Description
- This application is a divisional of U.S. patent application Ser. No. 12/056,709 filed Mar. 27, 2008 (now allowed as U.S. Pat. No. 7,999,792) and claims benefit under 35 U.S.C. 121. The disclosure of U.S. patent application Ser. No. 12/056,709 is incorporated by reference herein in its entirety.
- 1. Field of the Invention
- The present invention is related to providing location determination features to subscribers of a location determination system. More particularly, the present invention is related to use, via the location determination system, of a location determining device configured for incorporation in consumer products such as vehicles, pet collars, footwear, mobile telephones, personal digital assistants (PDA), handheld computers, and for other uses as described herein.
- 2. Related Art
- Tracking technology and location determination is an expanding field. Current developments in tracking technology and methodologies are largely based upon handheld tracking devices that use Global Positioning System (GPS) technology. These approaches, however, are limited by inherent limitations of GPS based systems.
- For example, GPS systems require a clear sight-to-sky between a hand held device's receiver antenna and at least one orbiting GPS satellite. When this line-of-sight becomes obstructed, for example, by buildings, trees or largely anything that can obstruct sunlight, the reliability of GPS based location determination is significantly decreased.
- Another tracking system uses cell triangulation. Although cell triangulation essentially works everywhere a cell phone works and is more robust that GPS, cell phone triangulation is less accurate that GPS.
- Another significant limitation of current handheld location determination approaches is the lack of variety of location determination based services available to wireless subscribers. For example, beyond E911 and similar geo-location functions, users have limited ability to use one wireless device to efficiently determine location of another wireless device.
- What is needed therefore, are dual-mode location determination approaches that can overcome the aforementioned deficiencies and limitations. What is also needed are location determination devices that can be incorporated into various articles, including consumer products, for the purpose of tracking and/or location determination using cellular triangulation and/or a global positioning system (GPS). Finally, what is needed is a variety of personal location determination services that can be provided to wireless subscribers.
- Consistent with the principles of the present invention, as embodied and broadly described herein, the present invention includes a method for facilitating location determination. The method includes granting a subscriber access to a location determination network via a first device and determining location of a second device via the network. The determined location of the second device is provided to the first device.
- The present invention is directed to methods and systems for location determination and tracking (e.g., history of locations). Location can be determined, for example, through triangulation with cellular telephone towers and/or by use of GPS. Location and/or tracking information, such as tower locations, is uploaded to a remote device by wireless transmission (e.g., a cellular telephone link or infrared link) and/or by direct connection. Direct connection can include, for example, connection of a data cable between a location determining device and a device, and/or removal of a memory device from a location determination device and insertion of the memory device into another device, such as a computer-based system. Location and/or tracking information can be uploaded continuously, at predetermined times or intervals, and/or upon prompting.
- A dual-mode arrangement (e.g., GPS and cellular) for determining location is desirable, especially in cases where the reliability of GPS has been impacted due, for example, to line-of-sight obstructions noted above. A dual-mode arrangement can be optimized to capitalize on the efficiencies of GPS and cell triangulation.
- In a dual mode, for example, a handheld wireless device (e.g., a cell phone) can use either a cellular modem to locate its position when GPS is unavailable—or use GPS positioning when it is available.
- In the cell triangulation mode, location is traditionally derived through the use of multiple cell towers. More specifically, triangulations are based upon acquiring information from the cell towers in range, transmitting the raw data to servers where location calculations are made, and then sending the location information back to the handheld wireless device. Performing location triangulation external to the handheld device creates inefficiencies and potential bottlenecks in providing location information. In the present invention, however, triangulation can be performed locally, within the hand-held device.
- Triangulation with cellular telephone towers typically requires an account with a cellular telephone provider. Thus, where real-time location and/or tracking information is desired, such as with children and pets, and where the information is uploaded through a cellular telephone link, the location determination can be performed with cellular triangulation without incurring additional costs. Cellular location determination is provided for improved location determining availability, when GPS positioning is not available, and/or to periodically provide location information without incurring cellular access costs associated with cellular triangulation.
- The location determining methods and systems, of the present invention, can be incorporated into a variety of devices, such as consumer products, including for example, clothing, footwear, pet accessories such as pet collars, cellular telephones, PDAs, and other handheld computers. The methods and systems can also be incorporated into a variety of law enforcement products for attachment to vehicles, hand-carried accessories, and/or persons of interest.
