DETAILED DESCRIPTION

[0043] A preferred embodiment of the present invention will be set forth in detail with reference to the drawings, in which like reference numerals refer to like elements or method steps throughout.

[0044] In one example embodiment, the present invention sets forth a device that uses a network of wireless connections in order to minimize search personnel. The device is a geo-locating wearable with improved capabilities in both reliability and accuracy and has multiple points of network connectivity and failsafes. Through the deployment of an IoT protocol and cloud network servers, along with the use of “Gateways”, the geolocation of the wearer can be obtained.

[0045] FIG. 1 shows an exploded view of one example embodiment of the tracking device of the present invention. Printed circuit boards (PCB) are used to control the device and to house the various transceivers and one or more microcontrollers. In the example of FIG. 1, two PCBs are provided, namely a core PCB 10 and a Module PCB 12. A battery or power source 14 is included to power the components. The device sits within a shell 16 enclosed with a top 18 and bottom 20, sandwiched next to the watchband 22. The arrangement of components can change as well as the size. For example, the device can be slim and/or formed within the watchband.

[0046] In an example embodiment, the enclosure of the shell 16 is achieved by shared mating surfaces with the top 18, which are fastened shut and sealed with one or more rubberized gaskets, which could provide all-weather capabilities such as resistance to water or water-proofing. The body of the shell 16 houses and protects electronic circuitries, including microcontroller(s), module(s), and power source.

[0047] In a further example embodiment, the device includes a programmed microcontroller to monitor the circuitry and power management. The microcontroller keeps the components in a state of hibernation until it receives a function command. Sample function commands include commands to wake up, collect data, transmit data, and/or return to a state of dormancy. In order to reduce the power usage, the device preferably spends the majority of time in a state of hibernation, which is an existing function of the technology.

[0048] The microcontroller is optionally programmed in order to select which components stay in hibernation at what time. For example, upon receipt of a signal containing a function command, the microcontroller will determine, based on the nature of the received signal, whether to respond using Bluetooth™, passive Wi-Fi, cellular or RF (Radio Frequency). The microcontroller can be programmed to respond via the same communication as the received signal and/or to receive a signal containing function command requiring the device to communicate over a requested communication channel.

[0049] During one form of example operation, when the device is awakened, it can send GPS coordinates through a wireless connection to a network, which is then processed in a server solution or other typical application. The GPS coordinates could consist of a small amount of raw data, such as latitude and longitude points or MGRS points. This method of relaying the wearer's location is ideal for areas where cellular coverage is not available, yet GPS/GNSS satellites are.

[0050] During a second form of example operation, if neither cellular or GPS connection can be obtained the device will still transmit a radio signal (RF) such as the kind used to send and receive data between transceivers. The radio transmission can be done simultaneously with cellular and/or GPS connection or as an alternative thereto. The strength of the received transmission can be optionally used to indicate the distance as well as the direction of the wearer. The radio signal source can be triangulated or used to follow its strength, using a gateway as a receiver to locate the wearer. An example form of a gateway could be affixed and permanent to a fixed structure, or mobile, such as in vehicles or carried by drones. One advantage of using a drone is to extend the line of sight beyond that available on the ground due to obstructions, exponentially increasing it's connection range.

[0051] FIG. 2 shows an example tracking system in accordance with one aspect of the present invention. A user 24 is attempting to locate the wearer of the tracking device who needs to be found. The three modes of communication are represented in FIG. 2 as RF 26; Bluetooth™, Wi-Fi, NFC 28; and 5G cellular 30. GPS/GNSS 32 is shown as providing the latitude and longitude location of the wearer. When a communication is received by any of the communication channels, the device replies with the location of the wearer, for example by providing the latitude and longitude. If a communication cannot be achieved by any of the three modes of communication, the device will default to a basic pulse mode, using a radio frequency ping 34, with or without location information.

[0052] FIG. 3 illustrates the use of the tracking system with various types of communication systems. A mobile gateway can be provided via a vehicle 36 or via a drone 38. If the wearer of the tracking device 43 is in a remote location away from road access, or cellular, Bluetooth or Wi-Fi communication, a mobile gateway can be used. For example, a drone 38 can be controlled via a vehicle 36 to fly over remote areas and transceive a ping or wakeup signal via RF transmission. Alternatively, if there are roads, the vehicle 36 itself can transmit a ping or wakeup signal via RF transmission while driving through the area. Other forms of communication shown include cellular 26 from cellular towers and RF 40 transmission from transceivers mounted on surrounding buildings. The application software 42 resides on a server or on the caregiver computing device so that the tracking device 43 is free from complicated software. The wakeup signal or ping is communicated through the appropriate channel (e.g. cellular, RF, Wi-Fi, Bluetooth, NFC) and the location is received by the application software 42 from the tracking device 43. The application software 42 then converts the raw data received from the tracking device 43 into a user-friendly format, e.g. by providing the user with a map or written directions pertaining to the location of the wearer. In this context, the user or caregiver is the person initiating the tracking request, while the wearer is the person wearing the tracking device 43.

