Description:
BACKGROUND 
       [0001]    Numerous prior attempts of location systems have been provided in the prior art. 
         [0002]    U.S. Pat. No. 6,362,778 B2 describes a system able to locate and track a user retaining a portable locator unit using numerous location technologies including Global Positioning Satellite (GPS) System and the generation of a beacon for use in pinpointing the location of the locator unit and thus the user. 
         [0003]    U.S. Pat. No. 5,043,736 describes a portable location unit useful both as a cellular telephone and portable GPS that provides latitude and longitude information remotely to a base unit display. The system includes a small hand held receiver that receives signals from a satellite GPS and timing and computing circuits to provide location information signals. The hand held unit also includes a modem and transmitter to a cellular telephone network which is connected to the base unit computational system and display. The location of an individual or object can thus be determined at the remote station through the use of the cellular telephone network. 
         [0004]    U.S. Pat. No. 5,289,163 describes a child position monitoring device monitors the position of a child by detecting the signal strength of a radio frequency carrier from a transmitter attached to the child. If the signal of the radio frequency carrier is too weak, it means that the child is too far away from the adult who has the child position monitoring device. When this happens, the adult is informed that the child has wandered too far away through the use of an audio tone or through the use of vibrations coming from the device. Once the adult is notified that the child is too far away, the device also has a locating display for indicating the relative direction of the child with respect to the adult. The display uses eight LED&#39;s arranged around an emblem used to represent the position of the adult. The LED which lights up indicates the relative direction of the child. 
       SUMMARY 
       [0005]    The present invention relates to a wearable location tracking device that is worn on a users wrist, and a system that can track the device. In an embodiment, this tracking uses a combination of a GPS positioning satellite system beacon and modern G3 Cellular network position tracking capabilities. An embodiment describes G3 cellular internet connectivity to provide the two-way communication of the watch assembly. 
         [0006]    Embodiments incorporate methods to relay images and voice distress signals in the event of an alarm condition from the wearer of the device.

     DETAILED DESCRIPTION 
       [0012]    A wearable device that is worn on a person&#39;s wrist and the device having an appearance of a conventional wrist watch is used according to an embodiment.  FIGS. 1A-1C  shows the structure of the watch. The watch includes, as conventional, a bezel  100  and band  105 . The bezel covers a case  110  that includes the electronic components therein. The electronic components operate as described herein to relay the wearer&#39;s position to a remote monitoring device or station as described in detail herein. For example, in one embodiment the system may incorporates a cellular telephone transmitter and receiver using G3 Internet protocol, as well as GPS receiver and transmitter. The device can transmit data that represents the location of the watch, and hence its wearer at any time. This can be done in real-time as seen by the remote monitoring device. 
         [0013]    The watch face also includes settings buttons  120  that allows setting of different features such as the time. The watch face may also house the opening of a camera  125 . 
         [0014]      FIG. 1B  shows a view of the watch from its side view, showing the case  110  holding the electronics module, and a battery  130 . The clasp for the watch is formed by an electronic lock  150  that locks to a corresponding locking part  155 . The lock includes a latch portion  160  that locks to the electronic lock  150  to maintain the device on for example a child&#39;s arm.  FIG. 1C  shows the device as latched, where the latch device  160  extends upward into a cavity within the electronic lock portion  150 . 
         [0015]    The position of the device and wearer can be determined as shown in the communication flow diagram of  FIG. 2 . In a first technique, a person&#39;s location is determined via GPS data  210  from a GPS Satellite  205  sent to the locator watch on the person being monitored  200 . A second way of determining the location is by tracking the device with G3 mobile communications and triangulation from multiple cellular, PCS, or mobile phone service transmitting towers  225 ,  226 . Either or both of these can be used together, in order to provide a more thorough and complete coverage of the device and wearer&#39;s location. For example, this may provide improved location capability in areas such as within buildings where GPS satellite coverage is not sufficient to provide useful location information, whereas the G3 mobile communication triangulation will be used to determine the wearer&#39;s position. 
         [0016]    A host cellular telephone device or computer  250  that is connected to the Internet  255  can remotely control and/or communicate with the locating device over any Internet connection. 
