of the first and second wireless communication antennas 320, 340 may need to be configured in a selected manner. In one embodiment, the second wireless communication antenna 340 may need to be configured to achieve a gain that is less than a maximum possible gain for the second communication standard (for example, the NFC communication standard). The maximum possible gain is a gain that can be achieved when the second wireless communication antenna 340 is individually optimized under the second communication standard without taking into account of the first wireless communication antenna 320. Stated somewhat differently, a sacrifice in the gain of the second wireless communication antennas 340 may be needed for the second wireless communication antenna 340 to not compromise, or to even improve, the directionality of the first wireless communication antenna 320.

[00263] In one embodiment, the second wireless communication antenna 340 can have a width of W (shown in FIG. 15 and 19) and a height of H (also shown in FIG. 19). Stated somewhat differently, the second wireless communication antenna 340 can span across an area of W x H. A maximized area is desired for individually improving the gain of the second wireless communication antenna 340. Stated somewhat differently, maximizing W and H is desired typically. Further, a W:H ratio of 2: 1 is typically used for achieving the maximum possible gain. [00264] However, the above W:H ratio may need to be changed for making the antenna device 300 for the following reasons. With a given W, a greater H can result in a greater extension of the second wireless communication antenna 340 beyond the x-z plane that is parallel to the plane of the first wireless communication antenna 320. The greater extension can result in greater scattering of radiation of the first wireless communication antennas 320 beyond the x-z plane, thus reducing the directionality of the first wireless communication antennas 320. The W:H ratio may therefore be reduced. In one example, when the first wireless communication antennas 320 includes a a Yagi-Uda microstrip antenna on FR(Flame Retardant)-4 material with relative permittivity (Er) of 4, a W:H ratio of 3:1 can be found for the second wireless communication antennas 340 to both achieve a sufficient gain for the second communication standard and improve a directionality of the first wireless communication antennas 320. Optimization of configuration of the first and/or second wireless communication antennas 320, 340 can be performed by using any suitable antenna design and simulation software tools. In some embodiments, the Yagi antenna can be shaped based on wavelength and coupling factors. The height and width of the second wireless communication antenna 340 acting as the director 326 (shown in FIG. 15) can be optimized based on a parasitic load on the first and/or second wireless communication antennas 320, 340. In some embodiments, a shorter second wireless communication antenna 340 (that is, a small H) can better resemble a typical director element of the Yagi antenna, and can have a better performance as a director 326. Such a result can be expected based on theoretical calculation and/or based on simulation.

[00265] FIGS. 17 and 18 show top and bottom sides of an exemplary first wireless communication antenna 320 on the first PCB 328, respectively. The top and bottom sides are in and against y direction, respectively. The first wireless communication antenna 320 is shown as including three directors 326 distributed in parallel, including directors 326A-326C. The driven element 324 is shown as including a folded dipole.

[00266] FIGS. 19 and 20 show top and bottom sides of an exemplary second wireless communication antenna 340 on the second PCB 348, respectively. The second wireless communication antenna 340 is shown as including the electromagnetic coil 342 wound in parallel to the second PCB 348.

[00267] Although the top side of the second wireless communication antenna 340 is shown as facing in the z direction for illustrative purposes only, the top side of the second wireless communication antenna 340 can be oriented against the z direction, at a selected angle relative to the z direction, and/or in other manners suitable for implementing the functions as set forth above, without limitation.

[00268] Turning to FIG. 21, the antenna device 300 is shown as including an antenna carrier 380 that at least partially encloses the first and second wireless communication antennas 320, 340. The antenna carrier 380 can be made of any suitable materials and can provide pre defined slots for holding the first and second wireless communication antennas 320, 340. The antenna carrier 380 is shown as having an L shape but can have any other suitable shapes, sizes and/or dimensions.

[00269] Turning to FIG. 22, the antenna carrier 380 is viewed from a view angle different from FIG. 21. The antenna carrier 380 is shown as covering at least one side of the first and second wireless communication antennas 320, 340. In one embodiment, the antenna carrier 380 can cover all surfaces of the first and second wireless communication antennas 320, 340 but define optional openings to a selected area of a surface of the first and/or second wireless communication antennas 320, 340.

[00270] Turning to FIG. 23, an exploded diagram of the antenna device 300 is shown. The antenna carrier 380 is shown as including top and bottom covers 380A, 380B that enclose the first and second wireless communication antennas 320, 340 therebetween. The top and bottom covers 380A, 380B can be made of any suitable materials and can provide pre-defmed slots for holding the first and second wireless communication antennas 320, 340.

[00271] FIG. 24A is a three-dimensional (3D) radiation pattern of an exemplary first wireless communication antennas 320 without the second wireless communication antenna 340. The gain of the first wireless communication antenna 320 reaches a maximum at an end region thereof along the z direction. FIG. 24B is a plot showing a realized gain as a function of frequency for the exemplary first wireless communication antennas 320.

[00272] FIG. 25A is a 3D radiation pattern of the antenna device 300 including the first and second wireless communication antennas 320, 340 and the antenna carrier 380. The radiation pattern indicates that a gain of the antenna device 300 reaches a maximum at an end region thereof along the z direction. Further, the gain reaches a minimum near a middle region of the antenna device 300, the minimum being more visible than a minimum of the gain in FIG. 24A. Thus, the peak directivity of the first wireless communication antenna 320 is improved via the combination with the second wireless communication antenna 340. The antenna device 300 as shown in FIG. 25 can be achieved via optimization to achieve resonance center frequency (that is, resonance of the desired frequency of, for example, 2.45 GHz) in a region enclosed between top and bottom covers 380A, 380B (shown in FIG. 23). FIG. 25B is a plot showing realized gain as a function of frequency.

[00273] FIG. 26A is a 3D radiation pattern of the antenna device 300 including the first wireless communication antenna 320, the second wireless communication antenna 340 and the antenna carrier 380 after a selected optimization process. Stated somewhat differently, the antenna device 300 shown in FIG. 26A is achieved by further optimization via tuning, in comparison with the antenna device 300 shown in FIG. 25 A. The radiation pattern indicates that a gain of the antenna device 300 reaches a maximum at an end region thereof along the z direction and is greater in comparison with the gain of the radiation pattern in FIG. 24A. Further, the gain reaches a minimum near a middle region of the antenna device 300, the minimum being more visible than a minimum of the gain in FIG. 24A. Thus, the peak directivity of the first wireless communication antenna 320 is improved via the combination with the second wireless communication antenna 340. FIG. 26B is a plot showing realized gain as a function of frequency. [00274] Turning to FIG. 27, an exemplary accessory 400 is shown as including the casing 420 and the antenna device 300 attached to the casing 420. The casing 420 can at least partially enclose the crew device 402 (shown in FIG. 13). The casing 420 is shown as having a planar shape parallel to the x-z plane. When the crew device 402 is in the casing 420, the side of the crew device 402 of the greatest surface area can be parallel to the x-z plane.

[00275] The antenna device 300 can optionally be movably coupled to the casing 420 such that the antenna device can move relative to the casing 420, and/or the crew device 402, along a direction 362. For example, the moving can include a sliding motion. Stated somewhat differently, the antenna device 300 can be slidably coupled to the casing 420 such that the antenna device 300 can slide relative to the casing 420, and/or the crew device 402. Because an electromagnetic field generated in the crew device 402 and/or the casing 420 can change a radiation pattern of the antenna device 300, sliding the antenna device 300 can adjust the radiation pattern of the antenna device 300. Advantageously, directionality of the radiation pattern of the antenna device 300 can be changed in a simple manner.

