  • Patent number: 10992381
    Abstract: A method is provided for transmitting information and a device for carrying out the method, in which images are photographed by a camera with an image-taking rate, thus, especially frame rate, a controllable illuminant being disposed in the responsive range of the camera, where the control frequency (f_PWM) of the illuminant is less than the image-taking rate f1.
    Type: Grant
    Filed: September 1, 2014
    Date of Patent: April 27, 2021
    Assignee: SEW-EURODRIVE GMBH & CO. KG
    Inventors: Zhidong Hua, Christoph Steffen Keppler, Henning Schäfer, Andreas Wanjek
  • Patent number: 9810531
    Abstract: A system for an installation and a method for operating a system, including stationary transceiver modules and a vehicle having a transceiver module, the individual transceiver module having a controllable light source and a light sensor, so that a data transmission is able to be carried out between the vehicle and the stationary modules.

  • Publication number: 20130199463
    Abstract: The present invention relates to an energy-conversion system comprising an internal combustion engine (1) and a generator (2) which is driven by the internal combustion engine, and comprising a rotational connection which couples a first shaft (3) of the internal combustion engine (1) to at least one second shaft (5) of the energy-conversion system, wherein the second shaft (5) rotates in the opposite direction to the first shaft (3) and the first shaft (3) is arranged parallel to the second shaft (5), wherein products of moments of inertia and respectively associated rotational speed ratios of individual rotating components, which are rotationally coupled to one another by means of the rotational connection, at least approximately cancel one another out.
