    摘要: An air bag system is provided for use in a motor vehicle. The air bag system includes at least one air bag module. A multiple level gas generation source is coupled to the air bag module for generating a selected gas generation level applied to the air bag module. An electronic control unit controls the operation of multiple level gas generation source. At least one temperature sensor is coupled to the electronic control unit for sensing ambient temperature. At least one seat belt sensor is coupled to the electronic control unit for sensing seat belt usage. An acceleration sensor is coupled to the electronic control unit for sensing deceleration during a crash. The electronic control unit is responsive to a combination of sensed inputs from the temperature sensor, the seat belt sensor and the acceleration sensor for determining both an optimum gas generation level and inflation sequence times for controlling the multiple level gas generation source.

    摘要: To facilitate assembly and provide for high-level output from a deceleration sensor which provides, inherently, only very low level output, an evaluation circuit, such as an amplifier structure, is connected immediately adjacent the deceleration sensor on a common metal plate, interconnected thereby by bonding wires, the common plate having connecting pins (18) passing therethrough for connection to a standard plug-and-socket connector; the evaluation circuit and the deceleration sensor are enclosed within a common sealed housing, so that both the deceleration sensor (12, 12') as well as the evaluation circuit (16, 17) are sealed against ambient influences, preferably retained within a high-viscosity fluid, such as insulating oil. All elements can be located on one side of the housing, in which a standard T5 transistor housing is suitable; or the deceleration sensor may be located on the other side of the metal plate (10) from the evaluation circuit, in which case a plastic housing can be used, only the deceleration sensor being secured to the metal plate by a metal housing cap, sealed to the metal plate.

    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: 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.
