  • Patent number: 10340061
    Abstract: A data line that is designed as a coaxial cable and has a line core that extends in a line longitudinal direction. The line core has at least one conductor surrounded at least by insulation and is surrounded by a multi-layer shielding foil, which has a non-conductive layer and a conductive layer. In an overlap region, a free end edge overlaps a further partial region, wherein additionally a conductive connection of the conductive layer at the end edge to the further partial region is formed such that a transverse current flow perpendicular to the longitudinal direction within the conductive layer is enabled. The conductive connection is formed optionally as a conductive strip and/or by a beveled end edge. In particular, the data line is a data line shielded exclusively via the shielding foil. The data line is used in particular in a motor-vehicle electrical system.

  • Publication number: 20190107574
    Abstract: A method for monitoring a line is done in a simple manner by feeding test pulses and determining any interference on the test pulses by reflected portions of the same test pulses. In a normal state of the line, the measuring pulses have a transit time which is known in advance due to the predetermined length of the line, and the respective reflected portions of the measuring pulses are generated which propagate in an opposite direction to the measuring pulses. A deviation of the transit time from a previously known transit time, and a deviation from the normal state are recognized in dependence on the overlay.

  • Publication number: 20180274170
    Abstract: In a method for producing a braid that extends in a longitudinal direction, multiple individual strands are interwoven with one another. For this purpose, first and second spools are moved relative to one another, the individual strands being wound onto the spools. The first spools having first individual strands are guided on a path that circulates about the longitudinal axis with the result that the first individual strands are arranged in a helical manner at least in sections about the longitudinal axis. The second spools having second individual strands are arranged with respect to the direction of rotation at fixed angular positions with the result that the second individual strands are incorporated into the braid in a manner in which they extend parallel to the longitudinal direction.

  • Patent number: 9871559
    Abstract: In order to permit, in a motor vehicle on-board power system, data to be transmitted with low expenditure on cabling, even between multiple partial networks, a plurality of loads embodied, in particular, as sensors is respectively assigned a communication unit for transferring data. The communication units are embodied in such a way that, by utilizing the supply lines they set up a partially interlinked data network, and transfer data made available by the loads, with the result that communication via the partial networks is also made possible. As a result of the transmission of the data via the supply lines in combination with the setting up of a partially interlinked data network, signal transmission is made possible even if there is no direct connection between the respective sensor and a target unit.
