    摘要: A method for measuring the resistance of a load, preferably the firing pellet of an airbag, that is connected on the secondary side of a rotary transformer, in which the resistance measurement is largely unaffected by the magnetic coupling between the windings of the transformer. According to this method, the capacitor is partially discharged twice in succession. During the first partial discharge, the capacitor is discharged continuously, and during the second partial discharge, the capacitor is discharged in steps. After the two partial discharges, the residual charge voltages at the capacitor are measured and the difference between the two charge voltages is obtained. This difference is an indication of the resistance of the load connected on the secondary side of the transformer.

    摘要: A MOS field-effect transistor (T2) is provided in conjunction with transistors (T1 and T3) as polarity reversal protection in an electrical circuit arrangement (1). Polarity reversal protection of this type is realized by the drain-source path of the transistor (T2). Transistors (T1 and T3) form a comparator. If the drain-source voltage of the transistor (T2) becomes negative then the transistor (T3) switches on. This, in turn has the effect of switching off the transistor (T2) thereby providing polarity reversal protection. The electronic circuit arrangement (1) configured according to the invention can advantageously be used in an airbag system (10).

    摘要: 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.

    摘要: 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.

    摘要: A control unit in a vehicle is provided in which power is supplied via a converter that provides an electrical isolation. For the data exchange with external components and other components in the control unit that are not electrically isolated, the component isolated by this electrical isolation is additionally connected to a coupling element that likewise provides an electrical isolation.
