    摘要： An electronic circuit for correcting at least one digital measurement signal (ΣΔn, ΣΔ1, ΣΔ2) comprising at least one measurement channel having a sigma-delta modulator and a correction circuit. The sigma-delta modulator changes an analog measurement signal into a digital measurement signal in the form of a binary value sequence. The correction circuit corrects the digital measurement signal (ΣΔn, ΣΔ1, ΣΔ2) as a function of at least one correction datum (trim), wherein the correction circuit comprises at least one adding element and at least one multiplexer. The digital measurement signal is corrected in that the correction datum (trim) is weighted by means of the multiplexer and the adding element as a function of the digital measurement signal (ΣΔn, ΣΔ1, ΣΔ2).

    摘要： The invention relates to an electronic motor vehicle control system having at least one valve actuating circuit which controls a load current by means of pulse width modulation. The actuating circuit has at least one electronic current measuring circuit which has at least one measurement path with at least one analog/digital converter. The analog/digital converts an analog measurement signal of the load current into a digital measurement signal of the load current and is actuated or designed in such a way as to carry out a plurality of current measurements per PWM period. The at least one measurement path of the current measurement circuit has a signal conservation circuit which provides the analog measurement signal of the load current substantially unchanged, and independent of the actual load current, for at least a defined hold time (toff->on, ton->off).

    摘要： An illumination source includes a number of light emitting diodes (LEDs) operating at a first wavelength. Light from the LEDs illuminates a phosphor material that generates light at a second wavelength. A reflective polarizer transmits light at the second wavelength in a first polarization state and reflects light at the second wavelength in a second polarization state orthogonal to the first polarization state. The light at the second wavelength reflected by the reflective polarizer is directed back towards the phosphor material without an increase in angular range. In some embodiments the LEDs, having a conformal layer of phosphor material, are attached directly to the first surface of a liquid cooled plate. A liquid coolant contacts a second surface of the plate.

    摘要： A circuit for detecting a defect of electronic components in an electronic control unit includes an output for driving a load (3). A redundant measurement of the current (IL) is executed at the contacts (G, S, D), in particular at the driven contacts (S, D), of one or more semiconductor circuit elements, and an error function of a semiconductor circuit element is detected when the comparison of two current values (IS, ISense1, ISense2) by way of the current flowing through a load (3, 3′) indicates an unequal current distribution. This circuit is of use in electronic brake force or driving dynamics controllers for motor vehicles.
