Abstract

A device is provided, which uses a positioning system, to determine a first geographic location, while the device is located at the first geographic location. Information concerning the first geographic location may be stored in a computer memory. The device may be moved from the first geographic location to a second geographic location which is substantially different from the first geographic location. The device may be used to determine the second geographic location, while the device is located at the second geographic location. Information concerning the second geographic location may be stored in a computer memory. Directions from the second geographic location to the first geographic location may be provided by the device to a user. The directions may be displayed on a computer monitor or provided orally by use of a voice system.

Claims

1. A method, comprising:

using a device, which uses a positioning system, to determine a first geographic location, while the device is located at the first geographic location;

storing, in a computer memory, information concerning the first geographic location;

moving the device from the first geographic location to a second geographic location which is substantially different from the first geographic location;

using the device to determine the second geographic location, while the device is located at the second geographic location;

storing in a computer memory, information concerning the second geographic location;

and providing directions from the second geographic location to the first geographic location.

2. The method of claim 1 wherein

the device uses a global positioning system.

3. The method of claim 1 wherein

an automobile is located at the first geographic location.

4. The method of claim 1 wherein

the device includes a GPS capable mobile telephone.

5. The method of claim 1 wherein

the device is a handheld device.

6. The method of claim 1 wherein

the device includes a remote keyless vehicle entry circuit for locking and unlocking a vehicle;

and the first geographic location is a geographic location of the vehicle.

7. The method of claim 6 wherein

the device determines the first geographic location automatically and stores the information concerning the first geographic location automatically when a user locks the vehicle using the remote keyless entry circuit.

8. The method of claim 1 wherein

the device includes a voice system and a voice recognition system.

9. The method of claim 8 wherein

the voice recognition system recognizes oral instructions from a user human being concerning which selected one of a plurality of stored geographic locations the user human being wants to return to;

and

wherein the voice system speaks out a direction and a distance to the selected one of the plurality of stored geographic locations.

10. The method of claim 1 wherein

the directions are provided by displaying them on a computer monitor.

11. The method of claim 10 wherein

the directions are provided by displaying on the computer monitor a line with an arrow pointing from the second geographic location to the first geographic location, and by displaying on the computer monitor a distance between the first geographic location and the second geographic location.

21. The apparatus of claim 11 further comprising

a computer monitor;

and wherein the directions are provided by displaying them on the computer monitor.

22. The apparatus of claim 21 wherein

the directions are provided by displaying on the computer monitor a line with an arrow pointing from the second geographic location to the first geographic location, and by displaying on the computer monitor a distance between the first geographic location and the second geographic location.

12. An apparatus comprising

a device including

a computer processor;

a computer memory;

and a receiver;

wherein the processor is programmed to use a positioning system, to determine a first geographic location, while the device is located at the first geographic location;

wherein the processor is programmed to cause information concerning the first geographic location to be stored in the computer memory;

wherein the processor is programmed to use the positioning system, to determine a second geographic location, while the device is located at the second geographic location, the second geographic location substantially different from the first geographic location;

.

wherein the processor is programmed to cause information concerning the second geographic location to be stored in the computer memory; and

wherein the processor is programmed to provide directions from the second geographic location to the first geographic location.

13. The apparatus of claim 12 wherein

the positioning system used by the processor is a global positioning system.

14. The apparatus of claim 12 wherein

an automobile is located at the first geographic location.

15. The apparatus of claim 12 wherein

the device includes a GPS capable mobile telephone.

16. The apparatus of claim 12 wherein

the device is a handheld device.

17. The apparatus of claim 12 wherein

the device includes a remote keyless vehicle entry circuit for locking and unlocking a vehicle.

18. The apparatus of claim 17 wherein

the processor is programmed to determine the first geographic location automatically and store the information concerning the first geographic location automatically when a user locks the vehicle using the remote keyless entry circuit.

19. The apparatus of claim 12 wherein

the device includes a voice system and a voice recognition system.

20. The apparatus of claim 19 wherein

the voice recognition system recognizes oral instructions from a user human being concerning which selected one of a plurality of stored geographic locations the user human being wants to return to;

and

wherein the voice system speaks out a direction and a distance to the selected one of the plurality of stored geographic locations.