[00276] Turning to FIG. 28, the accessory 400 is shown as including one or more additional hardware components as desired including, a battery 440. The battery 440 can include a power source for powering the hardware components of the accessory 400 and/or powering the crew device 402 (shown in FIG. 13). An exemplary battery 440 can include a lead-acid battery, a lithium air battery, a lithium-ion battery, a nickel -cadmium battery, a nickel-metal hydrogen battery, or a combination thereof. Optionally, the battery 440 can be rechargeable.

[00277] Additionally and/or alternatively, the accessory 400 can include an NFC reader 460. The NFC reader 460 can optionally be integrated with an NFC writer (not shown). The NFC reader 460 can read information stored on NFC devices, such as NFC tags, embedded in the guest devices 11 (shown in FIG. 13).

[00278] Additionally and/or alternatively, the accessory 400 can include a communication interface 480 for communicating with the crew device 402. In one embodiment, the communication interface 480 can include a connector and/or port for connecting to a transceiver (not shown) on the crew device 402 such that the transceiver can receive and/or transmit data via the antenna device 300. An exemplary communication interface 480 can include universal serial bus (USB), digital visual interface (DVI), display port, serial ATA (SATA), IEEE 1394 interface (also known as FireWire), serial, video graphics array (VGA), super video graphics array (SVGA), small computer system interface (SCSI), high-definition multimedia interface (HDMI), audio ports, and/or proprietary input/output interfaces). In one embodiment, the communication interface 480 can include a USB connector, such as a USB-C connector.

[00279] Additionally and/or alternatively, the accessory 400 can include one or more processors 410. The processors 410 can function as a controller for directing some or all operations of the accessory 400, such that the computation functions of the accessory 400 can be customized without being limited to functions of the crew device 402. Without limitation, each processor 410 can include one or more general purpose microprocessors (for example, single or multi-core processors), application-specific integrated circuits, application-specific instruction- set processors, graphics processing units, physics processing units, digital signal processing units, coprocessors, network processing units, audio processing units, encryption processing units, and the like. The processors 410 can be configured to perform any of the methods described herein, including but not limited to, a variety of operations relating to turning on and/or off one or both of the first and second wireless communication antennas 320, 340. Additionally and/or alternatively, the processors 410 can be configured to control power supply from the battery 440, communication with the crew device 402, or a combination thereof.

[00280] Additionally and/or alternatively, the accessory 400 can include an indicator device 430 for indicating a status of a selected operation to an operator, by visual, audio, mechanical, and/or other techniques. An exemplary indicator device 430 can include one or more light emitting devices. In one embodiment, when the NFC reader 460 receives data via the second wireless communication antenna 340, the light emitting device can turn on and/or change intensity. Additionally and/or alternatively, the accessory 400 can include a memory 450 (for example, a random access memory (RAM), static RAM, dynamic RAM, read-only memory (ROM), programmable ROM, erasable programmable ROM, electrically erasable programmable ROM, flash memory, secure digital (SD) card, etc.).

[00281] Additionally, and/or alternatively, the accessory 400 can include a communication module (not shown) for exchanging data and/or instruction between the accessory 400 and another computer system (not shown) using any wired and/or wireless communication methods. Exemplary communication methods include, for example, radio, Wireless Fidelity (Wi-Fi), cellular, satellite, broadcasting, or a combination thereof. [00282] The hardware components of the accessory 400 can be configured to communicate, for example, using hardware connectors and buses and/or in a wireless manner. Some of the hardware components of the accessory 400 can be located on, and/or distributed among, the casing 420 and the antenna device 300.

[00283] Turning to FIG. 29, an exploded diagram of the accessory 400 is shown with the crew device 402. The casing 420 is shown as including a bottom assembly 420A, a top assembly 420B and an elastic skin 420C. The antenna device 300 can be attached to an antenna cover 382 for protection. The accessory 400 can include a PCB assembly 470 that integrates selected components thereon including, for example, the NFC reader 460 (shown in FIG. 28), the communication interface 480 (shown in FIG. 28), the processors 410 (shown in FIG. 28), and/or the memory 450 (shown in FIG. 28).

[00284] Turning to FIG. 30, the antenna device 300 is shown as being in a retreat position. In the retreat position, the first wireless communication antenna 320 can stack with the PCB assembly 470 (shown in FIG. 29), the casing 420 and/or the crew device 402. Because circuits (not shown) in the PCB assembly 470, the casing 420 and/or the crew device 402 can emit the electromagnetic field that can change the radiation pattern of the antenna device 300, the first wireless communication antenna 320 can be detuned (or loaded) by the electromagnetic field at the resonant frequency and thus become omni-directional (or less directional). Stated somewhat differently, the first wireless communication antenna 320 can have more equal gain in all directions. Advantageously, the antenna device 300 can sense proximity of the guest devices 11 (shown in FIG. 13) in any directions when the crew member 40 (shown in FIG. 13) is waiting for instruction or commands from the guests 12 (shown in FIG. 13).

[00285] Turning to FIG. 31, the antenna device 300 is shown as being in a deployment position. In the deployment position, the first wireless communication antenna 320 can be located distally from the PCB assembly 470 (shown in FIG. 29), the casing 420 and/or the crew device 402 by being moved over a selected distance from the retreat position. Because the circuits (not shown) in the PCB assembly 470 (shown in FIG. 29), the casing 420 and/or the crew device 402 can become more distal from the first wireless communication antenna 320, the electromagnetic field from the circuits can become less effective in detuning the first wireless communication antenna 320. The first wireless communication antenna 320 can thus become more directional. Stated somewhat differently, the first wireless communication antenna 320 can have a greater gain in the direction 360. Thus, instead of installing a relatively omni-directional antenna and a directional antenna and switching therebetween, the first wireless communication antenna 320 can be relatively omni-directional or directional by changing positions. Advantageously, structure and operation of the antenna device 300 can be simplified. The antenna device 300 can be connected with the accessory 400 and/or the crew device 402 via suitably routed cables (such as a coaxial cable) such that the cable connection can be maintained during transition between the retreat and deployment positions. In contrast to the antenna device 300, conventional antennas do not exhibit directional radiation patterns in a form factor of a handheld electronic device. Especially, conventional antennas exhibit even less directional radiation patterns in a handheld electronic device with integrated NFC into the antenna structure. An additionally and/or alternative unique aspect of the antenna 300 is the purposeful altering of the radiation pattern from directional to isotropic based upon deployment of the antenna 300. [00286] The antenna device 300 can move into the deployment position along the direction 360. Advantageously, operation of the antenna device 300 can be simple and intuitive because the operator can slide the antenna device 300 in the direction pointing toward the selected guest 12. However, the transition of the antenna device 300 between the retreat and deployment positions are shown in FIGS. 25 and 26 for illustrative purposes only. The antenna device 300 can move into the deployment position in another direction that is different from the direction 360. Stated somewhat differently, the direction of the movement of the antenna device 300 can be different from the direction of the first wireless communication antenna 320, without limitation.

