Abstract: A subscriber station for a bus system and a method for improving the reception quality in the bus system are provided. The subscriber station includes an acquisition device for acquiring a bus state of a bus of the bus system, and a symmetrization device for the symmetrization, on the basis of the result of the acquisition device, of the bit durations and/or of the delay time durations of the rising and falling edge of a bit of signals received from the bus.

Abstract: The invention relates to a device for controlling a multiple spark operation of an internal combustion engine, wherein an ignition transformer can be switched off and back on again for delivering or interrupting an ignition spark energy based on at least one current threshold. The invention proposes that the at least one current threshold be programmable.

Abstract: For achieving a highest possible measuring accuracy of a circuit for measuring the internal resistance of an exhaust-gas sensor, a method and a circuit for measuring the internal resistance R1 (10) of an electrochemical cell (12) are provided for determining the temperature of an exhaust-gas sensor, especially of a motor vehicle. The circuit is provided with the objective to improve the control to a constant temperature to therefore also improve the performance of the exhaust-gas sensor. A measurement current I_Mess (20) is applied to the internal resistance R1 (10) of the electrochemical cell (12) and a resulting first voltage is detected. A switchover to a reference resistor R2 takes place from time to time or at regular time intervals. With a switchover to the reference resistor R2, the resulting second voltage is stored and thereafter is applied as a reference value for the measurement of the internal resistance R1 (10).

Abstract: A two-wire bus system for connecting a plurality of users has at least one damping circuit for damping line resonances in the two-wire bus system with respect to a reference potential. The damping characteristic of the damping circuit is selected such that the damping only becomes operative above a preestablished reference voltage threshold1 value. In this manner, it is achieved that a useful signal is not weakened by the damping circuit, but rather resonance voltages are damped only above the threshold value. It is advantageous if each of the users of the bus system has assigned to it a damping circuit.

Abstract: An electronic circuit in which resistors R.sub.0 . . . R.sub.n+m are coupled in series with fusible cut-outs Q.sub.0 . . . Q.sub.n+m and in which at least one fusible cut-out Q.sub.n+1 . . . Q.sub.n+m is bridged by an additional resistor R.sub.n+1 ' . . . R.sub.n+m '. Each of the fusible cut-outs Q.sub.0 . . . Q.sub.n+m can be blown from a conductive to a non-conductive state. The total conductance Y.sub.total of the electronic circuit can thus be adjusted by targeted blowing of individual ones of the fusible cut-outs Q.sub.0 . . . Q.sub.n+m.
