    Abstract: 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.

  • Patent number: 10557449
    Abstract: A method for ascertaining a torque accuracy of a torque transmitted from a belt-driven starter-generator of an internal combustion engine to the internal combustion engine, which is similar to a learning process or a calibration of the actual torque of the starter-generator with respect to a setpoint torque, includes controlling the belt-driven starter-generator to transmit a specified test torque to the internal combustion engine during a predefined test time interval during coasting down of the internal combustion engine, determining a speed variable that is dependent on a speed of the internal combustion during the test time interval, comparing the speed variable to a reference variable, and deducing the torque accuracy from this comparison.
