Abstract

An accessory-type GPS (Global Positioning System) receiver comprises a mobile terminal side plug connector, and a cradle/hand-free side receptacle connector disposed substantially opposite thereto. The GPS receiver further comprises a power supply that receives power from a mobile terminal power charge line being operatively coupled between the mobile terminal side plug connector and the cradle/hand-free side receptacle connector. The plug connector is used to pass GPS data directly to a mobile terminal. The receptacle connector is used to pass non-GPS data to the mobile terminal via the plug connector.

Claims

1. A GPS (Global Positioning System) receiver, comprising:

at least one mobile terminal side plug connector;

at least one cradle/hand-free side receptacle connector; and

at least one power supply receiving power from at least one mobile terminal power charge line being operatively coupled between said at least one mobile terminal side plug connector and said at least one cradle/hand-free side receptacle connector.

2. The GPS receiver of claim 1, wherein said at least one mobile terminal side plug connector is disposed substantially opposite said at least one cradle/hand-free side receptacle connector.

3. The GPS receiver of claim 1, further comprising at least one GPS signal processor adapted for UART (Universal Asynchronous Receiver/Transmitter) communication with at least one mobile terminal via said at least one mobile terminal side plug connector.

4. The GPS receiver of claim 3, wherein said at least one GPS signal processor receives power from said at least one power supply.

5. The GPS receiver of claim 3, wherein said at least one GPS signal processor receives power from at least one coin power cell to maintain backed-up GPS data while said at least one GPS signal processor is in a state of “

sleep”

.

6. The GPS receiver of claim 3, further comprising at least one switch-type antenna portion being operatively coupled to said at least one GPS signal processor via at least one GPS RF (Radio Frequency) filter, said at least one switch-type antenna portion being used for wireless communication with at least one GPS satellite.

7. The GPS receiver of claim 6, wherein said at least one switch-type antenna portion comprises at least one internal passive GPS antenna, and at least one external active GPS antenna.

8. The GPS receiver of claim 7, wherein when said at least one internal passive GPS antenna is in an “

on”

state, said at least one external active GPS antenna is in an “

off”

state.

9. The GPS receiver of claim 7, wherein when said at least one external active GPS antenna is in an “

on”

state, said at least one internal passive GPS antenna is in an “

off”

state.

19. The GPS receiver of claim 1, wherein each of said at least one mobile terminal side plug connector and said at least one cradle/hand-free side receptacle connector is a standard 24-pin connector, respectively.

10. A GPS (Global Positioning System) receiver, comprising:

at least one plug-type connector used to pass GPS data directly to at least one mobile terminal;

at least one receptacle-type connector used to pass non-GPS data to said at least one mobile terminal via said at least one plug-type connector; and

at least one power supply receiving power from at least one mobile terminal power charge line being operatively coupled between said at least one plug-type connector and said at least one receptacle-type connector.

11. The GPS receiver of claim 10, wherein said at least one plug-type connector is disposed substantially opposite said at least one receptacle-type connector.

12. The GPS receiver of claim 10, further comprising at least one GPS signal processor adapted for UART (Universal Asynchronous Receiver/Transmitter) communication with said at least one mobile terminal via said at least one plug-type connector.

13. The GPS receiver of claim 12, wherein said at least one GPS signal processor receives power from said at least one power supply.

14. The GPS receiver of claim 12, wherein said at least one GPS signal processor receives power from at least one coin power cell to maintain backed-up GPS data while said at least one GPS signal processor is in a state of “

sleep”

.

15. The GPS receiver of claim 12, further comprising at least one switch-type antenna portion being operatively coupled to said at least one GPS signal processor via at least one GPS RF (Radio Frequency) filter, said at least one switch-type antenna portion being used for wireless communication with at least one GPS satellite.

16. The GPS receiver of claim 15, wherein said at least one switch-type antenna portion comprises at least one internal passive GPS antenna, and at least one external active GPS antenna.

17. The GPS receiver of claim 16, wherein when said at least one internal passive GPS antenna is in an “

on”

state, said at least one external active GPS antenna is in an “

off”

state.

18. The GPS receiver of claim 16, wherein when said at least one external active GPS antenna is in an “

on”

state, said at least one internal passive GPS antenna is in an “

off”

state.

20. The GPS receiver of claim 10, wherein each of said at least one plug-type connector and said at least one receptacle-type connector is a standard 24-pin connector, respectively.
