Abstract

Techniques are disclosed for systems and methods to provide polarization alignment for wireless networking systems. A polarization aligned wireless networking system may include one or more sensors, controllers, user interfaces, and/or other modules mounted to or in proximity to a vehicle. Antennas for each of the electronic devices may be implemented with linear polarization components that can be substantially aligned with a lateral axis of the vehicle. Each electronic device may be implemented with a logic device adapted to use a corresponding antenna to form one or more wireless links between the various electronic devices.

First claim

What is claimed is:

1. A system comprising:
a first electronic device mounted to a vehicle, wherein the first electronic device is coupled to a first antenna; and
a second electronic device mounted to the vehicle, wherein the second electronic device is coupled to a second antenna, wherein the second electronic device is adapted to communicate with the first electronic device over a wireless link via, at least in part, the first and second antennas, and wherein linear polarization components of the first and second antennas are substantially aligned with a lateral axis of the vehicle.

2. The system of claim 1 , wherein:
the first electronic device comprises a wind sensor, a water speed sensor, an orientation sensor, a GPS, a gyroscope, an accelerometer, a temperature sensor, a barometer, or a steering sensor; and
the second electronic device comprises a user interface.

3. The system of claim 1 , wherein:
the first electronic device is mounted substantially above or below a user level of the vehicle; and
the second electronic device is located substantially at the user level of the vehicle.

4. The system of claim 1 , wherein:
the first antenna is fixed relative to the vehicle substantially near a masthead of the vehicle; and
the second antenna is fixed relative to the vehicle and substantially near a user level of the vehicle.

5. The system of claim 1 , further comprising:
a third electronic device in proximity to the vehicle, wherein the third electronic device is adapted to communicate with the first or second device over at least another wireless link via, at least in part, a third antenna electrically coupled to the third electronic device, and wherein a linear polarization component of the third antenna is substantially aligned with a lateral axis of the vehicle.

6. The system of claim 5 , wherein:
the third electronic device is physically coupled to a user of the vehicle.

7. The system of claim 5 , wherein:
the first and third devices are adapted to communicate over the at least another wireless link; and
the second and third devices are adapted to communicate over the wireless link and the at least another wireless link.

8. The system of claim 5 , wherein:
the at least another wireless link comprises two wireless links;
the first and third devices are adapted to communicate over at least a first one of the two wireless links; and
the second and third devices are adapted to communicate over at least a second one of the two wireless links.

9. The system of claim 5 , wherein:
the first antenna is fixed relative to the vehicle substantially near a masthead of the vehicle;
the second antenna is fixed relative to the vehicle substantially near a mastfoot of the vehicle;
the third antenna is fixed relative to the vehicle substantially near a cockpit of the vehicle.

10. A method comprising:
forming, using first and second antennas, a wireless link for communication between first and second electronic devices mounted to a vehicle;
receiving a signal transmitted over the wireless link;
displaying a power level of the received signal; and
adjusting an alignment of the first or second antenna to increase the displayed power level and substantially align a linear polarization component of the first or second antenna to a lateral axis of the vehicle.

11. The method of claim 10 , wherein:
the adjusting the alignment of the first antenna comprises adjusting a mounting of the first electronic device to the vehicle; and
the adjusting the alignment of the second antenna comprises adjusting a mounting of the second antenna to the vehicle.

12. The method of claim 10 , further comprising:
forming, using at least a third antenna, at least another wireless link for communication between a third electronic device and the first or second device, wherein the third electronic device is in proximity to the vehicle;
receiving at least another signal transmitted over the at least another wireless link;
displaying at least another power level of the received at least another signal; and
adjusting an alignment of the third antenna to increase at least one of the displayed power levels and substantially align a linear polarization component of the third antenna to a lateral axis of the vehicle.

13. The method of claim 12 , wherein:
the adjusting the alignment of the third antenna comprises adjusting a position or orientation of the third electronic device.

14. The method of claim 12 , wherein:
the first and third devices are in communication over the at least another wireless link; and
the second and third devices are in communication over the wireless link and the at least another wireless link.

15. The method of claim 12 , wherein:
the forming the at least another wireless link comprises forming two wireless links;
the first and third devices are in communication over at least a first one of the two wireless links; and
the second and third devices are in communication over at least a second one of the two wireless links.

16. A method comprising:
forming, using first and second antennas, a wireless link for communication between a sensor mounted to a vehicle and a user interface mounted to the vehicle, wherein linear polarization components of the first and second antennas are substantially aligned with a lateral axis of the vehicle;
receiving a sensor signal transmitted over the wireless link; and
displaying, by the user interface, sensor information corresponding to the received sensor signal.

17. The method of claim 16 , wherein:
the sensor comprises a wind sensor, a water speed sensor, an orientation sensor, a GPS, a gyroscope, an accelerometer, a temperature sensor, a barometer, or a steering sensor.

18. The method of claim 16 , further comprising:
forming, using at least a third antenna, at least another wireless link for communication between another sensor mounted to the vehicle and the sensor or the user interface, wherein a linear polarization component of the third antenna is substantially aligned with a lateral axis of the vehicle;
receiving at least another sensor signal transmitted over the at least another wireless link; and
displaying, by the user interface, sensor information corresponding to the received at least another sensor signal.

19. The method of claim 18 , wherein:
the first and third devices are in communication over the at least another wireless link; and
the second and third devices are in communication over the wireless link and the at least another wireless link.

20. The method of claim 18 , wherein:
the forming the at least another wireless link comprises forming two wireless links;
the sensor and the another sensor are in communication over at least a first one of the two wireless links; and
the user interface and the another sensor are in communication over at least a second one of the two wireless links.
