first embodiment
[0079]FIG. 4 is an illustration 400 of the location determining device 100 operating in accordance with 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 personal location 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.
[0080]In the illustration 400 if FIG. 4, the location determining device 100 can be used to provide real-time tracking of important possessions. In FIG. 4, the device 100 relies on dual-mode GPS and cellular triangulation tracks where GPS alone is inadequate, such as many malls, buildings and garages.
[0081]In FIG. 4, for example, a subscriber to location determination services can use existing digital mapping services to specify a geographic region 402 of interest. In particular, a subscriber can define this region using any arbitrary poly...
second embodiment
[0101]FIG. 10 is a flowchart of an exemplary method 1000 of practicing the present invention. In the method 1000, a subscriber is granted access to a location determination network via a first device, as indicated in step 1002. The first device is configurable for dual mode location determination. In step 1004, the subscriber is permitted to remotely determine location of a second device using the network, the location of the second device being provided to the user via the first device.