[00287] FIG. 32 is a 3D radiation pattern of the antenna device 300 in the retreat position. The radiation pattern is shown as being similar in all directions. FIG. 33 is a 3D radiation pattern of the antenna device 300 in the deployment position. The radiation pattern indicates that a peak directivity of the antenna device 300 is obtained at an end region (or EF region) thereof along the z direction and is greater in comparison with the peak directivity of the radiation pattern in FIG. 33. Thus, the peak directivity of the antenna device 300 is improved in the deployment position. [00288] Turning to FIG. 34, an exemplary method 490 for using the antenna device 300 is shown. The antenna device 300 can be optionally disposed, at 491, in the retreat position. In the retreat position, the antenna device 300 can be proximal to the crew device 402. Stated somewhat differently, the antenna device 300 can be proximal to the casing 420 that holds the crew device 402. Accordingly, the first wireless communication antenna 320 (shown in FIG. 30) can be more omni-directional. In some embodiments, the antenna device 300 can be in the retreat position when being carried with the crew device 402 by a crew member and thus does not need to be disposed at the retreat position via any action from the crew member.

[00289] The antenna device 300 can be moved, at 492, distally from the accessory 400 into the deployment position. The antenna device 300 can be directional in the deployment position for establishing wireless communication between the crew device 402 and the guest device 11 (shown in FIG. 13) that the antenna device 300 points toward. For example, the antenna device 300 can be moved toward the guest device 11 to be in the deployment position. Stated somewhat differently, the direction 360 (shown in FIG. 31) can be aligned with a direction pointing from the antenna device 300 to the guest device 11. In some embodiments, the first wireless communication antenna 320 can be directional such that the crew device 402 can establish wireless communicate, via BLE communication, with the guest device 11.

[00290] Turning to FIG. 35, a detail drawing of the antenna device 300 in the retreat position is shown. The antenna device 300 is shown as having the L shape, with the first wireless communication antenna 320 stacked with the crew device 402 and the second wireless communication antenna 340 contacting an edge of the casing 420.

[00291] Turning to FIG. 36, a detail drawing of the antenna device 300 in the deployment position is shown. The antenna device 300 can be moved distally from the crew device 402. The antenna carrier 380 can be pulled and/or pushed manually by an operator to move the first and second wireless communication antennas 320, 340 as a whole. Additionally and/or alternatively, transition of the antenna device 300 between retreat and deployment positions can be implemented automatically and/or robotically.

[00292] FIGS. 37 and 38 show the antenna device 300 in the retreat and deployment positions, respectively. In contrast with the antenna device 300 shown in FIGS. 25-26, the antenna device 300 includes the first wireless communication antenna 320 without the second wireless communication antenna 340 (shown in FIGS. 30-31). Accordingly, the first wireless communication antenna 320 can be configured for BLE communication and an NFC antenna in the crew device 402 can be used for NFC communication. In this case, the first wireless communication antenna 320 can have at least one director 326 (shown in FIG. 15) because the second wireless communication antenna 340 is not available for achieving constructive interference needed for directional radiation.

[00293] FIGS. 39 and 40 show detail drawings of the antenna device 300 in the retreat and deployment positions, respectively. FIGS. 41 and 42 show detail drawings of the accessory 400, without the crew device 402, with the antenna device 300 in the retreat and deployment positions, respectively.

[00315] In some embodiments of the disclosed accessory, the antenna device is more directional in the deployment position than in the retreat position for operating using the first communication standard.

[00326] In some embodiments of the disclosed method, the method further includes aligning the selected direction with a direction pointing from the antenna device to a distal electronic device for the mobile electronic device to communicate with the distal electronic device using the first communication standard.

[00327] Additionally and/or alternatively, the above-identified features of the guest engagement system 10 can provide an advanced security platform or the like. For example, in some embodiments, the guest engagement system 10 can be used to determine location-based information of each medallion 11 and maintain descriptive data on each of the several guests 12, each of whom is associated with a respective medallion 11.

[00328] Turning to FIG. 43, an exemplary block diagram showing an alternative embodiment of the guest engagement system 10 is shown. As previously described, the guest engagement system 10 is configured to communicate wirelessly with the guest devices 11, such as the medallions worn or carried by the guests 12 (shown, for example, in FIG. 1 A), which each uniquely identify an associated guest and are configured for secure communication with the guest engagement system 10. In some embodiments, each medallion 11 can be labeled to identify the associated guest 12. For example, the name of the guest 12 can be physically engraved onto the medallion 11 and/or electronically encoded on local storage ( e.g ., the memory 601 of the medallion 11) of the device. Additionally and/or alternatively, this relationship or association between guests 12 and medallions 11 can be maintained at the server 21, such as described herein. [00329] The sensor network 13 of sensors 15 are mounted throughout the facility and configured to communicate wirelessly with guests’ medallions 11. A selected sensor 15 of the network 13 may be used for sensing a guest’s location (or proximity to the sensor 15), for example by detecting beacon signals or other signals emitted by the medallion 11. The sensor 15 can also engage in two-way communication with the medallion 11 to transmit information to and receive information from the medallion 11. In this way, and as described in further detail above (see, e.g., the discussion of FIG. 9), the services provided through the end devices can include location services (including location-sensing of medallions based on the end devices sensing medallions’ beacon signals, and reporting of sensed medallions and locations to a system server 21), and causing medallions to trigger security features among other services. For example, the server 21 can maintain a log of known locations for each guest 12, such as for purposes of contact tracing.

[00330] However, when medallions 11 are outside of the range of the sensor network 13, the guest engagement system 10 can advantageously rely on the communication and storage of each medallion 11 to maintain an accurate location of each medallion 11. For example, the guest devices/medallions 11 are configured to communicate using at least one wireless communication technology/protocol and, preferably, are configured to communicate using two or more distinct wireless communication technologies/protocols. For example, a medallion 11 can be configured to communicate according to both near field communication (NFC) standards and Bluetooth low energy (BLE) standards, though the medallion 11 may generally operate using only one of the standards at any given time in order to reduce energy expenditure. In some embodiments, a first medallion 11 can communication with one or more second medallions 11 to communicate location-based information, such as shown in FIGs. 44A-D.

[00331] Additionally and/or alternatively, a first medallion 11 can communication with one or more second medallions 11 to communicate a unique identifier and/or a signal strength such that proximity at the time the signal was captured can be determined as described herein. As described above, location information can be inferred when medallions 11 are detected by one or more of the sensors 15 of the sensor network 13. If the medallion 11 is outside of the sensor network 13, the guest engagement system 10 can advantageously determine “missing” location information until the medallion 11 is back within range of the sensor network 13. In some embodiments, this “missing” location information is determined by comparing timestamps and proximity (such as described below) between medallions 11 that were sensed by the sensor network 13 and those medallions 11 that only registered proximity to another medallion 11. [00332] Turning to FIG. 44A, the medallion 11 can be configured to alternate between a listening mode and a broadcasting mode during a single predetermined time unit 90. The predetermined time unit 90 is defined by the length of a cycle of a listening window 91 during the listening mode and one or more broadcasting windows 92 during the broadcasting mode. As shown in the example of FIG. 44A, the medallion 11 is defined by a time unit of 10,000ms. The listening window (or listen duration) 91 is the duration per time unit 90 that the medallion 11 listens. In this example, the medallion 11 listens for 80ms. In another exemplary embodiment, the medallion 11 can listen for 0.16 seconds, such as shown in FIG. 44B. Similarly, the broadcast window (or broadcast interval) 92 is the interval of broadcast windows ( e.g ., 70ms in FIGs. 44A- B).

[00333] Stated in another way, the medallion 11 operates on time units. A selected medallion 11 can listen for other medallions that are broadcasting at a predefined signal strength. For example, the predefined signal strength can be measured using the Received Signal Strength Indicator (RSSI) of the medallion 11. The RSSI is an estimated measure of power level that an RF client device receives from a wireless device. By way of example, the predefined signal strength (or signal strength cutoff) can be set to -63 such that the medallion 11 will only listen for other devices that are broadcasting above an RSSI of -63. In other words, selected medallions that are broadcasting a signal during the broadcasting window 92 are picked up by those medallions 11 that are in their listening window 91 cycle.

