Abstract

A radio frequency identification seal comprises an antenna including a main antenna portion and at least one break-away portion and an RFID tag coupled and tuned to the antenna. The RFID tag outputs a signature in response to a scanning signal when tuned to the antenna.

Claims

1. A container comprising:

a container body; and

a passive seal on at least a portion of said container body, said seal including an antenna and a tag tuned to said antenna, said tag becoming detuned when said antenna is compromised during opening of said container,

wherein said antenna includes a main antenna portion and at least one break-away portion coupled to said main antenna portion, said at least one break-away portion separating from said main antenna portion when said container is opened resulting in said tag becoming detuned from said antenna.

2. A container according to claim 1 wherein said tag outputs a signature in response to a scanning signal when tuned to said antenna.

3. A container according to claim 2 wherein said tag resonates in response to said scanning signal when tuned to said antenna and outputs a code unique to said tag.

4. A container according to claim 3 wherein said scanning signal is of a predetermined frequency.

5. A container according to claim 1 wherein said at least one break-away portion is coupled to said main antenna portion by one-time contacts.

6. A container according to claim 5 wherein said main antenna portion is provided on a door of said container and wherein said at least one break-away portion is provided on a doorjamb of said container.

7. A container according to claim 5 comprising a plurality of break-away portions at spaced locations along said antenna.

8. A container according to claim 7 wherein said main antenna portion is provided on a door of said container and wherein at least one of said break-away portions is provided on a doorjamb of said container.

9. A container according to claim 8 wherein another of said break-away portions is provided adjacent a lock on said door.

10. A container according to claim 5 wherein said tag and antenna are disposed on a substrate secured to said container.

11. A container according to claim 10 wherein said substrate is adhered to said container.

12. A radio frequency identification seal according to claim 11 wherein said at least one break-away portion is coupled to said main antenna portion by one-time contacts.

13. A radio frequency identification seal according to claim 12 comprising a plurality of break-away portions.

14. A passive radio frequency identification seal comprising:

an antenna including a main antenna portion and at least one break-away portion coupled to said main antenna portion; and

a radio frequency identification (RFID) tag coupled and tuned to said antenna, said RFID tag outputting a signature in response to a scanning signal when tuned to said antenna,

wherein said antenna is affixable to a container such that said at least one break-away portion separates from said main antenna portion when said container is opened resulting in said RFID tag becoming detuned from said antenna.

15. A radio frequency identification seal according to claim 14 wherein said RFID tag outputs a unique code in response to said scanning signal.

16. A system for monitoring at least one radio frequency identification (RFID) seal affixed to a vehicle, the system comprising:

at least one passive RFID seal comprising;

an antenna including a main antenna portion and at least one break-away portion coupled to said main antenna portion; and

an RFID tag coupled and tuned to the antenna, said RFID tag outputting a signature in response to a scanning signal when tuned to said antenna; and

at least one RFID reader mounted on structure by which the vehicle passes, the at least one RFID reader outputting the scanning signal and receiving the signature,

wherein said at least one break-away portion separates from said main antenna portion when said antenna is compromised resulting in said RFID tag becoming detuned from said antenna.

17. The system of claim 16, further comprising a wireless transmitter mounted on the structure for transmitting the signature to a central location for verification.

18. The system of claim 16, wherein the structure is one of a highway entrance gate, a roadway lighting pole, an entrance gate to a yard and an exit gate from a yard.

19. The system of claim 16, wherein the vehicle is one of a truck, aircraft, automobile and shipping vessel.

20. The system of claim 16 wherein said RFID tag resonates in response to said scanning signal when tuned to said antenna and outputs a code unique to said RFID tag.

21. The system of claim 20 wherein said scanning signal is of a predetermined frequency.

22. The system of claim 20 wherein said at least one break-away portion is coupled to said main antenna portion by one-time contacts.

23. A structural material comprising:

at least one passive radio frequency identification (RFID) seal affixed to the structural material at a location prone to fatigue such that said at least one passive RFID seal spans portions of said structural material that move relative to one another upon fatigue, the at least one passive RFID seal comprising;

an antenna including a main antenna portion and at least one break-away portion coupled to said main antenna portion; and

an RFID tag coupled and tuned to the antenna, said RFID tag outputting a signature in response to a scanning signal when tuned to said antenna,

wherein when the structural material undergoes fatigue adjacent said location and said structural material portions move relative to one another, the at least one break-away portion separates from the main antenna portion to detune the at least one passive RFID seal.

24. The structural material of claim 23, wherein the structural material forms part of one of a wing of an airplane, a fuselage of an airplane, a tail of an airplane, landing gear of an airplane, a longeron of an airplane, a spar of an airplane, a rib of an airplane, an undercarriage of an airplane, a boom of a crane, a main trunnion support of a crane, a counterweight of a crane, a welding point of a crane, a lifting harness of a crane, a main span of a bridge, a pad bearing of a bridge, a parapet of a bridge, an expansion joint of a bridge, road decking of a bridge, a submersible support of a drilling rig, a bridge footing, a bridge/pier fastening, strapping, an anchor, a boiler, a nuclear fuel rod casement, a railway dolly assembly, a blade of a wind turbine, a spindle of a wind turbine, a stanchion of a wind turbine and a vessel.

25. The structural material of claim 23, wherein fatigue is selected from the group consisting of:

cracks, protrusions, chevron buckling, hair-line fractures, corrosion notching, skin notching, skin stiffness and strain creep.

26. The structural material of claim 24, wherein fatigue is selected from the group consisting of:

cracks, protrusions, chevron buckling, hair-line fractures, corrosion notching, skin notching, skin stiffness and strain creep.

27. The structural material of claim 23 wherein said RFID tag resonates in response to said scanning signal when tuned to said antenna and outputs a code unique to said RFID tag.
