BACKGROUND

Current automated item tracking mechanisms often utilize wireless data transmission protocols to identify the location and/or identity of various items to be tracked. Without those wireless data transmissions, the automated item tracking mechanisms are unable to identify the location of items without some human interaction. This limitation becomes particularly acute in instances in which wireless data transmissions are undesirable, which severely limits the functionality of tracking mechanisms. Users of the tracking systems may be required to manually disable wireless data transmissions in certain instances, thereby temporarily disabling the automated tracking mechanism until wireless data transmissions are acceptable once again. However, human error often results in such wireless data transmission mechanisms being inappropriately left in an active state when such wireless transmissions are undesirable, and/or such wireless data transmission mechanisms being inappropriately left in an inactive state when wireless transmissions are once again acceptable for item tracking.

Accordingly, a need exists for automated item tracking mechanisms configured to automatically disable and/or enable wireless data transmissions to maximize the effectiveness of wireless item tracking mechanisms.

BRIEF SUMMARY

Various embodiments are directed to systems and methods for tracking the location of containers and/or other assets via a plurality of beacons that may be configurable between a plurality of operating modes including an advertising mode, a listening mode, and a sleep mode. The various operating modes enables the beacons to be utilized in environments in which constant transmission of advertising data is not desirable (e.g., on aircraft), while enabling automatic location of the containers and/or assets during periods of time in which wireless data transmission is desirable.

In certain embodiments, a system for monitoring the location of one or more assets may comprise: one or more status sensors; one or more wireless network interfaces; and one or more processors configured to: monitor the one or more status sensors to determine the occurrence of one or more trigger states; upon detecting that a trigger state is not present, configure the one or more network interfaces into a listening mode, wherein the one or more wireless network interfaces are configured to receive wireless signals broadcast by third party computing entities while in the listening mode; upon detecting that one or more wireless signals are received by the wireless network interfaces, configuring the one or more wireless network interfaces into an advertising mode, wherein the one or more wireless network interfaces are configured to broadcast one or more signals while in the advertising mode; and upon detecting that a trigger state is present, configure the one or more network interfaces into a sleep mode.

Moreover, in certain embodiments, a method for monitoring the location of one or more assets may comprise steps for: providing one or more wireless beacons on each of the one or more assets, wherein each of the one or more wireless beacons comprise one or more status sensors and one or more wireless network interfaces; monitoring the one or more status sensors to determine the occurrence of one or more trigger states; upon detecting that a trigger state is not present, configuring the one or more network interfaces into a listening mode, wherein the one or more wireless network interfaces are configured to receive wireless signals broadcast by third party computing entities while in the listening mode; upon detecting that one or more wireless network interfaces are received by the wireless network interfaces, configuring the one or more wireless network interfaces into an advertising mode, wherein the one or more wireless network interfaces are configured to broadcast one or more signals while in the advertising mode; and upon detecting that a trigger state is present, configuring the one or more network interfaces into a sleep mode.

In certain embodiments, a system for monitoring the location of one or more assets may comprise: a location determining device secured to a powered asset, the location determining device configured to detect a location and heading of the powered asset; at least one powered asset beacon secured to the powered asset, wherein the at least one powered asset beacon is configured to detect signals transmitted from one or more asset beacons secured to one or more assets while the asset beacons are positioned within a transmission range of the powered asset beacon; at least one camera secured relative to the powered asset and having a known orientation relative to the powered asset; and a controller configured to: detect at least one signal emitted from an asset beacon secured relative to an asset; detect the asset within an image captured by the at least one camera; and determine the location of the asset based at least in part on the location and the heading of the powered asset and a signal strength of the signal emitted from the asset beacon.

Additionally, while Figure 1 illustrates certain system entities as separate, standalone entities, the various embodiments are not limited to this particular architecture. a. Exemplary Powered Asset

In various embodiments, the term powered asset 100 is used generically. For example, a powered asset 100 maybe a tug, tractor, truck, car, van, flatbed, vehicle, aircraft- pushback tractor, cargo loader, forklift, and/or the like. As will be recognized, in many cases, a powered asset 100 may be configured to push, pull, lift, or otherwise move a non- powered asset 103. Further, each powered asset 100 may be associated with a unique powered asset identifier (such as a powered asset ID) that uniquely identifies the powered asset 100. The unique powered asset ID may include characters, such as numbers, letters, symbols, and/or the like. For example, an alphanumeric powered asset ID (e.g., "AS445") may be associated with each powered asset 100. In another embodiment, the unique powered asset ID may be a registration number or other identifying information/data assigned to the powered asset 100.

Figure 1 shows one or more computing entities, devices, and/or similar words used herein interchangeably that are associated with the powered asset 100, such as an information/data collection device 130 or other computing entities. In general, the terms computing entity, entity, device, system, and/or similar words used herein interchangeably may refer to, for example, one or more computers, computing entities, desktop computers, mobile phones, tablets, phablets, notebooks, laptops, distributed systems, watches, glasses, beacons, key fobs, radio frequency identification (RFID) tags, ear pieces, scanners, televisions, dongles, cameras, wristbands, wearable items/devices, items/devices, kiosks, input terminals, servers or server networks, blades, gateways, switches, processing devices, processing entities, set-top boxes, relays, routers, network access points, base stations, the like, and/or any combination of devices or entities adapted to perform the functions, operations, and/or processes described herein. Figure 2 provides a block diagram of an exemplary information/data collection device 130 that may be attached, affixed, disposed upon, integrated into, or part of a powered asset 100. The information/data collection device 130 may collect telematics information/data (including location data) and transmit/send the information/data to the mobile computing entity 105, the tracking computing entity 110, and/or various other computing entities via one of several communication methods.

In one embodiment, the information/data collection device 130 may include, be associated with, or be in wired or wireless communication with one or more processors 200 (various exemplary processors are described in greater detail below), one or more location- determining devices or one or more location sensors 120 (e.g., Global Navigation Satellite System (GNSS) sensors), one or more telematics sensors 125, one or more real-time clocks 215, a J-Bus protocol architecture, one or more electronic control modules (ECM) 245, one or more communication ports 230 for receiving telematics information/data from various sensors (e.g., via a CAN-bus), one or more communication ports 205 for transmitting/sending data, one or more RFID tags/sensors 250, one or more power sources 220, one or more information/data radios 235 for communication with a variety of communication networks, one or more memory modules 210, and one or more programmable logic controllers (PLC) 225. It should be noted that many of these components may be located in the powered asset 100 but external to the information/data collection device 130. Thus, each of the components may be referred to individually or collectively as a powered asset computing entity.

