Abstract: ? method for determining a vehicle body movement of a vehicle body of a vehicle (1) which comprises a camera (3) arranged on the vehicle (1). Camera images of vehicle surroundings are thereby continuously recorded by means of the camera (3) and image position data of at least one static object (8) are determined in camera images recorded at different times. Using the time-based sequence of the determined image position data the vehicle body movement is determined. Further, a method for determining a spring compression movement of at least one wheel (7), mounted in a sprung fashion, of a vehicle (1) which comprises a camera (3) arranged on the vehicle (1).

Abstract: A fuel cell system includes at least one fuel cell and at least one air conveyor that conveys a process air flow to the fuel cell. At least one heat exchanger is also provided, through which the process air flow flows after the air conveyor and through which a cooling medium flow flows. A region with catalytically active material is arranged in the flow direction of the process air flow before or in the region of the heat exchanger. In addition a fuel can be fed to the region with the catalytically active material.

Abstract: A method for operating a powertrain, including an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and an electric machine, includes monitoring slip across a selectively applied clutch within the transmission to indicate a clutch slip event, and if the monitoring indicates the clutch slip event decreasing a load across the selectively applied clutch by reducing torque of at least one of the engine and the electric machine, in order to reduce the slip, thereby ending the clutch slip event.

Abstract: The present invention relates to a sandwich component, which comprises a honeycomb core (1) having a plurality of webs (1?) and at least one cover layer (2, 3), wherein the honeycomb core (1) is made of a cellulose-based material, in particular paper. The cover layer (2, 3) is formed from a fiber-reinforced semifinished product having a thermoplastic material matrix, wherein the webs (1?) of the honeycomb core (1) are partially received into the thermoplastic material matrix of the cover layer (2, 3) at connection points (A) to the cover layer (2, 3) so that the sandwich component is bonded. The invention further relates to production methods for the sandwich component.

Abstract: A conduit coupling includes first and second conduits, an annular adapter and a clamp. The first conduit has an annular flange on an outer surface adjacent to a first end. The adapter is coupled to the outer surface of the first conduit and has an annular first engagement surface positioned adjacent to the flange and an annular second engagement surface that is spherical and convex. The second conduit has a flared end with an inner surface and an outer surface. The inner surface includes an adapter engagement surface that is spherical and concave and engageable with the second engagement surface. The outer surface includes a clamp engagement surface and the clamp includes a flared end engagement surface that is engageable with the clamp engagement surface. The clamp is configured to urge the flared end, adapter and annular flange together.

Abstract: An assembly unit with an industrial robot for handling a vehicle body is provided. The industrial robot can be moved by coupling to the vehicle body in the conveying direction, in which a conveyor belt conveys the vehicle body. The industrial robot retains in any conveying situation its exact position relative to the workpiece in all directions. A transport platform serves to transport the industrial robot. The transport platform can be moved independently of the conveyor belt and without use of rails if the industrial robot is decoupled from the vehicle body. A component storage unit can be coupled to the transport platform. The component storage unit then can also be moved by the transport platform. The industrial robot can be designed for a small load to achieve a cost-effective assembly unit.

Abstract: A method for welding two metal parts from aluminium alloys with the steps: melting of the metal parts to be joined in a weld region through an energy input by means of a laser beam with the formation of a weld seam, smoothing the surface of the weld seam through a further energy input with partial melting of the weld seam in the region of the surface, wherein the further energy input is a defocused laser beam, of which the focal point is positioned in the beam direction in front of or behind the surface of the weld seam, wherein the defocused laser beam and the surface normal of a surface of the two metal parts to which the laser beam is applied, incorporate an angle of greater than or equal to 5 degrees, and a connecting arrangement welded with this method.

Abstract: A restraint system for a motor vehicle is formed by one or more inflatable supporting structures whose longitudinal extent in the deployed state substantially exceeds their transverse dimension, and which unfold mainly in the direction of their longitudinal extension. During unfolding, the supporting structure, when impacting upon an obstacle does not have the same stability as when it is completely unfolded, and/or does not reach the final volume or the final extension.

Abstract: A powertrain system includes a hybrid transmission device operative to transfer power between an input member and torque machines and an output member in one of a plurality of operating range states. The torque machines are connected to an energy storage device. A method for operating the powertrain system includes determining a permissible range of input operating points to the input member, determining ranges of motor torques for the torque machines, determining an available power range from the energy storage device, selecting a candidate input operating point within the permissible range of input operating points, and determining maximum and minimum achievable output torques transferable to the output member for the candidate engine operating point within the ranges of motor torques for the torque machines and within the available power range from the energy storage device in a candidate operating range state.

Abstract: The pressure drop associated with the coolant flow in the coolant transition regions of a typical high power density, solid polymer electrolyte fuel cell stack can be significant. This pressure drop can be reduced by enlarging the height of the coolant ducts in this region of the associated flow field plate so that the ducts extend beyond the plane of the plate. The height change can be accommodated by offsetting the ducts in adjacent cells in the stack and by employing non planar MEAs in this region. By reducing the pressure drop, improved coolant flow sharing is obtained.
