Abstract: A method for detecting a cleaning need of a commercial cooking appliance with at least one cooking surface. The method includes the steps of capturing at least one image of at least a part of the cooking surface and/or at least a part of a cooking product, comparing the captured image of the part of the cooking surface with a prestored reference image of a contaminated cooking surface requiring cleaning and/or of the captured image of the part of the cooking product with a prestored reference image of the cooking product in a cooking status indicating a need for cleaning the cooking surface, and deciding, based on the result of the comparison, whether a cleaning is needed. A further aspect relates to a quality management monitoring system as well as a commercial appliance with a quality management monitoring system.

Abstract: A description is given of a modular laser processing system (10) for processing a workpiece (20) by means of a processing laser beam (14), which system has a multiplicity of functional modules (100) with a beam passage region (102) which can be connected to one another in series along a processing laser beam path, comprising a functional module (100) embodied as a fiber connection module (104) and serving for accommodating a fiber end from which the processing laser beam (14) emerges, and a functional module (100) embodied as a collimator module (106) and having a collimator lens (16a, 16b, 16c), which collimates the processing laser beam (14), wherein the collimator lens (16a, 16b, 16c) is selected from a group of collimator lenses having different focal lengths which correspond to a raster dimension (L1) or to an integer multiple thereof, characterized in that the length (A) of the beam passage region (102) of a functional module (100) along the processing laser beam path corresponds to the raster dimension

Abstract: A laser machining head for machining a workpiece by a laser beam having a housing which has an inlet opening and an outlet opening between which a passage is constructed for the laser beam through which is led a working beam pathway; focusing optics for focusing the laser beam into a working focus which is located outside the housing at a distance from the outlet opening; a sensor arrangement, and a beam deflecting device. In order to provide a laser beam machining head which, whilst having fixed and compact external dimensions, enables a simple adaptation of the sensors to the respective machining tasks, the sensor arrangement comprises a sensor module arranged in a side wall of the housing next to the laser beam through passage; and the radiation diverting device directs the radiation, coming from a zone of interaction determined by the working focus, onto sensors of the sensor arrangement so that at least one portion of the radiation can be detected for monitoring the machining of a workpiece.

Abstract: A bearing support for a headrest in a motor vehicle which is pivotal within certain limits after overcoming a constantly effective friction force; a bearing socket which is rigidly connected with the lower area of the headrest member has an essentially triangularly shaped cross section and receives a bearing bolt that is being pressed by a wall subject to an elastic prestress against the remaining walls of the bearing socket.