In one embodiment, the one or more location sensors 120, modules, or similar words used herein interchangeably may be one of several components in wired or wireless communication with or available to the information/data collection device 130. Moreover, the one or more location sensors 120 may be compatible with GPS satellites 115, such as Low Earth Orbit (LEO) satellite systems, Department of Defense (DOD) satellite systems, the European Union Galileo positioning systems, Global Navigation Satellite systems (GLONASS), the Chinese Compass navigation systems, Indian Regional Navigational satellite systems, and/or the like. Furthermore, the one or more location sensors 120 may be compatible with Assisted GPS (A-GPS) for quick time to first fix and jump starting the ability of the location sensors 120 to acquire location almanac and ephemeris data, and/or be compatible with Satellite Based Augmentation System (SBAS) such as Wide Area Augmentation System (WAAS), European Geostationary Navigation Overlay Service (EGNOS), and/or MTSAT Satellite Augmentation System (MSAS), GPS Aided GEO Augmented Navigation (GAGAN) to increase GPS accuracy. This information/data can be collected using a variety of coordinate systems, such as the Decimal Degrees (DD); Degrees, Minutes, Seconds (DMS); Universal Transverse Mercator (UTM); Universal Polar Stereographic (UPS) coordinate systems; and/or the like. Alternatively, triangulation may be used in connection with a device associated with a particular powered asset and/or the powered asset's operator and with various communication points (e.g., cellular towers or Wi-Fi access points) positioned at various locations throughout a geographic area to monitor the location of the powered asset 100 and/or its operator. The one or more location sensors 120 may be used to receive latitude, longitude, altitude, heading or direction, geocode, course, position, time, and/or speed information/data (e.g., referred to herein as telematics information/data and further described herein below). The one or more location sensors 120 may also communicate with the tracking computing entity 110, the information/data collection device 130, mobile computing entity 105, and/or similar computing entities.

As indicated, in addition to the one or more location sensors 120, the information/data collection device 130 may include and/or be associated with one or more telematics sensors 125, modules, and/or similar words used herein interchangeably. For example, the telematics sensors 125 may include powered asset sensors, such as engine, fuel, odometer, hubometer, tire pressure, location, weight, emissions, door, and speed sensors. The telematics information/data may include, but is not limited to, speed data, emissions data, RPM data, tire pressure data, oil pressure data, seat belt usage data, distance data, fuel data, idle data, and/or the like (e.g., referred to herein as telematics data). The telematics sensors 125 may include environmental sensors, such as air quality sensors, temperature sensors, and/or the like. Thus, the telematics information/data may also include carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), Ethylene Oxide (EtO), ozone (O3), hydrogen sulfide (H2S) and/or ammonium (NH4) data, and/or meteorological information/data (e.g., referred to herein as telematics data). In one embodiment, the ECM 245 may be one of several components in communication with and/or available to the information/data collection device 130. The ECM 245, which may be a scalable and subservient device to the information/data collection device 130, may have information/data processing capability to decode and store analog and/or digital inputs from powered asset systems and sensors. The ECM 245 may further have information/data processing capability to collect and present telematics information/data to the J-Bus (which may allow transmission to the information/data collection device 130), and output standard powered asset diagnostic codes when received from a powered asset' s J-Bus-compatible on-board controllers 240 and/or sensors.

Additionally, each powered asset 100 may have one or more powered asset beacons

150 attached or affixed thereto. As will be recognized, a beacon may take many forms. For instance, a beacon may be a Bluetooth Low Energy (BLE) beacon (e.g., a URIBeacon, an AltBeacon, or an iBeacon), an RFID tag/sensor, a near field communication (NFC) device, a Wi-Fi device, and/or the like. The powered asset beacons 150 may include some or all of the following components: one or more input interfaces for receiving information/data, one or more output interfaces for transmitting information/data, a processor, a clock, memory modules, one or more sensors for sensing and detecting various information/data (e.g., wireless signal sensors), a camera, and a power source. The power source may be a source provided by the powered asset, an energy storage device (e.g., a battery, a supercapacitor, and/or the like), an energy harvesting device (e.g., a solar panel, a vibration energy harvester, a thermal energy harvester, a RF energy harvester, and/or the like), and/or the like. In one embodiment, each powered asset beacon 150 can store one or more unique identifiers, such as a global unique identifier (GUID), a universally unique identifier (UUID), a character string, an alphanumeric string, text string, and/or the like. The unique identifier may identify the associated powered asset 100 and/or powered asset beacon. Via various communication standards and protocols, the powered asset beacon 150 associated with the powered asset 100 can be communicated with, interrogated, read, and/or the like. For example, a container beacon 155 associated with a container 107 can communicate with the powered asset beacon 150 associated with the power asset 100 using multiple wireless communication standards and protocols, including Bluetooth, Wibree, NFC, Wi-Fi, ZigBee, and/or any other wireless protocol or standard. For example, the one or more powered asset beacons 150 may be configured to communicate with one or more container beacons 155 via one or more configurations as described in U.S. Patent No. 9,658,310, the contents of which is incorporated herein by reference in its entirety. As a specific example, the one or more powered asset beacons 150 may collective define a communication area within the powered asset 100 in which the container beacon 155 may communicate with one or more of the powered asset beacons 150. Upon establishing a wireless communication connection with a threshold number of powered asset beacons 150 associated with a single powered asset 100, the container beacon 155 may be determined to be associated with the powered asset 100, as discussed in greater detail herein. The powered asset beacon 150 associated with the powered asset 100 may also be in direct or indirect communication with the tracking computing entity 110, the information/data collection device 130, mobile computing entity 105, and/or similar computing entities over the same or different wired or wireless networks.

As will be recognized, a powered asset beacon 150 can be used to sense and/or detect various information/data. For example, a powered asset beacon 150 can be capable of sensing temperature information/data, pressure information/data, altitude information/data, vacuum information/data, vibration information/data, shock information/data, humidity information/data, moisture information/data, light information/data, air information/data, heading information/data, battery level information/data, and/or the like. In one embodiment, a powered asset beacon 150 may be operated in one or more operating modes, such as advertising mode, listening mode, sleep mode, and/or the like. In advertising mode, the powered asset beacon 150 may transmit one or more advertising signals regularly, periodically (e.g., 10 times/second), and/or continuously. The one or more advertising signals may include one or more unique identifiers (e.g., powered asset information and/or unique powered asset beacon identifier), received signal strength indicator (RSSI), and/or other information/data. In listening mode, the powered asset beacon 150 is capable of receiving one or more signals transmitted by other beacons and/or other computing entities. In sleep mode, the powered asset beacon 150 may cut power to unneeded subsystems and place the other subsystems (e.g., receiver, processor) into a configurable low power state (e.g., with just sufficient power for the powered asset beacon 150 to detect triggers/events for it to change/switch from sleep mode into other operational modes (e.g., listening mode, advertising mode)). The change of the operational mode may be triggered by various configurable triggers/events, such as pressure, altitude, motion, location, light, sound, time, one or more signals transmitted from another beacon and/or an appropriate computing entity, a switch, a button, combinations thereof, and/or the like.

As noted, the powered asset beacon 150 may comprise a camera (e.g., a video camera, a still camera, and/or the like) configured for collecting visual data regarding an environment surrounding the powered asset beacon 150. The camera may have a fixed field of view (FOV) relative to the camera, comprising a defined angle within the FOV relative to the camera. For example, the FOV of the camera may comprise a 15 degree FOV (e.g., encompassing a cone having a 15 degree side-slope centered at a lens of the camera), a 30 degree FOV, a 10 degree FOV, and/or the like. Moreover, the FOV may extend a defined distance away from the camera (e.g., 10 feet, 20 feet, 30 feet, and/or the like). For example, the length of the FOV of the camera may correspond to the expected detection distance of the wireless signal receiver of the powered asset beacon 150.

Moreover, the camera may have a known orientation relative to the powered asset 100, such that the heading of the powered asset (and/or powered asset beacon 150) may be utilized to determine the location of the FOV of the camera relative to the heading of the powered asset 100. In certain embodiments, the camera orientation may be fixed relative to the powered asset 100, or the camera orientation may be movable relative to the powered asset 100. In the latter embodiments, the orientation of the camera may be tracked to monitor the orientation of the camera relative to the heading of the powered asset 100.

