Abstract

A navigation system having a transceiver configured to receive a first GPS location signal corresponding to a geographic location of the navigation system and a second GPS location signal corresponding to a geographic location of a vehicle, a processor operatively coupled to the transceiver, the processor configured to determine a relative distance of the navigation system from the vehicle based on the first GPS location signal and the second GPS location signal, and a user interface operatively coupled to the processor, the user interface provides an alert at a predetermined distance from the vehicle.

Claims

1. A navigation system, comprising:

a transceiver configured to receive a first GPS location signal corresponding to a geographic location of the navigation system and a second GPS location signal corresponding to a geographic location of a vehicle;

a processor operatively coupled to the transceiver, the processor configured to determine a relative distance of the navigation system from the vehicle based on the first GPS location signal and the second GPS location signal; and

a user interface operatively coupled to the processor, the user interface provides an alert at a predetermined distance from the vehicle.

2. The navigation system of claim 1, wherein the processor is further configured to determine directional information from the geographic location of the navigation system to the geographic location of the vehicle.

3. The navigation system of claim 1, wherein the transceiver is further configured to receive an identification code that identifies the vehicle.

4. The navigation system of claim 1, wherein the transceiver is further configured to transmit the first GPS location signal to a vehicle transceiver, the vehicle transceiver being coupled to the vehicle.

5. The navigation system of claim 1, wherein the vehicle is an emergency vehicle.

6. The navigation system of claim 1, further comprising a siren activation system for actuating the transceiver to transmit the first GPS location signal.

7. The navigation system of claim 1, wherein the transceiver is further configured to transmit a navigation system identification code to a vehicle transceiver, the navigation system identification code identifies the navigation system, the vehicle transceiver being coupled to the vehicle.

8. The navigation system of claim 1, wherein the user interface is selected from a group consisting of a display unit, an output device and a speaker system.

9. A machine readable medium that provides instructions, which when read by a processor, cause the machine to perform operations comprising:

receiving a first GPS location signal corresponding to a geographic location of a navigation system;

receiving a second GPS location signal corresponding to a geographic location of a vehicle;

computing a relative distance of the navigation system from the vehicle based on the first GPS location signal and the second GPS location signal; and

transmitting the relative distance to a user interface to provide an alert at a predetermined distance from the vehicle.

10. The machine readable medium of claim 9, further comprising determining directional information from the geographic location of the navigation system to the geographic location of the vehicle.

11. The machine readable medium of claim 9, further comprising receiving a vehicle identification code that identifies the vehicle.

12. The machine readable medium of claim 9, further comprising transmitting the first GPS location signal to a vehicle transceiver, the vehicle transceiver being coupled to the vehicle.

13. The machine readable medium of claim 9, wherein the vehicle is an emergency vehicle.

14. The machine readable medium of claim 9, further comprising actuating a siren activation system to trigger the navigation system to transmit the first GPS location signal.

15. The machine readable medium of claim 9, further comprising transmitting a navigation system identification code to a vehicle transceiver, the navigation system identification code identifies the navigation system, the vehicle transceiver being coupled to the vehicle.

16. The machine readable medium of claim 9, wherein the user interface is selected from a group consisting of a display unit, an output device and a speaker system.

17. A method for determining the presence of a vehicle at a predetermined distance from a navigation system, the method comprising:

receiving a first GPS location signal corresponding to a geographic location of the navigation system;

receiving a second GPS location signal corresponding to a geographic location of the vehicle;

mapping the first GPS location signal and the second GPS location signal to a geographical coordinate data; and

alerting a user of the navigation system at a predetermined distance from the vehicle.

18. The method of claim 17, further comprising computing a relative distance of the navigation system from the vehicle based on the first GPS location signal and the second GPS location signal.

19. The method of claim 17, further comprising displaying an image of the vehicle on a display unit of the navigation system.

20. The method of claim 17, further comprising actuating a siren activation system to trigger the navigation system to transmit the first GPS location signal.
