Abstract: A system and method for controlling door-mounted or door-embedded antennas. An antenna, for example, an EAS or an RF antenna, sends interrogation signals which are received by markers located on merchandise within a range of detection, i.e., an "interrogation zone". Antennas that are mounted on or embedded in a door move along with the motion of the door. Thus, the interrogation zone covered by the antenna's magnetic field is continually changing with the movement of the door. The system and method of the present invention control door-mounted antennas by monitoring the motion of the door upon which the antenna is mounted, and by adjusting the size and breadth of the interrogation zone generated by the antenna accordingly. A processor within a control unit receives positional signals from a position sensor mounted on the moving door, determines whether the interrogation zone should be increased, decreased, shut off, or maintained, and transmits signals to the antenna or to an alarm device, the signal containing interrogation zone modification instructions.

Abstract: An electric motor, system and method for activating and deactivating an EAS article is disclosed. The electric motor has a stationary electromagnet having a center. The electric motor further has a platform located parallel to the electromagnet, wherein the platform rotates about a center concentric with the center of the electromagnet. The electric motor further has a first magnet with a first polarity located on the platform and a second magnet with a second polarity located on the platform radially opposite to the first magnet. The electric motor further has a commutator for periodically reversing current supplied to the electromagnet so as to produce a first magnetic field that interacts with the first and the second magnet and causes the platform to spin about its center. When the platform rotates, a second magnetic field for one of activation and deactivation of an EAS article is produced by the first and the second magnet.

Abstract: A radiofrequency identification (RFID) multiplexer, which may be in a network, interprets an RF signal from an RFED reader as RFE) tag interrogation data. A single cable directs an RF signal from the RFID reader and RF control signals and/or RF power through the multiplexer. An RF sampler may be coupled to the cable; and an RF detector detects the RF signal from the cable via the RF sampler. A data decoder decodes and interprets the RF signal as the RFID tag interrogation data and forwards the RFID tag interrogation data to a control logic circuit as a MUX channel-change command. The logic circuit and decoder may be combined in a microcontroller, and an RF backscatter modulator coupled to the cable enables reverse communication with the RFID reader to determine whether another RFID multiplexer is coupled to the RFID multiplexer.

Abstract: A security tag includes an EAS component having a defined surface area, and an RFID component having a defined surface area. The EAS component surface area is configured to at least partially overlap the RFID component surface area. The RFID component includes an antenna which at least partially overlaps the first surface. A substantially planar spacer having a thickness is at least partially disposed between the defined surface areas of the EAS and RFID components. The thickness of the spacer determines a read range between an RFID reader and the RFID component. The RFID reader is capable of activating the RFID component when the RFID component is within the read range. The antenna has a complex impedance, and the EAS component forms a part of an impedance matching network of the antenna.