- Additional features and advantages of the invention will be set forth in the description that follows, and in part will be apparent from the description, or may be learned by practice of the invention. The advantages of the invention will be realized and attained by the structure and particularly pointed out in the written description and claims hereof, as well as the appended drawings.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
- The accompanying drawings illustrate the present invention and, together with the description, farther serve to explain the principles of the invention and to enable one skilled in the pertinent art to make and use the invention.

FIG. 1 an illustration of an examplelocation determining device 100 in accordance with the present invention. Although numerous approaches exist to deriving and providing personal location information, thelocation determining device 100 is configured to facilitate person-to-person location determination. That is, thelocation determining device 100 can be configured to determine its own location, and then provide its determined location directly to aremote device 102. By way of example, theremote device 102 can be a cell phone, PDA, and/or other similar device. - As discussed in greater detail below, the
location determining device 100 is capable of multi-mode switching between, for example, use of GPS and cell tower triangulation to determine location information. This multi-mode switching capability permits thelocation determining device 100 to provide more robust location determination services than traditional devices. - The
location determining device 100, however, is only one component of a unique subscription system that provides subscribers a variety of person-to-person location determination services and features. - A. Dual Mode Switching Operation
-
FIG. 2A is a detailed block diagram illustration of the examplelocation determining device 100, illustrated inFIG. 1 . As shown inFIG. 2A , the personallocation determining device 100, includes acontroller 208, acellular telephone transceiver 202, and alocation determination module 206. Thelocation determination module 206 includes a cellular triangulation location determination module (not shown). The personallocation determining device 100 optionally includes aGPS transceiver 204, and a GPS location determination module within thelocation determination module 206. Conventional cellular telephone transceiver technology and/or conventional GPS technology can be used. Thecellular telephone 202 and theoptional GPS transceiver 204 enable a bi-model array switching capability of thedevice 100. Operation of the personallocation determining device 100, will be discussed more fully below. - The present invention, as illustrated in
FIG. 2A , provides a system where, for example, GPS location determination can be used when available. When GPS location determination is not available, thelocation determining device 100 can switch to triangulation location determination. Alternatively, when GPS location determination is unavailable, thelocation determining device 100 can switch from to triangulation to some other technique, such as Wireless Fidelity (WiFi) or fixed commercial transmitters when GPS is unavailable, if any of the other techniques provide a more accurate location determination. -
FIG. 3 is an illustration of the example location determining device ofFIG. 2A configured as a dual-mode system. InFIG. 3 , the personallocation determining device 100 determines location through the use of cellular triangulation and/or GPS. As known in the art, cellular triangulation relies on a cellular telephone transceiver that communicates withcellular towers 302 and determines its location by triangulation with thecellular towers 302. GPS relies on a GPS transceiver that receives signals fromGPS satellites 304, which allows the GPS transceiver to determine its geographic location. Theremote device 102 receives location information and/or tracking information from thelocation determining device 100. Theremote device 102 can include, for example, a computer-based system, a mobile telephone, a PDA, and/or other similar device. - Referring back to
FIG. 2A , during operation, thelocation determination module 206 receives information from thecellular telephone transceiver 202 and/or from theoptional GPS transceiver 204. Thelocation determination module 206 determines location information from the received information received from thetelephone transceiver 202 and/or from theGPS transceiver 204. Thelocation determination module 206 is configured or programmable to determine location information based on at least cellular triangulation information. Thelocation determination module 206 is optionally configured to determine location information based on cellular triangulation information when available, and from GPS information when cellular triangulation information is not available. - Alternatively, the
location determination module 206 can be configured to determine location information from a combination of cellular triangulation information and GPS information. To reduce costs associated with communicating with cellular towers 302 (see e.g.,FIG. 3 ), for example, thelocation determination module 206 can be configured to determine location information based on cellular triangulation information at some times, and from GPS information at other times. - Where the personal
location determining device 100 can be configured for both cellular triangulation location determination and GPS location determination, thecontroller 208 is configured to switch thelocation determination module 206 between a cellular triangulation location determination mode and a GPS location determination mode, as appropriate for the configuration. Thecontroller 208 is optionally user-programmable for different triangulation/GPS modes of operation. - The
