摘要： A method for operating a capacitive touch-sensitive switch having a capacitive sensor element and a sensor circuit includes initially setting a scanning frequency of the capacitive touch-sensitive switch with a good signal-to-noise ratio and then operating the capacitive touch-sensitive switch at a scanning frequency which has been set to detect switch actuation. The process of setting the scanning frequency includes operating the touch-sensitive switch using a first measurement method and at a selected scanning frequency, detecting the measurement signals from the sensor circuit and checking whether the detected measurement signals contain or could contain a critical alias effect. If no critical alias effect and no possibility of a critical alias effect are detected during the check, the scanning frequency can be set as the selection frequency for detection operation of the touch-sensitive switch. A capacitive touch-sensitive switch is also provided.

摘要： A method and a device for detecting a boiling state of a liquid and a domestic cooking appliance permit a boiling state of a liquid to be detected during a process of heating the liquid in a heating zone, for example of an induction cooktop. A sensor senses vibrations that are caused during the heating of the liquid in the form of a measuring signal. An evaluation unit converts a time diagram of the sensed measuring signal into a frequency spectrum and then determines the boiling state of the liquid by using an intelligent algorithm on the basis of the frequency spectrum.

摘要： An operator control device has a control panel with a user side facing a user and an inner side facing away from the user. The control panel has an operator control element region. A rotary knob is positioned on the user side of the control panel in the region of the operator control element region and can be rotated about a rotational axis. The rotary knob is detachably attached to the control panel and has an encoder block with a code section which is at a distance, changing along the circumferential direction, from a lower end side, facing the control panel, of the rotary knob. An optical sensor is arranged on the inner side of the control panel in the region of the operator control element region and is configured to sense a distance between the optical sensor and the code section of the encoder block by electromagnetic radiation.

摘要： A circuit configuration detects zero-crossings and/or a brownout condition. The circuit configuration contains a zero-crossing detection circuit, a brownout detection circuit, an isolation and digitization circuit connected to the zero-crossing detection circuit and the brownout detection circuit, and a filtering circuit connected to the isolation and digitization circuit. The single circuit configuration can be used for detecting zero-crossings of single-phase and multi-phase systems as well as ascertaining a brownout condition of either the single-phase or the multi-phase systems.

摘要： A rotary knob operator control apparatus for an electrical domestic appliance has a mounting board on a side of an operator control panel facing away from a user, a first electrode configuration on the mounting board and a substantially annular operator control element on a side of the operator control panel facing toward the user. The operator control element has a second electrode configuration and a holding device for the operator control element on the operator control panel. The operator control element rotates about an axis perpendicular to the operator control panel. The operator control element is latched relative to the operator control panel in predefined rotary positions by a latching device, so the second electrode configuration on the operator control element is oriented in a predefined manner relative to the first electrode configuration. An electrical domestic appliance having at least one rotary knob operator control apparatus is also provided.

摘要： An actuating element for an electronic domestic appliance has an electrically non-conductive carrier which defines at least one preferably substantially cylindrical detection portion. A plurality of electrically conductive measuring electrodes is spaced apart from one another along the detection portion of the carrier. A preferably substantially annular operating element is disposed at a first predefined distance from the measuring electrodes and is movable relative thereto. The operating element additionally has at least one sensor portion which is at least partially electrically conductive and is disposed at a second predefined distance from the measuring electrodes. The second predefined distance is different from the first predefined distance, so that a movement of the sensor portion and therefore of the operating element relative to the configuration of measuring electrodes can be detected.