[0053] In order to ensure that the wearer is wearing the device, the device can be optionally securely fastened by a band with a locking mechanism that is affixed to an extremity (e.g. the wrist or ankle) of the wearer.

[0054] In a further example embodiment, the band is designed to be cut, tear, and tamper resistant. The band is composed of high strength materials, surrounded by pliable materials, to promote both safety and comfort to the wearer. In one example, the locking mechanism is composed of one or more metals, utilizing a threaded and/or magnetic-fastened closure, which joins the open ends of the band creating a closed and locked loop. The locking mechanism of the bracelet or band in one example optionally includes a tool or device specialized for removal of the band.

[0055] The closure of the bracelet or band is optionally also a physical part of an integrated circuit that is monitored by the device. Should the band be cut or removed, for any reason other than a planned event, the device will detect this and send a notification, via wireless connection, indicating that the band has been removed. The band contains the device, thus removal of the band effectively results in removal and/or disconnection of the device from the person to be tracked.

[0056] Detection of the removal of the band and device can occur through a variety of ways. In the preferred embodiment, a strap is provided with an electric circuit which is closed upon closure of the locking mechanism. In this embodiment, breakage of the closed circuit will be detected by the microprocessor, which is programmed to send the notification in the preferred manner. Any such notification can be sent through any of the communication methods available, such as RF, cellular, WIFI, etc. The notification can be sent to a caregiver for receipt, for example, via email, text message, or any other form of audio or visual signal to alert the caregiver to the removal of the band containing the device. Any such notification can optionally include a last known location of the person wearing the device.

[0057] FIG. 4 shows an example embodiment of the band for the device. One end of the band 44 contains holes 46 which permit various sizes of attachment. The other end of the band 44 contains a hole 47 and slot 48. The first end of the band slides into the slot 48 and a lockable pin 50 is inserted into the hole 47 and lines up with the appropriate hole from the holes 46 in the first end of the band 44. A tool can optionally be used to insert and remove the pin 50. The band contains two additional mounting holes 52 for mounting the tracking device externally to the band 44. The center of the band contains a strip 54 of conductive material. The two additional mounting holes 52 go through the strip 54 of conductive material such that when the tracking device is mounted on the band 44, conductive pins, from the tracking device MCU 56, are inserted through the mounting holes 52 to create a closed circuit. If the strip 54 of conductive material is severed in any way, or if the tracking device is removed, the circuit will be broken and the tracking device will detect the broken circuit. As an alternative, the tracking device can be formed within the band 44 rather than mounted externally, in which case the tracking device will be connected to the strip 44 within the band. The exterior of the band can be provided with a rubber or aesthetically soft covering material or casing, encasing the strip 44 and optionally the tracking device within.

[0058] The battery life of the wearable device is extended due to the hibernation capability and use of low-power technologies. The simplicity of the arrangement ensures that the device does not burn excess energy, thereby conserving battery life. The microcontroller is optionally programmed to assess battery levels, in order to prioritize and select which components are utilized. Furthermore, the device purposefully does not include any fancy technological features, such as a display or extraneous sensors, in order to further preserve battery life.

[0059] An optional aesthetic covering is included, which could be functional, such as a timepiece, or decorative, such as a bracelet or piece of jewelry. Such an aesthetic covering could assist a user with any perceived stigma of wearing a tracking device, thereby increasing the probability of adherence as well as acceptance of wearing the device, without the wearer having the angst associated with self-consciousness. Furthermore, if the aesthetic covering is a timepiece, or a component requiring a battery, the timepiece or component or aesthetic covering will include a separate battery so as not to draw on the battery life of the tracking device.

[0060] Following from the above description, it should be apparent to those of ordinary skill in the art that, while the methods and apparatuses herein described constitute exemplary embodiments of the present invention, the invention described herein is not limited to any precise embodiment and that changes may be made to such embodiments without departing from the scope of the invention as defined by the claims. For example, while reference has been made to a battery throughout the application, it will be appreciated that the battery could be any suitable power source.

Likewise, it is to be understood that it is not necessary to meet any or all of the identified advantages or objects of the invention disclosed herein in order to fall within the scope of any claims, since the invention is defined by the claims and since inherent and/or unforeseen advantages of the present invention may exist even though they may not have been explicitly discussed herein.