[00334] In some embodiments, a predetermined number of detections is required before contact is registered. In the example shown in FIG. 44A, two time unit detections are needed to establish a “contact.” As used herein, a “contact” can include a contact session, a network session, or a session. Therefore, over at least a period of 20 seconds, a medallion 11 would need to detect a broadcast signal having an RSSI of -63 for a selected medallion during the listening window 91 at least twice. Similarly, a predetermined number of time units required to break the contact can be defined. For example, if a selected medallion 11 is not detected for a period of 2- 15 time units (20-150 seconds), any existing contact with the selected medallion 11 is broken. [00335] Although specific examples are provided, the duration of the predetermined time unit 90, the listening window 91, the broadcasting window 92, the predefined signal strength, the number of detections required for a contact, and the number of non-detected time units to break contact are configurable as desired. In some embodiments, these parameters can be configured or tuned to match a desired approximation of distance. This desired approximation of distance often depends on several factors ( e.g ., room size, physical obstructions, competing wireless signals, competing device signals, distance, technical settings, and so on). In other words, the parameters can be tuned to account for these factors much like a piano is tuned different in a large proscenium versus a small controlled studio environment. Accordingly, the RSSI of -63 is described above as an exemplary cutoff for a selected medallion only. Therefore, it should be appreciated that in some embodiments, two consecutive reads during a 20 second period of an RSSI between -0 to -65 can be used for a range of Oft to 2M. For some locations (e.g., mainly outdoor locations, but including some interior locations), a signal strength of at least -65 is required. In these conditions, where/how the medallion 11 is worn (e.g, on the chest, wrist, stomach, in clothes, outside of clothes), the size of the user (e.g, large, small, short, tall), and physical barriers of the environment can change the behavior of the signal strength of the device 11. With reference to FIG. 46b, an exemplary signal strength that is read as a function of distance is shown. An exemplary contact between two medallions 11 is shown in FIG. 44C. Another exemplary contact between two medallions 11 is illustrated in FIG. 44D. [00336] Each medallion 11 can maintain information about medallions that have been in contact and/or have broken contact during the predetermined time units. For example, the memory 601 stores a unique identifier used by the guest engagement system 10 to uniquely identify each medallion. The memory 610 can also store encryption and decryption keys, and encrypted data. For example, in one example, the memory stores both a public identifier for the medallion 11 that uniquely identifies the medallion and is broadcast during the broadcasting window 92 emitted by the medallion, and a private identifier that also uniquely identifies the medallion, is stored in an encrypted format in the memory, and is used to securely authenticate the medallion ( e.g ., for use in payments and for unlocking doors). Additionally and/or alternatively, the memory 601 can maintain a relational database of other public identifiers for other medallions 11 that have been in contact and the associated user. This information can be provided to the server 21 for processing, for example, when the medallion 11 is within broadcasting range of the sensor network 13. Advantageously, each medallion 11 can maintain an accurate history of other medallions 11 within broadcasting range to complete a location history for any medallions independent of whether they are within broadcasting range of the sensor network 13. Together, the medallions 11 expand the range of signal processing of the sensor network 13 for the guest engagement system 10.

[00337] FIG. 45 illustrates an exemplary method for determining location-based information using the medallions 11. As described, the medallion 11 can be configured to alternate between a listening mode and a broadcasting mode during a single predetermined time unit 90. During the broadcasting mode, the medallion 11 can broadcast its unique identifier and/or a signal strength at a predetermined interval (at step 4501). During the listening mode (step 4502), the medallion 11 can listen for other medallions that are broadcasting at a predefined signal strength. For example, the predefined signal strength can be measured using the RSSI of the medallion 11. Multiple samples are taken over time to generate a confidence index of the start of a contact session.

[00338] In some embodiments, a falloff duration can be used to keep a contact session held. The falloff duration is particularly advantageous in those situations where a selected medallion 11 fails to rebroadcast at an expected signal strength for a specific duration after an initial connection has occurred. In other words, it is possible that the selected medallion 11 is physically close to a second medallion 11 after an initial connection has occurred; however, the selected medallion 11 may not rebroadcast at the expected signal strength for a sufficient duration following the initial connection. Therefore, a falloff duration can be used to prevent an immediate (and inaccurate) break in the contact session established between the selected medallion 11 and the second medallion 11. Accordingly, the falloff duration can define a predetermined n number of listening periods wherein a medallion 11 is not sensed after an initial contact has been established that must occur before a disconnect or break in contact session is determined. By way of example, the falloff duration is used to capture as many possible contacts while minimizing false positives, such as shown in FIG. 46a. As shown in FIG. 46a, each dot represents users of the medallions 11, their actual distance from one or more receivers ( e.g ., sensors 15, the sensor network 13, or other medallions 11), and a statistical average of the signal strength read by a selected individual for a few seconds.

[00339] Each contact session can be stored with one or more time stamps, for example, indicating a session start time and a session end time with an associated signal strength. Once the medallion 11 is within range of the sensor network 13, the medallion 11 offloads data to the central server 21 (at step 4503). In some embodiments, stored data on the medallion 11 can be offloaded, for example, when a certain capacity (e.g., 75% storage) is reached, when a specified time period (e.g, every 6 hours) occurs, and/or when the central server 21 forces a fetch from the medallion 11. The server, such as an appliance 21 (FIG. 43), can then post-process data received from the medallion 11 (at step 4504). Additionally and/or alternatively, a report of this information can be generated (not shown).

[00340] Returning to FIG. 43, an appliance 21a can serve as a central management device to aggregate data from the medallions 11 for communication to a cloud-based web server 21b. As shown, the appliance 21a can reside in a data center and broker communications from one or more collectors 23. However, the appliance 21a can be disposed at the facility or a remote location as desired. The collectors 23 can be wired and/or wireless.

[00341] In a preferred embodiment, the appliance 21a smooths out gaps in time, bilaterally correlates missing location intervals between two medallions 11, sorts/organizes by time intervals and session intervals, and augments with the location data when used in combination with location sensors. For example, the appliance 21a can increase the fidelity of possible inclusive contacts for each medallion 11. In some embodiments, the appliance 21a combines and merges connection sessions with up to a predetermined x minute gap into a single combined session. Additionally, the appliance 21a can compare connection sessions of two medallions 11 to combine/merge missing sessions. For example, the appliance 21a can bilaterally correlate at least two (and, often, up to hundreds) uploaded data sets representing network sessions/contacts established. The bilateral correlation process identifies a selected time to be compared. At this selected time, the appliance 21a compares time stamps that a second medallion 11 has come within range of a first medallion 11. In this way, this missing contact can be filled in for the first medallion much like a third-person account of where the first medallion 11 was during some periods that may be missing for the first medallionl 1. The appliance 21a can also consolidate sessions, such as by excluding any connection session under a predetermined y minutes or exclude any connection session before a predetermined number of days.

[00342] Additionally, the appliance 21a can smooth two or more contact sessions. For example, a first medallion 11 can have a thirty-second contact session with a second medallion 11, followed by a forty-five-second period where no contact was established/maintained with any other medallion, followed by another thirty-second contact session. The appliance 21a can optionally smooth these three periods by linking the first thirty-second contact session with the second thirty-second contact session and averaging over the total time. Similarly, the appliance 21a can implement parameterized smoothing, which is based on a predefined duration (parameter) that a window of no contacts can be joined by two other windows where contacts were established. In some embodiments, feedback or machine learning methods can be used a best guess to maximize the smoothing parameters. Additionally and/or alternatively, other post processing can be used to best approximate distance such as, for example, averaging intervals and stitching events, analyzing known samples for feedback to automatically determine stitching ( e.g ., Tertiary sensors or multiple medallions 11).

