Patent number: 11110852Abstract: A device for producing an output light emission having a light source for emitting light and a first polarizing beam splitter element positioned so at least one portion of the emitted light is incident thereupon, wherein a first reflected light beam of a first polarization state and a second transmitted light beam of a second polarization state are produced. The device also includes a first liquid crystal element having at least two states which are actuated using a control unit. The first liquid crystal element at least partially reflects the first light beam, wherein the polarization state of the first light beam is altered based on the state of the first liquid crystal element. The first polarizing beam splitter element is positioned so the first light beam is incident thereupon after reflection at the first liquid crystal element.Type: GrantFiled: May 4, 2018Date of Patent: September 7, 2021Inventors: Joscha Roth, Heiko Schröder, Sebastian Thomschke, Helge Neuner, Daniel Dias, Michael Schneider, Ralf Mayer, Bernd Ludewig

Patent number: 9221316Abstract: Roll stabilizers as an example for chassis actuators are used for compensating or suppressing rolling movements of a vehicle about its longitudinal axis. Such rolling movements are caused, in particular, when driving around curves due to centrifugal forces. A chassis actuator device is provided, in particular, a roll stabilizer, for a vehicle with a flange connection between an actuator and a stabilization component. A holder-side positive-locking contour is arranged on a holder section of the flange connection and a flange-side positive-locking contour is arranged on a flange. The positive-locking contours together form a positive-locking connection in the circumferential direction about a torsion axis A, and the flange-side positive-locking contour is arranged on a flange-side lateral surface and/or the holder-side positive-locking contour is arranged on a holder-side lateral surface.Type: GrantFiled: April 3, 2014Date of Patent: December 29, 2015Assignee: Schaeffler Technologies AG & Co.
