| 20090013802 | PRESSURE SENSING MAT - A generally flexible pressure sensing mat for a vehicle seat includes a first carrier foil and a second carrier foil arranged at a certain distance from each other by means of a spacer. The mat includes a plurality of cells, each cell being defined by a respective opening of the spacer. In each cell, at least two electrodes are arranged between the first and second carrier foils and, in response to pressure acting on the pressure sensing mat at a cell, the first and second carrier foils are pressed together against the reaction force of the carrier foils thereby causing variation of an electrical resistance between the at least two electrodes of the cell. The pressure sensing mat includes at least one rigidifying element, the least one rigidifying element being associated to an individual cell for locally reducing flexibility of the pressure sensing mat at the individual cell. | 01-15-2009 |

| 20090250593 | SAFETY SYSTEM FOR A VEHICLE WITH OPTICAL SIGNAL TRANSMISSION - A safety system for a vehicle is provided, which comprises signalling means associated with a seat of the vehicle for emitting an optically detectable signal carrying information related to the seat and detecting means for remotely detecting the optically detectable signal and for providing a corresponding signal to a control unit. | 10-08-2009 |
| 20100295563 | METHOD AND SYSTEM FOR DETECTING AN OCCUPANT IN A VEHICLE SEAT - An occupant detection system comprises an electrode arrangement for placement into a seat of an automotive vehicle and an evaluation circuit operatively connected to the electrode arrangement. The latter includes a first electrode for emitting an electric field into a detection region above the vehicle seat, a second electrode and an electric insulator layer sandwiched between the first and second electrodes. When the electrode arrangement is in place in the seat, the first electrode forms with vehicle ground a first capacitor having a first capacitance, which is influenceable by an occupying item in the detection region through interaction of the occupying item with the electric field, the first electrode forms with the second electrode a second capacitor having a second capacitance and the second electrode forms with at least one of vehicle ground and a third electrode a third capacitor having a third capacitance. As a first indicator of the seat occupancy state, a measure of the first capacitance is determined while the first electrode is caused to emit an electric field into said detection region and the second electrode is operated as a driven shield for the first electrode. The fluctuations of at least one of the first, second and third capacitances are measured and the frequency spectrum of the measured fluctuations is analysed, which yields a second indicator of the occupancy state. The derivation of the occupancy state of the seat is then based on both the first indicator and the second indicator. | 11-25-2010 |