Thus, as discussed in greater detail herein, the detection of a container 107 (and/or other asset) within the FOV of the camera may be utilized to determine the location of the container 107 relative to the powered asset 100 based on the known orientation of the FOV of the camera relative to the heading of the powered asset 100. As a specific example, in an embodiment in which the FOV of the camera extends directly behind the powered asset 100 (as shown in Figure 8), and the powered asset 100 is known to be pointing due north at a given location, the detection of a container 107 within the FOV of the camera may be utilized to determine that the container 107 is due south of the powered asset 100 by a distance less than or equal to the length of the FOV of the camera relative to the given location.

In certain embodiments, the camera and/or other aspects of the powered asset beacon

150 may be configured for performing optical character recognition (OCR) on one or more images collected by the camera. As discussed in greater detail herein, containers 107 may have identifying information (e.g., alphanumeric strings) printed or otherwise disposed on one or more sidewalls of the containers. The powered asset beacon 150 may thus be configured to recognize the identifying information on a container visible within the FOV of the camera (e.g., via OCR), and may utilize the recognized identifying information to augment and/or improve the accuracy of the wireless information/data to precisely and accurately identify the location of the container 107. As indicated, a communication port 230 may be one of several components available in the information/data collection device 130 (or be in or as a separate computing entity). Embodiments of the communication port 230 may include an Infrared information/data Association (IrDA) communication port, an information/data radio, and/or a serial port. The communication port 230 may receive instructions for the information/data collection device 130. These instructions may be specific to the powered asset 100 in which the information/data collection device 130 is installed, specific to the geographic area in which the powered asset 100 will be traveling, specific to the function the powered asset 100 serves within a fleet, and/or the like. In one embodiment, the information/data radio 235 may be configured to communicate with a wireless wide area network (WW AN), wireless local area network (WLAN), wireless personal area network (WPAN), or any combination thereof. For example, the information/data radio 235 may communicate via various wireless protocols, such as 802.11, general packet radio service (GPRS), Universal Mobile Telecommunications System (UMTS), Code Division Multiple Access 2000 (CDMA2000), CDMA2000 IX (lxRTT), Wideband Code Division Multiple Access (WCDMA), Global System for Mobile Communications (GSM), Enhanced Data rates for GSM Evolution (EDGE), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), Evolved Universal Terrestrial Radio Access Network (E-UTRAN), Evolution-Data Optimized (EVDO), High Speed Packet Access (HSPA), High-Speed Downlink Packet Access (HSDPA), IEEE 802.11 (Wi-Fi), Wi-Fi Direct, 802.16 (WiMAX), ultra wideband (UWB), infrared (IR) protocols, NFC protocols, Wibree, Bluetooth protocols (including Bluetooth Low Energy (BLE)), wireless universal serial bus (USB) protocols, and/or any other wireless protocol. b. Exemplary Non-Powered Assets

In various embodiments, a non-powered asset 103 may be any dolly, trailer, chassis, stacker truck, side loader, pallet truck, hand truck, handcart, roller deck, slave pallet, container trailer, pallet trailer, cargo trailer, cargo cart and/or the like. As will be recognized, a non-powered asset 103 may be configured to be pushed, pulled, lifted, or otherwise moved. The non-powered asset 103 may transport one or more one or more containers 107 storing one or more items 109 (which may be stored in containers 107). Further, each non-powered asset 103 may be associated with a unique non-powered asset identifier (such as a non- powered asset ID) that uniquely identifies the non-powered asset 103. The unique non- powered asset ID may include characters, such as numbers, letters, symbols, and/or the like. For example, an alphanumeric non-powered asset ID (e.g., '7221A445533AS449") may be associated with each non-powered asset 103.

In one embodiment, each non-powered asset 103 may be associated with one or more RFID tags/sensors, beacons, computing entities, and/or the like. In one embodiment, each non-powered asset 103 can be capable of sensing temperature information/data, pressure information/data, altitude information/data, vacuum information/data, vibration information/data, shock information/data, humidity information/data, moisture information/data, light information/data, air information/data, heading information/data, battery level information/data, and/or the like. Thus, each non-powered asset may be configured to collect information/data and communicate various information/data using multiple wireless communication standards and protocols, such as GPRS, UMTS, CDMA2000, lxRTT, WCDMA, TD-SCDMA, LTE, E-UTRAN, EVDO, HSPA, HSDPA, Wi-Fi, WiMAX, UWB, IR protocols, Bluetooth protocols, USB protocols, and/or any other wireless protocol.

In certain embodiments, the non-powered assets 103 may comprise and/or be associated with one or more non-powered asset beacons (not shown) having a configuration analogous to the powered asset beacons 150 described herein. In such embodiments, the various container beacons 155 may be configured to selectably initiate wireless communication with the non-powered asset beacons in a manner described in reference to the wireless communication between the container beacons 155 and the powered asset beacons 150.

Moreover, the non-powered assets beacons may comprise one or more cameras having known orientations relative to the non-powered assets, as discussed in reference to the powered asset beacons 150, above. Accordingly, as discussed above, the non-powered asset beacons may be utilized to determine a directional location of one or more containers relative to the position of the non-powered asset 103. c. Containers and/or Items

In one embodiment, a container 107 is configured to store and transport one or more items (e.g., shipments, packages, pallets, etc.) of varying shapes and sizes. For instance, in various embodiments, a container 107 may be a unit load device (ULD) used to store and transport items 109 on an aircraft. An item 109 may be any tangible and/or physical object. In one embodiment, an item may be or be enclosed in one or more packages, envelopes, parcels, bags, goods, products, loads, crates, items banded together, drums, the like, and/or similar words used herein interchangeably.

In one embodiment, each container 107 and/or item 109 may include and/or be associated with unique a tracking identifier, such as an alphanumeric identifier. Such tracking identifiers may be represented as text, barcodes, tags, character strings, Aztec Codes, MaxiCodes, information/data Matrices, Quick Response (QR) Codes, electronic representations, and/or the like. A unique tracking identifier (e.g., 1Z123456789) may be used by a carrier to identify and track containers 107 and items 109 as they move through a carrier's transportation network. For example, information/data comprising a tracking identifier can be read, scanned, transmitted, and/or the like to provide and/or identify/determine the location of a container 107 and/or item 109. As will be recognized, items 109 can be associated with a container 107 and therefore associated items 109 can considered to be located in the container 107 at the determined location of the container 107. These can be referred to as "logical" scans/determinations or "virtual" scans/determinations.

