A device for monitoring an operation of an inductive element, includes a current-measuring device is switched in series with the inductive element. The device is configured to ascertain a first time-discrete and value-discrete signal, which characterizes a current flowing through the current-measuring device; to ascertain a second time-discrete and value-discrete signal, which characterizes a current flowing through the current-measuring device and has a predefinable time shift in relation to the first signal; and to infer the presence of a shunt from a comparison of the first signal with the second signal. Also described is a method for monitoring the operation of the inductive element.

A method is provided for controlling the current intensity of the electric current flowing through an inductive consumer, the consumer being connected in series to a switching device and a current measuring unit, and in parallel to a free-wheeling element, and the switching device being activated for adjusting the current intensity during a pulse width modulation period. It is provided that a mean load voltage to be set during the pulse width modulation period is determined from an input current intensity with the aid of a first controller, the mean load voltage being set in the pulse width modulation period with the aid of the switching device at the consumer, the mean load voltage or a setpoint load voltage determined with the aid of a second controller from a predefined setpoint current intensity being fed to a model adapted to the consumer, and the input current intensity being ascertained from the difference between the predefined setpoint current intensity and a difference variable between an actual current intensity through the consumer and a model current intensity determined with the aid of the model. A circuit configuration for implementing the method is also provided.

A method for serially transmitting data between a first and a second station is provided, the first station unidirectionally transmitting at least two signals to the second station on two signal paths. In this method, a shift register is provided in each station, the two signal paths of the first station being routed in parallel into a shift register, and the data transmission to the second station being carried out by automatically clocking the shift register from a time base.

Method and device for data transmission

The present invention provides a method and a device for serial transmission of data between a processor module and at least one peripheral element with the aid of a timing signal, a data signal and a selection signal. To reduce the number of lines necessary for the serial data transmission between the processor module and the at least one peripheral element at high data rate, the timing signal may be transmitted via two timing lines between the processor module and the at least one peripheral element, the data signal may be transmitted via two data lines between the processor module and the at least one peripheral element, and the selection signal may be transmitted via the data lines.

A device and a method are described for controlling an electromagnetic user, especially a magnetic valve for influencing the fuel quantity to be injected into an internal combustion engine. At least one switching time of the user is taken into consideration in the control. The at least one switching time is ascertained starting from a current value.

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 threshold 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.

An integrated semiconductor device having a thyristor includes outer npn-transistors, outer pnp-transistors, and an inner npn-transistor. The outer pnp-transistors and the inner npn-transistor are interconnected so as to form a thyristor to allow the inner transistor to be biased into conduction. Furthermore, a current flow takes place via the outer npn-transistors and the inner npn-transistor. The integrated semiconductor device having a thyristor minimizes interference produced in neighboring components.
