Abstract: A method and a device for generating images in a motor vehicle are provided. An infrared-sensitive camera generates images of the surroundings of the motor vehicle. An emission source emitting in the near infrared spectral region is used for the pulsed illumination of sub-ranges of the image recording region of the camera. The camera generates the images by recording partial image regions. To record the partial image regions, a synchronization in time is carried out with the pulsed illumination of the sub-range including at least the partial image region. In the preferred exemplary embodiment, the recording of partial image regions of an infrared-sensitive CMOS camera is synchronized in time with a laser diode array emitting in the near infrared spectral region.

Abstract: The invention relates to a starter device (1) for starting internal combustion engines, comprising an electromagnetic toe-in mechanism which is used to displace an axially displaceable pinion shaft (5), starter pinions (6) which are arranged in the front thereof, in addition to a start-stop mechanism which is embodied in such a manner that in a stop phase of the internal combustion engine, even when the internal combustion engine is stopped, said start-stop mechanism provokes a positioned state of the toe-in mechanism, such that during a subsequent starting of the internal combustion engine, the starter pinion (6) is already arranged in an advanced position, enabling power loss to be reduced. This is achieved by a maintaining mechanism (15) which maintains the electromagnetic toe-in mechanism in the advanced position and in a currentless manner during and/or after the stop phase.

Abstract: Brake installation consisting of a master cylinder associated with a brake booster furnished with a motor driving an actuator piston and acting on the primary piston of the master cylinder by means of a reaction disk against which the piston rests. For a safety operation, the hydraulic actuator connected to the control rod actuated by the brake pedal rests on the rear face of the reaction disk. The actuator piston is combined with an auxiliary piston in order to interact with the reaction disk and it is guided by its sleeve-shaped portion in a bore of the body of the brake booster.
