Abstract: A sensor device having a sensor arrangement for detecting moving objects that includes a sensor and an electronic unit. The sensor arrangement is designed to detect an object and to subsequently investigate whether there are present within the surface of the object regions that move at a different speed and/or acceleration. The sensor arrangement can also investigate whether the object is accelerating.

Abstract: Systems and methods are provided for defining a safety zone in an industrial automation environment. The method includes monitoring an object that approaches an operating zone where equipment is controlled within the operating zone. This includes determining the speed or direction that the object approaches the operating zone. The method includes dynamically adjusting a safety region in view of the determined speed or direction of the object and enabling or disabling the equipment within the operating zone based in part on the object entering the safety region.

Abstract: A time of flight, TOF, camera unit for an optical surveillance system and an optical surveillance system comprising such a TOF camera is disclosed. The TOF camera unit comprises a radiation emitting unit for illuminating a surveillance area defined by a first plane, a radiation detecting unit for receiving radiation reflected from said surveillance area and for generating a three-dimensional image from said detected radiation, and at least one mirror for at least partly deflecting said emitted radiation into at least one second plane extending across to said first plane and for deflecting the radiation reflected from said second plane to the radiation detecting unit. The TOF camera and the at least one mirror may be ar-ranged on a common carrier element.

Abstract: A safety switch device for switching a power supply for a load on and off, having at least one driveable switching element, in particular a relay, and a safety circuit for checking a switching state of the switching element. The switching element is in the form of a changeover switch in such a manner that a first contact is electrically connected to either a second contact or a third contact by means of a switching operation. A method for operating a safety switch device is also provided.