Such tracking identifiers can be affixed to items by, for example, using a sticker (e.g., label) with the unique tracking identifier printed thereon (in human and/or machine readable form). In other embodiments, a container beacon 155 or an RFID tag may be affixed to or associated with each container 107 and/or item 109 and store a unique tracking identifier. As previously noted, a beacon may take many forms. For example, a beacon may be a BLE beacon (e.g., a URIBeacon, an AltBeacon, or an iBeacon), an RFID tag/sensor, an NFC device, a Wi-Fi device, and/or the like. The container beacon 155 can include some or all of the following components: one or more input interfaces for receiving information/data, one or more output interfaces for transmitting information/data, a processor, a clock, memory modules, one or more sensors for sensing and detecting various information/data, and a power source. The power source may be an energy storage device (e.g., a battery, a supercapacitor, and/or the like), an energy harvesting device (e.g., a solar panel, a vibration energy harvester, a thermal energy harvester, a RF energy harvester, and/or the like), and/or the like. In one embodiment, each container beacon 155 can store one or more unique identifiers, such as a GUID, a UUID, a character string, an alphanumeric string, text string, and/or the like. The unique identifier may identify the associated container 107 (and/or item 109) and/or container beacon 155. Via various communication standards and protocols, the container beacon 155 associated with the container 107 and/or item 109 can be communicated with, interrogated, read, and/or the like. For example, the container beacon 155 associated with the container 107 and/or item 109 can communicate with a powered asset beacon 150 associated with a powered asset 100 using multiple wireless communication standards and protocols, including Bluetooth, Wibree, NFC, Wi-Fi, ZigBee, and/or any other wireless protocol or standard. The container beacon 155 associated with the container 107 and/or item 109 may also be in direct or indirect communication with a tracking computing entity 110, an information/data collection device 130, a mobile computing entity 105, and/or similar computing entities over the same or different wired or wireless networks.

As will be recognized, a container beacon 155 can be used to sense and detect various information/data. For example, a container beacon 155 can be capable of sensing temperature information/data, pressure information/data, altitude information/data, vacuum information/data, vibration information/data, shock information/data, humidity information/data, moisture information/data, light information/data, air information/data, heading/directional information data, battery level information data, and/or the like. In one embodiment, a container beacon 155 may be operated in one or more operating modes, such as advertising mode, listening mode, sleep mode, and/or the like. In advertising mode, the container beacon 155 may transmit one or more advertising signals regularly, periodically (e.g., 10 times/second), and/or continuously. The one or more advertising signals may include one or more unique identifiers (e.g., unique container identifier and/or unique container beacon identifier), RSSI, and/or other information data. In listening mode, the container beacon 155 is capable of receiving one or more signals transmitted by other beacons, and/or an appropriate computing entities. In sleep mode, the container beacon 155 may cut power to unneeded subsystems and place the other subsystems (e.g., receiver, processor) into a configurable low power state (e.g., with just sufficient power for the container beacon 155 to detect triggers/events for it to change/switch from sleep mode into other operational modes (e.g., listening mode, advertising mode)). The change of the operational mode may be triggered by various configurable triggers/events, such as pressure, altitude, motion, light, location, sound, time, one or more signals transmitted from another beacon and/or an appropriate computing entity, a switch, a button, combinations thereof, and/or the like.

Although the following discussion focuses on the tracking and/or monitoring of the location of containers 107 specifically, it should be understood that concepts discussed herein may be utilized to track and/or monitor the location of any of a variety of assets, including, without limitation, containers 107 (as discussed directly herein), powered assets 100, nonpowered assets 103, employees (e.g., carrying a beacon), mobile computing entities, objects, and/or the like. d.

Figure 4 provides an illustrative schematic representative of a mobile computing entity 105 that can be used in conjunction with embodiments of the present invention. In one embodiment, a mobile computing entity may be carried for use by carrier personnel. In one embodiment, the mobile computing entities 105 may include one or more components that are functionally similar to those of the tracking computing entity 110 and/or as described below. As will be recognized, mobile computing entities 105 can be operated by various parties, including personnel loading, unloading, delivering, transporting containers 107 and/or items 109.

The one or more signals provided to and received from the transmitter 404 and the receiver 406, respectively, may include signaling information/data in accordance with an air interface standard of applicable wireless systems to communicate with various entities, such as powered assets 100, tracking computing entities 110, and/or the like. In this regard, the mobile computing entity 105 may be capable of operating with one or more air interface standards, communication protocols, modulation types, and access types. More particularly, the mobile computing entity 105 may operate in accordance with any of a number of wireless communication standards and protocols. In a particular embodiment, the mobile computing entity 105 may operate in accordance with multiple wireless communication standards and protocols, such as GPRS, UMTS, CDMA2000, lxRTT, WCDMA, TD- SCDMA, LTE, E-UTRAN, EVDO, HSPA, HSDPA, Wi-Fi, WiMAX, UWB, IR protocols, Bluetooth protocols, USB protocols, and/or any other wireless protocol.

The mobile computing entity 105 can also download changes, add-ons, and updates, for instance, to its firmware, software (e.g., including executable instructions, applications, program modules), and operating system.

According to one embodiment, the mobile computing entity 105 may include location determining aspects, devices, modules, functionalities, and/or similar words used herein interchangeably. For example, the mobile computing entity 105 may include outdoor positioning aspects, such as a location module adapted to acquire, for example, latitude, longitude, altitude, geocode, course, direction, heading, speed, UTC, date, and/or various other information/data. In one embodiment, the location module can acquire data, sometimes known as ephemeris data, by identifying the number of satellites in view and the relative positions of those satellites. The satellites may be a variety of different satellites, including LEO satellite systems, DOD satellite systems, the European Union Galileo positioning systems, GLONASS, the Chinese Compass navigation systems, Indian Regional Navigational satellite systems, and/or the like. Additionally, the location module may be compatible with A-GPS for quick time to first fix and jump starting the ability of the location module to acquire location almanac and ephemeris data, and/or be compatible with SBAS such as WAAS, EGNOS, MS AS, and/or GAGN to increase GPS accuracy.

For instance, such technologies may include iBeacons, Gimbal proximity beacons, BLE receivers and/or transmitters, NFC receivers and/or transmitters, and/or the like. These indoor positioning aspects can be used in a variety of settings to determine the location of someone or something to within inches or centimeters. The mobile computing entity 105 may also comprise a user interface (that can include a display 416 coupled to a processing element 408) and/or a user input interface (coupled to a processing element 408). For example, the user interface may be an application, browser, user interface, dashboard, webpage, and/or similar words used herein interchangeably executing on and/or accessible via the mobile computing entity 105 to interact with and/or cause display of information. The user input interface can comprise any of a number of devices allowing the mobile computing entity 105 to receive data, such as a keypad 418 (hard or soft), a touch display, voice/speech or motion interfaces, scanners, readers, or other input device. In embodiments including a keypad 418, the keypad 418 can include (or cause display of) the conventional numeric (0-9) and related keys (#, *), and other keys used for operating the mobile computing entity 105 and may include a full set of alphabetic keys or set of keys that may be activated to provide a full set of alphanumeric keys. In addition to providing input, the user input interface can be used, for example, to activate or deactivate certain functions, such as screen savers and/or sleep modes. Through such inputs the mobile computing entity can collect contextual information/data as part of the telematics data.

The mobile computing entity 105 can also include volatile storage or memory 422 and/or non- volatile storage or memory 424, which can be embedded and/or may be removable.

Exemplary User Computing Entity

In one embodiment, the user computing entities 140 may each include one or more components that are functionally similar to those of the tracking computing entity 110 and/or the mobile computing entity 105.

These architectures are provided for exemplary purposes only and are not limiting to the various embodiments. III. Exemplary System Operation

Reference will now be made to Figure 5. Figure 5 is a flowchart illustrating operations and processes that can be used in accordance with various embodiments of the present invention. Brief Overview

Described herein are embodiments for a flight-safe container (and/or other asset) tracking that allows tracking using beacons. In one embodiment, a container beacon 155 associated with a container 107 can support enablement of a flight-safe operational mode, which includes stopping the advertising operation of the container beacon 155 and keeping the container beacon 155 in the listening mode or the sleep mode as necessary (e.g., after being loaded onto a plane). After being unloaded from the plane, the container beacon 155 associated with the container 107 can receive one or more trigger signals to enable its advertising mode. The container beacon 155 can then transmit one or more signals to a powered asset beacon 150 associated with a powered asset 100, for example, to enable location tracking using Bluetooth Low Energy Beacons for the corresponding container 107.

