In order to eliminate play between the insertion tube and the splint, the insertion tube is pressed against the splint by a pressure piece. A first segment of the pressure piece fits the inner diameter of the receiving tube, so that the pressure piece can be held by said receiving tube, while a second segment engages precisely in the insertion tube in order to be held thereby. | 10-21-2010 |

| 20100262328 | Method and Apparatus for Influencing the Transverse Dynamics of a Vehicle - In a method and apparatus for influencing transverse dynamics of a vehicle, for a chassis intervention is carried out when an intervention condition is met. The intervention condition is met when the value of a determined transverse dynamics disturbance variable is higher than a disturbance variable threshold value, and when one or a group of the following criteria is met:

| 20100261046 | Heat Exchanger Unit and Electrochemical Energy Accumulator with a Heat Exchanger Unit - A heat exchanger unit for an electrochemical energy accumulator, comprising flow channels, through which a temperature control medium flows. Ends of the flow channels are provided with flow distributor channels, which supply the flow channels, and/or return flow collection channels, and which collect the medium. A flow distributor is connected upstream of the flow distributor channels and a return flow collector is connected downstream of the return flow collection channels. The flow distributor and the return flow collector are separated from, and lie opposite, each other. A supply opening is located centrally on one of the lateral surfaces of the flow distributor and a drain opening is located centrally, on one of the lateral surfaces of the return flow collector. | 10-14-2010 |
| 20100259034 | Restraint System for a Motor Vehicle - The invention relates to a restraint system for a motor vehicle that is formed by one or several supporting structures, wherein the longitudinal extension of a supporting structure in the active state substantially exceeds the dimensions of the transverse extension and the supporting structure unfolds mainly in the direction of its longitudinal extension. So as to improve the restraint system such that the variables of the restraint system are adapted to the respective load, it is suggested that, during unfolding, the supporting structure ( | 10-14-2010 |
| 20100255388 | Fuel Cell System and Method of Operating a Fuel Cell System - In a fuel cell system a specific connection and a valve arrangement make it possible for a compressor to supply precompressed air to a fuel cell stack via a waste gas line, said air then leaving the fuel cell stack via a line which is otherwise an air feed line. In this way, a humidifier may be bypassed. This is sensible in particular during a start phase at low ambient temperatures, during which the fuel cell system is intended to warm up without moisture in the fuel cell stack having a negative effect, for instance by freezing. The compressor may be operated both in the start phase or stop phase and during conventional operation by the same mode of operation. | 10-07-2010 |
| 20100255235 | METHOD FOR PRODUCING A FIBER COMPOSITE HOLLOW BODY HAVING A FIBER ORIENTATION OPTIMIZED FOR FORCE FLOW AND TENSION - A method for producing a fiber composite hollow body, particularly a hollow fiber composite component for a motor vehicle. The hollow body is produced by a) applying and fixing continuous reinforcement fibers to a form corresponding to the later shape of the hollow body, wherein the arrangement of the fiber material with regard to the fiber composite hollow body takes place so as to optimize force flow and tension along a pre-defined load path, b) impregnating the reinforcement fibers with a curable resin, c) curing the applied resin to form a fiber composite component, and d) dissolving, melting, or removing the lost form to form the fiber composite hollow body. The lost form has a complex geometry. The fibers, which may be impregnated, are placed tightly onto the surface of the lost form, completely forming the surface contour. | 10-07-2010 |
| 20100253258 | Method and Device for Calibrating a Position Sensor Placed on a Shaft of a Permanent Magnet Synchronous Motor - In a method and apparatus for calibrating a position sensor mounted on the shaft of a permanent magnet synchronous motor, to control the position of a rotor of the permanent magnet synchronous motor relative to a magnetic field produced by a stator of the permanent magnet synchronous motor, a DC test current is supplied to stator windings of the permanent magnet synchronous motor to generate a definite magnetic field. The motor speed caused by the DC test current is adjusted to zero by modifying the rotor position; and the position measured by the position sensor at zero motor speed relative to the magnetic field is used to calibrate the position sensor. | 10-07-2010 |
| 20100252344 | Method for Controlling an Output Torque of an Electric Variable Transmission by Battery Power Management - In a method for controlling an output torque of an electric variable transmission having an input coupled to a combustion engine and at least one electric motor that is at least feedable by a battery and able to recuperate energy into the battery, the battery power is limited to a maximum continuous battery power when the transmission is in a stationary operating point with a continuous revolution speed. The battery power is increased and limited to a maximum transient battery power that is greater than the maximum continuous battery power in a non-stationary operating point, upon a request for changing the gear-ratio (ratio between transmission input and output-speed) or upon a request for changing the transmissions output revolution speed. | 10-07-2010 |
| 20100248888 | TANDEM AXLE HAVING TWO DRIVABLE AXLES AND A DRIVETRAIN WHICH CAN BE PARTIALLY DISCONNECTED - A tandem axle having two drivable axles, each axle including a differential gearing with a drive input gearwheel, drivable by a shaft, as a differential gearing input and with two drive input semi-axles driving the wheels of the axle using axle shaft wheels. The wheels of the first axle are permanently positively coupled to the drive input gearwheel of the axle. An activatable distributor wheel is seated on a drive input shaft of the drive input gearwheel of the first axle. The distributor wheel meshes with a through drive shaft wheel which is arranged in a rotationally rigid fashion on a through drive shaft. The output of the through drive shaft is coupled to the input-side drive input gearwheel of the second axle by means of intermediate members. Switchable clutches are arranged in the second axle between the axle shaft wheels and their adjacent wheels. | 09-30-2010 |
