Abstract: A method of detecting the improper mounting of a sensor on a motor vehicle includes monitoring the output signals of the sensor, determining the noise levels in the output signals, and comparing the noise levels from the output signals to a threshold noise value to determine if the sensor is properly mounted. Preferably, the method monitors the output signals of a first sensor and a second sensor, determines the noise levels in the output signals being emitted by each of the sensors, and compares the noise levels of the first sensor to the noise levels of the second sensor to determine if the sensors are properly mounted.

Abstract: The headlight, especially for a motor vehicle, includes at least two separately adjustable reflectors and a reflector height adjusting mechanism for adjusting the reflector heights separately or synchronously. The reflectors include a first reflector for high beam light and/or fog light and a second reflector associated with a low beam light module. The reflector height adjusting device includes separate adjusting devices for individually adjusting the respective heights for the at least two separately adjustable reflectors and a coupling member for the separate adjusting devices. When the separate adjusting devices are put in a coupled state by the coupling member the heights of the at least two reflectors are synchronously adjusted by operation of only one of the separate coupling devices. The method for adjusting light radiated from the headlight includes performing a pre-adjustment in which each of the reflectors is separately adjusted by the separate adjusting devices.

Abstract: For the display of images, notably X-ray images, the complete image of full resolution, usually consisting of a group of images, may be substantially larger than the size that can be reproduced on a display screen. In accordance with the invention, the overall group of images is displayed on the display screen as an auxiliary image in a strongly reduced scale, the size of the auxiliary image being dependent on the group of images. Via a frame which is reproduced in the auxiliary image and whose dimensions and position can be varied, a part of the group of images, i.e. one image or separate neighboring images, is selected and displayed on the overall display screen. When the frame is shifted in the auxiliary image, the part of the overall group of images which is displayed on the display screen is also automatically shifted.

To provide a process and a device for implementing the process permitting the driver to change the actual speed of the vehicle to a different desired value in the most uncomplicated and reliable manner, the predetermined value P.sub.v (t) and/or M.sub.

Abstract: A passenger automobile or truck contains a unit which is formed by an internal combustion engine and a generator and which powers electric motors coupled with driving wheels of the vehicle via an energy distributor in the form of power electronics. An accumulator which can likewise be coupled with the electric motors via the energy distributor is provided as an additional power source. An electronic control unit receives driving signals from an accelerator pedal, in particular a position signal and a speed signal. The position signal of the throttle is interpreted as a request for a determined permanent output to be supplied by the internal combustion engine.The internal combustion engine is revved up to a new operating point in an "optimal" manner (e.g. with favorable fuel consumption), for example when a higher output is requested, while the generator is entirely or partially uncoupled from the load. Energy for accelerating the vehicle is provided in the meantime by the accumulator.
