Abstract: A method for operates an operator control device for a motor vehicle. The operator control device has a rotary actuator which is rotatably mounted on a holding element, and a coding element, by detecting a first actual sensor value using coding of the coding element in the current rotational position of the rotary actuator. The method involves determining a current rotational angle between the rotary actuator and the holding element on the basis of the detected first actual sensor value, respectively providing at least one setpoint sensor value at predetermined rotational angles between the rotary actuator and the holding element, assigning the detected first actual sensor value to one of the at least one setpoint sensor valves, and adapting the first actual sensor value to the setpoint sensor value, assigned thereto, for the determination of the current rotational angle.

Abstract: A method for calibrating an optoelectronic component having a light emitter/receiver unit and a connection unit includes the steps of setting an initial relative position of a first part and a second part of the connection unit. After that, the first part is displaced in a reference plane relative to the light emitter/receiver unit. Next, the first part is affixed to the light emitter/receiver unit. Then the second part is displaced relative to the first part and is also affixed to the light emitter/receiver unit. An optoelectronic component is also provided.

Abstract: The electro-optical device has a housing and an electro-optical composite component. The composite component has an electro-optical basic component, in particular a photodiode, a laser diode, or an LED, into which light can be injected and/or from which light can be emitted. In order to be able to manufacture the housing for the electro-optical basic component in the most cost-effective way possible, there is provided a guide sleeve for the electro-optical composite component. The guide sleeve is connected to the basic component and it guides a plug with a ferrule of an optical waveguide. When the ferrule is plugged into the guide sleeve, the optical waveguide is optically coupled to the basic component.

Abstract: A transmission and reception module for a bidirectional optical communication and signal transmission includes a light transmitter having a first lens coupling optical element, and a light receiver. A fiber connection has a second lens coupling optical element for a common optical waveguide. A beam splitter is disposed in a free beam path. A common housing surrounds the foregoing. The light transmitter, the beam splitter and the fiber connection as well as the light receiver which is orthogonal thereto, are disposed axially symmetrically.
