Disclosed is a method for obtaining properties using an indentation. The method includes an initial value calculating step, a reference value calculating step, a pre-set value setting step and a checking step. So the method obtains properties only using an indentation without additional experiments

Disclosed is a camshaft or crankshaft sensor including a toothed target, a measuring cell adapted to supply a raw signal and a processor module having two modes of operation: 1) a measurement mode in which the processor module is adapted to supply an output port of the sensor a measurement signal representing the times of passage of the teeth of the target at the level of the measuring cell; and 2) a diagnostic mode in which the processor module is adapted to supply at the output port of the sensor a diagnostic signal different from the measurement signal and representing the amplitude of the raw signal. Also disclosed is a method and a module for diagnosing such a sensor.

A method for offset calibration of a rotation rate sensor signal of a rotation rate sensor. In a first step, an ascertainment is made that the rotation rate sensor is in an idle state. In a second step, after the first step, a filter parameter is determined as a function of the measured rotation rate sensor values, measured in the idle state, of the rotation rate sensor. In a third step, after the second step, a filtered measured rotation rate sensor value is determined with the aid of the filter parameter. An offset is determined with the aid of the filtered measured rotation rate sensor value.

A vehicle detection method includes acquiring a first output and a second output, detecting peaks and detection times from the first output, detecting peaks and detection times from the second output, extracting first peaks for one vehicle, extracting second peaks for the one vehicle, comparing the number n of the first peaks with the number m of the second peaks, and when the number n and the number m are different from each other, creating nCm or mCn combinations of the peaks, calculating differences between detection times of the plurality of first peaks and detection times of the plurality of second peaks in order of the detection times for each of the combinations, calculating variance values of the differences, and selecting a combination of the peaks having the smallest variance value.

A device for contactlessly determining a position of a pedal in a vehicle, having at least a magnet and a sensor, wherein the magnet produces a magnetic field that varies with the position of the pedal and detected by the sensor. The sensor has an output for providing at least one sensor signal. A first and a second position range are defined, wherein each position range includes positions of the magnet with respect to the sensor. The processor generates an output signal from the at least one sensor signal. The output signal takes on values that are unambiguously associated with a position of the magnet relative to the sensor in the first position range, and takes on a constant value that is independent of the position of the magnet relative to the sensor in the second position range.

A thickness measuring device of the present invention includes a supporter which supports a specimen, an emission unit which emits an electromagnetic wave in a direction toward the specimen, a chamber which surrounds the specimen, a receiving unit which receives an electromagnetic wave output in a direction in which the chamber is positioned, and a control unit which receives a signal from the receiving unit and calculates a thickness of the specimen.
