  • Patent number: 9977095
    Abstract: A method and a device for the diagnosis of faulty light emitting diodes in a string (2) formed of at least two light emitting diodes. The light emitting diodes (3) are divided into at least two groups and an electrical measured variable is determined for each group with respective measurement units. Differences between the measured variable and a reference value are established per group and, by way of a diagnosis unit that is connected to the measurement units, a defect of a light emitting diode is identified on the basis of the ratio of the differences in the groups and signaled.

  • Publication number: 20180109190
    Abstract: The disclosure relates to a DC-DC converter in which a first coil terminal is connected with an input terminal and a second coil terminal is connected, on the one hand, via a rectification switch to an output terminal and, on the other hand, via a control switch to a ground potential and a control circuit is configured to switch in successive switching cycles in each case in a regulating phase the rectification switch to be electrically blocking and the control switch to be electrically conducting, and in a rectifying phase to switch the control switch to be electrically blocking. A measuring component generates a measurement signal which signals a current intensity of a coil current, and a comparator circuit compares the measurement signal with a threshold value and the control circuit keeps the rectification switch electrically blocking in the rectifying phase and conducts the coil current via a bypass diode if the current intensity was continuously lower than the threshold value in the regulating phase.

  • Publication number: 20180017118
    Abstract: A disc brake, having a brake caliper which engages over a brake disc, is held on a stationary brake carrier such that it can be displaced axially in relation to the brake disc, and in which brake pads are positioned which, during a braking operation, can be pressed against the brake disc by a brake application device. A device for visual wear detection of brake disc wear and/or brake lining wear is provided, and is configured in such that, for wear detection, a comparison element which extends in the displacement direction of the brake caliper and in an opposed manner with respect to the brake disc is fastened to the brake carrier. The comparison element is of strip-shaped configuration, with continuously planar side surfaces, and has at least one step on the edge side in the displacement direction of the brake caliper.
