Abstract: A method and device determine the change in pitch angle of a camera of a vehicle. At least three images, each reproducing a detection area in front of the vehicle, are sequentially recorded and corresponding image data are generated. A position of a first reproduction of a stationary object in the first image is determined as a first image position. A position of a second reproduction of the stationary object in the second image is determined as a second image position. On the basis of at least the first image position and the second image position, the course of a straight line is determined. A position of a third reproduction of the stationary object in the third image is determined as a third image position. On the basis of the distance between the third image position and the straight line, the change in the pitch angle is determined.

Abstract: A mine extractor for removing buried mines having a plurality of leaf springs disposed in parallel side by side relationship and mounted on a common support. The extractor further comprises adjacent auxiliary springs and thereby forming additional batteries, a slide attached to the springs and adapted to slide on its bottom on the ground and/or an apparatus for swinging a beam and the slide with respect to a base to lift the slide from the ground.
