摘要:
Specific shift positions of an electrically actuated vehicle transmission, such as first to fifth, neutral and reverse gears, are detected by monitoring one or more characteristic electrical variables, e.g., actuator currents, during a shift movement of the transmission and by correlating increased or decreased levels of current with the arrival at or passage through the specific shift positions.

摘要:
A motor vehicle transmission is shiftable in a track pattern with a selector track and shift tracks. A shifter element moves along the tracks when the transmission is shifted from one gear ratio to another. The shifts are directed by a control device sending command signals to an actuator device which, in turn, applies an actuating force to the transmission. A main position-detecting device detects the position of the shifter element relative to the selector track and shift tracks, and a redundant position-detecting device performs an additional, redundant determination of the shifter-element position.

摘要:
The present invention is related to a method and apparatus for cleaning a substrate, in particular a semiconductor substrate such as a silicon wafer. The substrate is placed in a tank containing a cleaning liquid, at an angle with respect to acoustic waves produced in said liquid. The angle corresponds to the angle of transmission, i.e. the angle at which waves are not reflected off the substrate surface. A damping material is provided in the tank, arranged to absorb substantially all waves thus transmitted through the substrate. A significant improvement in terms of cleaning efficiency is obtained by the method of the invention.
