Abstract

An apparatus for providing power and information to an electronic device housed in a first housing. The apparatus may generally comprise a coupling element, a receiver operable to wirelessly receive information, and a cable. The coupling element is housed within a second housing that is operable to be at least partially inserted into an automobile cigarette lighter socket to acquire power therefrom. The cable extends from the second housing and is operable to couple with the electronic device or a mount associated with the electronic device to provide power from the coupling element and information from the receiver to the electronic device. The cable may generally include a first portion for housing an antenna that is operable to electrically couple with the receiver and a second portion for housing one or more wires. The one or more wires are operable to provide the power and the information to the electronic device or the mount associated with the electronic device.

Claims

1. An apparatus for providing power and information to an electronic device housed in a first housing, the apparatus comprising:

a coupling element housed within a second housing, the second housing operable to be at least partially inserted into an automobile cigarette lighter socket to acquire power therefrom;

a receiver operable to wirelessly receive information; and

a cable extending from the second housing and operable to couple with the electronic device or a mount associated with the electronic device to provide power from the coupling element and information from the receiver to the electronic device, the cable including—

a first portion for housing an antenna, the antenna operable to electrically couple with the receiver,

a second portion for housing one or more wires, the one or more wires operable to provide the power and the information to the electronic device or the mount associated with the electronic device, and

an air gap disposed between the antenna and the one or more wires.

2. The apparatus of claim 1, wherein the receiver is housed within the second housing.

3. The apparatus of claim 1, wherein the receiver is housed separate from the second housing and coupled with the cable.

4. The apparatus of claim 1, wherein the receiver is a traffic receiver operable to receive TMC formatted traffic information.

5. The apparatus of claim 1, wherein the receiver is a traffic receiver operable to receive MSN DIRECT formatted traffic information.

6. The apparatus of claim 1, wherein the air gap is disposed within the first portion of the cable.

7. The apparatus of claim 1, wherein the air gap is disposed within the second portion of the cable.

8. The apparatus of claim 1, wherein the cable further includes an antenna connection plug operable to be removably coupled with an external antenna to allow signals from the external antenna to pass down the integral antenna to form a transmission line to the receiver.

9. The apparatus of claim 1, further including a filtering element operable to filter power passing through the cable, the filtering element being disposed on the cable towards an end opposite the coupling element.

10. An apparatus for providing power and information to an electronic device housed in a first housing, the apparatus comprising:

a coupling element housed within a second housing, the second housing operable to be at least partially inserted into an automobile cigarette lighter socket to acquire power therefrom;

a traffic receiver housed within the second housing and operable to wirelessly receive traffic information; and

a cable extending from the second housing and operable to couple with the electronic device or a mount associated with the electronic device to provide power from the coupling element and traffic information from the receiver to the electronic device, the cable including—

a first portion for housing an antenna, the antenna operable to electrically couple with the receiver,

a second portion for housing one or more wires, the one or more wires operable to provide the power and the traffic information to the electronic device or the mount associated with the electronic device, and

an air gap disposed between the antenna and the one or more wires.

11. The apparatus of claim 10, wherein the receiver is operable to receive TMC formatted traffic information.

12. The apparatus of claim 10, wherein the receiver is operable to receive MSN DIRECT formatted traffic information.

13. The apparatus of claim 10, wherein the air gap is disposed within the first portion of the cable.

14. The apparatus of claim 10, wherein the air gap is disposed within the second portion of the cable.

15. The apparatus of claim 10, wherein the cable further includes an antenna connection plug operable to be removably coupled with an external antenna to allow signals from the external antenna to pass down the integral antenna to form a transmission line to the receiver.

16. The apparatus of claim 10, further including a filtering element operable to filter power passing through the cable, the filtering element being disposed on the cable towards an end opposite the coupling element.

17. An apparatus for providing power and information to an electronic device housed in a first housing, the apparatus comprising:

a coupling element housed within a second housing, the second housing operable to be at least partially inserted into an automobile cigarette lighter socket to acquire power therefrom;

a traffic receiver housed within the second housing and operable to wirelessly receive traffic information;

a cable extending from the second housing and operable to couple with the electronic device or a mount associated with the electronic device to provide power from the coupling element and traffic information from the receiver to the electronic device, the cable including—

a first portion for housing an antenna, the antenna operable to electrically couple with the receiver,

a second portion for housing one or more wires, the one or more wires operable to provide the power and the traffic information to the electronic device or the mount associated with the electronic device,

an air gap disposed between the antenna and the one or more wires, and

an antenna connection plug operable to be removably coupled with an external antenna to allow signals from the external antenna to pass down the integral antenna to form a transmission line to the receiver; and

a filtering element operable to filter power passing through the cable, the filtering element being disposed on the cable towards an end opposite the coupling element.

18. The apparatus of claim 17, wherein the air gap is disposed within the first portion of the cable.

19. The apparatus of claim 17, wherein the air gap is disposed within the second portion of the cable.

20. The apparatus of claim 17, wherein the cable includes a third portion positioned between the first portion and the second portion, the third portion including the air gap.

21. A cable operable to electrically couple a cigarette lighter adapter and an electronic device or a mount associated with the electronic device, the cable comprising:

a first portion for housing an antenna operable to be utilized by a receiver associated with the cigarette lighter adapter;

a second portion for housing one or more wires, the one or more wires operable to provide power and information from the cigarette lighter adapter to the electronic device or the mount associated with the electronic device; and

an air gap disposed between the antenna and the one or more wires.

22. The cable of claim 21, further including an antenna connection plug operable to be removably coupled with an external antenna to allow signals from the external antenna to pass down the integral antenna to form a transmission line.

23. The cable of claim 21, further including a filtering element operable to filter power passing through the cable, the filtering element being disposed on the cable towards an end opposite the cigarette lighter adapter.
