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.
Claims29
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.

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.
1 more element
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.
4 more elements
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.
