The channel is adapted to receive a portion of the bipolar plate. The contact body has a contact spring on a first channel wall of the pair of channel walls. The contact spring protrudes into the channel and has a cutting edge directed toward a second channel wall of the pair of channels walls and adapted to contact the bipolar plate.

Abstract: A heads-up projection device configured to be arranged on or in a helmet, for detecting and processing data and for reproducing the data in a virtual image within the view field of an eye of a user of the helmet. The device comprises a housing in which operating elements are arranged for detecting and processing data and/or reproducing the data in an imaged manner, and a combiner panel arranged on the housing. The housing is elongated and has a curved geometry such that the housing can be arranged substantially in the front region of the helmet above the eye(s) of the user, and the combiner panel can be positioned in front of the eye of the user. Also described is a helmet configured for arranging the heads-up projection device on or in the helmet.

Abstract: A socket contact includes a receptacle receiving a plug contact, a base body surrounding the receptacle at least in sections, a contact element disposed in the receptacle and contacting the plug contact, and a spring device creating a contact normal force at the contact element. The spring device is formed as a part of the base body that surrounds the contact element. The spring device is arranged at a first part and the contact element is arranged at a second part separate from the first part.

Abstract: A socket connector assembly is provided and includes a body, a socket connector and a force fit assembly. The socket connector is positioned in the body and includes a socket frame. The socket frame includes an upper side, a lower side positioned opposite the upper side, and a spring assembly connecting the upper side and lower side such that the upper side is moveable relative to the lower side along a height direction. The force fit assembly secures the body to the socket connector.

Abstract: A contact assembly for an electrical connector is provided and generally includes a plurality of first contact bodies and a plurality of second contact bodies. The plurality of first contact bodies include contact surfaces that provide a first contact plane. The plurality of second contact bodies include contact surfaces that provide a second contact plane that is spaced apart from and projecting beyond the first contact plane by a height. The plurality of second contact bodies are elastically deflectable to the first contact plane.

Abstract: An emergency call unit for a vehicle includes not only a detection unit, a position-finding unit and a control unit, but also a transmission unit for the repeated transmission of a locating signal to a rescue worker. In this context, the locating signal may correspond to the position of the vehicle, and the transmission of the locating signal is initiated by a trigger event. By way of example, the trigger event is a request from a rescue worker or is the detection of an accident.

Abstract: A mounting device for solar modules having a large aspect ratio in a parallel arrangement on a flat horizontal substrate includes mounting rails having through-holes at predetermined locations. Insertion elements are attached to the mounting rails at the through-holes. Each insertion element includes a one-piece shaped element having a contiguous surface interrupted by an insertion slit configured to receive a lengthwise edge area of a solar module, the insertion slit extending at a predetermined insertion angle. A plastic wedge is configured to secure the received lengthwise edge area of the solar module in the insertion slit.
