Abstract: A turbine wheel for a turbine of an exhaust gas turbocharger includes at least one turbine blade against which exhaust gas can flow. The maximum ratio of the wheel outlet diameter of the turbine wheel to the thickness of the turbine blade is 111.75.

Abstract: The invention discloses a steering column arrangement that has a steering spindle and a casing tube enclosing the steering spindle, which may be mounted to be rotatable about a longitudinal axis relative to the casing tube, and also has a switch module, which has a housing and a fastening sleeve provided on the housing. The fastening sleeve is designed such that the switch module with the fastening sleeve can be mounted on the casing tube and can be securely clamped to the casing tube. The casing tube on an outer circumferential surface has at least one radial projection, and the fastening sleeve on an inner circumferential surface has at least one extending guide groove when viewed in the longitudinal direction. The radial projection engages the guide groove when the switch module is mounted on the casing tube.

Abstract: A ground pad module for charging a power-driven vehicle is designed to be arranged on an underground accessible to the vehicle. The ground pad module includes a fan unit arranged within the ground pad module and configured to cool at least one electrical and/or electronic assembly arranged within the ground pad module by an air flow that can be supplied to the ground pad module from an exterior area. An inlet channel of the air flow is designed such that if the ground pad module is arranged as intended, water penetrating through an inlet opening of the inlet channel must overcome at least one step in a component of a flow direction of the water before it reaches the fan unit and/or the assembly with the component facing a direction opposite to the force of gravity.

Abstract: Use of a selectively conducting anode component in solid polymer electrolyte fuel cells can reduce the degradation associated with repeated startup and shutdown, but can also adversely affect a cell's tolerance to voltage reversal along with its performance. It was shown that these adverse affects can be mitigated against in certain ways. However, improved results can be obtained by employing a selectively conducting component which comprises a mixed layer of a selectively conducting material and carbon. The mixed layer contacts the side of the anode opposite the solid polymer electrolyte.

Abstract: A grille for a vehicle is disclosed. The grille is configured to be arranged in front of at least one heat exchanger of the vehicle and includes a plurality of grille bars arranged at a distance from one other. A respective portion of each of the plurality of grille bars is airfoil-shaped.

Abstract: The invention relates to a method for producing a membrane electrode assembly (12) for a fuel cell, wherein at least one first component (18) of the membrane electrode assembly (12) is provided as part of a continuous material web which passes through a plurality of processing stations. At least one second component (26) of the membrane electrode assembly is connected to the at least one first component. At least one adhesive is applied to at least one of the components (18, 26), said adhesive causing the connection of the at least one first component (18) to the at least one second component (26). Furthermore, the invention relates to a device (10) for producing a membrane electrode assembly (12).

Abstract: A method for the determination of a speed vector for a gesture recognition system in a motor vehicle is disclosed. The method includes detection of movement data by a detection unit, and transmission of the movement data to a processing unit in the form of vectors. A totalling of the vectors to form a total vector occurs using the processing unit, until either the total vector reaches a predetermined minimum length or a predetermined number of vectors is totalled. If the predetermined number of vectors is totalled and the predetermined minimum length of the total vector is not reached, a determination of the speed vector as a zero vector occurs. If the predetermined minimum length of the total vector is reached, a determination of the speed vector occurs by averaging the information contained in the total vector. An accurate and dynamic determination of the speed vector is thereby achieved.

Abstract: A method for starting operation of a solid polymer fuel cell from a temperature below 0° C. is disclosed that prevents certain problems with ice formation as the fuel cell thaws. During startup, the method involves providing the volumetric oxidant flow at a rate less than two thirds of its maximum when the coolant temperature is near 0° C.
