Abstract

Methods and systems for optimizing information associated with RFID devices that, include a memory chip written with redundant data and read by an RFID reader and, are adapted for operation of RFID tags and chemical, biological, and physical RFID sensors that are exposed to gamma radiation, such as disposable devices used in bioprocessing.

Claims

1. A method for optimizing information associated with an RFID device at least in part using an RFID reader, wherein the RFID device comprises a memory chip written with at least one redundant set of data;

comprising the steps of,

reading at least a portion of at least one the redundant data sets on the memory chip of the RFID device; and

comparing at least the portion of the redundant data set read from the chip with another set of data on the chip.

2. The method of claim 1, further comprising the step of comparing at least one of the redundant data sets read from the chip to eliminate effects of gamma radiation on the RFID device.

3. The method of claim 1, further comprising the step of, determining whether the RFID device has been exposed to radiation by determining that at least part of the data on the chip is corrupted.

4. The method of claim 3, further comprising the step of, correcting at least part of the corrupted data.

5. The method of claim 1, wherein the RFID reader is at a predetermined distance from the RFID device, further comprising the steps of, determining whether a post-reading distance between the RFID reader and the RFID device varies from the predetermined distance;

and adjusting a power level of the reader based at least in part on a variation between the predetermined distance and the post-reading distance.

6. The method of claim 5, further comprising the step of, determining whether the RFID device has been exposed to radiation by determining that at least part of the data on the chip is corrupted.

7. The method of claim 1, further comprising the step of, determining whether at least part of the data on the chip is corrupted.

8. The method of claim 7, further comprising the step of, correcting at least part of the corrupted data.

9. The method of claim 1, determining whether at least part of the data on the chip is corrupted by evaluating one or more performance characteristics of one or more CMOS components of the memory chip.

10. The method of claim 1, further comprising the step of, adjusting a power level of the reader.

11. The method of claim 1, further comprising the steps of, deleting one or more whole or partial redundant sets of data in the memory of the chip.

12. The method of claim 1, wherein the RFID device is an RFID sensor.

13. The method of claim 1, wherein the RFID device is an RFID tag.

14. The method of claim 1, authenticating the RFID device at least in part based on the step of comparing the redundant data read from the chip.

15. A method for optimizing information associated with an RFID device at least in part using an RFID reader, wherein the RFID device comprises a memory chip written with at least one redundant set of data and;

comprising the steps of,

reading at least a portion of at least one the redundant data sets on the memory chip of the RFID device;

adjusting a power level of the reader and comparing at least one of the redundant data sets read from the chip.

16. The method of claim 15, further comprising the step of, deleting one or more partial or whole sets of data in the memory of the chip.

17. The method of claim 15, further comprising the steps of, determining whether any of the data has been corrupted, and correcting at least part of the corrupted data.

18. The method of claim 15, authenticating the RFID device at least in part based on the step of comparing the redundant data read from the chip.

19. A system for optimizing information between RFID components, comprising,

an RFID device comprising a memory chip written with at least one redundant set of data;

an RFID reader that is a predetermined distance from the RFID device; and

an operating subsystem that;

initiates the reader to read at least a portion of at least one the redundant data sets on the memory chip of the RFID device; and

compares at least one of the redundant data sets read from the chip.

20. The system of claim 19, wherein the operating subsystem further adjusts a power level of the reader based at least in part on a variation between the predetermined distance and the post-reading distance

21. The system of claim 19, wherein the operating system further deletes one or more whole or partial redundant sets of data in the memory of the chip.

22. The system of claim 19, wherein the RFID device is an RFID sensor.

23. The system of claim 19, wherein the RFID device is an RFID tag.

24. The system of claim 19, wherein the operating system further authenticates the RFID device at least in part based on the comparison of the redundant data read from the chip.

25. The system of claim 19, wherein the operating system further determines whether the RFID device has been exposed to gamma radiation at least in part by the comparison of at least one of the redundant data sets read from the chip

26. The system of claim 19, wherein the operating system further determines that the RFID device has been exposed to gamma radiation by determining whether any of the data has been corrupted, and corrects at least part of the corrupted data.

27. The system of claim 19, wherein the operating system further determines whether any of the data has been corrupted, and corrects at least part of the corrupted data.