[00343] Turning to FIG. 47, an alternative embodiment of the guest device 11 is shown as including the microprocessor (or processor) 603, at least one wireless communication antenna 512 and at least one device health sensor 530. The wireless communication antenna 512 and the device health sensor 530 can be in communication with the processor 603. In various embodiments, the wireless communication antenna 512 can include the BLE antenna 513 (shown in FIG. 5B), the NFC antenna 515 (shown in FIG. 5B), or a combination thereof.

[00344] The device health sensor 530 can be configured to detect at least one health function of a user 52 (shown in FIG. 63) wearing the guest device 11. An exemplary user 52 can include the guest 12 (shown in FIG. 1 A) and/or the crew member 40 (shown in FIG. 13). In one embodiment, each of the users 52 can be a guest 12. The health function can include any body function that can indicate a status of health of the user 52. A measurement of the health function that indicates an anomaly can be a symptom of an illness, injury, and/or medical condition. Exemplary health functions can include, but are not limited to, body temperature, skin temperature, blood pressure, pulse (or heart rate), and breathing rate (or respiratory rate), skin, pupils, pain, menstrual cycle, oxygen saturation (or Sp02, for example, measured by pulse oximetry), blood glucose level, shortness of breath, gait speed, coughing, sneezing, and/or the like. The device health sensor 530 can include any sensor, measurement device, and/or sensing device, that measures at least one health function. An exemplary device health sensor 530 can include a temperature sensor, a pulse oximeter, heart rate monitor, breathing rate monitor, cough detector (for example, accelerometer and/or audio signal sensor), electrocardiogram (ECG or EKG) sensor, or a combination thereof.

[00345] Turning to FIG. 48, the guest device 11 is shown as including a body 540 having the front (or upper) and rear (or back, or lower) surfaces 11a, lib. The body 540 is shown as defining a cavity 542 therein. The microprocessor 603, the antenna wireless communication antenna 512 and the device health sensor 530 are shown as being disposed in the cavity.

[00346] In one embodiment, the health function can include a body temperature of the user 52 (shown in FIG. 63). The device health sensor 530 can include a temperature sensor. When the user 52 wears the guest device 11, the front and rear surfaces 11a, lib can be distal from and proximal to a body surface of the user 52, respectively. The device health sensor 530 is shown as being proximal to the rear surface lib. Advantageously, the device health sensor 530 can detect the body temperature of the user 52 accurately.

[00347] Although the device health sensor 530 is shown as being disposed in the body 540 for illustrative purposes only, the device health sensor 530 can be partially disposed in the body 540, and/or disposed outside the body 540, without limitation.

[00348] Turning to FIG. 49, the guest device 11 is shown as including a bottom assembly 546 defining the rear surface 1 lb. In various embodiments, the bottom assembly 546 can be at least partially made of a thermally conductive material. In one embodiment, the rear surface 1 lb can be at least partially thermally conductive. Advantageously, when the rear surface 1 lb is in contact with, and/or proximal to, the body surface of the user 52 (shown in FIG. 63), a temperature of the rear surface 1 lb can be equalized with the temperature of the body surface in a prompt manner.

[00349] Turning to FIG. 50, the bottom assembly 546 is shown as including the bottom cap 503. The bottom cap 503 can define a shape and/or size of the rear surface l ib. In one embodiment, the bottom cap 503 can be as shown in FIGS. 5B-5E. In one embodiment, the bottom cap 503 can be made of a thermally conductive material. For example, the bottom cap 503 can be at least partially made of a thermally conductive plastic material. Exemplary plastic thermally conductive plastic material can include a conductive polymer, a polymer with thermally conductive fillers (for example, metal, graphite, nanofillers, carbon black). Advantageously, by only modifying material of the bottom cap 503, the shape and size of the bottom cap 503 can be unchanged to incorporate the device health sensor 530 into the guest device 11.

[00350] Turning to FIG. 51, the bottom assembly 546 is shown as including the bottom cap 503 and a bottom cap cover 541 stacked with the bottom cap 503. The bottom cap cover 541 is shown as covering at least a portion of the bottom cap 503. The bottom cap cover 541 can include a layer of material of a selected thickness. The bottom cap cover 541 can define the shape and size of the rear surface l ib. Optionally, a portion of the bottom cap 503 not being covered by the bottom cap cover 541 can define an additional portion of the rear surface 1 lb. In one embodiment, the bottom cap cover 541 can be made of a thermally conductive material. Exemplary thermally conductive material can include conductive plastic, metal. For example, the bottom cap cover 541 can be made of an anodized metal.

[00351] The bottom assembly 546 is shown as defining an opening 548. The opening 548 can be a hole passing through an entire thickness of the bottom cap 503. The bottom cap cover

541 can thus connect with selected component(s) in the cavity 542 via the opening 548. In one embodiment, the bottom cap cover 541 can cover the opening 548 partially or entirely.

[00352] Turning to FIG. 52, an exemplary bottom assembly 546 is shown, with the bottom cap 503 and the bottom cap cover 541 illustrated both collectively (on the right) and individually (on the left top and bottom). Optionally, the opening 548 can be at least partially filled with an adhesive 535. In one embodiment, the adhesive 535 can include a thermal adhesive. The thermal adhesive can be thermally conductive so the temperature of selected component(s) in the cavity

542 (shown in FIG. 51) can be equalized with the temperature of the bottom cap cover 541. An exemplary thermal adhesive can include a thermal epoxy. The bottom cap 503 is shown as defining optional grooves 543, 545, for coating the adhesive 535 and for retaining overflow of the adhesive 535, respectively.

[00353] Turning to FIG. 53, the bottom cap 503, before modification for incorporating the device health sensor 530, is shown (on the left). The bottom cap 503, after modification for incorporating the device health sensor 530, is shown in a perspective view (on the bottom right). A cross sectioned bottom assembly 546 is shown in a perspective view (on the top right). [00354] The opening 548 can be of any selected size, shape and/or dimension, that is smaller than the size of the bottom cap 503 and/or the rear surface 1 lb (shown in FIG. 51). An exemplary opening 548 can have a circular shape with a diameter ranging from 6 mm to 10 mm. The opening 548 can be at any selected location on the bottom cap 503. An exemplary opening 548 can be located at the center of the bottom cap 503. Stated somewhat differently, the opening 548 and the bottom cap 503 can be concentric. The bottom cap cover 541 can increase an overall thickness of the guest device 11 (shown in FIG. 47) by a selected amount. In one embodiment, the increase of the thickness can range from 1 mm to 2 mm. FIG. 54 shows a cross sectional view of the cross sectioned bottom assembly 546 (also shown in the top right of FIG. 53). [00355] Turning to FIG. 55, the bottom assembly 546 and the device health sensor 530 are shown as being connected via a thermally conductive pathway 548. The thermally conductive pathway 548 can include any hardware, material, and/or heat transmission medium that acts as a thermal conduction connector between the bottom assembly 546 and the device health sensor 530. Accordingly, heat can be transferred between the device health sensor 530 and the bottom assembly 546, and the device health sensor 530 can detect the temperature of the bottom assembly 546 in an accurate manner.

