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 telephone company and displayed on the user'"'"'s television. In the present embodiment, the user'"'"'s television is connected with the telephone company by a telephone line and a modem. Once the request is received at the telephone 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 telephone company. The acquired position information is then transmitted from the telephone 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 representing the location of an item, said system comprising:

a position determining system coupled to an item to be located, said position determining system adapted to transmit position information of said item therefrom;

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

a television adapted to display a visual representation of said position information of said item;

a telephone company communicatively coupled to said receiver said telephone company adapted to transmit said position information received at said receiver to said television;

an automatic tracking system communicatively coupled to said telephone company, said automatic tracking system adapted to track said item and provide tracking information on said item to said telephone company, and

a telephone communicatively coupled to said telephone company, said telephone adapted to request transmission of said position information of said item from said telephone company to said television.

2. The system of 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.

3. The system of claim 1 wherein said position determining system is selected from the class of ground-based radio navigation systems consisting of LORAN and FM subcarrier.

4. The system of claim 1 wherein said item to be located is a vehicle.

5. The system of claim 1 wherein said telephone is communicatively coupled to said telephone company by an ISDN link.

6. The system of claim 1 wherein said telephone is communicatively coupled to said telephone company by a dial up telephone line link.

7. The system of claim 1 wherein said telephone is communicatively coupled to said telephone company by a dedicated telephone line link.

8. The system of claim 1 wherein said telephone is communicatively coupled to said telephone company by a fiber optic link.

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

requesting, from a telephone company, a visual representation of the location of an item,

acquiring, at said telephone company, position information indicative of the location of said item,

converting said position information indicative of the location of said item to be located to a format compatible for transmission to and subsequent display on a television;

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

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

10. The method as recited in claim 9 wherein said step of requesting, from a telephone company, a visual representation of the location of an item further comprises requesting, from a telephone company, a visual representation of the location of a vehicle.

11. The method as recited in claim 9 wherein said step of acquiring, at said telephone company, 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.

12. The method as recited in claim 9 wherein said step of acquiring, at said telephone company, 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 and FM subcarrier to generate said position information indicative of said location of said item.

13. The method as recited in claim 9 wherein said display device is communicatively coupled to said telephone company by an ISDN link.

14. The method as recited in claim 9 wherein said display device is communicatively coupled to said telephone company by a fiber optic link.

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

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

generating position information indicative of the location of said item,

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

transmitting said position information from said receiver which is communicatively coupled to said item to said telephone company, said telephone company also communicatively coupled to said receiver,

converting said position information indicative of the location of said item to a format compatible for transmission to and subsequent display on said television,

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

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

16. The method as recited in claim 15 wherein said step of telephonically requesting that a visual representation of the location of an item be transmitted from a telephone 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 telephone company and displayed on said television.

17. The method as recited in claim 15 wherein said step of generating position information indicative of the location f 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.

18. The method as recited in claim 15 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 and FM subcarrier.
