DURING A SPORTING EVENT

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of priority of U.S. provisional patent application no. 63/222,715 titled “IMPROVED METHODS, DEVICES, AND SYSTEMS FOR FACILITATING OFFICIALS DURING A SPORTING EVENT,” filed July 16, 2021, which is incorporated herein by its entirety by this reference

TECHNICAL FIELD

[0002] The present invention relates to a mobile device and more specifically to methods, devices, and systems for facilitating officials during a sporting event.

BACKGROUND

[0003] A key requirement in officiating sporting events (e.g. basketball games, etc.) is providing accurate and fair timekeeping. Timekeepers have to listen carefully for an on court referee whistle blow and as quickly as possible have to stop the game clock. Additionally, they have to watch for the indication from the referee to start the game clock. Any delay and/or failure to accurately stop or start the game clock requires game delay for the timekeeper to rewind the game clock to the correct setting. Such errors further delay the game and cause players, coaches, and fans much concern while putting uncertainty into the overall outcome of the game.

[0004] Accordingly, a need exists to better facilitate officials during sporting events including accurate and fair timekeeping.

[0062] FIG. 1 depicts a diagram illustrating a system 100 for facilitating a plurality of referees during a sporting event (e.g. a basketball game) in accordance with embodiments of the present disclosure. A basketball court 102 is depicted with mobile devices 104 A - 104C (e.g. belt packs) that may be carried on the waist bands or belts of three referees (not shown is FIG. 1). The mobile devices 104 A - 104C communicate over radio frequency (RF) wireless links with an access point 106. The access point 106 is electrically coupled with a scoreboard control console 108. A scoreboard 110 is either electrically coupled or wirelessly coupled with the scoreboard control console 108. The scoreboard control console 108 may be an OES control console, a Daktronics control console, or the like.

[0063] The access point 106 utilizes a DIN connector with unique cables to interface with specific wiring and connector interfaces for different manufacturers’ control consoles (e.g. an XLR for the OES control consoles and an RJ11 for the Daktronics control consoles). The input and output communications between the access point 106 and scoreboard control console 108 include isolated switched state (dry contact) signals. The access point 106 has an input port requiring remote dry contact control that can be programmatically defined to accommodate features supported by various scoreboard consoles (e.g. the scoreboard control console 108 may output a state change when the clock reaches zero). The access point 106 supports the ability to program and map input and output connections for specific functions and wiring configurations.

[0064] The mobile devices 104A - 104C can each detect a whistle blow and/or button events initiated by the referees, and immediately send a message to the access point 106. The access point 106 receives the message, decodes the message, and activates the remote input of the scoreboard control console 108 to either start or stop the clock. The access point 106 also sends the mobile devices 104A - 104C an acknowledgement that the message was successfully received. The mobile devices 104 A - 104C use the acknowledgement to drive a haptic vibration motor alerting the referee that the start or stop event was successful. The entire transaction typically takes place in less than 50 milliseconds (mS). This response time is typically faster and more consistent than a human’ s reaction at the scoreboard control console 108.

[0065] The RF wireless links operate over a 902 mega-Hertz (MHz) to 928 MHz frequency band, which is outside the more used Bluetooth® and Wi-Fi frequency bands. The 902 MHz to 928 MHz frequency band provides excellent range and propagation characteristics as compared to the Bluetooth® and Wi-Fi frequency bands. The RF wireless links specifically use Wide-band Direct Sequence Spread Spectrum (WBDSSS) technology to minimize interference on a given link channel. Data for each RF wireless link of the mobile devices 104A - 104C is spread across five channels each having a 200 kilo-Hertz (kHz) spacing (i.e. providing a 1 MHz wide effective channel). There are a total of 123 available channels with center frequencies of each 1 MHz effective channel on channels 3, 8, 13, ... 123 (i.e. 902.8 MHz, 903.8 MHz , 904.8 MHz, ... 926.8 MHz). The RF wireless links are each wide-band half-duplex spread spectrum. In some embodiments, frequency hopping may be employed for the RF wireless links.

[0066] The access point 106 may also sample a local RF spectrum at the basketball court 102 for interference and dynamically select the best channels for device commissioning and operation of the mobile devices 104A - 104C. In some embodiments, RF mitigation steps such as separating the proximity of the mobile devices 104A - 104C and the access point 106 may be required.

[0067] The mobile devices 104A - 104C and the access point 106 may each transmit up to a power level of +10 decibel-milliwatts (dBm) with a receiver sensitivity of -110 dBm yielding a received signal strength indicator (RSSI) dynamic range of 95dB. This provides much overhead for blockage of any of the RF wireless signals due to the bodies of players and/or referees. The mobile devices 104A - 104C each include a helical printed circuit board (PCB) antenna. The access point 106 includes an external one half wave dipole antenna. Additionally, WBDSSS modulation enables Forward Error Correction (FEC) using K=4 as the constraint length in a convolutional encoder.

[0068] To minimize power consumption and prolong battery life, the mobile devices 104A - 104C operate in a non-beacon mode and each generate a status/keep-alive message at a programmable interval. The status/keep-alive messages contain statistics associated with the mobile devices 104A - 104C including their battery status. During network establishment, each of the mobile devices 104A - 104C scan for incoming messages from the access point 106 at approximately 500 mS intervals to service key regeneration commands, over the air download commands, and remote configuration or control commands. This scan interval is also configurable.