In one embodiment, before the plane loaded with the container 107 starts to move, a flight-safe operational mode of the container beacon 155 associated with the container 107 may be enabled. The following operations/steps describe an exemplary enablement of a flight-safe operational mode. The enablement may be achieved by setting the listening mode as the default operational mode of the container beacon 155 associated with the container 107. Thus, for instance, after losing connection with a powered asset beacon 150 (or some other entity), the container beacon 155 may automatically stop the advertising mode and enter into the listening mode. Alternatively, the container beacon 155 can receive one or more trigger signals to stop the advertising mode and enable the listening mode or sleep mode. The one or more trigger signals can be transmitted from a device affixed to the plane, a device that is local to the corresponding plane location, or a device that is remotely located. The one or more trigger signals may be transmitted constantly, and/or periodically, such that the container beacons 155 may periodically or continuously receive the trigger signals to maintain the sleep mode of the container beacons 155 during flight.

In one embodiment, the container beacon 155 may switch/change modes from the listening mode to the power-saving sleep mode upon detecting the occurrence of one or more configurable triggers/events. The configurable triggers/events may be a value, a change, and/or a rate of change, of pressure, altitude, motion, light, combinations thereof, and/or the like; a location; a sound, a time; one or more sleep signals transmitted from another beacon (or other appropriate computing entity, such as a beacon secured within an aircraft); a switch; a button; and/or the like. The configurable triggers/events may be preconfigured, determined adaptively by the container beacon 155 associated with the container 107, transmitted from another beacon, and/or the like. For example, the container beacon 155 can enter into the sleep mode upon detecting that the altitude of the plane loaded with the container 107 has reached a configurable threshold, upon detecting that the container beacon 155 is inside or outside of one or more configurable geo-fences, upon detecting a unique sound signature (e.g., via a sound sensor) indicating the engaging of floor latch securing hardware, upon detecting the presence of a group of beacons exceeding a configurable threshold, upon detecting an elapsed period of time without receiving a signal, or after not having been moved for a configurable period of time. Alternatively, the container beacon 155 associated with the container 107 may switch/change from the listening mode to the sleep mode upon receiving one or more sleep trigger signals transmitted from an appropriate computing entity. For example, the container beacon 155 may enter a sleep mode for a fixed period of time upon receipt of a sleep trigger signal (e.g., a message) causing the container beacon 155 to enter the sleep mode. Accordingly, the container beacon 155 may periodically "wake-up" (switch from the sleep mode into an active mode) into a listening mode to determine whether the sleep trigger signals are still being broadcast. Upon determining that another sleep trigger signal is received, the container beacon 155 may reenter the sleep mode until such a time that the container beacon 155 wakes up and no sleep trigger signal is detected.

In one embodiment, the container beacon 155 may switch/change modes from the sleep mode to the listening mode upon detecting the occurrence of one or more configurable triggers/events. The configurable triggers/events may be a value, a change, and/or a rate of change, of pressure, altitude, motion, light, combinations thereof, and/or the like; a location, a sound, a time; one or more wake signals transmitted from another beacon (or other appropriate computing entity, such as a beacon secured within an aircraft); a switch; a button; and/or the like. As previously noted, the configurable triggers/events may be preconfigured, determined adaptively by the container beacon 155 associated with the container 107, transmitted from another beacon, and/or the like. For example, the container beacon 155 can enter into the listening mode upon detecting that the altitude of the plane loaded with the container 107 has reached a configurable threshold value, or determining a plane landing motion by detecting change of velocity, acceleration, altitude, combinations thereof, and/or the like. Alternatively, the container beacon 155 associated with the container 107 may switch/change from the sleep mode to the listening mode upon receiving one or more wake trigger signals transmitted from an appropriate computing entity.

In one embodiment, after being unloaded from the plane, the container beacon 155 may switch/change from the listening mode to the advertising mode upon detecting the occurrence of one or more configurable triggers/events. In another embodiment, the one or more wake trigger signals may be signals transmitted from a powered asset beacon 150 associated with a powered asset 100 (or any other computing entity, such as a device affixed to the plane).

In one embodiment, the container 107 is loaded to a non-powered asset 103 that is to be moved by a powered asset 100 (e.g., see Figure 1). The container beacon 155 associated with the container 107 may receive one or more signals transmitted from a powered asset beacon 150 associated with the powered asset 100. The one or more signals transmitted by the powered asset beacon 150 may include a unique identifier (e.g., GUID, UUID, and/or the like). The container beacon 155 may, upon verifying that the received identifier is one that it should respond to, generate and transmit one or more signals, which may include the unique identifier, received signal strength indicator (RSSI), and/or other information/data. The powered asset beacon 150 may, upon receiving the one or more signals transmitted by the container beacon 155, identify and register the container 107 and transmit one or more confirmation signals. The container beacon 155 may then enter into the advertising mode.

In one embodiment, the powered asset beacon 150 (with which the container beacon 155 associated with the container 107 is registered) may transmit one or more signals to an appropriate computing entity (e.g., a mobile computing entity, a tracking computing entity) to associate the container 107 with the powered asset 100, and/or update the location of the container 107 as being the location of the powered asset 100 regularly, periodically, continuously, during certain time periods or time frames, upon determining the occurrence of one or more configurable triggers/events, in response to requests, in response to determinations/identifications, combinations thereof, and/or the like.

In one embodiment, the powered asset beacon 150 associated with the powered asset

100 may, upon detecting the connection/communication loss with the container beacon 155 associated with the container 107, deregister the container 107, and/or transmit one or more signals to the appropriate computing entity to de-associate the container 107 with the powered asset 100. The appropriate computing entity may record the last known container location and stop tracking the container 107 location via the powered asset's 100 location.

In one embodiment, the container beacon 155 associated with the container 107 may, upon detecting the connection/communication loss with the powered asset beacon 150 associated with the powered asset 100, switch/change to the listening mode. Alternatively, the container beacon 155 associated with the container 107 may maintain the advertising mode, upon detecting the connection/communication loss with the powered asset beacon 150 associated with the powered asset 100, until receiving one or more other trigger signals. As will be recognized, a variety of approaches and techniques can be used to adapt to various needs and circumstances. Operation/Step 1 of Figure 5: Generate and Transmit Signals

In one embodiment, the process may begin with a powered asset beacon 150 associated with a powered asset 100 transmitting one or more signals for use by a container beacon 155 associated with a container 107. As shown in Figure 6, which shows a schematic view of a powered asset 100 transporting a plurality of non-powered assets 103 and containers 107, the powered asset beacon 150 may transmit one or more signals (e.g., registration/confirmation signals, discussed in greater detail herein) within a communication range 150a to be received by various container beacons 155 located within the communication range 150a (e.g., container beacons associated with containers A and B). To avoid undesirably linking containers 107 that are not being transported by the powered asset 100 (e.g., container C, shown in Figure 6), the communication range 150a may be configured to encompass an area around the powered asset 100 in which transported containers 107 are expected to be located (e.g., behind and/or on the powered asset). Certain embodiments may be configured to simply locate various containers however, regardless of whether those containers are connected to the powered asset 100. In such embodiments, the communication range 150a of a powered asset beacon may be generally circular surrounding the powered asset beacon 155, and may encompass areas beyond where a particular container 107 may be pulled and/or associated with the powered asset. The powered asset beacon 150 may transmit the one or more signals regularly, periodically, continuously, during certain time periods or time frames, on certain days, upon determining the occurrence of one or more configurable triggers/events, in response to requests, in response to determinations/identifications, combinations thereof, and/or the like. As previously noted, the one or more signals transmitted by the powered asset beacon 150 may include one or more unique identifiers. The unique identifiers may identify the relevance of the powered asset beacon 150 (and corresponding powered asset 100) to the container beacons 155 within range. For instance, the one or more signals may include a powered asset identifier and/or a powered asset beacon identifier (e.g., powered asset information/data).