         [0017]    The locating device contains an electronic lock mechanism  150 / 155 / 160  that is activated by the host  250 , e.g., via monitoring cellular telephone device or computer. The electronic lock is automatically activated when the clasp that retains the device to the wearers wrist is tampered with or attempted to be removed from the wearer, or if the device or if the wearer&#39;s position moves beyond a pre-determined area designated by the monitoring device. When the electronic lock is activated, a signal is sent to the monitoring device through the Internet and/or cellular service text messaging. 
         [0018]    The monitoring also causes a situation where camera  125  is activated to relay pictures to the monitoring device when the electronic lock is activated. This information can be helpful to determine the current emergency conditions, and to provide additional data as to the state of the wearer and why the electronic lock was activated. 
         [0019]    The locating wristwatch device has a conventional clasp on the watchband that can be adjusted to fit different sizes of wearers. 
         [0020]    The watchband clasp contains a switch that transmits an electronic signal to the electronic lock mechanism. The electronic lock, once activated, latches to prevent removal of the locating device from the wearer&#39;s wrist. If the clasp is forced open at that time, it causes an alarm to be established and sent over the internet connection to the monitoring host  250 . 
         [0021]    The watchband clasp can also be used as a ‘Panic Button’ by the wearer to send a distress signal to the monitoring host  250 , since it automatically causes an alarm. 
         [0022]      FIG. 3  illustrates a communication flow diagram of an embodiment. The tracker/owner is shown as  300 , and the watch itself is shown as  350 . The tracker can provide command information for the watch at  315 . This can be sent via cell phone at  310 , through the cellular service provider. It can alternatively be sent via computer at  320  through an Internet provider  305 . The Internet provider may also send the information through the cellular service provider, with the final destination being the watch itself at  350 . The cellular satellites are shown generically as  330 , and their position can be triangulated via the cell tracking central headquarters  325 . Any of this information can provide command information  335  which is sent to the watch  350 . 
         [0023]    A GPS satellite shown as  355  can also provide GPS position information  360  that can alternatively be used for determining the location of the watch. This can operate as described herein. 
         [0024]      FIG. 4  illustrates an embodiment, showing the different circuitry that can be used for the watch. The watch may have an antenna  400 , driven by an amplifier  405 . There can also be a GPS transceiver  410  which receives the GPS information. A cell processor  420  can allow the different communication over the cellular network. A camera  425  can also be activated as described herein, and can take pictures as necessary. The camera may be driven by a timer  430  to automatically cause the camera to take pictures at various intervals. A display driver IC  440  drives a display  445 . The processor  450  may carry out the various housekeeping operations. 
         [0025]    A lock processor  460  can be a generalized IC that monitors a switch  465  associated with the lock mechanism. The switch may be in one position as shown when locked, and may be in the other position when unlocked. The IC detects the lock/unlock, to create a warning when in when the device is tampered with. In addition, the lock can be electrically actuated at  470  by a relay based on a command sent over the cellular system, as previously described. 
         [0026]    Although only a few embodiments have been disclosed in detail above, other embodiments are possible and the inventors intend these to be encompassed within this specification. The specification describes specific examples to accomplish a more general goal that may be accomplished in another way. This disclosure is intended to be exemplary, and the claims are intended to cover any modification or alternative which might be predictable to a person having ordinary skill in the art. For example, other functions may be controllable from this watch. 
         [0027]    Those of skill would further appreciate that the various illustrative logical blocks, modules, circuits, and algorithm steps described in connection with the embodiments disclosed herein may be implemented as electronic hardware, computer software, or combinations of both. To clearly illustrate this interchangeability of hardware and software, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the exemplary embodiments of the invention. 
         [0028]    The various illustrative logical blocks, modules, and circuits described in connection with the embodiments disclosed herein, may be implemented or performed with a general purpose processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. The processor can be part of a computer system that also has a user interface port that communicates with a user interface, and which receives commands entered by a user, has at least one memory (e.g., hard drive or other comparable storage, and random access memory) that stores electronic information including a program that operates under control of the processor and with communication via the user interface port, and a video output that produces its output via any kind of video output format, e.g., VGA, DVI, HDMI, displayport, or any other form. 
         [0029]    A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration. These devices may also be used to select values for devices as described herein. 
         [0030]    The steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module may reside in Random Access Memory (RAM), flash memory, Read Only Memory (ROM), Electrically Programmable ROM (EPROM), Electrically Erasable Programmable ROM (EEPROM), registers, hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art.
