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.

First claim

What is claimed is:

1. A wireless communication device, comprising:
a) a receiver and a transmitter;
b) a substrate with an antenna thereon, said antenna receiving a first wireless signal and transmitting or broadcasting a second wireless signal;
c) an integrated circuit configured to (i) process said first wireless signal and/or information therefrom, and (ii) generate said second wireless signal and/or information therefor, said integrated circuit comprising a continuity sensor, a memory, a first set of terminals electrically connected to said antenna, and a second set of terminals electrically connected to said continuity sensor, said second set of terminals being different from said first set of terminals; and
d) one or more protection lines connected to said second set of terminals, the protection line(s) being 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,
wherein:
the memory includes one or more dynamic sensor bits configured to store a value corresponding to the continuity state of the container or package,
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,
the one or more dynamic sensor bits is/are changed from a first value when the continuity state is closed or sealed to a second value when the continuity state is opened, 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 , comprising a near field and/or radio frequency communication device.

3. The wireless communication device of claim 1 , wherein the integrated circuit further comprises a threshold comparator receiving an output of said continuity sensor, and an output of the threshold comparator is stored in the memory as the one or more dynamic sensor bits.

4. The wireless communication device of claim 1 , wherein the integrated circuit further comprises one or more bit lines for reading data from the memory, and one or more sense amplifiers that convert signals on the one or more bit lines to digital signals.

5. The wireless communication device of claim 4 , wherein the integrated circuit further comprises one or more latches that temporarily store data from the one or more sense amplifiers.

6. The wireless communication device of claim 1 , wherein the memory further comprises a first plurality of bits configured to store a unique identification code.

7. The wireless communication device of claim 6 , wherein the memory further comprises a second plurality of bits configured to store overhead data.

8. The wireless communication device of claim 7 , wherein the memory contains at least 256 bits of data.

9. A package or container, comprising:
a) first and second separable parts with an interface therebetween; and
b) wireless communication device of claim 1 , wherein the one or more protection lines is/are on the first and second separable parts of the package or container and over the interface.

10. The package or container of claim 9 , wherein the integrated circuit and the antenna are on the first separable part of the package or container.

11. A wireless communication device, comprising:
a) a receiver comprising a demodulator and a transmitter comprising a modulator;
b) a substrate with an antenna thereon, said antenna receiving a first wireless signal and transmitting or broadcasting a second wireless signal;
c) an integrated circuit configured to (i) process said first wireless signal and/or information therefrom, and (ii) generate said second wireless signal and/or information therefor, said integrated circuit comprising:
i) a continuity sensor,
ii) a memory,
iii) a first set of terminals electrically connected to said antenna, and
iv) a second set of terminals electrically connected to said continuity sensor, said second set of terminals being different from said first set of terminals; and

d) one or more protection lines connected to said second set of terminals, the protection line(s) being 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,
wherein:
the memory includes one or more sensor bits configured to store a value corresponding to the continuity state of the container or package,
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,
the one or more sensor bits is/are changed from a first value when the continuity state is closed or sealed to a second value when the continuity state is opened,
the wireless communication device is configured such that it recognizes a change in the value of the continuity state and provides (i) a first consumer and/or user experience through the wireless communication device when the value of the continuity state of the container or package corresponds to a closed or sealed continuity state and (ii) a different consumer and/or user experience through the wireless communication device when the continuity state of the container or package corresponds to an opened continuity state, and
the second wireless signal communicates the value of the continuity state of the container or package.

12. The wireless communication device of claim 11 , comprising a near field and/or radio frequency communication device.

13. The wireless communication device of claim 11 , wherein the integrated circuit further comprises a threshold comparator receiving an output of said continuity sensor, and an output of the threshold comparator is stored in the memory as the one or more sensor bits.

14. The wireless communication device of claim 11 , wherein the receiver comprises a demodulator, and the transmitter comprises a modulator.

15. The wireless communication device of claim 14 , wherein the integrated circuit further comprises a clock configured to provide a timing signal that controls a timing of a plurality of operations in the integrated circuit.

16. The wireless communication device of claim 11 , wherein the memory further comprises a first plurality of bits configured to store a unique identification code.

17. The wireless communication device of claim 16 , wherein the memory further comprises a second plurality of bits configured to store overhead data.

18. The wireless communication device of claim 17 , wherein the memory contains at least 256 bits of data.

19. The wireless communication device of claim 11 , wherein after the one or more sensor bits is/are changed from the first value to the second value, it is impossible for the first value to be read.

20. The wireless communication device of claim 11 , wherein after the second wireless signal communicates the second value indicating an opened continuity state, an alert is automatically triggered when the second wireless signal communicates the first value indicating a closed continuity state.
