Abstract: A method for corrected depth measurement with a time-of-flight camera using amplitude-modulated continuous light. In order to enable an accurate and efficient depth measurement with a time-of-flight camera, the method includes, for each of a plurality of pixels of a sensor array of the camera: acquiring with the camera a raw depth value rm for the pixel; and automatically calculating a ground truth value rt according to: rt=g(rm?cm)+ct, to correct a systematic depth error of the raw depth value rm, wherein cm is a pixel-dependent first offset, g is a pixel-independent first function and ct is a pixel-independent second offset.

Abstract: A pressure-responsive B-surface seat occupancy sensor unit for detecting an occupancy state of a seat comprises a pressure sensor arranged on a base plate. The pressure sensor includes a printed circuit board having a first surface with at least two electrodes and a second surface, with which the PCB is arranged on the base plate, and a membrane element arranged in facing relationship with and spaced from the electrodes so as to deflect under pressure and establish an electrical contact between the electrodes. The base plate includes one or more fixation elements, by means of which the base plate is fixable to the structural frame, the seat cushion and/or the cushion-supporting springs of the seat.
