Abstract

An interrogation system and method of operating the same. In one embodiment, the interrogation system includes a structure having a plurality of modules and a washer located within one of the plurality of modules including a radio frequency identification (RFID) tag with a code. The interrogation system also includes an interrogator configured to read the RFID tag and discern a type of structure based on information about the plurality of modules from the code.

Claims

1. An interrogation system, comprising:

a structure, including;

a plurality of modules, and

a washer located within one of said plurality of modules including a radio frequency identification (RFID) tag with a code; and

an interrogator configured to read said RFID tag and discern a type of said structure based on information about said plurality of modules from said code.

2. The interrogation system as recited in claim 1 wherein said structure includes another washer located within another one of said plurality of modules including another RFID tag with another code, said interrogator configured to read said another RFID tag and discern a type of said structure based on information about said plurality of modules from said code and said another code.

3. The interrogation system as recited in claim 1 wherein said structure is a weapon.

4. The interrogation system as recited in claim 1 wherein said plurality of modules include a fuse, seeker, warhead, and guidance and control module.

5. The interrogation system as recited in claim 1 wherein said washer is cylindrical.

6. The interrogation system as recited in claim 1 wherein said washer is selected from the group consisting of:

a flat washer,

a split washer,

a blind mate coupler, and

a flange.

7. The interrogation system as recited in claim 1 wherein said washer includes an antenna for said RFID tag.

8. The interrogation system as recited in claim 1 wherein said washer includes another identifier.

9. The interrogation system as recited in claim 1 wherein said interrogator includes a sensor configured to measure a characteristic of said structure.

10. The interrogation system as recited in claim 1 wherein said interrogator includes a transmitter, a receiver and a controller.

11. An interrogation system, comprising:

a structure including a plurality of sections, each of said plurality of sections including a radio frequency identification (RFID) tag; and

an interrogator within said structure configured to read said RFID tags and discern a location of said interrogator within said structure.

12. The interrogation system as recited in claim 11 wherein said interrogator is configured to read said RFID tags and discern a time associated therewith.

13. The interrogation system as recited in claim 11 wherein said interrogator tests a property of said structure.

14. The interrogation system as recited in claim 11 wherein said interrogator tests an integrity of said structure by sensing a temperature of said structure.

15. The interrogation system as recited in claim 11 wherein said structure is a pipeline.

16. A method of operating an interrogation system, comprising:

providing a structure including a plurality of modules and a washer located within one of said plurality of modules including a radio frequency identification (RFID) tag with a code;

reading said RFID tag; and

discerning a type of said structure based on information about said plurality of modules from said code.

17. The method as recited in claim 16 wherein said structure includes another washer located within another one of said plurality of modules including another RFID tag with another code, said method further comprising reading said another RFID tag and discerning a type of said structure based on information about said plurality of modules from said code and said another code.

18. The method as recited in claim 16 wherein said structure is a weapon.

19. The method as recited in claim 16 wherein said plurality of modules include a fuse, seeker, warhead, and guidance and control module.

20. The method as recited in claim 16 wherein said washer is cylindrical.

21. The method as recited in claim 16 wherein said washer is selected from the group consisting of:

a flat washer,

a split washer,

a blind mate coupler, and

a flange.

22. The method as recited in claim 16 wherein said washer includes an antenna for said RFID tag.

23. The method as recited in claim 16 wherein said washer includes another identifier.

24. The method as recited in claim 16 further comprising measuring a characteristic of said structure.

25. The method as recited in claim 16 wherein said interrogator includes a transmitter, a receiver and a controller.
