  • Control for embedded and door-mounted antennas
    Patent number: 7609160
    Abstract: A system 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.

  • Radio frequency ID Doppler motion detector
    Patent number: 7609163
    Abstract: A system and method for a radio frequency identification (RFID) reader for use in an RFID detection system. The reader has an RF source for generating RF signals. An antenna is coupled to the RF source. The antenna transmits interrogation RF signals to one or more RFID markers within an interrogation zone and receives communication signals from one or more items within the interrogation zone. The communication signals include Doppler signals indicating movement of an item within the interrogation zone. A receiver receives the communication signals and motion detection circuitry detects the Doppler signals.

  • System and method for communicating data in a video system
    Patent number: 7573500
    Abstract: A system and method of controlling a video camera arranged to provide a video signal on a transmission medium including: transmitting command data on the video transmission medium to the camera, and receiving response data from the camera over the video transmission medium during a single vertical blanking period of the video signal, improving controllability of dome type cameras. Using an encoding format with data with bit widths narrower than those conventionally used in UTC protocols, increases the usable transmission medium length for the system by allowing for longer propagation delays without errors caused by interference. A method of downloading data to a camera by disabling the video signal, and a method of self-instantiating camera functions are also provided.
