Abstract: A lidar sensor system. The lidar sensor system includes a transmission unit having a laser source, a phase modulator for modulating a phase of the light of the laser source, and a transmission optic for emitting the modulated light; a reception unit having a reception optic for receiving light reflected from an object and having an evaluation unit for evaluating the light received by the reception optic; the transmission unit being embodied to emit several transmission sequences of the light; each transmission sequence having a first portion and a second portion; the first portion being an unmodulated constant-phase signal; the second portion being a signal phase-modulated by the phase modulator; and the evaluation unit being embodied to determine at least an absolute value of a Doppler frequency based on the first portion, and to determine a distance to the object based on the Doppler frequency and the second portion.

Abstract: A valve module with a wireless energy-transfer unit. The wireless energy-transfer unit has at least one energy-transmitting unit and at least one energy-receiving unit. The energy-receiving unit is arranged on a valve piston, on a valve spindle, on a valve actuator housing, on a valve housing, or on a valve-closing element. The energy-receiving unit may be connected to a sensor unit located inside the valve actuator housing.
