Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

WHAT IS CLAIMED IS:

1. A method for compensating data readings from a sensor, comprising the steps of:
providing a sensor for producing data readings;
associating the sensor with an item to be monitored;
determining calibration coefficients for the sensor subsequent to the step of associating;
providing a memory in proximity to the sensor; and
storing the calibration constants determined in the step of determining in the memory.

2. The method of claim 1, further comprising the steps of;
providing an interrogator for reading data from the sensor and memory;
reading the calibration constants from the memory;
reading data from the sensor; and
modifying the data read from the sensor as a function of the calibration constants.

3. The method of claim 1, wherein the step of providing a memory comprises configuring a portion of a memory of an RFID device to store the calibration constants.

4. The method of claim 1 , where the step of providing a memory comprises associating a memory device with the sensor.

5. The method of claim 1 , wherein the step of providing a sensor comprises providing a surface acoustic wave (SAW) based sensor.

6. A self-compensating sensor, comprising
a physical parameter sensitive sensor configured for installation in association with an item to be monitored; and
a memory device
wherein said memory device is configured to store post installation derived calibration coefficients uniquely associated with said sensor.

7. The self-compensating sensor of claim 6, wherein said sensor is a surface acoustic wave (SAW) based sensor.

8. The self-compensating sensor of claim 6, wherein the memory device comprises a portion of a memory within an RFID device.

9. The self-compensating sensor of claim 6, wherein a portion of the memory of said memory device is configured to contain data uniquely identifying said sensor.

10. A method for monitoring tire related parameters, comprising the steps of:
providing a tire;
providing a sensor for producing an output signal responsive to at least one tire related parameter;
associating a memory device with a tire;
associating the sensor with the memory device;
deriving calibration constants unique to the sensor;
storing the calibration constants in the memory; and
modifying the output signal as a function of the stored calibration constants.

11. The method of claim 10, wherein the step of associating the sensor with a memory device comprises embedding the sensor and memory device in a tire patch.

12. The method of claim 10, wherein the step of associating the sensor and memory device with a tire comprises securing the tire patch to a portion of said tire.

13. The method of claim 10, wherein the step of associating the sensor and memory device with a tire comprises embedding the sensor and memory device in a portion of the tire.

14. The method of claim 11 , wherein the steps of deriving and storing are performed following the step of embedding.

15. The method of claim 12, wherein the steps of deriving and storing are performed following the step of securing.

16. The method of claim 13, wherein the steps of deriving and storing are performed following the step of embedding.