[00356] In one embodiment, the thermally conductive pathway 548 can include a thermally conductive adhesive. An exemplary thermally conductive adhesive can include a thermal adhesive and/or a thermal epoxy.

[00357] Turning to FIG. 56, the guest device 11 is shown as including a sensor printed circuit board (sensor PCB) 534 having a first and second end portions 531, 532. In one embodiment, the first and second end portions 531, 532 can be located opposite to each other. The device health sensor 530 can be disposed on the second end portion 532. Stated somewhat differently, the device health sensor 530 can be integrated with the sensor PCB 534 to form a PCB assembly. The first end portion 531 is shown as being coupled to the PCBA 511 such that the sensor PCB 534 can be electrically connected to the microprocessor 603 of the PCBA 511 for sending measurement data or signal from the device health sensor 530 to the microprocessor 603.

[00358] Turning to FIG. 57, the sensor PCB 534 is shown as being capable of flexing. Stated somewhat differently, the sensor PCB 534 can be a flex PCB and/or being flexible. The sensor PCB 534 is shown as bending such that the first and second end portions 531, 532 can be parallel and facing each other. The first and second end portions 531, 532 can at least partially enclose other components, including the battery 507, of the guest device 11 therebetween, for example. Advantageously, the sensor PCB 534 can be accommodated in the guest device 11 without significantly increasing the size of the guest device 11. In one embodiment, the device health sensor 530 and the second end portion 532 can be proximal to and distal from the rear surface l ib (shown in FIG. 55), respectively. Optionally, the first and/or second end portions 531, 532 can be bonded and/or coupled with a stiffener for keeping a flat shape.

[00359] When the bottom assembly 546 includes the bottom cap 503 (shown in FIG. 50), the device health sensor 530 can be bonded to the bottom cap 503 via a thermally conductive adhesive. When the bottom assembly 546 includes the bottom cap cover 541 (shown in FIG. 51), the device health sensor 530 can be bonded to the bottom cap cover 541 via the adhesive 535 (shown in FIG. 52) that at least partially fills the opening 548.

[00360] Turning to FIG. 58, the sensor PCB 534 is shown as being located between the device health sensor 530 and the bottom assembly 546. As shown, the sensor PCB 534 does not necessarily need to be capable of flexing. The device health sensor 530 is shown as being disposed on the sensor PCB 534. The sensor PCB 534 can be connected to the PCBA 511 (shown in FIG. 5B-5D) via one or more conductive wires 533. The device health sensor 530 and the sensor PCB 534 are shown as being distal from and proximal to the rear surface 1 lb, respectively. [00361] When the bottom assembly 546 includes the bottom cap 503 (shown in FIG. 50), the sensor PCB 534 can be bonded to the bottom cap 503 via a thermally conductive adhesive. FIG. 58 shows the bottom assembly 546 as including the bottom cap cover 541 (also shown in FIG. 51), the sensor PCB 534 can be bonded to the bottom cap cover 541 via the adhesive 535 that at least partially fills the opening 548. Regardless of configuration of the bottom assembly 546, various methods can be used for enhancing heat transfer between the bottom assembly 546 and the device health sensor 530. For example, the sensor PCB 534 can be thermally conductive. In another example, the adhesive 535 can overflow to contact the device health sensor 530. In yet another example, the device health sensor 530 and the sensor PCB 534 can be proximal to and distal from the rear surface 1 lb, respectively, and thus be in different relative positions from the positions shown in FIG. 58.

[00362] Turning to FIG. 59, an exploded view of a part of the guest device 11 is shown to illustrate further details of the bottom assembly 546, the adhesive 535, the device health sensor 530 and the sensor PCB 534. The guest device 11 is shown as including an optional isolation layer 536 for thermally isolating the device health sensor 530 from other components (for example, the battery 507 shown in FIGS. 5B-5E) in the guest device 11. Advantageously, an effect of temperature variation of the other components on the device health sensor 530 can be reduced, and the device health sensor 530 can measure temperature of the bottom assembly 546 accurately. In one embodiment, the isolation layer 536 can include an isolation tape and/or insulation tape.

[00363] Turning to FIG. 60, an exemplary event priority table 550 for advertising packet is shown. In one embodiment, result of measurement by the device health sensor 530 (shown in FIG. 47) can be sent to the microprocessor 603 (shown in FIG. 47). The microprocessor 603 can generate device health data 538 (shown in FIG. 63) based upon the result. Exemplary device health data 538 can include temperature data presenting measurement result by the device health sensor 530. The microprocessor 603 can send the device health data 538 to a server 21 (shown in FIG. 63) via the wireless communication antenna 512 (shown in FIG. 47). The microprocessor 603 can send the device health data 538 via any selected communication protocol(s).

[00364] In some embodiments, the device health data 538 can be presented in advertising packet by overloading Received Signal Strength Indicator (RSSI) byte. The event priority table 550 shows events that are being overloaded. The two rows of priority “4” can be proposed events for the device health data 538. For example, the temperature data can be represented using single byte. The two nibbles can be transferred one by one and captured using one or more sensors 15 (shown in FIG. 63). The sensors 15 can include, for example, ultra-beam/spotlight sensors mounted on ceiling (other selected locations) of the facility. Advantageously, the device health data 538 can be captured by the sensors 15 live, in real time, and/or at short time intervals. [00365] Additionally and/or alternatively, the device health data 538 can be presented over BLE characteristic. The device health data 538 can be added as a new characteristic in existing medallion (and/or guest device) service. In one embodiment, when the user 52 (shown in FIG. 63) approaches near by a room, a processor (for example, an XAP processor of the interface device 17 (shown in FIG. 1 A) can be performing an authentication process every time. Thus, the device health data 538 can be read at the same time. Accordingly, the device health data 538 can be updated when the processor performs authentication.

[00366] In various embodiments, the device health data 538 can be presented in advertising packet and/or over BLE characteristic, without limitation. For example, the device health data 538 can be transmitted at a selected frequency, such as once per second, per minute and/or per hour. At a high frequency, the transmitted device health data 538 can be up to date but a higher power consumption by the guest device 11 (shown in FIG. 47) may be required. Thus, the frequency can be selected based upon a trade-off of timeliness of the transmitted device health data 538 and power consumption.

[00367] Turning to FIGS. 61-62, comparison tables 552 of a plurality of options of the device health sensor 530 are shown. The options 1-5 are unlimiting examples for illustrative purposes only. The device health sensor 530 can be selected from any of the options 1-5 that can sense a suitable range of temperature for the purpose of sensing temperature by the device health sensor 530.

[00368] In one embodiment, among the options, the suitable range of temperature can be a medium range for encompassing a normal human body temperature. Additionally and/or alternatively, selection can be based upon other factors such as power consumption, size, and/or the like. For example, compared with option 2 and option 5, option 1 has a smaller range of temperature but lower power consumption.

[00369] In some embodiments, accuracy and/or consistency of detecting the health function, such as the body temperature, by the guest device 11 can be improved when the device health sensor 530 is proximal to the same position on the body of the user 52 (shown in FIG. 63) at each measurement. For example, when worn on a wrist (or arm) of the user, the guest device 11 can preferably be wore on the left wrist at each measurement, or on the right wrist at each measurement. In one embodiment, the guest device 11 can be disposed in the accessory 201 (shown in FIG. 2B). The accessory 201 can be shaped or configured such that it is most secure and/or comfortable to the user 52 on only one of the wrists.

