摘要:
A display device for a motor vehicle is proposed, which is used to display a virtual image on the windshield of a motor vehicle. The image is displayed by way of an image-forming unit which is arranged in an upper area of the windshield or in a region of the vehicle roof. The generated image is guided via a first aspherical mirror and a second aspherical mirror onto the windshield.

A camera system for a motor vehicle includes an image sensor for outputting image signals and multiple optical elements. The optical elements include a switchable optical element which is part of a first camera optical system in the first switching state and part of a second camera optical system in a second switching state. Optical elements form the first camera optical system for detecting a first surrounding and for imaging the first surrounding on the image sensor with the aid of a first object distance, and optical elements form the second camera optical system for detecting a second surrounding and for imaging the second surrounding on the image sensor with the aid of a second object distance which differs from the first object distance.
摘要:
In a circuit for operating a fluorescent lamp with controllable luminance, with the fluorescent lamp comprising a discharge path and heater coils, the discharge path is connected through a transformer to a controllable alternating current source. The current through the heater coils is preferably controllable in such fashion that the sum of the current through the discharge path and through the heater coils remains essentially constant.

A micromechanical component is described having a component which has a moth-eye structure which covers at least a partial surface of the component. At least a portion of the partial surface, as a first contact surface, may contact a contact component of the micromechanical component on at least one second contact area of the contact component, which has a needle-shaped microstructure, the moth-eye structure of the first contact area and the needle-shaped microstructure of the second contact area being at least partially interlocked with one another. Alternatively or additionally, at least a portion of the partial surface may be at least one partial area of an outer side and/or of an exposed inner side, facing the inner space, of the component configured as a light window. Also described is an optical device having such a micromechanical component, a manufacturing method for a micromechanical component, and a manufacturing method for an optical device.
