Abstract: Methods, systems, and articles of manufacture consistent with certain aspects related to the present invention collect item information from RFID tags attached to items in an inventory, and uses the collected item information to perform various inventory management processes. In one aspect, the inventory management processes may include determining, reporting, and/or providing corrective actions for one or more events associated with at least one of depletions of items in the inventory, changes in the design of items in the inventory, defects with one or more items, misplaced items, the movement of an unusual number of items within a short period of time (i.e., shrinkage), and malfunctions of one or more components included in the environment.

Abstract: A security system including a security tag is provided. The security tag includes a housing and a pin in which the pin is removably insertable into the housing. The security tag further includes a latching element disposed within the housing and positionable in a lock position and in an unlock position. The latching element includes a pivot axis. The latching element has a substantially balanced rotational response about the pivot axis when exposed to an external physical mechanical impulse. The security tag further includes a bias element that releasably positions the latching element in the lock position. The latching element releasably engages the inserted pin when in the lock position.

Abstract: In accordance with preferred embodiments of the invention, a method (and corresponding apparatus) is provided for deducing the location of one or more items or objects to be monitored. In exemplary embodiments, the method (and corresponding apparatus) is implemented in RFID (radio frequency identification) applications (e.g., reading RFID tags at 13.56 MHz and approximately 900 MHz) by deducing the location of an item associated with a unique RFID tag in one or more areas of detection covered by multiple RFID reader antennae.
