Abstract: A torque transmission device for a powertrain of a motor vehicle has an input area and an output area. A torque path runs from the input area to the output area. A torsional vibration damping unit is positioned first, followed by a gear unit, along the torque path between the input area and the output area. The torsional vibration damping unit provides a first spatial area and an adjoining second spatial area along the torque path, and the gear unit provides an adjoining third spatial area.

Abstract: An implantable, autonomously growing medical device is disclosed. The device may have an outer, braided outer element that holds an inner core. Degradation and/or softening of the inner core permits the outer element to elongate, allowing the device to grow with surrounding tissue. The growth profile of the medical device can be controlled by altering the shape/material/cure conditions of the inner core, as well as the geometry of the outer element.

Abstract: A mass damper system has a damper mass carrier and a damper mass movably received at the damper mass carrier a lubricant supply, a lubricant collector, and a lubricant distributor radially offset to one another with the damper mass carrier, the lubricant supply arranged at a shorter radial distance from a central axis than the lubricant collector, and the lubricant distributor arranged at a greater radial distance from the central axis than the lubricant collector to collect lubricant supplied by the lubricant supply and to guide the lubricant through the lubricant distributor to the damper mass. A stop arrangement limits a deflection path of the damper mass relative to the damper mass carrier, and the lubricant distributor has a lubricant feed that leads from the lubricant collector to a constructional unit requiring intensive lubrication.
