  • Publication number: 20180229775
    Abstract: A system that mounts a motor vehicle hood on a body of the vehicle includes a guide element to slidably guide the hood relative to the body in a longitudinal direction of the vehicle and a locking element to lock the hood to immobilize the hood relative to the body in a closed position, in which it seals off an engine compartment. The locking element assumes an activated state as a result of a sliding movement of the hood relative to the body in the longitudinal direction of the vehicle in a first direction. The guide element includes a self-centering element to self-center the hood relative to the body in a direction transverse to the vehicle while the hood slides in the first direction, and ensures that the closed position of the hood is a predetermined position in the transverse direction and is constant relative to the body.

  • Patent number: 10027000
    Abstract: An accumulator battery system includes series-connected accumulators with potentials across stages powering corresponding controllers that measure potential differences between terminals of accumulators. A first analog-to-digital converter encodes the potential measured between terminals of an accumulator. A first output delivers a first digital sequence corresponding to the encoded potential difference, logic levels of which are defined by at least two potentials across the first-stage accumulator terminals. A decoder decodes a potential measured by the first control-device from the first digital sequence. A second analog-to-digital converter selectively encodes a potential difference measured between terminals of a second-stage accumulator of the second stage and two potentials of the digital sequence received on the input.
