  • Method and device for detecting incorrect polarity in a signal transducer formed as an inductive sensor
    Patent number: 6727686
    Abstract: A method and a device for detecting mispolarization in a signal transducer is described, with which the output signal of the signal transducer—that has at least one singularity—is converted into a square-wave signal. Intervals between specifiable signal-level changes are monitored in the region of the singularity, or plausibility windows are set, within which specifiable events must occur. If the intervals do not correspond to the expected intervals, or if specifiable events do not occur within the specifiable time windows or plausibility windows, mispolarization is detected. The method for detecting mispolarization is used, for example, in the case of a signal transducer having a plurality of uniform angular points and one reference point, but it is not limited to such transducers.

  • Method and device for driving an electromagnetic consumer
    Patent number: 6097585
    Abstract: A method and device are described for driving an electromagnetic consumer, which includes a movable element. This element includes a solenoid-operated valve for controlling the metering of fuel into an internal combustion engine. A switching instant is determined within a timing window. Within the timing window, the voltage being applied to the consumer is able to be controlled to an adaptable setpoint value in open and/or closed loop.
