Abstract

A radio frequency identification (“RFID”) system and method of operating the same. In one embodiment, the RFID system includes a reader configured to transmit a command including a parameter profile of a product. The RFID system also includes a sensor tag configured to sense raw data associated with the product, process the raw data to create processed data as a function of the parameter profile and provide the processed data to the reader.

Claims

1. A radio frequency identification (RFID) system, comprising:

a reader configured to transmit a command including a parameter profile of a product; and

a sensor tag configured to sense raw data associated with said product, process said raw data to create processed data as a function of said parameter profile and provide said processed data to said reader.

2. The RFID system as recited in claim 1 further comprising a computer system configured to provide said parameter profile of said product to said reader.

3. The RFID system as recited in claim 1 wherein said reader is configured to provide said processed data to a computer system to determine if said processed data is within guidelines for said product.

4. The RFID system as recited in claim 1 wherein a transmitter/receiver of said sensor tag is configured to receive said command from said reader and provide said processed data to said reader.

5. The RFID system as recited in claim 1 wherein a processor of said sensor tag is configured to apply rules to process said raw data to create said processed data.

6. The RFID system as recited in claim 1 wherein a sensor of said sensor tag is configured to sense said raw data via a transducer thereof.

7. The RFID system as recited in claim 1 wherein a sensor of said sensor tag is configured to sense said raw data and is selected from the group consisting of:

an optical sensor,

a temperature sensor,

a pressure sensor, and

an accelerometer.

8. The RFID system as recited in claim 1 wherein a memory of said sensor tag includes information selected from the group consisting of:

tag identification,

said parameter profile of said product,

said processed data, and

said raw data.

9. The RFID system as recited in claim 1 wherein said parameter profile of said product is selected from the group consisting of:

a temperature profile of said product,

a shock profile of said product,

a voltage profile of said product,

a current profile of said product,

a humidity profile of said product,

a strain profile of said product,

a material stresses profile of said product,

an optical/light exposure profile of the product,

an emissions profile of the product,

a radiation/heat signature profile of the product, and

a viscosity profile of said product.

10. The RFID system as recited in claim 1 wherein a rate of providing said processed data to said reader is a function of an operating frequency of said sensor tag.

11. A method of operating a radio frequency identification (RFID) system, comprising:

transmitting a command including a parameter profile of a product from a reader;

sensing raw data associated with said product with a sensor tag;

processing said raw data to create processed data as a function of said parameter profile with said sensor tag; and

providing said processed data to said reader.

12. The method as recited in claim 11 further comprising providing said parameter profile of said product to said reader.

13. The method as recited in claim 11 further comprising determining if said processed data is within guidelines for said product.

14. The method as recited in claim 11 wherein a transmitter/receiver of said sensor tag receives said command from said reader and provides said processed data to said reader.

15. The method as recited in claim 11 wherein said processing applies rules to process said raw data to create said processed data.

16. The method as recited in claim 11 wherein a sensor of said sensor tag senses said raw data via a transducer thereof.

17. The method as recited in claim 11 wherein a sensor of said sensor tag senses said raw data and is selected from the group consisting of:

an optical sensor,

a temperature sensor,

a pressure sensor, and

an accelerometer.

18. The method as recited in claim 11 further comprising storing information on said sensor tag selected from the group consisting of:

tag identification,

said parameter profile of said product,

said processed data, and

said raw data.

19. The method as recited in claim 11 wherein said parameter profile of said product is selected from the group consisting of:

a temperature profile of said product,

a shock profile of said product,

a voltage profile of said product,

a current profile of said product,

a humidity profile of said product,

a strain profile of said product,

a material stresses profile of said product,

an optical/light exposure profile of the product,

an emissions profile of the product,

a radiation/heat signature profile of the product, and

a viscosity profile of said product.

20. The method as recited in claim 11 wherein a rate of providing said processed data to said reader is a function of an operating frequency of said sensor tag.
