Abstract: A method for detecting the position of a piston of a piston cylinder is provided. A microwave transmit signal is emitted in the direction of the piston and microwaves reflected from the piston are detected. The transmit signal is a modulated signal with a base frequency sinusoidally modulated at a modulation frequency. An evaluation of the phase between transmit signals and receive signals is performed. A phase determination at the baseband and a simultaneous phase determination at at least one sideband are also performed. The phase determination at the baseband is used for fine determination of the piston position and the phase determination at the at least one sideband is used for coarse determination of the piston position. Bandpass filtering on receive signals and evaluation transmit signals is performed with respect to the base frequency or an intermediate frequency. Bandpass filtering is performed with respect to the modulation frequency.

Abstract: A device for detecting a twist angle and/or a torque of a shaft occurring on the shaft and methods for operating the device uses at least one first encoder and at least one second encoder at a predefined spacing therefrom. Each encoder influences at least one coil parameter, is associated with at least a part of the circumference of the shaft, and has at least one track having at least one period per revolution of the shaft. At least first and second inductive sensors scan the first and second encoders, respectively. Each inductive sensor provides a respective sensor signal reflecting at least one measure for the rotational angle of the shaft within the period, and a difference ascertainment unit ascertains and provides the twist angle of the shaft as an angle difference of the two rotational angles detected by the inductive sensors.