controller 208 is configured to provide or upload the location information, optionally including tracking information, to the remote device 102 (FIG. 1 ) and/or to a memory device of the personallocation determining device 100. - The
controller 208 is configurable to upload the location information to theremote device 102 through a transmitter portion of thetransceiver 202 and thecellular towers 302. Alternatively, thecontroller 208 can be configured to upload the location information to a memory device and/or one or more external ports, which can include wire connector ports and/or infrared ports. Wire connector ports can include, for example, telephone ports, internet/Ethernet ports, printer ports, and/or universal serial bus (USB) ports. - The
controller 208 can also be configured to upload the location information to a universal resource locator (URL) address of the Internet, using a connector port and/or thecellular transceiver 202. - Where the personal
location determining device 100 includes a wire connector port, a wire connector can be coupled between the personallocation determining device 100 and theremote device 102, and/or between the personallocation determining device 100 and a transmitter that transmits the location information from the personallocation determining device 100 to theremote device 102. - Where the personal
location determining device 100 includes a wire connector port, a portable memory device, such as a USB memory stick, can be inserted into an appropriate wire connector port for receiving and storing the location information. The portable memory device can then be transferred to theremote device 102 for downloading of the location information. - The
controller 208 can be configured to upload location information continuously, at predetermined intervals, and/or upon receipt of a prompt from theremote device 102. Thecontroller 208 can receive prompts or requests for location information from theremote device 102 via the cell towers 302 and thetransceiver 202, and/or through an external port. Thecontroller 208 can optionally respond to such queries only after requestor verification, which can be based on caller identification information. - The
controller 208 can upload location information to a predetermined or programmed telephone number through thetransceiver 202, to one or more external ports, and/or to a predetermined or programmed URL. - The personal
location determining device 100 optionally includes location history memory configured to store location information so that it can be uploaded at a later time. This can be useful in situations where the personallocation determining device 100 is out of range for uploading the location information. - The
controller 208 can upload location information in one or more of a variety of formats, such as, without limitation, audio and/or computer readable data. The location information can include, for example, geographical coordinates (e.g., longitude and latitude), and/or a street address. - The
controller 208 can also send alerts and/or to upload location information upon a determination that a location determination is outside a programmable boundary, such as, for example, a perimeter of one's property (discussed more fully below). Such a feature is particularly useful in determining if a young child, pet, or individual under house arrest has left his home, or traveled beyond a property boundary. - The
remote device 102 optionally includes software in the form of a computer program product including computer readable media having computer program logic recorded thereon that causes a computer system to track the location of one or morepersonal location devices 100. More particularly, the computer program logic causes the computer system to receive location information uploaded by thecontroller 208, and to display the location information, such as on a map, and/or to store the location information in a memory device of the computer system. The software can also include alarm logic that causes the computer system to determine whether the received location determination falls outside of a programmable boundary and generate and alert (audio and/or visual), and/or that causes the computer system receive such a determination from the personallocation determining device 100 and generate an alert. - The personal
location determining device 100, or a portion thereof, is optionally enclosed within a housing configured for, or as, a consumer product and/or to be worn or carried by an individual. For example, the housing can be configured to fit within a pet collar or to attach to a pet collar (discussed in greater detail below). Alternatively, the housing can be configured to fit within in a shoe, including a tongue of the shoe or a cavity formed within the sole of the shoe. The housing can also be configured to attach externally to a shoe of for use with other consumer products including, such as mobile telephones, PDA, handheld computers and vehicles. The housing can also be incorporated into a variety law enforcement products for attachment to vehicles, hand-carried accessories, and/or persons of interest. - In one embodiment, the personal
location determining device 100, or a device in which it is incorporated, includes a power-down switch. In this configuration, thecontroller 208 is configured to maintain power to at least a portion of the personal location determining device 100 (e.g., thecontroller 208, thecellular telephone transceiver 202, theGPS transceiver 204, and/or the location determination module 206), on at least a limited basis, after the power-down switch is activated. This arrangement prevents an individual from intentionally or accidentally deactivating the personal location determination device such that it is no longer determining or uploading location information. - In some instances, however, it may be necessary for the
