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.

wherein the memory includes one or more bits configured to store a value corresponding to the continuity state of the container or package, and the second wireless signal communicates the value of the continuity state of the container or package.

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

3. The wireless communication device of claim 1, further comprising one or more redundant protection lines.

4. The wireless communication device of claim 1, wherein the integrated circuit comprises one or more printed layers.

6. The wireless communication device of claim 1, wherein the antenna consists of a single metal layer.

7. The wireless communication device of claim 6, wherein the antenna and the one or more protection lines consist of a single common metal layer on a common substrate.

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

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

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 1, wherein the substrate comprises a plastic film or a plastic sheet.

12. The wireless communication device of claim 11, wherein the substrate is scored to facilitate breaking the one or more protection lines when the container or package is opened.

13. 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, 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;

and an output of the threshold comparator is stored in the memory.

14. The wireless communication device of claim 1, wherein the memory further comprises a first plurality of bits configured to store a unique identification code for the container or package, and the first plurality of bits comprise printed memory.

15. The wireless communication device of claim 14, wherein the memory further comprises a second plurality of bits configured to store overhead data.

16. The wireless communication device of claim 1, wherein the memory contains 8 or more bits of data, and breaking one of the one or more protection lines causes a plurality of the bits of data in the memory to change.
