Abstract: A light module of a lighting device of a motor vehicle including at least three optical elements for deflecting the light beams emitted by the light source arranged in succession in the beam path of the emitted light that produces a pre-defined light distribution on a lane in front of the motor vehicle. The first optical element comprises a first reflector element, which reflects the light beams emitted from the light source, the second optical element, which is arranged downstream from the first reflector element in the beam path, comprises a second reflector element and the third optical element, which is arranged downstream from the second reflector element in the beam path, comprises a lens element which, in cooperation with the second reflector element, projects the light beams previously deflected to the two reflector elements to realize the predefined light distribution on the lane in front of the motor vehicle.

Abstract: For the determination of the welding current to be used for the resistance welding of the overlap seam of container bodies, welding with a test body is carried out with a changing strength of welding current which in the test body produces a varying welding of the seam. The current strength varies from welding of this seam with a too high temperature to welding with a too low temperature. Along with this the welding current strength used in the welding is determined so that it is further determined at which point of the seam the welding has been accomplished and with what strength of welding current. By means of a mechanical and/or optical investigation of the welded seam it can then be easily determined where the seam has been correctly welded for the series production of container bodies from the same sheet material as the test bodies. When such a point or such a region of the seam is known the welding current used in the test welding can be taken as the welding current for serial production.

Abstract: A visualization system and method for visualization of network data, which is data that represents elements and links between elements. The network data is converted into a data structure, which represents a grid arrangement of the elements, where each element is placed on an individual grid position of a lattice. The data structure is suitable for use by a graphics display. The visualization tool comprises a processing unit that generates an initial data structure which represents an initial grid arrangement of the elements. It then assigns a global value to this initial grid arrangement and employs a gradient method for converting the initial grid arrangement into another grid arrangement which has a decreased or an increased global value.
