Abstract

A remote sensor having a thermal transducer, an acoustic transducer, and a magnetic transducer. The remote sensor can communicate data from any of the transducers via any of three different communication links, which include an active RF transceiver, an IRDA transceiver, and an RF backscatter transceiver.

Claims

1. A remote sensor device that can be located remotely from and supply data to a receiving unit, the sensor device comprising:

a sensor housing;

a thermal sensor located in the sensor housing that determines the ambient temperature;

an acoustic sensor located in the sensor housing;

a magnetic sensor located in the sensor housing; and

control logic located in the sensor housing that obtains sensor data from the three sensors and communicates it to the receiving unit.

2. A device as defined in claim 1, wherein the communication to the receiving unit is via optical transmission of data.

3. A device as defined in claim 2, wherein the communication is via IRDA protocol.

4. A device as defined in claim 3, the device further including an IRDA transmitter.

5. A device as defined in claim 1, wherein the communication to the receiving unit is via RF transmission of data.

6. A device as defined in claim 5, the device further including an RF transmitter.

7. A device as defined in claim 6, wherein the device includes an antenna that includes at least a portion of a guitar string.

8. A device as defined in claim 1, wherein the communication to the receiving unit is via RF backscatter transmission of data.

9. A device as defined in claim 8, the device further including a patch antenna that can be controllably and selectably shorted to ground.

10. A device as defined in claim 1, wherein the communication to the receiving unit is via a selected one of three different communication links.

11. A device as defined in claim 10, wherein the three different communication links include an IRDA communication link.

12. A device as defined in claim 10, wherein the three different communication links include an active RF communication link.

13. A device as defined in claim 10, wherein the three different communication links include an RF backscatter communication link.

14. A device as defined in claim 10, wherein the three different communication links include an IRDA communication link, an active RF communication link, and an RF backscatter communication link.

15. A remote sensor device that can be located remotely from and supply data to a receiving unit, the sensor device comprising:

a sensor housing;

at least one type of sensor located in the sensor housing;

control logic located in the sensor housing that obtains sensor data from the at least one sensor;

a first communication link that can communicate sensor data to the receiving unit;

a second communication link that can communicate sensor data to the receiving unit; and

a third communication link that can communicate sensor data to the receiving unit;

wherein the control logic determines which communication link to use in communicating the sensor data to the receiving unit.

16. A device as defined in claim 15, wherein the at least one type of sensor is a thermal sensor.

17. A device as defined in claim 15, wherein the at least one type of sensor is a magnetic sensor.

18. A device as defined in claim 15, wherein the at least one type of sensor is an acoustic sensor.

19. A device as defined in claim 15, further including another type of sensor located in the sensor housing.

20. A device as defined in claim 19, further including a third type of sensor located in the sensor housing.

21. A device as defined in claim 20, wherein the three types of sensors are a thermal sensor, a magnetic sensor, and an acoustic sensor.

22. A device as defined in claim 15, wherein the first communication link is via optical transmission of data.

23. A device as defined in claim 22, wherein the first communication link is via IRDA protocol.

24. A device as defined in claim 23, the device further including an IRDA transmitter.

25. A device as defined in claim 15, wherein the second communication link is via RF transmission of data.
