Abstract: A door system includes a sensor device for monitoring a vertical door edge. The sensor device has a transmitter that generates a light beam that runs along the vertical door edge, and a receiver to receive the light emitted by the transmitter. Further, an element of the sensor device is mounted in a region of a base of the door, with the sensor element being either in or on the base in front of the vertical door edge.

Abstract: A safety system for safeguarding a moving, guided motion element against unwanted collisions with an object located on a motion path in the direction of motion of the motion element. The safety system includes an object-detection device for detecting an object in an area of the motion element. The object-detection device can be blocked with respect to object detection by a motion of the motion element, and has an electronic unit with which the motion of the motion element can be controlled and which is configured to assign a blocked state to the object-detection device when the motion element approaches in the blocked state an object or motion element will not trigger a safety mode and when a shut-off signal coming from the motion element is detected, at least part of the object-detection device is transferred into the blocked state.

Abstract: A safety system for safeguarding a moving, guided motion element against unwanted collisions with an object located on a motion path in the direction of motion of the motion element is proposed, which safety system comprises an object-detection device for detecting an object in an area of the motion element. The object-detection device can be blocked with respect to object detection by a motion of the motion element, and has an electronic unit with which the motion of the motion element can be controlled and which is configured to assign a blocked state to the object-detection device when the motion element approaches, in which blocked state an object or motion element does not trigger a safety mode, wherein shut-off mechanism are provided which, when a shut-off signal coming from the motion element is detected, transfer at least part of the object-detection device into the blocked state.

Abstract: A system for detecting an object in a monitoring area with a plurality of sensors, each including a transmitter and a receiver, and an electronics unit for evaluating the receivers. The electronics unit is capable of assigning a contact address to a transmitter and/or to a receiver, wherein address assignment is effected such that after the address assignment it is possible for the electronics unit to associate receivers with transmitters.
