Abstract
A device for tracking an item or a box may include a conductive mesh configured to at least partially cover the item or the box, and a wireless tag coupled to the conductive mesh. The wireless tag may be configured to report a breaching of the conductive mesh or an opening of the box by issuing a first predetermined RF signal. The wireless tag may include a GPS device and the first predetermined signal may include GPS-derived geographical information.

15. A method of tracking an item, the method comprising the steps of:
-
providing a conductive mesh; providing a wireless tag and coupling the wireless tag to the conductive mesh such that removal of the wireless tag from the conductive mesh disables the wireless tag, the wireless tag being configured to wirelessly report a state of the conductive mesh by selectively issuing a first or a second predetermined RF signal; covering at least a portion of the item with the conductive mesh; and periodically receiving the first or second predetermined RF signal from the wireless tag coupled to the conductive mesh. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of remotely determining if an item has been added to or removed from a container, the method comprising the steps of:
-
providing a conductive mesh to which is coupled a wireless tag, the wireless tag and the conductive mesh being configured such that removal of the wireless tag from the conductive mesh disables the wireless tag, the wireless tag being configured to wirelessly report a state of the conductive mesh by selectively issuing a first or a second predetermined RF signal; sealing the container with the conductive mesh; and periodically receiving the first or second predetermined RF signal from the wireless tag coupled to the conductive mesh, wherein receipt of the first predetermined RF signal indicating that no item has been added to or removed from the container and wherein receipt of the second predetermined RF signal indicating that an item may have been added to and/or removed from the container and wherein non-receipt of either the first or the second predetermined RF signals indicating that the wireless tag may have been disabled. - View Dependent Claims (31, 32)
