Abstract: In a process for assisting a user of a motor vehicle in operating components of the motor vehicle, operating conditions of the components are switched by actuating of operating elements. An assistance request element is also provided. Operation of the assistance request element causes a subsequent operation of an operating element only to display information concerning the operating condition which can be switched (in the normal operation) by means of this operating element.

Abstract: Movement monitors with segmented collecting optics have dead zones between the individual focusing segments, in which a radiating object can stay without tripping a signal. These dead zones are to be practically avoided with the movement monitor according to the invention. To this end, deflecting optics after the collecting optics in each case deflect a portion of the bundle of rays incident parallel to the principal ray of a segment in such a way that at least two radiation maxima occur. Given a corresponding change in position of a radiating object, these radiation maxima strike sensor elements of the sensor one after another. In this way, dead zones are reduced to such an extent that they are practically eliminated. The movement monitor serves for zonal monitoring inside and outside buildings. By transmitting a signal, it can switch on lighting or trip an alarm.
