Abstract: Disclosed is a popup camper having a base, a top, a first sidewall having a first edge, a second sidewall having a second edge, a third sidewall connected to the first sidewall at the first edge, connected to the second sidewall at the second edge, connected to the top at a third edge, and connected to the base at a fourth edge, a hinge connecting the base and the top, the hinge opposite the third sidewall, wherein the top can be disposed in an open position or a folded position, wherein in the open position the top is hingedly rotated away from the base to form an interior space between the top, base, first sidewall, second sidewall, and third sidewall, and wherein in the folded position the top is hingedly rotated towards the base collapsing the interior space.

Abstract: The present disclosure relates to a motor vehicle comprising at least one illumination device, by means of which at least one light signal can be generated which is visible from outside the motor vehicle, and comprising at least one acoustic device, by means of which at least one acoustic signal can be generated which is audible from outside the motor vehicle. The at least one control device of the motor vehicle is configured to check whether at least one output condition is satisfied and, if the at least one output condition is satisfied, to control the at least one illumination device and the at least one acoustic device in such a way that the light signal and the acoustic signal are generated simultaneously.

Abstract: An electronic device with a multi-layer contact and a system is disclosed. In an embodiment, a semiconductor device includes a semiconductor substrate having a first electrode terminal located on a first surface and a second surface electrode terminal located on a second surface, the first surface being opposite to the second surface, an electrical contact layer disposed directly on the first electrode terminal, a functional layer directly disposed on the electrical contact layer, an adhesion layer directly disposed on the functional layer, a solder layer directly disposed on the adhesion layer; and a protection layer directly disposed on the solder layer, wherein the semiconductor device is a power semiconductor device configured to provide a vertical current flow.

Abstract: A method and apparatus for powering an electronic circuit use comparators of supply voltages and voltage regulators to facilitate powering the electronic circuit utilizing more than one supply voltage. In one embodiment, power supplies of step-up power units are controlled using comparators of step-down power units and the step-up power units temporarily provide power to accidentally disabled of step-down power units.

Abstract: A hierarchical network management system is described which includes concentrators (2A to 5A) on the individual levels (E1 to E3) of the hierarchy as well as adjustable interfaces in the concentrators for point-to-point and bus connections. An interface is provided for a bus connection on a master side. The interface takes delays into consideration. A transmission channel can be connected to the interface. The channel includes a forward bus and return line (a5, b5). Parallel addressable apparatus (8A, 8B, 8C) can be connected to the forward and return lines. A controllable change-over switch (A8, B8, C8), inserted in the return line (b5) of the transmission channel, is provided for each addressable apparatus (8A, 8B, 8C) of the parallel combination.

Abstract: The invention relates to a phase-locked loop comprising a phase detector (PD), an analog-to-digital converter (ADC), a loop filter (LF), a digital-to-analog converter (DAC) and a voltage-controlled oscillator (VCO). The phase jitter that occurs in such a hybrid phase-locked loop is reduced without enhancing the requirements as to the resolution of the digital-to-analog converter (DAC), in that a fractionizer (FR) is inserted after the loop filter (LF) that is operating at a first clock (TL), which fractionizer produces a main value (HW) and a residual value (RW), and the sum (SW) of the main value (HW) and a correction bit (KB) derived from the residual value (RW) is applied to the digital-to-analog converter (DAC) that is operating at a second clock (TA).

Abstract: In a single- or multiple-part protective cover for traction drives (for instance, chain, belt, toothed belt drives or the like), in particular for vehicle engines, vehicle drives, machines or the like, a protection of the traction drive from impairment by excessive heating during operation and from the entry of dirt particles, rainwater, snow and other foreign bodies is attained in that at least one coolant overpressure inlet opening (2) is embodied in the walls of the protective cover (1) and communicates with at least one source emitting the pre-filtered coolant at overpressure.
