Abstract: A camera system comprises a 3D TOF camera for acquiring a camera-perspective range image of a scene and an image processor for processing the range image. The image processor contains a position and orientation calibration routine implemented therein in hardware and/or software, which position and orientation calibration routine, when executed by the image processor, detects one or more planes within a range image acquired by the 3D TOF camera, selects a reference plane among the at least one or more planes detected and computes position and orientation parameters of the 3D TOF camera with respect to the reference plane, such as, e.g., elevation above the reference plane and/or camera roll angle and/or camera pitch angle.

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.

Abstract: An occupant classification system for a vehicle comprises a radio-frequency (RF) transmitter unit, which includes a transmission RF antenna and an RF generator operatively connected to the transmission RF antenna. The RF generator and the transmission RF antenna are configured for generating radio waves at a certain fixed RF frequency in the Very High Frequency (VHF) range or the Ultra High Frequency (UHF) range. During operation of the RF transmitter unit, the generated radio waves propagate from the transmission RF antenna. The occupant classification system further comprises an RF detector for detecting, at the fixed RF frequency, an influence of an occupant on the radio waves propagating from the transmission RF antenna.

Abstract: A child seat presence and/or orientation detection system for detecting, on a vehicle seat, presence and/or orientation of a transponder-equipped child seat includes a loop-shaped transmission antenna for transmitting an electromagnetic excitation field and a loop-shaped reception antenna for receiving an electromagnetic response field emitted by a transponder of a child seat in response to the electromagnetic excitation field; the loop-shaped transmission antenna surrounds a first, the loop-shaped reception antenna a second area; the second area includes an overlap area with the first area; the second area also includes a non-overlap area with the first area, i.e. an area which is part of the second area but does not overlap with the first area, such that the magnetic flux caused by the loop-shaped transmission antenna in the non-overlap area is of opposite sign with respect to the magnetic flux caused by the loop-shaped transmission antenna in the overlap area.

Abstract: A method for fitting a sensor onto a seat cushion is disclosed, which is specifically suitable for the assembly of a seat sensor onto a seat cushion, wherein the seat cushion comprises a seating surface having a central region, said central region of said seating surface being at least partially delimited by a groove extending from said seating surface into said seat cushion, and wherein said sensor comprises a first sensor portion to be arranged at least partially at a periphery of said central region. The method comprises the steps of providing a mould (10) for foaming said seat cushion, said mould comprising at least one ridge (14) designed for forming said groove into said seating surface of said seat cushion; arranging said first sensor portion (18) in said mould on said at least one ridge (14), and foaming said seat cushion, thereby integrating at least part of said first sensor (18) portion into said seat cushion.
