Abstract: A cooking appliance includes a cooking compartment having a loading opening and a cooking compartment door for closing off the loading opening, with the cooking compartment door including a viewing window. A camera is directed into the cooking compartment for recording an image in the cooking compartment. Coupled to the camera is an image processing facility which is configured to anonymize an image region in the image recorded by the camera.

Abstract: A method for calibrating an oxygen sensor of a household appliance includes a calibration process which is automatically started when at least one status parameter of the household appliance has at least reached a predetermined threshold value. The household appliance can be a steam cooking appliance, and the oxygen sensor can be a lambda probe.

Abstract: A household appliance includes a treatment chamber closable by a door for treatment of items to be treated by a plurality of treatment processes, and a proximity detector designed to identify a presence of a person approaching the household appliance. The household appliance is designed to carry out an action in dependence on a state of a treatment process in progress, when identifying an approach of the person.

Abstract: A cooking appliance includes a cooking chamber for cooking a product to be cooked. An air-guiding plate is arranged in the cooking chamber and coupled by a coupling device to a transmitter/receiver unit which transmits and/or receives a high frequency signal. The air-guiding plate is configured as a planar antenna for transmitting the high frequency signal between the coupling device and a sensor that can be arranged in the cooking chamber.

Abstract: The invention relates to a method and a circuit arrangement for preventing overheating of a cooking appliance. The arrangement includes a power circuit with a heating element and a control circuit with a coupling switch. The control circuit and the power circuit are coupled by the coupling switch. The arrangement further includes a safety switch to the control circuit. The coupling switch interrupts a power supply to the power circuit to the heating element when a limiting temperature in the cooking appliance is exceeded.

Abstract: A roller tool is used within a sheet deformation facility for the linear deformation of sheet metal. The roller tool comprises a press roller having a shaft and a roller body rolling around the same as well as a counterbody. The press roller and the counterbody can be jointly moved in a linear manner relative to a sheet positioned between them that is to be processed for performing the sheet metal deformation. The roller body has a plurality of roller discs which are adjacent to each other, which together form the section of the roller body that can be placed onto the sheet to be processed and which can rotate around the shaft independently of each other. The sheet deformation facility is furthermore provided with a roller tool support and a drive for pivoting the roller tool support around an axis perpendicular to the sheet that is to be processed.

Abstract: A heater comprises a casing, which has an interior chamber. It further comprises a rotor, which is formed as an impeller on the one hand and as an eddy-current disk on the other, and a magnet support, which is equipped with permanent magnets and disposed non-rotarily in the casing and which is displaceable into an operating position in the direct neighborhood of the eddy-current disk and into a position of rest spaced therefrom. The eddy-current disk and the magnet support equipped with permanent magnets are rinsed by water.

Abstract: In a method for electrically contacting thin-film solar modules interconnected in integrated fashion, a number of solar cells forming a module are created by structuring a layer on a substrate to produce strip-shaped, side-by-side solar cells, and electrically conductive contact strips are laid over the electrode layers of the two outermost, individual solar cells. The conductive strips are held in place by a lamination using hot-melt adhesive foil at elevated pressure and temperature, in the same step wherein a backing is laminated with the solar module. If necessary, the contact strips can be attached by an electrically conductive paste or utilizing an ultrasonic welding process.
