Abstract: Method to determine an opening time of an electromagnetic fuel injector; the electromagnetic fuel injector is controlled using a series of progressively increasing energization times of the electromagnetic actuator; for each control of the electromagnetic injector, the presence or the absence of a closing of the injection valve is detected; the opening time is identified, which is equal to an intermediate value between the last energization time of the electromagnetic actuator for which the absence of a closing of the injection valve was determined and the first energization time of the electromagnetic actuator for which the presence of a closing of the injection valve was determined.

Abstract: A vehicle instrument cluster including a monochromatic display having a matrix of pixels which can be independently controlled by a control unit to inhibit or to allow the passage of light. The instrument cluster has a back-lighting device that emits at least a monochromatic light beam toward a rear surface of the display and through a filter, which is light-permeable and is provided with a coloured graphic representation whose contours have a resolution higher than the one of the display.

Abstract: Described herein is an apparatus for active control of the sound of the engine of a land vehicle, which comprises a device for detecting a fundamental frequency of the sound of the engine, and comprises a generator of signals representing sound waves that have spectral characteristics that depend upon the aforesaid fundamental frequency. The apparatus comprises a modulator, which includes a module that applies a modulation to said waveforms so as to control a value of roughness or fluctuation strength of an audio signal for driving an actuator, which generates an engine noise.

Abstract: A control circuit for a single-cell linear oxygen sensor having a first and a second electrical terminals on which a first voltage and respectively a second voltage are present, wherein a cell current between the first and second electrical terminals is indicative of a detected oxygen concentration, and wherein the control circuit generates a biasing voltage between the first and the second electrical terminals with a preset pattern as a function of the cell current. The circuit envisages: a transresistance block, coupled to the second electrical terminal to generate a processed voltage as a function of the cell current and based on the preset pattern; and an adder stage, coupled to the transresistance block and to the second electrical terminal, to perform a sum between the processed voltage and the second voltage, to generate the first voltage for the first electrical terminal of the linear oxygen sensor, so that the biasing voltage has the preset pattern as a function of the cell current.
