Abstract: Method and station for the construction of a stator winding with rigid bars for a rotary electrical machine; an insulated wire of electrically conductor material and provided on the outside with an insulating layer is unwound from a coil. A final end of the insulated wire is bent in a “U” shape so as to create a bar having two legs connected to one another by a cusp. The insulated wire is transversely cut to separate the rigid bar from the remaining part of the wire; and the bar is inserted into a stator slot of a magnetic core of a stator. The electrical conductivity is measured between the core and the outer surface of the insulated wire by means of a first electrode electrically and permanently connected to the core of the insulated wire and a second electrode, which rubs against the outer surface of the insulated wire.

Abstract: The present invention relates to a solid-state relay including a power semiconductor switch device connected between a first electrical terminal and a second electrical terminal and having a command terminal. An electronic driving block is adapted to generate a command signal applied to the command terminal to switch the at least one semiconductor switch device from a closed/open state to an open/closed state to disconnect/connect the first electrical circuit portion from/to the second portion of the electrical circuit. An electronic block detects a current which crosses the power semiconductor switch device. The electronic detection block includes a first electronic device adapted to generate a first signal indicative of a difference of potential between the first and second terminals generated by the current which crosses a total resistance present between the first and second terminals of the power semiconductor switch device in the closed state. The total resistance comprises the sum of a first resistance associated with the semiconductor switch device in the closed state and of second bonding resistances associated with an electrical connection between one of the conductive terminals and the respective either first or second electrical terminal.

Abstract: A method for recognizing the type of fuel actually used in an internal combustion engine; the recognition method includes the steps of: sensing the intensity of the vibrations generated by the internal combustion engine within a measurement time window; determining the value of at least one synthetic index by processing the intensity of the vibrations generated by the internal combustion engine within the measurement time window; comparing the synthetic index with at least one predetermined comparison quantity; and recognizing the type of fuel actually used as a function of the comparison of the synthetic index to the comparison quantity; and forcedly altering, when detecting the intensity of the vibrations, the engine control with respect to the normal standard engine control, so as to enhance the behavioral differences of the different types of fuel that can be used by the internal combustion engine.

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.
