  • Patent number: 10078961
    Abstract: A traffic-infrastructure unit and a method for operating a traffic-infrastructure unit encompassing a signal source, the method having a step of detecting at least one vehicle, a step of detecting at least one further road user, a step of determining a danger potential for the at least one further road user due to the at least one vehicle, and a step of operating the traffic-infrastructure unit as a function of the determined danger potential.
    Type: Grant

  • Patent number: 9689458
    Abstract: A vibration damper for a sensor unit comprises an elastic damping element including a central plate, a plurality of damping fingers joined at a first end to the central plate, and a plurality of fastening surfaces. At least two fastening surfaces of the plurality of fastening surfaces are disposed at a distance from each other in a first spatial direction. The damping element is flexurally elastically soft along the first spatial direction and is formed with a higher stiffness in a main extension plane defined perpendicular to the first spatial direction. A layer of adhesive is applied to each of the at least two fastening surfaces which are configured to be subjected to shear stress as a result of vibrations in the main extension plane.

  • Patent number: 8475150
    Abstract: The invention relates to an internal gear pump for a brake system, in the pump housing of which an internally toothed ring gear and a pinion meshing with the toothing of the ring gear are pivotally supported about parallel axes. As a result the toothing thereof limits an approximately crescent-shaped tapering annular space, in which a filler piece supported toward the intake side of the pump is arranged. The circumferential sides of the filler piece are bent in accordance with the addendum circle of the ring gear toothing or of the pinion toothing. The sides rest against several tooth tips in a sealing manner under a spring force. According to the invention, one of the two circumferential sides of the filler piece is formed by a radially resilient circumferential wall, which is nestled against the tooth tips of the pinion or the ring gear due to the deflection based on the inherent spring force thereof.
