Abstract: In a method for automatically handling objects, the objects are held by means of an object gripper or the like and are subjected to a handling process, a transport process, or an assembly process in the held state. The position of at least one surface section of the held object relative to a contact surface of the object gripper or the like is monitored by means of at least one position sensor arranged at the object gripper or the like; and a warning signal or control signal is generated in the event of a change of the position during the handling process, the transport process, or the assembly process.

Abstract: A method for the detection of an object includes transmitting light in the direction of a reflector by a transmitter. The transmitted light is reflected by the reflector and is imaged as a reflector image and is detected by the receiver. The reflector image is evaluated and an object detection signal is generated if an at least partial interruption of the transmitted light is recognized. A light object incident onto the receiver outside the detection region is detected by the receiver, is examined for predetermined object properties and is classified as a reflector image or as an interfering light object based on the object properties. In the case of a classification as an interfering light object, a movement of the interfering light object on the receiver is determined and the generation of the object detection signal is executed based on the determined movement of the interfering light object.

Abstract: The invention relates to a method of operating an opto-electronic sensor, in particular a light barrier, in which a light signal is transmitted by means of a light transmitter into a monitored region and a light receiver designed to receive transmitted and reflected light signals delivers a signal, the amplitude of which is investigated for the presence of an object in the monitored region, wherein an object detection signal is transmitted when an amplitude threshold value is exceeded or fallen short of, wherein, before taking the sensor into operation, the threshold is automatically set in dependence on amplitude values which occur in a predetermined measurement time interval in the context of an initialization process with an object-free monitored region, and is thereby adapted to the operating conditions which exist during the initialization process, or wherein the threshold value is automatically adjusted during the sensor operation in dependence on amplitude values which have occurred in a specific measu

Abstract: A method for operating an optical light sensor for the detection of objects present in the monitored region in which light signals are transmitted into the monitored region in specific time intervals. The transmitted light signals and also the interference signals which occur are received and are evaluated for the detection of objects present in the monitored region, with the transmission reception of the light signals, and also the reception of the interference signals, respectively taking place in time sequential frame intervals. In the absence of an interference signal within a frame interval the transmission of the light signal takes place at the end of the frame interval defining a normed transmission timepoint for the respective light signal. On the occurrence of an interference signal within a frame interval the transmission of the next light signal is delayed timewise relative to its normed transmission timepoint. Furthermore a light sensor of this kind is described.