As an alternative, the process may begin with an appropriate computing entity (e.g., an information/data collection device 130, a mobile computing entity 105, a powered asset computing entity, and/or the like) transmitting one or more signals for use by container beacons 155 within range. As yet another alternative, the process may begin with a device affixed to a plane, or a device that is local to the corresponding plane location, transmitting one or more signals for use by a container beacon 155 associated with a container 107 being unloaded from the plane. As will be recognized, a variety of other approaches and technique can be used to adapt to various needs and circumstances.

Operation/Step 2 of Figure 5: Listening Mode: Receive Signals

In one embodiment, a container beacon 155 can have a preconfigured interest in powered asset beacon 150 signals of a particular class/type and/or appropriate computing entity signals of a particular class/type. The signals may include one or more unique identifiers that uniquely identify the corresponding powered asset 100 and/or powered asset beacon 150 (e.g., powered asset information/data). Using this approach, in listening mode, the container beacon 155 can ignore all powered asset beacon 150 signals and/or computing entity signals for which it is not registered. Similarly, the container beacon 155 can respond to a number of different types of powered asset beacon signals and/or computing entity signals.

Accordingly, as shown in Figure 6, each of the container beacons 155 associated with containers A, B, and C may be in listening mode, until detecting the presence of a powered asset beacon 150 as discussed in greater detail herein. As an example, the container beacons 155 associated with containers A and B were in listening mode until receiving one or more signals from the powered asset beacon 150, and then the container beacons 155 associated with containers A and B entered advertising mode, as discussed herein. However, because the container beacon 155 associated with container C is not within a communication range of the powered asset beacon 150, the container beacon associated with container C remains in listening mode.

Operations/Steps 3 and 4 of Figure 5: Generate, Transmit and Receive Signals

In one embodiment, after receiving one or more signals from a powered asset beacon 150 of a particular class/type (e.g., a powered asset beacon 150 for which the container beacon 155 has a preconfigured interest), the container beacon 155 may generate and transmit one or more signals for the powered asset beacon 150 to detect and process, as illustrated in Figure 6. For example, the powered asset beacon 150 (or a plurality of powered asset beacons 150 associated with a single powered asset 100) may detect the presence of the container beacon 155 using one or more methodologies described in U.S. Patent No. 9,658,310, which is incorporated herein by reference in its entirety. The one or more signals (e.g., advertising signals) from the container beacon 155 may include the powered asset's unique identifier, the powered asset beacon's unique identifier, the container's unique identifier, the container beacon's unique identifier, RSSI, and/or other information/data. Moreover, the powered asset beacon 150 may be configured to detect and monitor the strength of the received signal, and may be configured to compare the actual received signal strength against an expected signal strength as indicated by the RSSI data, and may utilize the determined difference between the actual and expected signal strength to estimate a distance between the powered asset beacon 150 and the container beacon 155. In one embodiment, the container's information/data (e.g., unique container identifier and/or unique container beacon identifier) may identify relevance of the container beacon 155 to the powered asset beacon 150 (and/or the appropriate computing entity). Thus, the powered asset beacon 150 may receive the one or more signals transmitted from the container beacon 155 with the container information/data.

In certain embodiments, the container's information/data as transmitted by the container beacon 155 may be detected by a plurality of powered asset beacons 150 (e.g., disposed on a respective plurality of powered assets 100). Each of the plurality of powered asset beacons 150 detecting the presence of the container beacon 155 may monitor various aspects of the received signal, such as the RSSI data, the detected signal strength, and/or the like to ascertain an estimated distance between the container beacon 155 and each powered asset beacon 150. Each powered asset beacon 150 (and/or another computing entity, such as the tracking computing entity 110) may compare the estimated distance between the powered asset beacons 150 and the container beacons 155 to triangulate the estimated location of the container 107, relative to the known locations of the powered assets 100 (e.g., as determined based at least in part on location sensors disposed on each powered asset 100).

Moreover, in embodiments in which the powered asset beacons 150 contain and/or are associated with cameras having known orientations relative to the powered asset beacons 150, the powered asset beacons may be configured to identify an estimated location of a detected container 107 that is visible within an FOV of the camera to augment and/or improve the accuracy of a determined location of a container 107 as determined based at least in part on the wireless information/data received from the container beacon 155. For example, the powered asset beacons 150 may be configured to ascertain an estimated distance between the powered asset beacons 150 and a detected container beacon 155 based at least in part on a comparison between the RSSI data and an actual detected signal strength. Moreover, upon detecting the container within an FOV of the camera (e.g., utilizing OCR to recognize container identifiers printed or otherwise disposed on a side of the container), the powered asset beacon 150 (and/or another computing entity, such as the tracking computing entity 110), may be configured to identify the location of the powered asset 100 and the orientation of the FOV of the camera disposed on the powered asset 100. Based on the known location of the powered asset 100 and orientation of the camera on the powered asset 100, the powered asset beacon 150 (and/or another computing entity, such as the tracking computing entity 110) may be configured to determine a relative orientation of the container 107 relative to the powered asset 100. Based at least in part on the known location of the powered asset 100, the known orientation of the camera, and the estimated distance between the powered asset beacon 150 and the container beacon 155, the powered asset beacon 150 (and/or another computing entity, such as the tracking computing entity 110) may be configured to determine an estimated location of the container 107. As a specific example with reference to Figure 8 (which illustrates a schematic diagram of a located container 107 relative to a powered asset 100), the location of the container 107 may be estimated based on a known location of a single powered asset 100. The powered asset 100 may have a known location and heading, and the orientation of the FOV of the camera of the powered asset beacon 150 may be known to be directly opposite of the heading of the powered asset 100. In the embodiment of Figure 8, the container beacon 155 may transmit container information/data to the powered asset beacon 150, including RSSI data. Based at least in part on the RSSI data and the detected signal strength received from the container beacon 155, the powered asset beacon 150 may estimate a distance between the powered asset beacon 150 and the container beacon 155. Moreover, because the container is located within the FOV of the camera of the powered asset beacon 150, the powered asset beacon 150 may be configured to identify the container based on the identifying information (indicated by the "A" on the container 107), and may determine an estimated location of the container 107 as being the estimated distance away from the powered asset beacon 150, and being located in the direction of the FOV of the camera of the powered asset beacon 150.

