Abstract: Displaying a graphics such as for example a diagram or a map on a display unit of a portable device requires a reduction in the number of pixels. In each case this requires a decomposition of the graphic into a number of blocks. To do this each block is usually subjected to what is known as “subsampling°. In such cases the semantically important contours disappear at least partly so that the content of the graphic is lost. To resolve this problem to a method is proposed which for a specific application assigns a weighting to the colors underlying the contours. For the reduction in dominant color is determined depending on the result of the weighting and this is simulated in a further procedural step from a set of specified basic and pseudo colors. In this way the semantically important contours of a graphic and thereby the readability are retained despite the fact that reduction has been undertaken.

Abstract: The present invention relates to an apparatus for stacking articles. The articles may comprise mail pieces. The apparatus comprises a base having a top surface. The top surface defines a rake element having extending fingers defining open spaces therebetween. A receiving unit is mounted proximate to the rake. The unit may be made to rotate. The unit further comprises a plurality of coils. The coils may be helical, concentric and vertically displaced so as to define a vertical open space therebetween. When rotating, the coils may be made to move in the direction of a support positioned atop the top surface. The support may further comprise a spring bias to urge the support against a stack of articles. A supporting wall is also provided as well as a supply element which directs incoming articles into the vertical opening. The movement of the coils transports the articles to a stack which is support on one side by the support, on another by the supporting wall and on yet another by the top surface.

Abstract: For a rotary switch (7) fastened on a dividing wall (1), it is proposed to illuminate the adjusting knob (4) by means of transmitted light by providing as a light guide (20) a conical ring (28) formed with continuations (29, 30, 31) formed on in the axial direction, the continuations (29, 30, 31) reaching through the dividing wall (1) and being aligned with light-emitting diodes (8, 9), which are located on a printed-circuit board (6) assigned to the rotary switch (7). The light guide (20) is fastened on the dividing wall (1) indirectly by fastening the housing (3) and is secured against twisting by suitable indentations (47, 48, 49) in the dividing wall (1).
