20100146174 | Method for Protecting Against External Interventions into a Master/Slave Bus System and Master/Slave Bus System - The method serves for protecting against external interventions into a master/slave bus system. The master/slave bus system contains at least one slave and at least one authorized master for outputting an authentic command. The authentic command instructs the slave to carry out a function. Accordingly, the authenticity of the command which has been transmitted over the bus is checked. The execution of the function is enabled only in the event of a positive check result. | 06-10-2010 |
20100132655 | INTERNAL COMBUSTION ENGINE - An internal combustion engine with a crankcase upper part and a crankcase lower part, wherein an oil windage tray is provided, which is flanged onto the crankcase upper part from below, projects into the crankcase lower part, forms a wall for an oil mist roller initiated by the rotation of a crankshaft, and includes at least one carpenter's plane-like slot for separating oil droplets. At least two slots are provided in the rotational direction of the crankshaft and thus in the rotational direction of the oil mist roller, wherein a return opening, through which oil mist-free gases or gases with at least a reduced oil mist content flow back, is provided in the wall of the oil windage tray after each slot, as a result of which friction is reduced. | 06-03-2010 |
20100126448 | VALVE DRIVE OF AN INTERNAL COMBUSTION ENGINE - A valve drive of an internal combustion engine with a camshaft including cams for actuating gas-exchange valves,
| 05-27-2010 |
20100126447 | VALVE DRIVE OF AN INTERNAL COMBUSTION ENGINE - A valve drive of an internal combustion engine, with a camshaft including cams for actuating gas-exchange valves, wherein at least one cam, which includes several cam faces, is guided nonrotatably but with freedom of axial movement on the camshaft; wherein a stroke profile, which cooperates with an actuating pin for the axial displacement of the cam or cam piece, is assigned to the associated axially displaceable cam or an axially displaceable cam piece comprising several cams; and wherein the stroke profile of the axially displaceable cam or cam piece in question includes intersecting stroke curves. A guide element is assigned to the end of the actuating pin which can be introduced into the stroke curve of the stroke profile of the associated axially displaceable cam or cam piece, this guide element being supported in such a way that it can rotate or pivot around the axis of the actuating pin. | 05-27-2010 |
20100123336 | MOTOR VEHICLE DOOR - A motor vehicle door has a triangular pane, a lowerable side pane, and a guide rail for guiding the lowerable side pane being provided between the triangular pane and the lowerable side pane. Here, the guide rail is fixedly connected to a window frame, to an inner window slot and to a mirror reinforcement. | 05-20-2010 |
20100123265 | METHOD FOR PRODUCING A DIMENSIONALLY STABLE INSCRIPTION - A three-dimensionally embossed inscription containing a plurality of interconnected letters is connected, for dimensional stability, to a holding frame during a manufacturing process via supporting elements. After the end of the machining and manufacturing processes, the inscription is separated from the holding frame and has a shape which corresponds to the connected shape on the holding frame. | 05-20-2010 |
20100117402 | Motor Vehicle Body - A motor vehicle body has at least two sills running laterally in a longitudinal direction of the vehicle. An auxiliary frame is provided in a region of a front axle and at least one strut is provided, the strut running between the auxiliary frame of the front axle and one of the two lateral sills. This makes it possible in particular to increase the natural frequency of a vehicle front end by structurally simple and also cost-effective measures. | 05-13-2010 |
20100107800 | SHIFTING DEVICE FOR AN AUTOMATIC TRANSMISSION - A shifting device for an automatic transmission including a locking mechanism which can be moved at least between a locked state and a released state, comprises a release button for changing the state of the locking mechanism, prevents the gear-shift lever from being moved at least into the Park and Reverse positions and at least out of the Park position in a locked state, and allows the gear-shift lever to be moved at least between the positions Park, Reverse, Neutral, and Drive in a release state. The locking mechanism can be converted to a partially released state, in which the gear-shift lever can be moved into and out of the Reverse position, whereas the movement of the gear-shift lever into the Park position remains blocked. | 05-06-2010 |
