Abstract: In a method for determining a course of a traffic lane for a vehicle (10), structures that demarcate a trafficable space are detected in image data from an image acquisition unit (2), and these structures are plotted on a surroundings map (20) that subdivides the surroundings of the vehicle into a two-dimensional grid (20a) of cells (21). The position of the vehicle in the grid of the surroundings map is determined and updated by odometric data. The distance and the direction of the vehicle (10) relative to those cells (21b) of the grid (20a) having structures that demarcate the pavement and/or the traffic lane are determined. Brightness transitions in the image data are detected and are plotted on the cells (21) of the grid (20a). The course of the traffic lane (22) is determined from the cells with the detected brightness transitions.

Abstract: The invention provides a rotation transformer for a cable connection including separation discs rotatable about a longitudinal axis. In use, one end of a cable executes a limited number of revolutions about the longitudinal axis in relation to the other end while maintaining an uninterrupted connection between the two ends. The distance between the rotatable separation discs is measured such that a maximum of two coils of the cable lie on one plane between two separation discs. The cable is guided through the discs without converging and is wound alternately from the outer diameter of a disc to the longitudinal axis and vice versa between the pairs of separation discs.

Abstract: The invention creates a technology for validating simulation results. The quickly growing number of components in modern complex systems often necessitates the introduction of abstractions, that render said systems manageable. However the abstractions, which often are based simplified assumptions, may impair the simulation results. The automatic post-processing method according to the invention safeguards the validity of the result. In most cases this can be reached, without restoring the complete description, which generally is too complex. The method, which is described for the validation of calculated counter-examples in an equivalence comparison of digital circuits can be used in all other applications, that allow for an analagous formalization of the abstraction step.

Abstract: A device for producing sponge iron from iron oxide lumps consists of a reduction shaft in which a hot dust laden reducing gas is delivered. The gas is produced in a gas generator by means of partial oxidation of solid carbon carriers and passes into the lower end of the reduction zone via lateral reduction gas inlets. The iron oxide lumps are fed to the upper area of the reduction shaft and are radially fed as sponge iron to the lower end of said reduction shaft via delivery organs. The delivery organs are arranged in such a manner that the sponge iron is conveyed only radially outwardly.

Abstract: An ink duct for use with a screen roller which comprises a working doctor blade and a closing doctor blade, wherein the working doctor blade has one or both sides partially or completely coated with an unreleasable coating of a low surface energy substance having a surface energy of 10 to 60 mN/m. This coating prevents disruptive ink deposits from forming on the side of the working doctor blade opposite to the ink retaining portion of the ink duct and reaching the doctored surface of the ink metering roller in an uncontrolled or random manner.

Abstract: An ink duct for a rotary printing press wherein all or some of the surfaces of the ink duct are permanently coated with a substance which has a low surface energy of between 10 and 60 mN/m. As well as enabling the ink duct to be cleaned easily, the blending of the printing ink is improved owing to the reduced frictional resistance of the coated parts, which in turn leads to more uniform use of the ink-metering roller.
