Abstract

A device includes a desiccant and an enclosure having an interior surrounding the desiccant. The enclosure may include a moisture vapor permeable membrane with a moisture permeability sufficient to pass moisture from outside the enclosure to the desiccant. The device may further include a functional device within the enclosure having processing circuitry to perform at least one function associated with the desiccant.

Claims

1. A device comprising:

a desiccant;

an enclosure having an interior surrounding the desiccant and including a moisture vapor permeable membrane with a moisture permeability sufficient to pass moisture from outside the enclosure to the desiccant; and

a functional device within the enclosure including processing circuitry to perform at least one function associated with the desiccant, wherein the functional device is configured to control operation of the desiccant by controlling an interaction of the desiccant with an environment outside the enclosure, and wherein the functional device controls a physical exposure of the desiccant to the environment in a manner that varies over time.

2. The device of claim 1 wherein the functional device includes a sensor.

3. The device of claim 2 wherein the sensor detects contents of a container holding the enclosure.

4. The device of claim 2 wherein the sensor detects one or more environmental conditions.

5. The device of claim 1 wherein the functional device stores a unique identifier for the device.

6. The device of claim 5 wherein the processing circuitry includes a wireless communication system configured to transmit the unique identifier to a remote location.

7. The device of claim 1 wherein the processing circuitry includes an RFID tag.

8. The device of claim 1 wherein the processing circuitry includes communications circuitry for one or more of near field communications, short range wireless communications, low power wireless communications, and communications with a global positioning satellite.

9. The device of claim 1 wherein the processing circuitry includes a sensor and communications circuitry.

10. The device of claim 9 wherein the sensor is configured to detect a status of an item and provide status information corresponding to the status of the item.

11. The device of claim 9 wherein the sensor is configured to detect a condition of an environment around the enclosure.

12. The device of claim 11 wherein the condition is one or more of a humidity and a temperature.

13. The device of claim 9 wherein the communications circuitry is configured to transmit data obtained from the sensor.

14. The device of claim 1 wherein the functional device includes a sensor configured to detect a humidity in an area around the enclosure and a controller configured to variably control the physical exposure of the desiccant in response to a control signal, the processing circuitry configured to adjust the control signal in response to the humidity.

15. The device of claim 14 wherein the functional device detects one or more other conditions for use in combination with the humidity to adjust the control signal.

16. The device of claim 1 wherein the functional device controls the physical exposure of the desiccant according to a predetermined schedule.

17. The device of claim 1 wherein the functional device controls a temperature of the desiccant or an agitation of the desiccant.

18. The device of claim 1 wherein the processing circuitry of the functional device is configured to alter contents of a container holding the enclosure upon occurrence of a predetermined event.

19. The device of claim 18 wherein altering the contents includes one or more of adding a destabilizing agent to the contents, adding a pigment to the contents, adding an odor to the contents, adding a toxin to the contents, adding a solvent to the contents, and heating the contents.

20. The device of claim 18 wherein the predetermined event includes a passage of time.

21. The device of claim 18 wherein the predetermined event includes a failure to receive an authorization within a predetermined time.

22. The device of claim 18 wherein the predetermined event includes receipt of a remote signal.

23. The device of claim 18 wherein the predetermined event includes a movement of the device outside a geofence.

24. The device of claim 1 wherein the functional device includes a signaling device.

25. The device of claim 24 wherein the signaling device provides one or more of an audible sound, a vibration, or an illumination.

26. The device of claim 25 wherein the signaling device provides a signal in response to an internal condition of a container holding the enclosure.

27. The device of claim 26 wherein the internal condition is an expiration of contents of the container.

28. The device of claim 24 wherein the signaling device provides a signal in response to an external condition of a container holding the enclosure.

29. The device of claim 28 wherein the external condition includes one or more of temperature, humidity, time, pressure, and vibration.

30. The device of claim 28 wherein the external condition is transmitted to the functional device from a remote source.

31. A device comprising:

a desiccant;

an enclosure having an interior surrounding the desiccant and including a moisture vapor permeable membrane with a moisture permeability sufficient to pass moisture from outside the enclosure to the desiccant; and

a functional device coupled to an exterior of the enclosure including processing circuitry to perform at least one function associated with the desiccant, wherein the functional device is configured to control operation of the desiccant by controlling an interaction of the desiccant with an environment outside the enclosure, and wherein the functional device controls a physical exposure of the desiccant to the environment in a manner that varies over time.
