Abstract: An automatic door can include a plurality of millimeter wave (mmW) sensors that are each configured to sense a door area. Each mmW sensor includes a mmW radar configured to capture mmW radar data and an inertial measurement unit (IMU) configured to measure an orientation of the mmW radar. Based on IMU data from the mmW sensors, the mmW radar data from the sensors can be combined so that the door areas can form a combined door area. Multiple targets can be detected and tracked through the combined door area at high resolutions and in a variety of environmental conditions. Control of the automatic door can be enhanced in a variety of ways by classifying the targets and predicting their movements in the combined door area. Further, the classification and prediction of targets can facilitate safe and reliable operation by filtering operation based on certain targets and/or motions.

Abstract: A test device for testing automatic door systems has a test circuit including a display, a micro-controller, a memory for storing data and a test program, and a control switch for controlling operation of the test program by the micro-controller. The test device is installed by interposing the test circuit between the controller and sensors of the automatic door system. A selector switch on the test device is moveable between first and second positions. When the selector switch is in the first position, it completes a data path between the test circuit and the controller and blocks the exchange of data between the sensors and the test circuit and the first connector. When the selector switch is in the second position, it completes a data path between the test circuit and the second connector and blocks the exchange of data between the controller and the test circuit and the second connector.

Abstract: A sliding door system employs an electric power link. The electric link includes a ribbon conductor which is enclosed in a protective chain-like guard to provide electrical communication between the sliding door and the door header. Electrical modules such as electromagnetic locks, switches and sensors are mounted directly on the sliding door. Safety sensors are mounted at the leading and trailing edges of the sliding door panels to sense whether an obstacle or traffic has cleared.

Abstract: A threshold safety sensor for a sliding door system employs infrared transmitters and a photo diode for detecting traffic at or near the threshold of a sliding door system. The transmitters are pulsed in a time spaced sequence. An input signal derived from the operate initiating signal of the automatic door operator is employed for enabling a latch. The latch sets a relay to a state for maintaining the doors in an open position when traffic is detected in the sensor detection zone.

Abstract: An automatic door installation with two traffic sensors mounted on each side of the door adjacent the opposite side edges thereof, each having a reflected energy receiver and a plurality of radiant energy emitters with angularly spaced beam axes to provide broad coverage areas intersecting the traffic path of travel. The emitters of each sensor are selectively activated at different radiant energy levels and/or selectively deactivated to vary the affective coverage area as the door is swung between its closed and open positions.

Abstract: An automatic door installation with four traffic sensors mounted on the door jambs on opposite sides of the doorway opening and having radiant energy emitters and reflected energy receivers for sensing doorway traffic. Two sensors are employed to cover the exit or swing side of the doorway, a threshold sensor is employed to cover the threshold area and an entrance sensor is employed to cover the entrance side of the doorway. The entrance and two exit sensors each have a plurality of radiant energy emitters with angularly spaced beam axes to provide broad coverage areas intersecting the traffic path of travel. The emitters of the exit and threshold sensors are selectively deactivated as the door is swung between its open and closed positions to avoid sensing the door. The emitters of all four sensors are pulsed in a predetermined sequence and the sensor receivers are timely activated to receive reflected radiant energy from the respective emitter(s) only.
