Abstract: A sensor comprises a housing comprising a window that extends over angular detection range and scanning-light passes therethrough, a scanning unit inside housing to scan angular detection range by emitting and receiving scanning-light with a rotating mirror to deflect scanning-light. A window monitoring unit detects pollution on window comprising at least a first and second opto-electronic components to establish a test-light path therebetween and attached to housing. The test-light path passes through the window. The window monitoring unit comprises an optical component to redirect the test-light, the opto-electronic components and optical component are arranged where a plurality of test-light paths are generated along angular detection range.

Abstract: An optical sensor (10) is disclosed. It may comprise a scanning unit (14), a transparent window (20) with a lateral extension (WE) and a height extension (HE) through which a scanning-light can pass, and a window monitoring unit (50) to monitor the transparency of the window (20). The transparent window (20) has at least one inclined window element (52, 56) that has an external element surface (54, 58). The window monitoring unit (50) includes a test-light emitter unit (30) that emits test-light at a plurality of separate emitting positions (EP.X) along the lateral extension (WE), a test-light receiver unit (40) that receives a test-light along a plurality of separate receiving positions (RP.Y) along the width extension (WE), and a determination unit (100) to determine the change of transparency of the window (20) in such way that the test light transmitted along a plurality of light paths (P.X.Y) is analyzed.

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.
