Abstract: A contact element for contacting a bipolar plate of a fuel cell stack includes a contact body extending along a longitudinal axis. The contact body has a channel extending along the longitudinal axis and delimited by a pair of channel walls disposed opposite one another in a direction transverse to the longitudinal axis. 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.
