Abstract: The invention relates to a current sensor including at least one resistance element on which voltage (UGS) for measuring the current (iMEAS) flowing through the resistance element is detected. The resistance element is designed so that at least, within a defined measurement range of the current sensor, the electric resistance of the resistance element reduces when the current (iMEAS) flowing through the resistance element increases.

Abstract: A device and a method trigger a vehicle occupant protection device of a motor vehicle. The device has a plurality of sensors that are disposed at a first location within the motor vehicle, and an evaluation device that is disposed at a second location within the passenger car. The plurality of signals that are assigned to the plurality of sensors are transmitted from the first location to the evaluation device via a first and a second transmission link of the device.

Abstract: The invention relates to a device that comprises a plurality of energy stores and a driver circuit. Said driver circuit is supplied by at least two of the energy stores via a selecting circuit in such a manner that the driver circuit is always supplied by the energy store that has the highest voltage as compared to the remaining energy stores.

Abstract: The invention relates to a method and a device for controlling occupant protection means in a vehicle. According to said method, a first crash variable (AAA), derived from the absolute value for the crash signal of a crash sensor, preferably from the acceleration signal of an acceleration sensor, is compared with a first firing threshold (th1a, th1b, th1c). In addition, a second crash variable (wj, wv, ws), derived in a different manner from the crash signal (a) of the crash sensor (1) is compared with a second firing threshold (th2a, th2b, th2c). The occupant protection means is only fired if the first crash variable (AAA) exceeds the first firing threshold value (th1a, th1b, th1c) and simultaneously the second crash variable (wj, wv, ws) exceeds the second firing threshold (th2a, th2b, th2c).

Abstract: The invention relates to a control unit for activating an occupant protection means in a motor vehicle and to a method for monitoring the proper functioning of a control unit preferably of this type. To this end, the control unit comprises a first and a second arithmetic unit (R1, R2) as well as an activating unit (AE). A number of logical AND gates (AND1, AND2; AND3) are connected on the input side to the clock signals (clk1, clk2, clk3) of the arithmetic units (R1, R2) respectively assigned thereto or to the activating unit (AE). The signal output of each logical AND gate (AND1, AND2; AND3) is fed to a respectively assigned pulse count comparator unit (PZVE1, PZVE2) whose respective signal output is, in turn, connected to an input of a respectively assigned resetter (RES1, RES2).
