Abstract: A projection apparatus for producing a pixel-based illumination pattern has a laser light source for producing coherent laser light and a micromirror array with a multiplicity of mirrors. The mirrors are implemented so as to be controllable in terms of their position, for setting a brightness and/or color of a respective pixel of the pixel-based illumination pattern. The laser light source emits the laser light towards the micromirror array. A beam-shaping element splits the laser light from the laser light source into a multiplicity of partial beams and each of the partial beams is oriented toward one of the mirrors of the micromirror array.

Abstract: A filter device (10) for filtering high-frequency interferences, such as due to switching flanks of a DC converter, has a current path (4) between an input (2) and an output (3), and an inductor (L) in the current path (4), wherein the inductor (L) is disposed in the current path (4) as a first component and is connected to the input (2), and wherein a reverse polarity protective diode (D) is disposed in series with the inductor (L) downstream thereto.

Abstract: A method is provided for increasing the robustness of a vehicle headlight comprising a cylindrical prism that can rotate about a rotary axis in a plurality of rotary positions and comprising a Hall effect sensor by means of the output signals of which the rotary position of the cylindrical prism can be determined. According to the method, a check is made as to whether a defect of the Hall effect sensor is present. In the event of a defect of the Hall effect sensor, a stop is temporarily provided and the rotary position of the prism is verified by being blocked at the provided stop.

Abstract: To detect an entrapment situation when a driven component is adjusted using a mechanical adjustment system which has an electric motor (2), a value (Fakt) relating to the force acting upon the driven component is compared with a threshold value (FTh) relating to a reference value (FRef). The reference value (FRef), and thus the threshold value (FTh), are continuously matched, for the purpose of force tracking, with the force value which changes during the movement of adjustment depending on the mechanical system.

Abstract: A device for reducing booming noise in a motor vehicle has a wind deflector (3) having openings. The device furthermore has an air source (1), which is arranged in the motor vehicle and connected to the wind deflector. The air provided by the air source can be channeled to the wind deflector and released through the openings (4) thereof.

Abstract: In a method and a device for pulse width modulated (PWM-) activation of an electrical drive motor (2) of an adjustment arrangement based on a reference of the mechanical system of the adjustment arrangement that corresponds to a relationship between the force (F) on the drive motor (2) and the adjustment path (s) or the adjustment time (t) of the adjustment arrangement stored in a memory (9), an anticipated future force value (F(t+t0)) is determined based on the reference of the mechanical system in order to adjust the PWM activation in advance by utilizing this future force value such that motor synchronization fluctuations can be prevented upon anticipated mechanical fluctuations in the adjustment arrangement.

Abstract: In a method and a device for detecting the light power emitted by an LED light source, the LED light source is driven with a drive signal corresponding to a binary code.