cellular telephone transceiver 202 and/or other portions of the personallocation determining device 100 to be more fully powered down, for example, at an airport. Thecontroller 208 is thus optionally configurable to more fully power-down thecellular telephone transceiver 202 and/or other portions of the personallocation determining device 100 when a location determination is within a predetermined boundary or location, such as an airport. Thecontroller 208 can also at least temporarily and partially power-up thecellular telephone transceiver 202 and/or other portions of the personallocation determining device 100 at a later time and without deactivation of the power-down switch. The later time can be determined according to an algorithm or a predetermined or programmable period of time. - In dual-mode, the present invention will use both GPS and cell tower triangulation. In this mode, the
personal location device 100 attempts to determine a location fix with GPS first. If the Assisted (or non-assisted) GPS location fix is available, thelocation device 100 will transmit the location coordinates back over the modem. If a GPS fix is not possible (for example because the unit is indoors), it will automatically switch to a cell-triangulation mode to determine location and will report that cell-triangulation is being used. Cell triangulation is completed on thepersonal location device 100 itself TheGPS transceiver 204 continues to stay on at timed intervals after a location is queried. If theGPS transceiver 204 detects a GPS signal, it will revert out of cell triangulation mode, back to the GPS mode. Under normal circumstances, the GPS mode provides higher location accuracy. Any time the unit switches between modes, it automatically sends a location report. - The dual-mode switching arrangement, discussed above, can be used in combination with a number of wireless systems, such as cellular, WiFi, and Worldwide Interoperability for Microwave Access (WiMax), etc., to report back to a system server. The dual-mode switching location technology can also include reporting back to a server in combination with a wireless system, and use of an Applied Service Provider model where the user pays on an interval or monthly bases to access this information.

FIG. 2B is anillustration 210 of an alternative configuration of the location determining 100 device, shown inFIG. 2A . InFIG. 2B , and in a manner similar to the illustration ofFIG. 2A , alocation determining device 100′ includes acellular telephone transceiver 202′, aGPS transceiver 204′, and acontroller 208′. InFIG. 2B , however, alocation determination module 206′ is located within a multi-mode position sever 212. InFIG. 2B , therefore, cellular triangulation as well as final position determination, occurs outside of the determiningdevice 100′. - By way of example, in
FIG. 2B , the cellular triangulation and final position determination information is provided to thelocation determining device 100′ via theInternet 214 and via acellular network 216. TheInternet 214 can also provide information to a personal computer (PC) 218 connected thereto, through either a wireless or wired connection. Thecellular network 216 can provide information to ahandheld device 220, such as a cellular phone. - B. Tri-Mode Switching Operation
- The present invention can also be configured to operate in conjunction with tri-mode switching location technology. In tri-mode operation, the
location determination device 100 is able to derive its location information through at least three possible sources: GPS, cellular triangulation, and WiFi, or any radio transmission (i.e., beacon technology). - C. Quad-Mode Switching Operation
- Further still, the present invention can be used in a quad-mode switching arrangement. By using quad-mode location technology, the
location determination device 100 can derive its location information through at least four possible sources: GPS, cellular triangulation, WiFi, and WiMax. - A. First Geofencing Example
-
FIG. 4 is anillustration 400 of thelocation determining device 100 operating in accordance with a first embodiment of the present invention. More particularly,FIG. 4 is an illustration of one example of the unique services available to a subscriber of a network system using the personallocation determining device 100. By way of example, such a network can be comprised of existing the infrastructure associated with cellular phones, GPS, and/or mapping services. - In the
illustration 400 ifFIG. 4 , thelocation determining device 100 can be used to provide real-time tracking of important possessions. InFIG. 4 , thedevice 100 relies on dual-mode GPS and cellular triangulation tracks where GPS alone is inadequate, such as many malls, buildings and garages. - In
FIG. 4 , for example, a subscriber to location determination services can use existing digital mapping services to specify ageographic region 402 of interest. In particular, a subscriber can define this region using any arbitrary polygon. Existing systems that accomplish this function require the user to specify a cener point and a radius. The present invention does away with this restriction, and allows the subscriber to define any arbitrary shape defined by straight line edges. The system subscriber (e.g., a parent) and owner of avehicle 404 can select a specific address orboundary 406 for which they have restricted a user of thevehicle 404 to cross. As shown inFIG. 4 , thevehicle 404 is equipped with the personallocation determining device 100. In the example ofFIG. 4 , thelocation determining device 100 can be used to notify the subscriber whenever thevehicle 404 crosses theboundary 406. Similarly, the subscriber can also be notified when thevehicle 404 arrives at a specific address. Operation of thelocation determining device 100, in the example ofFIG. 4 , will be discussed more fully below. - B. Second Geofencing Example
