Abstract: A control unit and a method for triggering passenger protection device for a vehicle are described, a computer having an integrated circuit transmitting a signal and, as a function of this signal, a current source in the integrated circuit outputting a current for charging the capacitors connected to the integrated circuit and situated in the ignition circuit. The charge of these capacitors is output via a third interface using a characterizing measuring signal.

Abstract: A sensor has a transmitter module for transferring data via a line, the sensor receiving power via the line. At a point in time in which the sensor receives a first power level, it transmits the data for a first time interval. A second sensor which is connected to the line in parallel to the first sensor then transmits its data for a second time interval after the first time interval. A timing sequence control system in the two sensors which is triggered by the point in time of reception of the power ensures the subsequent transmission by the first and second sensor.

Abstract: A method for transmitting data from at least one sensor to a control unit is described, a value range, which is available for encoding the data to be transmitted, being divided into three portions. The first portion is used for the sensor values. The second portion is used for status signals and error signals, and the third portion is used for sensor identification data, the three portions being separated from one another and following in succession.

Abstract: A method of data transmission from a sensor to a control unit and a sensor and control unit are described, the sensor transmitting both differential values and absolute values. The differential values are analyzed in the control unit to perform the function provided, and the absolute values are analyzed for the plausibility check of the function.

Abstract: A device for impact sensing is described which detects an impact by a pressure, a normalized signal being supplied to a processor for analyzing the pressure signal. This normalization may occur either in the pressure sensor, by the sensor element itself or by a signal preprocessor, or in the processor.

Abstract: A method for transmitting data from at least one sensor to a control unit via an appropriate two-wire line is described. The method is used to identify any sensor at the control unit and to implement a plurality of logical channels via the appropriate two-wire line. The at least one sensor receives the necessary electrical energy from the control unit via the two-wire line and then transmits the sensor-specific data.