In certain embodiments, the wireless information/data collected by the powered asset beacon 150 (e.g., signals received from the container beacons 155) may be utilized to augment and/or improve the OCR process for recognizing information/data via the camera. For example, the wireless information/data may limit the possible data matches that may be utilized to ascertain the identity of identifying information viewable with the FOV of the camera. In certain embodiments, the powered asset beacon 150 may be configured to apply OCR concepts to determine that any viewable identifying information/data within the FOV of the camera must match identifying information of container 107 detected via wireless transmissions received by the powered asset beacon 150. As a specific example, the powered asset beacon 150 may detect wireless signals transmitted by container beacons 155 associated with containers 123ABC, 456DEF, and 789GHI. Therefore, upon identifying a container 107 within the FOV of the camera, the powered asset beacon 150 may be configured to compare the identifying information on the container 107 against each of character strings "123 ABC," "456DEF," and "789GHI" to identify which of these character strings most closely resembles the identifying information/data on the container 107.

Moreover, in certain embodiments, the identifying information/data received via the camera of the powered asset beacon 150 (e.g., via OCR) may be utilized to augment and/or improve the information/data received wirelessly via the powered asset beacon 150 from the one or more container beacons 155. In certain embodiments, the powered asset beacon 150 may be configured to link or otherwise associate the powered asset 100 with a particular container 107 only if the container 107 is visible within the FOV of the camera. In such embodiments, if wireless information/data is detected from other container beacons 155, the powered asset beacon 150 may not associate with those other container beacons 155. Operation/Step 5 of Figure 5: Identify and Register the Container, and/or Transmit New Registration

In one embodiment, after receiving the one or more signals in operation/step 4, the powered asset beacon 150 may register the container 107 using the container's information/data (e.g., unique container identifier and/or unique container beacon identifier) transmitted by the container beacon 155. In one embodiment, the powered asset beacon 150 (or other computing entity) may further transmit the one or more new container registration signals to an appropriate computing entity to initiate the process of associating the container 107 with the powered asset 100, such as to a tracking computing entity 105. The one or more transmitted registration signals may include the container information/data, the powered asset information/data, and/or the like. The communication between the powered asset beacon 150 and the appropriate computing entity may be executed using a wired connection, for example, a bus, a wired PAN, or the like, or via wireless communication networks, for example, a wireless PAN, LAN, MAN, WAN, and/or the like. As an alternative embodiment, the function of associating the container 107 with the powered asset 100 may be executed by the powered asset beacon 150.

Operations/Steps 6, 7, and 8 of Figure 5: Send and Receive Confirmation, and Enter Advertising Mode

In one embodiment, the powered asset beacon 150 (or other appropriate computing entity) may send one or more confirmation signals to the container beacon 155 to inform the container beacon 155 of a positive identification and registration of the corresponding container 107. Responsive to receiving the one or more confirmation signals, the container beacon 155 may enter advertising mode. In advertising mode, the container beacon 155 may regularly, periodically, and/or continuously transmit one or more advertising signals (as illustrated in Figure 6) for use by the powered asset beacon 150 and/or the appropriate computing entity to track its location. To do so, the one or more advertising signals may include the container information/data (e.g., unique container identifier and/or unique container beacon identifier), RSSI, and/or other information/data.

In one embodiment, if the container beacon 155 associated with the container 107 determines/detects that it is no longer in communication with the powered asset beacon 150, the container beacon 155 may switch/change from the advertising mode to the listening mode. Similarly, if the container beacon 155 determines/detects that it is still in communication with the powered asset beacon 150, the container beacon 155 may continue advertising in advertising mode. In certain embodiments, the container beacon 155 may periodically enter listening mode for a brief period of time while in advertising mode to determine whether the container beacon 155 remains in connection with one or more powered asset beacons 150. For example, while in listening mode, the container beacon 155 may determine whether the container beacon 155 detects transmissions emitted by the powered asset beacon 150. Upon determining that the container beacon 150 detects transmissions emitted by the powered asset beacon 150, the container beacon 155 may reenter advertising mode to continue broadcasting container information/data to the powered asset beacon 150. However, upon determining that the container beacon 155 does not detect signals emitted by the powered asset beacon 150 while in listening mode, the container beacon 155 may remain in listening mode until a signal emitted from a powered asset beacon 150 is detected.

Operations/Steps 9, 10, 11, and 12 of Figure 5: Associate and Track Container with Powered Asset

In one embodiment, the mobile computing entity 105 (or other appropriate computing entity) may associate the container 107 with the powered asset 100 upon receiving the one or more container 107 registration signals from the powered asset beacon 150. In one embodiment, to track the container 107, the mobile computing entity 105 may generate and transmit one or more signals to the tracking computing entity 110 to initiate the process of tracking the container 107 and/or update the location of the container 107 as being the location of the corresponding powered asset 100. The one or more transmitted signals may include the powered asset information, container information/data of the newly registered container 107, a timestamp for initiating the association of the container 107 with the powered asset 100, and location information/data of the powered asset 100. The location information/data of the powered asset 100 (and thereby the container 107) may be identified/determined using GPS technologies by acquiring, for example, latitude, longitude, altitude, and/or geocode data corresponding to workers/users. Additionally or alternatively, the location information/data may be collected and provided via triangulation of various communication points (e.g., cellular towers, Wi-Fi access points, etc.) positioned at locations throughout a geographic area. Such embodiments allow the location and/or movement of powered assets 100 and associated containers 107 to be monitored and tracked. As will be recognized, a variety of other approaches and techniques can be used to adapt to various needs and circumstances. The location of each of these can be updated and stored in a tracking database, for example, by the tracking computing entity 110. The location of the powered assets 100 and containers 107 can be monitored, tracked, and updated regularly, periodically, continuously, upon determining the occurrence of one or more configurable triggers/events, and/or the like.

Operation/Step 13 of Figure 5: Receive Signals

In one embodiment, the powered asset beacon 150 may receive one or more signals transmitted by a container beacon 155 in advertising mode to confirm that the container beacon 155 is within communication range and has normal connection with the powered asset beacon 150. This validates the continuing association of the container 107 with the powered asset 100, which indicates no action is needed to de-associate the container 107 with the powered asset 100. And as noted, the location of the powered assets 100 and containers 107 can be updated regularly, periodically, continuously, upon determining the occurrence of one or more configurable triggers/events, and/or the like. As will be recognized, these steps/operations can be performed by a variety of computing entities. The location of the containers 107 relative to the powered assets 100 may be determined and/or updated periodically based on the detected signal strength of the signal emitted by a container beacon 155 and received by a powered asset beacon 150 (e.g., compared against an emitted signal strength, as indicated in the RSSI data).

As discussed herein, the powered asset beacon 150 may continuously or periodically transmit one or more signals to the associated container beacons 155. As discussed below, the container beacons 155 may be configured to continuously and/or periodically monitor the connection with the powered asset beacon 150 (e.g., by periodically switching into listening mode), based at least in part on one or more detected signals transmitted from the powered asset beacon 150. Upon determining that no powered asset beacon 150 signals are detected, the container beacons 155 may be configured to switch from an advertising mode to a listening mode to conserve power. Thus, to ensure continued communication between the container beacons 155 and the powered asset beacons 150 (and vice versa), the powered asset beacons 150 may transmit one or more signals to be received by the associated container beacons 155.

