The disclosure relates to a transmission mechanism with at least two gearwheels that can be brought into form-fitting engagement with one another. One of the gearwheels is designed as a movable gear and, in a disengaged position, is arranged in a freely rotatable manner on a transmission shaft. The other of the gearwheels is designed as a fixed gear and is arranged non-rotatably on a further transmission shaft, the movable gear is connectable non-rotatably to the transmission shaft by a clutch unit and at least one transmission gear can be engaged if a clutch toothing of the clutch unit engages in a form-fitting manner in a toothing of the movable gear in a tooth-on-tooth-gap position. A sensor device detects a rotational speed signal incoming into the other transmission shaft and a rotational speed signal outgoing from the transmission shaft.

Transmission mechanism

A magnetic displacement sensor, where, in order to achieve an improved measurement behavior, magnets are formed in a direction of an x-axis such that a z-component (B) of the flux density has an essentially linear characteristic curve in a region of travel and/or the magnets are formed in a direction of a y-axis such that the z-component (B) is essentially constant in a region of a transversal offset.

Magnetic displacement sensor

A method for monitoring a system controlled by a processor utilizes an integrated monitoring unit independent of the processor but integrated together with the processor in an integrated circuit, as well as a watchdog unit for preventing measures that influence the system. The watchdog unit is cyclically reset by the integrated monitoring unit.

Method for operating a processor-controlled system

An actuator for electromagnetically controlling a valve with a device comprising a magnetic field sensor and a magnetic field transmitter for determining the instantaneous position of a retaining plate, the magnetic field sensor and the magnetic field transmitter being surrounded by magnetic screening.
