Abstract: A dynamoelectric machine includes a shaft, a rotor arranged fixedly on the shaft for conjoint rotation, and a slip ring system enabling a rotor winding system to be contacted electrically and including a slip ring body having slip rings arranged spaced-apart axially behind one another and assigned to an electrical phase. The slip ring body is connected fixedly to the shaft for conjoint rotation and has between an inner side thereof and the shaft a section which forms an axially open cavity on both skies. In a region of the slip ring system, the shaft is hollow with a hollow shaft portion assigned to the slip ring system for routing feed lines to the rotor winding system. Recesses are provided on the cavity axially on an inside and axially on an outside for introducing a cooling medium flow axially into the cavity and discharge thereof into an outlet region.

The turning unit includes a manipulator embodied to lift the bottom side of the workpiece off the receiving surface, to perform a turning operation of the workpiece and to place the top side of the workpiece on the receiving surface of the conveyor.

Abstract: Systems and methods of a safety helmet for protecting the human head against repetitive impacts, moderate impacts and severe impacts so as to significantly reduce the likelihood of both translational and rotational brain injury and concussions can be provided. The helmet can include an outer shell, an outer liner disposed within and coupled to the outer shell, and an inner liner disposed within and coupled in spaced opposition to the outer liner. A polymer liner can be coupled to the inner liner and can at least partly separate the outer liner and the inner liner. Pads and dampers can also couple the outer liner and inner liner and provide for and control omnidirectional movement of the liners relative to each other.

Abstract: A radar system for motor vehicles, with a plurality of transmit/receive units arranged on separate installation supports for installation at various locations in the motor vehicle, an evaluation system for evaluating the radar signals received on a plurality of channels in a plurality of processing steps, a first processing step delivering a digital time signal for each channel, which digital time signal represents the received radar signal, and a final processing step delivering as the result location data for individual radar objects and at least the final processing step being implemented for the plurality of transmit/receive units in a central evaluation unit with which the transmit/receive units in each case communicate via a raw data interface. The each of raw data interfaces has a serializer, which is configured to transfer raw data from the plurality of channels of the transmit/receive unit in question serially to the central evaluation unit.

Abstract: Systems and methods of a safety helmet for protecting the human head against repetitive impacts, moderate impacts and severe impacts so as to significantly reduce the likelihood of both translational and rotational brain injury and concussions may be provided. The helmet may include an outer shell, an outer liner disposed within and coupled to the outer shell, and an inner liner disposed within and coupled in spaced opposition to the outer liner. A damper array may allow for omnidirectional movement of the inner liner relative to the outer liner and the outer shell.

Abstract: Systems and methods of a safety helmet for protecting the human head against repetitive impacts, moderate impacts and severe impacts so as to significantly reduce the likelihood of both translational and rotational brain injury and concussions can be provided. The helmet can include an outer shell, an omnidirectional liner disposed within and coupled to the outer shell and configured to move relative to the outer shell, and a chinstrap coupled to the omnidirectional liner. The chinstrap coupled to the omnidirectional liner can hold a wearer's head to the omnidirectional liner and prevent the chinstrap from applying forces to the wearer while omnidirectional liner moves relative to outer shell. Other embodiments may include a chinguard with a movable chincup.

Abstract: A mouthpiece a device for measuring a parameter of respiratory air. The mouthpiece including an end edge of a wall of the mouthpiece, and the end edge is configured to delimit an opening for blowing respiratory air into the mouthpiece. An opening surface of the opening extends transversely with respect to a flow axis of respiratory air blown into the mouthpiece. A contour of the opening forms a D shape or a lens shape, seen in the direction of the flow axis. The opening is delimited by a first opening portion and by a second opening portion adjoining the first opening portion.
