Abstract: In a method for the detection of blemishes on the surface of an object, e.g. for the detection of blemishes in the paintwork on the surface of a motor vehicle body, a strip of light is produced on the surface by means of a lighting system, and this strip of light is moved over the surface by relative movement between the lighting system and the surface; strip-like sections of the surface of the object are in each case recorded stepwise in the region of the strip of light, the step size of successive recordings being smaller than the width of the strip of light. In an apparatus for carrying out this method, the lighting system comprises at least one lighting unit with a light exit window, and the recording system comprises at least one sensor unit with a light entry window, the light exit window and the light entry window being arranged closely adjacent.

Abstract: In a method and a device for reliably detecting at least the beginning of a voice command for a voice control of function elements, signals of a first microphone to which contact sound of an operating person is applied, are used for triggering a second microphone which is directed towards the mouth of the operating person in order to improve the reliability of the voice control in high ambient noise.
