Abstract

A wireless (e.g., near field or RF) communication device, and methods of manufacturing and using the same are disclosed. The wireless communication device includes a receiver and/or transmitter, a substrate with an antenna thereon, an integrated circuit, and one or more protection lines. The antenna receives and/or transmits or broadcasts a wireless signal. The integrated circuit processes the wireless signal and/or information therefrom, and/or generates the wireless signal and/or information therefor. The integrated circuit has a first set of terminals electrically connected to the antenna. The protection line(s) are on a common or different substrate as the antenna. The protection line(s) sense or determine a continuity state of a package or container on which the communication device is placed or to which the communication device is fixed or adhered, and are electrically connected to a second set of terminals of the integrated circuit different from the first set of terminals.

Claims

1. A wireless communication device, comprising:

a) a receiver and a transmitter;

b) a substrate with an antenna thereon, the antenna receiving a first wireless signal and transmitting or broadcasting a second wireless signal;

c) an integrated circuit comprising (i) a continuity sensor and (ii) a memory and having a first set of terminals electrically connected to the antenna, the integrated circuit configured to (i) process the first wireless signal and/or information therefrom, and (ii) generate the second wireless signal and/or information therefor; and

d) one or more protection lines on a common or different substrate, the protection line(s) being (i) configured to sense or determine a continuity state of a package or container on which the communication device is placed or to which the communication device is fixed or adhered, and (ii) electrically connected to the continuity sensor through a second set of terminals of the integrated circuit different from the first set of terminals,

wherein the memory includes a first plurality of bits storing a value corresponding to the continuity state of the container or package, breaking at least one of the one or more protection lines causes the first plurality of the bits of data to change, and the second wireless signal communicates the value corresponding to the continuity state of the container or package.

2. The wireless communication device of claim 1, wherein the one or more protection lines comprises a plurality of the protection lines.

3. The wireless communication device of claim 1, wherein the integrated circuit comprises one or more printed layers and one or more thin films.

4. The wireless communication device of claim 1, wherein the antenna and the one or more protection lines consist of a single common metal layer on a common substrate.

5. The wireless communication device of claim 1, comprising a near field and/or radio frequency communication device.

6. The wireless communication device of claim 1, wherein the integrated circuit further comprises a second sensor.

7. The wireless communication device of claim 1, wherein the substrate comprises a plastic film or a plastic sheet that is scored to facilitate breaking the one or more protection lines when the container or package is opened.

8. The wireless communication device of claim 1, wherein the integrated circuit further comprises a threshold comparator configured to receive an output of the continuity sensor and having a comparator output that is stored in the memory, one or more bit lines for reading data from the memory, one or more sense amplifiers that convert signals on the one or more bit lines to digital signals, and one or more latches that temporarily store data from the one or more sense amplifiers.

9. The wireless communication device of claim 1, wherein the memory further comprises a second plurality of bits configured to store a unique identification code for the container or package, and a third plurality of bits configured to store overhead data.

10. The wireless communication device of claim 1, wherein the continuity state of the package or container is opened when at least one of the one or more protection lines is broken, the continuity state of the package or container is closed or sealed when each of the one or more protection lines is not broken, and the one or more bits configured to store the value corresponding to the continuity state of the container or package can be changed from a first value when the continuity state is closed or sealed to a second value when the continuity state is opened.

11. The wireless communication device of claim 10, wherein the memory contains 24 or more bits of data, and stores (i) a first ID for the device when the value of the first plurality of bits corresponds to a closed or sealed continuity state and (ii) a second ID for the device different from the first ID when the value of the first plurality of bits corresponds to an opened continuity state.

12. A package or container, comprising:

a) first and second separable parts with an interface therebetween; and

b) the wireless communication device of claim 1, on the first and second separable parts of the package or container, and over the interface.

13. The package or container of claim 12, wherein the integrated circuit and the antenna are on the first separable part of the package or container, and the one or more protection lines are on each of the first and second separable parts of the package or container.

14. The package or container of claim 12, wherein the package or container comprises multiple sealed or closed compartments, the one or more protection lines comprises a plurality of the protection lines, and each of the plurality of protection lines extends over a unique one of the multiple sealed or closed compartments.

15. A method of detecting an opened package or container, comprising:

a) placing the wireless communication device of claim 1 on the package or container such that at least one of the protection line(s) are over an interface between first and second separable parts of the package or container; and

b) using the integrated circuit, sensing a continuity state of the package or container.

17. The method of claim 15, wherein the integrated circuit and the antenna are on the first separable part of the package or container, and the one or more protection lines are on each of the first and second separable parts of the package or container.

18. The method of claim 15, wherein the one or more protection lines comprises a plurality of the protection lines.

19. A system, comprising:
