Laser scanner monitors region in front of an opening. Monitoring region is delimited by a frame, in front of which an edge region is located. Propagation time sensing means determines position of an object in the monitoring region by a propagation time measurement of laser pulse, an evaluation unit being provided, by means of which first object information is produced, whether an object was sensed by the propagation time measurement. An intensity sensing means evaluating received laser pulse with respect to the intensity thereof and the sensed intensity is compared with a reference intensity stored in a memory unit. Second object information being provided in the event of deviation beyond a certain threshold value, whether an object is located in the hazard edge region on the basis of the intensity deviation. A safety signal generated by the evaluation unit if first or second object information is positive.

A movable wall panel system is disclosed. The movable wall panel system may include at least one monitoring system to monitor at least one area adjacent the movable wall panel system. The movable wall panel system may include a touch screen as part of an operator interface.

A safety curtain and system includes multiple light emitters and multiple light receivers to detect traffic approaching a doorway. The safety curtain my include pairs of multiple light emitters and receivers positioned on both sides of a passageway (doorway) so as to detect approaching traffic. The multiple light emitters and light receivers may detect a height of an approaching traffic (e.g., person or vehicle) and initiate warning lights of a possible door closing. The detected approach of traffic may cause the door to be stopped, reversed or slow down. The system may include a computer to monitor the signals from the receivers and may control the motion of the door.

An automated door-opening device is disclosed that includes a first sensor disposed on the outside of the door. The first sensor is adapted to recognize a predetermined pattern of a gesture made by a patron. The gesture made in front of the first sensor opens the door by a first actuator. A second actuator can be used to lock or unlock the door, thereby providing full hand-free operation of the door. A hinge system is disclosed that includes three off-set hinges adapted to utilize the weight of the door to cause the door to self position and allow manual operation of the door.

There is disclosed an automatic door installation 10 comprising: a door opening 16; and an optical door sensor comprising: a plurality of transmitters 30 arranged in a transmitter array 22, each transmitter 30 being configured to transmit an optical beam across the door opening along a respective beam path; a plurality of receivers 32 arranged in a receiver array 24, each receiver 32 being configured to generate a receiver output signal based on an intensity of light received. The plurality of receivers 32 are arranged in at least one set of receivers, the receivers of the or each set being linked so that the respective sensor output signals are combined into a compound signal for the respective set.