[0069] Each of the mobile devices 104A - 104C has a unique identifier (ID) in the form of a six-byte media access control (MAC) address and a configurable four-byte serial number. Up to fifty mobile devices may be supported by the access point 106. However, the access point 106 is typically configured to handle only four mobile devices per network session (i.e. game) as a default.

[0070] The network is compliant to the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard defining the MAC layer protocol.

[0071] Advanced Encryption Standard (AES) 128 encryption/decryption is used for the data at the MAC layer. The mobile devices 104A - 104C and the access point 106 use secure commissioning with shared secret network keys for initial pairing (AES-CMAC). Unique dynamic device keys are generated using Elliptic Curve Diffie Heilman (ECDH) p256 during commissioning for run-time data exchange. The access point 106 communicates only with mobile devices with the shared secret key, and only accepts data that is encrypted with the dynamic device keys. The access point 106 controls both the generation and the storage of the dynamic device keys. Additional security is provided by limiting the number of associated mobile devices active during the network session (e.g. four devices - mobile devices 104A - 104C and one spare mobile device). This number is also configurable.

[0072] All communications between the mobile devices 104A - 104C and the access point 106 are acknowledged by a return message/packet. The system 100 is further configured to detect a whistle blow and/or button depress, and alert the scoreboard control console 108 in less than 50 mS. The mobile devices 104A - 104C are also configured to alert each other via the access point 106 and initiating via haptic feedback in less than 250 mS.

[0073] The access point 106 logs and stores data of the mobile devices 104A - 104C including timestamps, device IDs, events, and event data. For example, the event data may include when a scoreboard reaches 0:00:00 and/or game clock, period, time-outs, etc. Real time and stored data are available for Internet export. The access point 106 may be connected to the Internet via a Wi-Fi and/or Ethernet connection. Data may also be stored in the cloud in addition to a removable Secure Digital (SD) card.

[0074] Configuration data of the mobile devices 104A - 104C is available via a remote application program interface (API) while connected with the access point 106. Additionally, software within the mobile devices 104 A - 104C may be updated by the remote API.

[0075] FIG. 2 depicts a diagram 200 illustrating a side view and a front view of a mobile device 104 of FIG. 1 in accordance with embodiments of the present disclosure. The mobile device 104 includes rechargeable lithium batteries and a universal serial bus (USB) charging port. In some embodiments, the mobile device 104 may include a wireless charging port. The mobile device 104 is light weight and is configured to enter a sleep mode after approximately fifteen minutes of inactivity. The mobile device 104 is configured to save configuration data using onboard flash memory. C configuration data includes an access point ID, a network ID, frequency bands, frequency channels, serial number, and encryption/decryption keys.

[0076] The mobile device 104 also includes a display 202. Specifically, the display 202 is a color thin-film transistor (TFT) display with light emitting diode (LED) backlight supporting custom graphics. Tilt based operation further conserves battery light by dimming the display 202 when not being viewed by a referee.

[0078] The microphone 302 easily adapts to standard lanyards and is tuned to the internal detection circuits of the mobile device 104. Larger cabling and flexible insulation resists wire breakage while electrically coupling the microphone 302 to the mobile device 104. In some embodiments, a wireless microphone (not shown in FIG. 3) may be used.

[0079] The mobile device 104 is further configured to detect a whistle blow based on amplitude, frequency, and duration of a received audio signal via the microphone 302. The mobile device 104 discriminates against false triggers by near-by whistles, heavy breathing, and crowd/fan noise. A power level threshold for the microphone 302 is adjustable through field calibration. The mobile device 104 may be adaptive and automatically make adjustments based upon background noise, whistle frequency, and/or whistle intensity. The frequency range is typically set to a center frequency of 3700 Hz and a bandwidth 1000 Hz. Signal power to noise ratio (SNR) in the frequency domain at the frequencies of interest are determined using primary filters deployed to resolve a whistle from other noise sources

[0080] The mobile device 104 includes start and stop buttons with an ergonomic design providing intuitive button access while protecting against false button presses. The start and stop buttons are located on opposite planes of the mobile device 104 to eliminate incorrect presses by the user. Holding the stop button for approximately five seconds powers down the mobile device 104. Holding down the start button will power up the mobile device 104.

[0081] The mobile device 104 also includes haptic feedback technology for responding to acknowledgement packets/messages received from the access point 106. Patterns and intensity of haptic feedback are under software.

[0082] FIG. 4 depicts a diagram 400 illustrating a front view, a top view, a right side view and a left side view of the access point 106 of FIG. 1 in accordance with embodiments of the present disclosure.

Such a propagated signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.

[0098] Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.

[0099] Computer program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including object oriented and/or procedural programming languages. Programming languages may include, but are not limited to: Ruby, JavaScript, Java, Python, Ruby, PHP, C, C++, C#, Objective-C, Go, Scala, Swift, Kotlin, OCaml, or the like. The program code may execute entirely on the user’s computer, partly on the user’s computer, as a stand-alone software package, partly on the user’s computer, and partly on a remote computer or entirely on the remote computer or server. [00100] Aspects of the present invention are described in the instant specification with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams , and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions.

[00101] These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

[00102] These computer program instructions may also be stored in a computer readable medium that can direct a computer, other programmable data processing apparatus, or other devices to function in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the function/act specified in the flowchart and/or block diagram block or blocks.

[00103] The computer program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other devices to cause a series of operational steps to be performed on the computer, other programmable apparatus or other devices to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide processes for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

[00104] The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.

[00105] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Thus, for example, reference to "a user" can include a plurality of such users, and so forth. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
