Abstract

A ribbon comprises a substrate, and a plurality of seals on the substrate. Different seals detune in response to differing tensile loads. At least one of the seals comprises a surface acoustic wave (SAW) radio frequency identification (RFID) seal.

Claims

1. A ribbon comprising:

a substrate; and

a plurality of seals on the substrate, different seals detuning in response to differing loads, wherein at least one of the seals comprises a surface acoustic wave (SAW) radio frequency identification (RFID) seal.

2. The ribbon of claim 1, wherein each seal detunes in response to a differing load.

3. The ribbon of claim 2, wherein the SAW RFID seal comprises at least one antenna, an inter-digital transducer (IDT) and at least one set of reflectors.

4. The ribbon of claim 3, wherein the IDT comprises two arrays each comprising six electrodes.

5. The ribbon of claim 3, wherein at least one of the reflectors is used for calibration.

6. The ribbon of claim 3, wherein at least one of the reflectors is used for error correction.

7. The ribbon of claim 3, wherein the antenna outputs a signature in response to a scanning signal.

8. The ribbon of claim 3, wherein the SAW RFID seal comprises a first antenna configured to receive a scanning signal and a second antenna configured to output an identification (ID) of the SAW RFID seal.

9. The ribbon of claim 7, wherein the scanning signal ranges from about 860 to 960 MHz.

10. The ribbon of claim 7, wherein the scanning signal is any one of about 300 KHz, 13.56 MHz, 30 MHz, 433 MHz, 2.4 GHz, 5.6 GHz and 12.9 GHz.

11. The ribbon of claim 1, wherein at least another of the plurality of seals is an RFID seal.

12. The ribbon of claim 11, wherein the RFID seal comprises an antenna and a tag tuned to said antenna, said tag becoming detuned in response to said differing load.

13. The ribbon of claim 12, wherein each tag outputs a signature in response to a scanning signal when tuned to said respective antenna.

14. The ribbon of claim 13, wherein each tag resonates in response to said scanning signal when tuned to said respective antenna and outputs a code unique to said tag.

15. The ribbon of claim 14, wherein said scanning signal is of a predetermined frequency.

16. The ribbon of claim 12, wherein each antenna comprises 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 in response to said differing load.

17. The ribbon of claim 16, wherein said at least one break-away portion is coupled to said main antenna portion by one-time contacts.

18. The ribbon of claim 16, comprising a plurality of break-away portions at spaced along locations along the antenna.

19. The ribbon of claim 11, wherein the RFID seal is a passive RFID seal.

20. The ribbon of claim 1, wherein the load is selected from the group comprising tensile, parallel, perpendicular and longitudinal loads.
