Abstract: A method and device for detecting an overhead cable from an aerial vessel, for instance from a helicopter in motion, and specifically for use in a landing preparing procedure. The method includes providing, from a camera arranged in the aerial vessel, a plurality of images of an area beneath the aerial vessel when the aerial vessel is in motion; detecting lines in the images; determining if the lines represent lines at ground level or lines at a level above ground level; and determining if a line at a level above ground level represents a possible overhead cable. The step of detecting lines in the images may include a modified SUSAN algorithm. The step of determining if the lines represent lines at ground level or lines above ground level may include parallax calculation.

Abstract: A cleaning device (10; 110; 210), in particular for cleaning hook-and-loop fasteners, includes a plurality of projections (16; 116; 216) which project inclined from a surface (13; 113; 213) of the cleaning device, such that between the projections and the surface (13; 113; 213) there is formed a mouth (17) respectively, the cross-section of which is tapering in an xz-plane from a mouth opening (B, D) in a sharp angled manner towards a vertex (C) wherein the mouth opening (B, D) includes an angle (?) in the xz-plane of 10 to 40° with the vertex (C) as center of the angle (?).
