Abstract: The invention relates to an automatic swing door (10, 100), comprising a door controller (22, 122), 10 further comprising a door leaf arrangement (12, 112) that is pivotably attached to a door frame (30), where the door leaf arrangement (12, 112), comprises a door leaf (14, 114) that has a following face (15b) that is facing to the door opening (20) and a leading face (15a) that is facing away from the door opening (20), a hinged edge (15d) and a main closing edge (15c) that lies opposite to the hinged edge (15d), the door leaf arrangement (12) comprises a leading face sensor (16) that is attached to the 15 leading face (15a) of the door leaf (14), where the leading face sensor (16) provides a scanning field that at least covers a zone that lies next to the leading face of the door leaf.

Abstract: 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.
