Abstract: A device include a first camera, a second camera, and a shutter assembly. The shutter assembly includes a switch, a link coupled to the switch and having a first cover, and an arm coupled to the link and having a second cover. Actuating the switch to a first position disposes the first cover within a first field of view of the first camera and the second cover within a second field of view of the second camera. Actuating the switch to a second position disposes the first cover outside of the first field of view and the second cover outside of the second field of view.

Abstract: The invention relates to a reversing aid for supporting the driver of a motor vehicle, particularly when parking, comprising at least one transmitter (12), arranged at the rear end region (10) of the motor vehicle, for emitting measuring beams (14) into the rear danger zone, at least one receiver (16, 16a, 16b), arranged at the rear end region (10) of the motor vehicle, for receiving beams (20) reflected at at least one detected object (18), a distance-measuring device for determining the distance (A) between the vehicle and the detected object (18), and a display device (22) for optically representing the distance (A) from the detected object (18).

Abstract: In the disclosed apparatus, a reference image sensor continuously scans a lmed atlas of images representing terrain being overflown while a second sensor simultaneously scans the terrain. A correlator compares the signal and the reference image sensor describes a course, corresponding to that of the flying body, over the film, in response to control signals based upon the correlation results. The reference image sensor reads only the area of the film around the course.
