Abstract: In a system having a control unit for triggering a restraint system for vehicles, and having a status acquisition device, such as a seat occupation device, from which a data record describing the presence or the non-presence of the condition is transmitted to the control device, upon a defined stimulation signal from the control unit to the status acquisition device the latter transmits a second data record to the control unit, which corresponds to the type characteristics and the type data. Thereby, type data are able to be recorded even in the case of a status acquisition device installed in an obstructed way in a motor vehicle.

Abstract: Proposed is a method for programming and/or testing for the correct functioning of an electronic circuit, and a corresponding device, which is used to efficiently program and test electronic circuits combined on a wafer, prior to their separation. For this purpose, a bus allowing the individual electronic circuits to be sequentially tested is positioned on the wafer. Each electronic circuit is assigned an address for the bus, using a hardware code. The address is deactivated after completion of the functionality and testing method.

Abstract: A method and device for child seat recognition in a vehicle involving use of radio signals to recognize a child seat. The child seat includes a passive transponder. The radio signal is sent back by the child seat and is then sampled by a device in the vehicle, the computing time between the sampled values is used for the management of other tasks. After the termination of the sampling, the evaluation occurs. This is controlled using interrupts.

Abstract: A method for adjusting the sensor cells of a seat mat to a mechanical stress caused by the installation of the seat mat in a vehicle seat, a diagnostic tester being connected to a control unit at the seat mat, and the diagnostic tester reads out the sensor values of the seat mat and compares them to setpoint values, in order then to transmit back correcting values to the control unit, which the control unit uses in further operation for calibrating the sensor values.

Abstract: A method for occupant classification in a vehicle is used to extract a plurality of features from a seat profile and to assign a weight estimate to each of these features. The occupant weight and a measure of quality are determined from the different weight estimates. The measure of quality determines whether the occupant weight continues to be used as the occupant classification. The weight estimation for the feature in question is carried out via a stored function. The occupant classification can be used for a restraint system. The ischial tuberosity distance and/or the seat profile size can be used as the features.

Abstract: A method for adjusting the sensor cells of a seat mat (3) to a mechanical stress caused by the installation of the seat mat (3) in a vehicle seat is proposed, a diagnostic tester being connected to a control unit at the seat mat, and the diagnostic tester reads out the sensor values of the seat mat and compares them to setpoint values, in order then to transmit back correcting values to the control unit, which the control unit uses in further operation for calibrating the sensor values.

Abstract: To sense the occupancy status of the seat surface of a seat, in particular in a vehicle, an electrically conductive foamed plastic is used, at least in sections, in the seat surface, and a signal corresponding to the resistance value between a top-side and a bottom-side electrode is utilized for discrimination purposes to determine whether the seat is occupied or not. An array of a plurality of parallel strips or a matrix of patches of the conductive foamed plastic permits a more thorough discrimination in terms of the occupying object or the occupying person.

Abstract: A method and a device are for evaluating sensor signals from a seat mat in a vehicle seat, the signals functioning to characterize the sensors in the seat mat as active and inactive. In this manner, a linear evaluation method is performed to make possible a weight classification of passengers situated on the vehicle seat. For this purpose, a seat profile is generated using the active and inactive sensors.
