  • Patent number: 8101265
    Abstract: A combination instrument has a disk that is transparent for light in the visible range and that has a dial region and an indicator region. It further has a dial imprint, which is applied to the back of the transparent disk in the dial region. In addition, a polarizing filter disk is provided, which is disposed on the back of the transparent disk aligned with the indicator region and comprises a circular polarizing filter. An optical indicator unit is provided, which is disposed in alignment with the indicator region on the back of the transparent disk and the polarizing filter disk.
    Type: Grant

  • Patent number: 6480806
    Abstract: A system for automatic headlight leveling control in a motor vehicle has two level sensors which are offset in the longitudinal direction for measuring the vehicle body pitch angle in the form of a level difference. An electronic control unit determines a desired value for the headlight adjustment as a function of the first derivative of the directly measured or further processed level difference. In one embodiment of the invention, electronic control unit determines a static level difference and a dynamic level difference, and the desired value is determined as a function of the first derivative or the second derivative of the dynamic level difference.
