    Abstract: An electronic article surveillance system responsive to the distance to a target within an interrogation zone is provided. The interrogation zone is defined by an electromagnetic field generated with a known level and transmitted by at least one antenna. A target within the interrogation zone can be any object, such as a person or shopping cart, within the interrogation zone. The target may include an EAS marker securable to an article for passage through the interrogation zone. The EAS marker is detectable at a frequency when in the electromagnetic field, and is detected by EAS detection equipment, as known in the art. The target within the interrogation zone is detected, and the distance from the antenna to the target is measured. The level of the electromagnetic field is controlled according to the distance to the target within the interrogation zone. The output level is adjusted according to the distance to the target. The EAS system can include multiple antennas each producing an electromagnetic field that in combination define the interrogation zone. A ranging transducer is mounted near each antenna, or at opposing ends of the interrogation zone to measure the distance to a target within the interrogation zone. The output level of each electromagnetic field transmitted by each antenna can be individually controlled according to the distance from that antenna to the target. Multiple targets can be detected, and the power level of each electromagnetic field is adjusted accordingly. The electromagnetic field can be switched off and on by detection of the target in the interrogation zone. The direction of motion of the target can also be detected and used as a factor in alarm activation decisions.

    Abstract: Cameras 31, 32 take images of an image space around a door. A distance calculation unit 33 calculates the distance to an object in the taken images. A coordinate transformation unit 34 detects the three-dimensional position of the object in the image space. The image space covered by the cameras 31, 32 is divided into a plurality of voxels. Some of these voxels are optionally set as constituents of the detection area. A judgement unit 36 judges whether the detected three-dimensional position of the object locates within or outside the detection area. If the object is present within the detection area, an output unit 37 produces an object detection signal, so that the door is allowed to open.

    Abstract: An anti-theft vehicle system for a vehicle wheel having a rotational axis includes at least one inhibitor disposed within the vehicle wheel to selectively engage and disengage the vehicle wheel to resist and allow rotational movement of the vehicle wheel about its rotational axis. The anti-theft vehicle system also includes rotatable structure disposed within the vehicle wheel and cooperating with the at least one inhibitor for moving the at least one inhibitor between an engaged position and a disengaged position with respect to the vehicle wheel. The anti-theft vehicle system further includes a receiver operatively associated with the vehicle wheel to receive a predetermined signal to activate the rotatable structure to move the at least one inhibitor between the engaged position and disengaged position.