-
FIG. 5 is anotherexample illustration 500 of thelocation determining device 100 configured to operate in accordance with the present invention. In theillustration 500, a pet owner may have concern with the location of apet 502. For example, although thepet 502 does not typically venture beyond ageographic boundary 504 of the owner'sproperty 506, the owner may desire to be notified if and when thepet 502 crosses theboundary 504. In theillustration 500, thepet 502 wears apet finder device 508, equipped with a specifically configuredlocation determining device 510. Here, the owner can receive notification forwarded to a remote device, such as a cell phone, whenever thepet 502 crosses theboundary 504. This process is explained more fully with reference toFIG. 6 . - C. Example Geofencing Operational Scenario
-
FIG. 6 a more detailed illustration 600 showing exemplary operation and use of thelocation determining device 100 in accordance with the illustrations ofFIGS. 5 and 6. As shown inFIG. 6 , as thepet 502 crosses theproperty boundary 504, thelocation device 100 determines a current location of thedevice 100. As discussed above, this determination can be derived, by way of example, through triangulation using the cell towers 302. On the other hand, thelocation determination device 100 can derive its location based upon theGPS satellites 304. Alternatively, thelocation determination device 100 can derive its location based upon a combination of the cell towers 302 and theGPS satellites 304. This determination can be based upon periodic location determination performed in accordance with a subscriber selectable timing scheme. - In
FIG. 6 , the subscriber's location determination criteria can be specified and input to a network system controlled by a cellular or location determination service provider. For example, the service provider can enter the subscriber's location determination criteria as data to aserver 602, associated with the network system. The actual geographic location of thepet 502 can be forwarded to theserver 602 alongdata path 604. Date representative of the actual location of thepet 502 will be compared with the subscriber's location determination criteria. When the comparison indicates that thepet 502 has crossed theboundary 504, a notification will be forwarded to the subscriber using a variety of mechanisms. - For example, the subscriber can choose to be notified via wireless device, wired device, or by email. If the subscriber chooses wireless notification, the
server 602 forwards notification, by way of thecellular towers 302 and a wireless data path 606, to the subscriber via thecell phone 102, aPDA device 608, or a watch device 610. The watch device 610 can be equipped with a unique graphical user interface to provide suitable audio and/or video notification to the subscriber in accordance with the illustration 600. - Alternatively, or in combination therewith, the subscriber can choose to receive e-mail notification. If the subscriber has chosen email notification, when the
pet 502 crosses thegeographic boundary 504, an email will be forwarded from theserver 602, via theInternet 612, to a subscriber'scomputer terminal 614. In this alternative arrangement, the arrangement 600 ofFIG. 6 provides a user-friendly web-based approach for map and satellite tracking of a subscriber's possessions. This feature is also perfectly suitable for motorcycles, bikes, luggage, kid's backpacks, golf clubs, and more. - D. Example End-to-End System Operation
- In the present invention, referring back to
FIGS. 2B and 3 for example, thelocation determining device 100′ can query theGPS transceiver 204′ for a position (e.g., on a scheduled basis, or in response to a remote request from the cellular network). If themobile device 100′ is able to obtain a GPS position from the GPS transceiver, it forwards that position to themulti-mode position server 212. If themobile device 100′ is unable to obtain a GPS position from theGPS transceiver 204′, it relays this fact to theposition server 212. Alternatively, WiFi or information from fixed radio transmitters such as commercial broadcast radio and television stations can be used to relay or provide information related to GPS position determination. - Also relayed to the
position server 212 is any other information that themobile device 100′ can obtain, or deduce from thecellular network 216, which can be used to provide a cellular based position of themobile device 100′. This information includes, but is not limited to, the identification of the cell towers 302 that are visible, and tower signal strength. Themulti-mode position server 212 then determines a position estimate for thelocation determining device 100′. As noted above, alternatively, the position determination can be performed on thelocation determining device 100′ itself. - By way of example, the estimate for the
location determining device 100′ can be determined in the following manner: - A. If GPS position is provided from the mobile device, then this position is used as the position estimate.
- B. If GPS position is reported as unavailable from the mobile device, the position server then computes a position estimate on the basis of measured parameters of the cellular network as seen from the mobile device.
- C. This position server estimate is then forwarded to a user, upon request, or on a schedule, either to a device attached to the internet, or another mobile display. This can either be through the use of a web page, or a directed message.
