Abstract: An electronic security tag system comprising a security anchor having an aperture therethrough and a plurality of flexible wings extending outward. There is an adhesive layer attached to the bottom surface of the anchor for adhering the anchor to the article. A security wire is threaded through the aperture in the anchor and is held securely within the aperture of the anchor. A PC board having a diode is connected to an end of the security wire threaded through the aperture. A flexible adhesive tag is connected to the PC board. The tag has a circuit wired therethrough which is connected via the PC board to the diode. The security wire is connected to an electronic security monitoring system having an audible alarm. Cutting the security wire or the circuit in the tag triggers the alarm.

Abstract: An article inventory control system for articles, such as books, uses RFID tags attached to each article. Each tag has a unique identification or serial number for identifying the individual article. An inventory database tracks all of the tagged articles and maintains circulation status information for each article. Articles are checked out of the library using a patron self-checkout system. Checked out articles are returned to the library via patron self-check in devices. The shelves are periodically scanned with a mobile RFID scanner for updating inventory status.

Abstract: A Pressure Sensitive Alarm Component is provided and includes a pressure plate and a base plate. Within the base plate are the pressure plate truss assemblies, the weight transfer assembly, and the sliding switch assembly. The weight transfer assembly includes a load transfer arm which moves back and forth as weight is placed on or removed from the pressure plate and a dial to adjust the position of the load transfer arm. The sliding switch assembly includes a sliding contact support arm which is rigidly linked to the load transfer arm. The sliding switch assembly further includes a plurality of stationary contacts incorporated into a base plate, and two sliding contacts mounted on the sliding contact support arm. The sliding contacts may move along the stationary contacts and open and close the control circuit as they come in out of contact with different pairs of stationary contacts.
