Abstract: A method for wireless time synchronization of a first electrical unit with a second electrical unit is disclosed, which can in particular be intermittently wirelessly connected to each other, in particular via a low-energy connection, wherein the first electrical unit includes a first time counter and the second electrical unit comprises a second time counter, and wherein a connection event occurs repeatedly at predetermined connection time intervals.

Abstract: A switching device for a transmission of a motor vehicle includes an unsynchronized claw switching element that has a first switching part and a second switching part which are rotatable relative to each other around an axis of rotation. The first switching part has a first switching gearing and the second switching part has a second switching gearing which are displaceable relative to each other along the axis of rotation between a coupled position and an uncoupled position. Rotation positions in which the first and second switching parts are rotated relative to each other are detectable by a detection device. An electronic computing device moves the first and second switching parts from the uncoupled position into the coupled position depending on detected rotation positions. The detection device has a sensor element and a transmitter element, with transmitter segments, fixedly connected to the second switching part.

Abstract: A composite structure for stab protection includes layers of flat structures placed on top of each other, and an embedding material, wherein, in at least some of the layers placed on top of each other, the flat structures of adjacent layers are offset relative to one another, the flat structures of the composite structure are at least partially embedded in the embedding material, and the composite structure includes separated connecting elements, wherein before they are separated, the separated connecting elements have connected at least some of the flat structures of adjacent layers with one another.

Abstract: The invention relates to a rod-shaped fiber composite material (400) composed of a matrix (412) and a circular braid (402) embedded into the matrix. To increase the stability of the fiber composite material (400) and also to perform ducting functions for electricity and fluids, the wall of the circular braid is provided with wall chambers (408) which are separated by a phase boundary from the matrix (412) of the fiber composite material (400). These wall chambers (408) lead to inner and outer sections of the wall of the circular braid (402) being spaced apart, which is useful for the stability with regard to flexing and torsional loading in particular. Rod-shaped fiber composite materials (400) according to the invention can be used for creating stable structural components as well as for producing efficiently protected ducts. The invention further relates to an apparatus and a process which are useful for producing fiber composite material according to the invention.

Abstract: Method and arrangement for manufacturing core composite layer workpieces (sandwich structures) from at least one first and at least one second cover sheet (1, 2) between which a core sheet (30) including especially short cut fibers (9) is provided, are disclosed with which a continuous and substantially break free manufacture can be conducted which leads to composite layer structures with reasonable costs. Single manufacturing parameters can specifically be varied with different embodiments so that in a relatively simple manner composite layer structures with desired physical properties can be obtained, for example with respect to their strength, stiffness, flexibility, mechanical and acoustic absorption capabilities, working properties, and so on. Composite layer structures for new applications can be manufactured as well.
