Abstract: A damping apparatus for a drivetrain of a motor vehicle, with a first damping element which is rotatable about an axis of rotation, a second damping element which can be driven by the first damping element and is thereby rotatable about the axis of rotation, at least two damping chambers, the volumes of which can be modified by a relative rotation between the damping elements, at least one overflow channel, by which the damping chambers are connected to one another fluidly, and having a damping fluid, which flows from one damping chamber into the other damping chamber via the overflow channel upon a volume reduction of one of the damping chambers. The overflow channel flowing into the respective damping chambers at both ends is formed by a gap between the damping elements, the gap being directly limited by the damping elements, at least in a lengthwise region.

Abstract: An apparatus is provided for wirelessly charging a mobile computing device and utilizing the mobile computing device as a power source. The apparatus includes: a first data and power interface; a second data and power interface; a wireless charging unit; and a control unit. The operation of the wireless charging unit and the control unit is configured to provide a first mode of operation of the apparatus when an external source connected to the apparatus via the second data and power interface is a load device in which power is delivered from the mobile computing device to the load device via the first and second data and power interfaces, and a second mode of operation of the apparatus in which power is delivered from a power receiver of the wireless charging unit to the mobile computing device via the first data and power interface.
