Abstract: A method for reading out a sensor unit having a first set of nodes and a second set of nodes and a symmetry which allows different configurations of excitation and sensing lead to a same readout. The method includes changing the readout configuration of the sensor unit by exchanging excitation and sensing between the first set of nodes and the second set of nodes, evaluating the similarity or deviation between measurement signals obtained in different readout configurations of the sensor unit, raising an error if the measurement signals differ more from one another than a predetermined value.

A corresponding method is described. The circuit further includes redundancy testing circuitry for evaluating the similarity or deviation between measurement signals obtained in different states of the switching units.

Abstract: A method for compensating range offset of a range sensor located in a predetermined position in a spatial environment and comprising a pixel array adapted for measuring a distance, the spatial environment comprising at least two stationary reference positions located at predetermined reference distances, the method comprising the steps of: a) determining distance values to the reference positions; b) calculating differences between the distance values and the corresponding reference distances; c) determining a range offset value as the maximum of the differences; d) measuring distance values to positions within the spatial environment using the pixel array; e) correcting the measured distance values by subtracting the determined in-situ range offset value from each of the measured distance values.

Abstract: A transmitter and a receiver for transmitting and receiving data via a power supply line comprise a local signal port for respectively receiving and transmitting a serial bit stream and a power line connection port for respectively transmitting a radio frequency signal and receiving the radio frequency signal via the power supply line. The transmitter comprises a modulator unit adapted for encoding the serial bit stream into a baseband signal and generating the radio frequency signal by mixing the baseband signal with a carrier wave so as to redundantly convey the at least one baseband signal in at least four spectral sidebands of the carrier wave. The receiver comprises a demodulator unit adapted for detecting the at least four spectral sidebands of the carrier wave in the radio frequency signal, isolating a baseband signal from the at least four spectral sidebands and decoding the baseband signal into the serial bit stream.
