摘要： Disclosed are a method and a device for more rapidly switching inductive fuel injection valves. According to the invention, the magnetic retaining forces generated by remanence in a bistable valve comprising an opening and closing coil or by eddy currents in a standard valve comprising an opening coil and a closing spring are eliminated with the aid of a negative current that flows through the coil in a direction running counter to the direction of the operating current. Additionally, the magnetic yoke and armature that are used are made of materials having different conductivities in order to be able to close the valve even more quickly.

摘要： A linear exhaust-gas probe has a measuring cell for measuring a gas concentration in a measuring chamber by determining a measuring-cell voltage, and a pump cell for pumping gas by way of a pump current. A circuit configuration for operating the prove has a comparator circuit for comparing the measuring-cell voltage with a measuring-cell setpoint voltage and for providing a corresponding analog deviation signal. A pump current source provides the pump current. The source is controlled by the deviation signal using a control circuit for the approximation of the measuring cell voltage to the measuring cell setpoint voltage. In order to reliably limit the pump voltage with no significant detrimental effect on the operation, the circuit configuration further has a second comparator circuit for comparing the pump voltage with a predefined threshold voltage and for providing a corresponding binary switching signal; and a counter coupling path between the output of the pump current source and the control circuit. The path is enabled when the voltage threshold is crossed.

摘要： A low-frequency PWM-modulated signal and a high-frequency, unmodulated signal for generating a high-frequency PWM-modulated signal is employed directly for driving an output stage of a device for noise suppression. The low-frequency signal and the high-frequency signal is advantageously provided by a microcontroller which already has an AD converter on the input side. The microcontroller furthermore already makes a PWM output signal with a high bit width available which has the high resolution necessary for driving the loudspeaker.

摘要： A valve has a valve piston, at least one coil and at least one magnetized component. An induction voltage is induced in the at least one coil, by a movement of the valve piston in the valve through a magnetic field produced by the magnetized component. A reference point is acquired, which is representative of a start of a current activation cycle of the valve. In the current activation cycle a point is determined as a function of a characteristic pattern of the induction voltage, which is representative of an end of a movement process of the valve piston in the valve. A current response time is determined as a function of the point and the reference point. At least one error condition is determined as a function of the response time. An error is identified, when the at least one error condition is satisfied.

摘要： A bi-directional switch has at least one first controllable semiconductor component with a first input contact, a first output contact, and a first control contact, and at least one second controllable semiconductor component with a second input contact, a second output contact, and a second control contact. The first input contact of the first semiconductor component and the second input contact of the second semiconductor component are interconnected in an electrically conducting manner, and the first control contact of the first semiconductor component and the second control contact of the second semiconductor component are interconnected in an electrically conducting manner while the first output contact of the first semiconductor component and the second output contact of the second semiconductor component are electrically insulated from each other. The semiconductor components are disposed on a common substrate that is provided with an electrically conducting coating. At least one of said semiconductor components of the switch is arranged on the electrically conducting coating in such a way that a joint contact area corresponding to at least 60 percent of the surface of the contact, which faces the coating, is created between the coating and said surface of the contact, which faces the coating. Said arrangement makes it possible to create a low-impedance, low-inductive bi-directional switch.

摘要： The device comprises a voltage divider (Rv1, Rv2) to whose two terminals the oscillator signal with a phase position that is mutually opposed is supplied until, in the instance of a switched-on probe heating, the voltage (VRpvs) that is proportional to the probe internal resistance (Rpvs) falls below a predetermined set value (set), whereby, at this point in time, the output signal of the oscillator (SZ) is supplied to both terminals of the voltage divider (Rv1, Rv2) with the same phase position (area 1) thus effecting an amplitude change-over (amplitude amplification).

摘要： An injector driver module includes a first converter and a second converter connected between a power supply and the load. The first converter generates a first voltage output and the second converter generates a second voltage output from the power supply. Switches control the level of the supply voltage so that the voltage applied to the load can be varied depending on an operational phase of the driver. Control over the current through the load can be therefore be conducted via pulse width modulation at lower voltage levels, thereby lengthening the switching time during modulation, reducing power losses, and reducing EMI emissions.

摘要： A voltage monitoring device for monitoring two different supply voltages to be received by an electronic component. The monitoring device has a ratiometrically operating analog/digital converter, whose reference input is supplied with the larger supply voltage and whose measurement input is supplied with the smaller supply voltage. An output signal of the analog/digital converter is supplied to a window comparator in which the output signal is compared with predetermined limit values. A reset signal for the electronic component is produced if the output signal is greater than the upper limit value or less than the lower limit value.