[00370] Turning to FIG. 63, the guest engagement system 10 is shown as including the plurality of guest devices 11 each being a wireless device. In various embodiments, the server 21 can be configured to be communicatively connected to each of the sensors 15 via the communication network 19 and storing the log associating each unique identifier of the guest device 11 detected by one of the sensors 15 with a known location of the sensor 15, a timestamp, and user health data 537. The user health data 537 can include any data associated with the health function(s) of the user 52 wearing the guest device 11. In various embodiments, the user health data 537 can be obtained by the sensors 15 and transmitted to server 21 via the communication network 19. In one embodiment, the user health data 537 can include the device health data 538 associated with the guest device 11. The guest device 11 can send the unique identifier and the device health data 538 to the sensor 15.

[00371] Turning now to FIG. 64, a diagram of an exemplary communication process 580 between the guest device 11 (shown in FIG. 63) and the sensor 15 (shown in FIG. 63) is shown. In various embodiments, the guest device 11 can store the device health data 538 (shown in FIG. 63) in the memory 601 (shown in FIG. 6). The communication between the guest device 11 and the sensor 15 can be implemented when the guest device 11 is in the bi-directional mode of operation. The guest device 11 can send, at 581, a ping at a selected frequency (for example, once every N second(s), N being a selected number). The guest device 11 can listen for a response from any of the sensors 15. Upon receiving the ping, one of the sensors 15 can send, at 582, a response to the guest device 11. Upon receiving the response from the sensor 15, the guest device 11 can determine that the guest device 11 has come into contact with the sensor 15. Accordingly, the guest device 11 can establish the secure communication channel between the guest device 11 and the sensor 15. 581 and 582 can be optional only. In some embodiments, the secure communication channel is been established in any other suitable manner without using 581 and/or 582.

[00372] The sensor 15 can send, at 583, a ‘fetch’ command to the guest device 11. The guest device 11 can send, at 584, the device health data 538 to the sensor 15 upon receiving the ‘fetch’ command. Stated somewhat differently, the guest device 11 can offload the device health data 538. For example, the guest device 11 can transfer the device health data 538 to the sensor 15 over BLE communications and/or NFC communications.

[00373] In some embodiments, 583 can be optional. Stated somewhat differently, the guest device 11 can send, at 584, the device health data 538 to the sensor 15 even without receiving the ‘fetch’ command. In one embodiment, the guest device 11 can send, at 584, the device health data 538 to the sensor 15 when the memory 601 is at a selected capacity, such as at a selected percentage of full capacity. An exemplary percentage can be greater than or equal to 75%. Thus, the guest device 11 can send the device health data 538 to a sensor 15 upon establishing the secure communication channel with the sensor 15, such that the device health data 538 can be timely removed from the memory 601 to generate more memory space.

[00374] Turning now to FIG. 65, a method 560 for health management for the facility using the guest engagement system 10 is shown. In some embodiments, the server 21 can implement the method 200. The user health data 537 can optionally be obtained at 561. The user health data 537 can be associated with the users 52 each wearing the guest device 11 in the facility. In one embodiment, the user health data 537 can at least partially based upon a measurement via one or more device health sensors 530 each associated with a user 52 of the facility. A health maintenance action can be determined, at 562, for the facility based upon the obtaining. The health maintenance action can include any actions related to maintenance of health of the facility and/or engaging the users or guests to improve overall health conditions, prevent an outbreak of a contagious or infectious disease, and/or control spreading of the contagious disease. Advantageously, the guest engagement system 10 can determine the health maintenance action accurately and in a customized manner based upon up-to-date information of users’ health conditions and locations.

[00375] In various embodiments, the device health sensor 530 can be configured to measure at least one health function associated with a symptom of an infectious disease. For example, a user 52 (shown in FIG. 63) with an infectious respiratory illness can have symptoms including fever, coughing, or a combination thereof. The guest devices 11 can detect the fever of user(s) 12 and transmit the device health data 538. The server 21 can thus obtain the user health data 537 indicating the fever and take the health maintenance action to keep the infectious disease from spreading. [00376] In one embodiment, the health maintenance action can include isolating and/or quarantining a user 52. For example, the server 21 can be configured to determine the user 52 that is to be isolated, and/or quarantined, from other users 52 based upon the user health data 537 indicating that the user 52 has a symptom of the infectious disease, such as a fever. Additionally and/or alternatively, the server 21 can monitor compliance of a user 52 that is under an isolation and/or quarantine protocol to enforce the protocol. In one embodiment, the server 21 can alert the user 52 and/or the crew member 40 (shown in FIG. 13) when the user 52 violates the protocol. For example, when the server 21 detects, via the guest device 11 that the user 52 moves beyond a prescribed range (for example, moves out of a cabin), the server 21 can send a message to a nearby crew member 40 and/or the user 52 (for example, on a mobile phone of the user 52) for reminding the user 52 of moving back in the prescribed range. Advantageously, spreading of the infectious disease can be controlled more effectively.

[00377] Additionally and/or alternatively, the health maintenance action can include cleaning a location (or venue), or setting a priority thereof. In one embodiment, the server 21 can be configured to determine a level of priority for cleaning a selected location based upon the user health data 537 associated with the users 52 that have visited (or been proximal to) the location. For example, the server 21 can determine the level of priority based upon a duration of a selected user 52 at the location, a number of the users 52 that have visited the location during a time period such that they have interaction with the user 52, an importance of the location, or a combination thereof.

[00378] Turning now to FIG. 66, the user health data 537 is shown as including system health data 539. Stated somewhat differently, the user health data 537 can include the device health data 538, system health data 539, or a combination thereof. The system health data 539 can include result of measurement of at least one health function of a user 52 by suitable equipment of the guest engagement system 10 but not by the guest device 11. The system health data 539 can supplement and/or substitute the device health data 538 when the device health data 538 is not accurate or timely. Advantageously, the user health data 537 can be more accurate and up-to-date.

[00379] The guest engagement system 10 is shown as further including one or more system health sensors 50 for measuring the health function of the user 52, generating the system health data 539 based upon the measurement, and sending the system health data 539 to the server 21 via a sensor 15 and/or directly (or not via the sensor 15). In one embodiment, the system health sensor 50 can include a temperature scanner for measuring body temperature of the user 52 in a contact and/or non-contact manner. An exemplary system health sensor 50 can include a non-contact body temperature scanner, such as a forehead temperature scanner and/or an ear temperature scanner, for example. For example, the system health sensor 50 can measure the temperature of a temple of the forehead using any suitable methods.

[00380] Each of the system health sensors 50 can optionally be associated with a selected sensor. Each system health sensor 50 can have a known location and can be used to implement measurement of the users 52 of the guest devices 11. One or more of the system health sensors 50 are shown as each being associated with a sensor 15, respectively. For example, a system health sensor 50 and an associated sensor 15 can be located proximal to each other, positioned within a predetermined distance, and/or oriented in a manner such that the sensor 15 can detect the guest device 11 carried by a user 52 and, simultaneously and/or within a preset time interval, the system health sensor 50 can perform measurement of the health function of the same user 52. For example, when the guest device 11 in range for the sensor 15, a body part (for example, forehead) of the user 52 can be in the scanning range of the system health sensor 50 so the system health sensor 50 can measure the temperature of the forehead. Thus, when the user 52 is authenticated at the sensor 15 to access a venue or interface device 17 (shown in FIG. 1A), the body temperature of the user 52 can be measured. Additionally and/or alternatively, the sensing range of the sensor 15 (e.g., shape and orientation of a directional sensing range) can overlap with a health function measurement range (for example, temperature-detection range) of the system health sensor 50 when the sensor 15 and the system health sensor 50 are in proximity. The system health sensor 50 and the associated sensor 15 are shown as collectively forming a health-detection sensor group 55.

