    Abstract: The combination of a pusher dispenser having a coil spring resiliently urging a plate towards a front of the dispenser, a track for guiding the plate, a bottom surface along the track, and an electrically non-conductive insert supported by the bottom surface and having a length, a plurality of RFID tags attached to the insert along its length, the insert supporting the RFID tags at a level adjacent and below an extension of the coil spring whereby an extension of the coil spring is effective to shield the RFID tags from a reader.

    IPC: G06K7/10

    CPC classification number: G06K7/10366

    Abstract: A system for detecting the direction of movement of an RFID tag along a path comprising two RFID portals, each of said portals being arranged to detect an RFID tag in a respective zone along the path, the zones being arranged to be effectively exclusive of one another, a RFID tag reader having an associated processor and multiple separate ports, each port being connected to one or the other of the portals, the processor being arranged to determine which portal first receives a RFID tag signal or signals and which portal subsequently receives a second signal from the same tag or tags detected by the first signal receiving portal, the processor providing a signal corresponding to a direction of movement, along the path from the first signal receiving portal to the second signal receiving portal.

    IPC: G06K7/10

    CPC classification number: G06K7/10396

    Abstract: A portable RFID tag reading system to be carried by an operator and including a reader with associated processing, the processing being programmed to record as a set the identity of all of the RFID tags in the range of the reader when the reader finds a specific RFID tag and to detect movement of the operator after the specific RFID tag is found by recognizing a change in RFID tags seen by the reader from the recorded set.

    Abstract: An RFID antenna having two flexible elongated conductive transmission lines with coplanar RFID energy radiation perturbations distributed along the transmission lines, the transmission lines and perturbations being folded between ends of the transmission lines so that the transmission lines of one fold overlie and are adjacent the transmission lines of the other fold and an electrically insulating layer disposed between lengths of the transmission lines on either side of the fold.