In certain embodiments, the container beacons 155 may be wirelessly connected with a plurality of powered asset beacons 150 simultaneously. As the container beacons 155 broadcast container information/data while in advertising mode, a plurality of powered asset beacons 150 may receive the broadcast container information/data, and may monitor various aspects of the container beacon 155 based on the received container information/data. For example, each of a plurality of powered asset beacons 150 may receive the container information/data, and may determine a relative location of the powered asset beacon 150 relative to the container 107 (e.g., based on the received signal strength and/or the RSSI data broadcast by the container beacon 155). In certain embodiments, the location of each of the plurality of powered asset beacons 150 are known (e.g., based on location devices on each of the powered assets), and accordingly an estimated location of the container 107 may be determined by triangulation, utilizing the determined distances between the container 107 and each of the plurality of powered assets. For example, each of the plurality of powered asset beacons 150 may transmit container information/data including the determined distance between the container and the powered asset, to tracking computing entity, which may utilized the determined distances detected by a plurality of powered asset beacons 150 to triangulate the location of the container 107. Operation/Step 14 of Figure 5: Receive Trigger Signals and/or Enter Listening Mode

In one embodiment, a container beacon 155 may switch/change to the listening mode from the advertising mode upon determining the occurrence of one or more configurable triggers/events. As previously described, the configurable triggers/events may be a value, a change, and/or a rate of change, of pressure, altitude, motion, light, combinations thereof, and/or the like; a location, a sound, a time; one or more signals transmitted from another beacon (or other appropriate computing entity; a switch; a button; and/or the like). The configurable triggers/events may be preconfigured, determined adaptively by the container beacon 155 associated with the container 107, transmitted from another beacon, and/or the like. For example, in one embodiment, the container beacon 155 may, while in the advertising mode, enable the listening mode during certain time periods or time frames to detect if the container beacon 155 is in normal communication with a powered asset beacon 150 associated with a powered asset 100 (and/or another appropriate computing entity). The container beacon 155 may switch/change into the listening mode, and stop advertising if necessary, upon detecting that the container beacon 155 is no longer in communication with the powered asset beacon 150 (and/or another appropriate computing entity). Alternatively, the container beacon 155 may switch/change into the listening mode and stop advertising upon receiving one or more trigger signals transmitted from a device (or other appropriate computing entity) affixed to a plane, local to the corresponding plane location, or remotely located. Operations/Steps 15 and 16 of Figure 5: Receive Trigger Signals and/or Change Mode

In one embodiment, a container beacon 155 may switch/change from the listening mode to the sleep mode to save energy upon determining the occurrence of one or more configurable triggers/events. In an alternative embodiment, a container beacon 155 may switch/change directly from the advertising mode to the sleep mode to save energy upon determining the occurrence of one or more configurable triggers/events. For example, as shown in Figure 7,, the container beacon 155 may switch/change from the listening mode to the sleep mode upon detecting that a plane (in which the container 107 is loaded) has reached/exceeded a configurable altitude threshold and/or detecting a predefined motion event. In the illustrated embodiment of Figure 7, the container beacons 155 associated with each of containers D and E remain below the altitude threshold, and therefore the container beacons 155 associated with containers D and E remain active. Specifically, the container beacon 155 associated with container D may be in advertising mode, because the container beacon 155 is located within the transmission range 150a associated with the powered asset beacon 150, and the container beacon 155 associated with container E is in listening mode. Container F shown in Figure 7 is being transported by plane, and is located above the altitude threshold. Accordingly, the container beacon 155 associated with container F is in sleep mode and may remain in sleep mode until the container beacon 155 determines that it is located below the altitude threshold.

Alternatively, the container beacon 155 may enter into the sleep mode upon detecting that, for a configurable period of time, the container 107 has not been moved and/or the container beacon 155 has not been in communication with a powered asset beacon 150 for a configurable period of time. As will be recognized, a variety of other approaches and techniques can be used to adapt to various needs and circumstances.

As yet another example, the container beacon 155 may enter into the sleep mode upon receiving a trigger signal, for example, transmitted from a beacon located within an aircraft. The container beacon 155 may be configured to enter the sleep mode for a period of time upon detecting the trigger signal, and may be configured to awaken at the end of the period of time. Upon awakening, the container beacon 155 may monitor for one or more additional sleep mode trigger signals which, if received, cause the container beacon 155 to reenter the sleep mode for a period of time. In certain embodiments, the period of time may be predetermined (e.g., 1 minute, 15 minutes, 1 hour, and/or the like), or the period of time may be defined as a part of the data transmitted within the sleep mode trigger signal. For example, in the latter embodiment, the sleep mode trigger signal may comprise data identifying a period of time for the container beacon 155 to remain asleep (e.g., a period of time at least substantially equal to the expected length of a flight).

Similarly, the container beacon 155 may switch/change from the sleep mode to the listening mode upon determining the occurrence of one or more configurable triggers/events. For example, in one embodiment, the container beacon 155 may switch/change from the sleep mode to the listening mode upon detecting a plane, in which the container 107 is loaded, reaches a configurable altitude (e.g., ground level) and/or detecting a predefined motion event. Alternatively, the container beacon 155 may enter into the listening mode upon receiving one or more trigger signals transmitted from a device (or other appropriate computing entity) affixed to a plane, local to the corresponding plane location, or remotely located.

Operations/Steps 17 and 18 of Figure 5: Lose Connection and Deregister Container

In one embodiment, a powered asset beacon 150 may detect the connection/communication loss with a container beacon 155 with which it is registered. In response, the powered asset beacon 150 (or other appropriate computing entity) may initiate the process to deregister the container 107 from the corresponding powered asset 100. Alternatively, a powered asset beacon 150 (or other appropriate computing entity) may generate and transmit one or more request signals to a registered container beacon 155 upon detecting the connection/communication loss with the container beacon 155. The one or more request signals may include triggers for the container beacon 155 to (a) switch/change to the advertising mode from the listening mode and/or the sleep mode and/or (b) request one or more advertising signals from the container beacon 155. If the powered asset beacon 150 (or other appropriate computing entity) does not receive a response from the container beacon 155 after one or multiple attempts to establish the connection, the powered asset beacon 150 (or other appropriate computing entity) may confirm the loss of connection with the container beacon 155 and/or initiate the process to deregister the container 107 accordingly.

After deregistering a container 107, the powered asset beacon 150 (or other appropriate computing entity) may transmit a request to de-associate the container 107 with the powered asset 100. In one embodiment, the request to de-associate the container 107 may include a timestamp with location information/data for the last normal communication between the container beacon 155 and the powered asset beacon 150 (or other appropriate computing entity). Operations/Steps 19, 20, and 21 of Figure 5: De-Associate the Container with the Powered Asset

In one embodiment, responsive to an appropriate request, a container 107 may be de-associated with the powered asset 100 with which the container 107 was previously associated. In one embodiment, the de-association may include transmitting a request to tracking computing entity 110 to stop updating the container's 107 location as being the location of the previously associated powered asset 100. Correspondingly, the tracking computing entity 110 may record the last known container 107 location in the tracking database as being the location for the last normal communication between the container beacon 155 and the powered asset beacon 150 (or other appropriate computing entity). The appropriate computing entity records this location as the container 107 location until one or more new valid update signals are received for the container. For instance, the one or more new update signals may be requests to initiate location tracking of the container 107 via a powered asset 100 (or other appropriate computing entity), one or more signals informing that the container 107 is loaded onto a plane or moved into a warehouse, a scan or other reading of the container information/data at one or more points in the carrier' s transportation and logistics network, and/or the like.