[00381] In one example, the system health sensor 50 and the associated sensor 15 can be integrated into a module or assembly, be in communication, and/or share the same sensor network peripherals 14 (shown in FIG. IB). Additionally and/or alternatively, the selected sensor 15 and the selected system health sensor 50 can reside on separate hardware components and/or include intermediate hardware, such as the sensor network peripherals 14. [00382] In another example, the system health sensor 50 and the associated sensor 15 can be located in the vicinity of each other, not being in connection or communication with each other, but respectively being in communication with the server 21.

[00383] In various embodiments, the server 21 can determine a health status of the user 52 based upon the user health data 537. In one embodiment, the server 21 can determine the health status of the user 52 based upon only the system health data 539 or only the device health data 538. For example, if the system health sensor 50 is more accurate than the device health sensor 530, the server 21 can use the system health data 539 only.

[00384] In another embodiment, the server 21 can correct (and/or modify) the device health data 538 based upon the system health data 539. For example, the system health sensors 50 can be more accurate than the device health sensor 530, but can only measure the user 52 at a lower frequency than the device health sensor 530. In that case, the server 21 can obtain measurements of the device health sensor 530 that occur between two measurements of the system health sensors 50, determine a systematic error of the device health sensor 530 by comparing with the two measurements of the system health sensors 50, and correct the systematic error of the device health sensor 530 accordingly, such that the corrected device health data 538 can be used. In yet another embodiment, the server 21 can correct (and/or modify) the system health data 539 based upon the device health data 538.

[00385] Additionally and/or alternatively, the server 21 can smooth the user health data 537. The server 21 can use any suitable data smoothing techniques on the device health data 538 and/or the system health data 539 to remove outliers. Exemplary data smoothing techniques can include averaging, random method, simple moving average, random walk, simple exponential, and exponential moving average, or a combination thereof. Additionally and/or alternatively, the server 21 can remove noise, and/or false positive/negative data based upon characteristics of locations in the facility. For example, at a venue where the user 52 is likely to be proximal to heated elements (for example, fireplace or hot food), the device health data 538 may have a high probability of obtaining false positives of high body temperature. The server 21 can thus identify data points indicating sporadic high body temperature in such a venue and exclude such data points from the device health data 538 and/or the user health data 537.

[00386] Additionally and/or alternatively, the device health data 538 can be transmitted from the guest device 11 in a manner as set forth in FIGS. 43 -46b. Although FIGS. 63 and 65 each depict the user health data 537 as including the device health data 538 for illustrative purposes only, the user health data 537 can include the system health data 539 with and/or without the device health data 538. Stated somewhat differently, in some embodiments, the guest engagement system 10 can implement the method 560 even if the guest device 11 does not include the device health sensor 530 or does not generate the device health data 538.

[00387] FIG. 67 shows an exemplary user interface (or computer interface) 554 presenting an individual relationship matrix that illustrates an interaction dwell time between a selected user 52 and other users 52 at selected location(s) on selected day(s). Such information can be used for determining priority for cleaning the locations. The user interface 554 can include charts 558 to illustrate overlap of locations that the users 52 interact in.

[00388] FIG. 68 shows an exemplary user interface 556 presenting interactions between the selected user 52 and other users 52 over a period of a time (for example, a week). The user interface 556 can supplement the user interface 554 (shown in FIG. 67) to facilitate assessment of individual risk for the users 52 that have been in contact with an infected user 52 (for example, a patient zero).

[00389] FIG. 69 shows an exemplary user interface 551 presented by the server 21 (shown in FIG. 63) to instruct crew members on the location(s) to clean first and time for the cleaning. In one embodiment, each interval for cleaning can be colored according to the level of priority. [00390] FIG. 70 shows an exemplary user interface 553. The server 21 (shown in FIG. 63) can be configured to create a digital clone of each of the users 52. The server 21 can generate the user interface 553 to present the digital clone(s) and optionally the health status (and/or the user health data 537) thereof. Advantageously, the health status, and location and time thereof, of the users 52 can be shown in an intuitive and vivid manner. The digital clones can optionally be three-dimensional models of the users 52. The server 21 can use any suitable tool and/or platform for creating and/or presenting the digital clone.

[00391] In one embodiment, the user health data 537 can include the body temperature. The digital clone can be color-coded based upon the body temperature. For example, a high temperature can be show with a warm color (or a color with a longer wavelength). Stated somewhat differently, the digital clones with a high body temperature (or fever), a low fever, a normal temperature, a lower-than normal temperature, can be red, yellow, light blue, and blue, respectively. [00392] Additionally and/or alternatively, based on known locations and timestamps associated with the user health data 537, the user interface 553 can show a snapshot of the users 52 moving throughout the facility, replay, and/or play in real time an animation showing movement of the users 52 over time. Advantageously, interaction between users 52 can be shown in a realistic view and tracking of the users 52 can be facilitated.

[00393] Turning now to FIG. 71, another exemplary user interface 555 is shown. The server 21 can generate the user interface 555 to present the digital clone(s) for user tracking and/or generating a contact point list. For example, for a user 52 (shown in FIG. 63) having a fever, the user interface 555 can present a map (or a heatmap) to track contact points for the locations that the user 52 visits. The locations can thus be cleaned, and other users 52 being in contact with the users 52 can be alerted and be put under isolation and/or quarantine. Advantageously, spreading of the infectious disease can be timely controlled.

[00394] In various embodiments, the server 21 (shown in FIG. 63) can include one or more computer hardware platforms as shown in FIGS. 11 and/or 12. However, the server 21 may need to be programmed with specialized coded instruction to implement the various methods and/or systems as set forth above.

[00395] Various embodiments set forth the guest engagement system 10 that includes one or more temperature sensors integrated therein. An exemplary guest engagement system 10 can be used on cruise ships to detect any dramatic temperature changes in guests.

[00396] In one embodiment, the guest engagement system can be integrated with temperature sensors via addition of a temperature sensor to the medallion. This can include the placement of a temperature sensor on a flexible printed circuit, attached to the main printed circuit board of the medallion, and placed in contact with the bottom cap of the medallion through a variety of means (e.g., in contact with a metallic button located in the middle of the bottom of the cap or in direct contact with a thermally conductive plastic as the bottom cap).

[00397] Therefore, in accordance with various embodiments, a temperature sensing device cooperating with the medallion can be configured to provide for the inclusion of temperature data included in every data packet. The temperature sensing device can allow for the nearly continuous awareness of changes in the temperature environment of the wearer when worn in an accessory, and/or carried with the wearer. The temperature sensing device can allow for the general awareness of the individuals or clusters of individuals who may have and/or be having the effect of significant changes in environmental and/or personal temperatures.

[00398] The temperature sensing device cooperating with the medallion can be configured to provide for the specific temperature measurement of an individual when in contact with the skin.

[00399] Various embodiments set forth the guest engagement system 10 that can implement a highly scalable wearable/xIOT (Internet of Things) ecosystem enabled concept (including process, system, operation and/or technology). The concept can leverage a real-time “digital clone” (for physical environments, objects and/or humans) to provide biological and location based telemetry awareness of an individual (for example, guest/crew/team) and/or individual associations (travel groups, direct and/or indirect) relative health as determined by relative body temperature of an individual and individual associations to each other and the entire population. The concept can thus provide an overall health perspective of a ship and/or a specific venue and/or provide operational direction on medical/health directives to isolate and/or quarantine specific individuals of specific groups to minimize risk to the entire population (for example, guest/crew/team).
