Abstract

A system for visually representing the location of an item on a television. In one embodiment, a user of the present system telephonically requests that a visual representation of the location of an item be transmitted from a cable television company and displayed on the user'"'"'s television. In the present embodiment, the user'"'"'s television is connected with the cable television company by cable. Once the request is received at the cable television company, position information indicative of the location of the item is transmitted from the item to a receiver. The position information is then transmitted from the receiver to the cable television company. The acquired position information is then transmitted from the cable television company to the user'"'"'s television. A visual representation of the position of the item is then displayed on the user'"'"'s television.

Claims

1. A system for visually providing position information representing the location of an item, said system comprising:

a cable television service provider coupled to a receiver which, in turn, is communicatively coupled to a position determining system monitoring an item to be located, said receiver adapted to receive position information of said item, said cable television service provider further adapted to transmit said position information received at said receiver to a display device.

2. The system for visually providing position information as recited in claim 1 wherein said cable television service provider is coupled to a data input device, said data input device adapted to request transmission of said position information of said item from said cable television service provider to said display device.

3. The system for visually providing position information as recited in claim 1 wherein said position determining system is selected from the class of satellite-based radio navigation systems consisting of the Global Positioning System and the Global Orbiting Navigation System.

4. The system for visually providing position information as recited in claim 1 wherein said position determining system is selected from the class of ground-based radio navigation systems consisting of LORAN, Shoran, Decca, and TACAN.

5. The system for visually providing position information as recited in claim 1 wherein said cable television service provider is coupled to a data input device, said data input device adapted to request transmission of said position information of said item from said cable television service provider to a television.

6. The system for visually providing position information as recited in claim 1 wherein said cable television service provider is coupled to a telephone, said telephone for requesting transmission of said position information of said item from said cable television service provider to said display device.

7. A system for visually representing the location of an item, said system comprising:

a position determining system coupled to an item to be located,

a receiver communicatively coupled to said position determining system, said receiver adapted to receive position information of said item,

a display device adapted to display a visual representation of said position information of said item,

a cable television service provider communicatively coupled to said receiver, said cable television service provider transmitting said position information received at said receiver to said display device, and

a data input device communicatively coupled to said cable television service provider, said data input device adapted to request transmission of said position information of said item from said cable television service provider to said display device.

8. The system of claim 7 wherein said position determining system is selected from the class of satellite-based radio navigation systems consisting of the Global Positioning System and the Global Orbiting Navigation System.

9. The system of claim 7 wherein said position determining system is selected from the class of ground-based radio navigation systems consisting of LORAN, Shoran, Decca, and TACAN.

10. The system of claim 7 wherein said item to located is a vehicle.

11. The system of claim 7 wherein said display device is a television.

12. The system of claim 7 wherein said data input device is a telephone.

13. A method for visually representing the location of an item on a display device comprising the steps of:

requesting, from a cable television service provider, a visual representation of the location of an item,

acquiring, at said cable television service provider, position information indicative of the location of said item,

transmitting said acquired position information from said cable television service provider to a display device,

displaying a visual representation of said position information of said item on said display device.

14. The method as recited in claim 13 wherein said step of requesting, from said cable television service provider, a visual representation of the location of an item further comprises requesting, from said cable television service provider, a visual representation of the location of a vehicle.

15. The method as recited in claim 14 wherein said step of using a data input device to perform said request further includes using a telephone to perform said request.

16. The method as recited in claim 13 wherein said step of requesting, from said cable television service provider, a visual representation of the location of an item further includes using a data input device to perform said request.

17. The method as recited in claim 13 wherein said step of acquiring, at said cable television service provider, position information indicative of the location of said item, further includes the step of using a position determining system selected from the class of satellite-based radio navigation systems consisting of the Global Positioning System and the Global Orbiting Navigation System to generate said position information indicative of said location of said item.

18. The method as recited in claim 13 wherein said step of acquiring, at said cable television service provider, position information indicative of the location of said item, further includes the step of using a position determining system selected from the class of ground-based radio navigation systems consisting of LORAN, Shoran, Decca, and TACAN to generate said position information indicative of said location of said item.

19. The method as recited in claim 13 wherein said step of transmitting said acquired position information from said cable television service provider to said display device further comprises transmitting said acquired position information from said cable television service provider to a television.

20. A method for visually representing the location of an item on a television comprising the steps of:

requesting that a visual representation of the location of an item be transmitted from a cable television company and displayed on a television,

generating position information indicative of the location of said item,

receiving said position information at a receiver communicatively coupled to said item,

transmitting said position information from said receiver to said cable television company communicatively coupled to said receiver,

transmitting said acquired position information from said cable television company to said television,

displaying a visual representation of said position information of said item on said television.

21. The method as recited in claim 20 wherein said step of requesting that a visual representation of the location of an item be transmitted from a cable television company and displayed on a television further comprises the step of telephonically requesting that a visual representation of the location of a vehicle be transmitted from said cable television company and displayed on said television.

22. The method as recited in claim 20 wherein said step of generating position information indicative of the location of said item further comprises the step of generating said position information using a position determining system selected from the class of satellite-based radio navigation systems consisting of the Global Positioning System and the Global Orbiting Navigation System.

23. The method as recited in claim 20 wherein said step of generating position information indicative of the location of said item further comprises the step of generating said position information using a position determining system selected from the class of ground-based radio navigation systems consisting of LORAN, Decca, and TACAN.
