    Abstract: Described herein is a system for controlling a solenoid valve, which includes a driving circuit for driving a solenoid of the solenoid valve and a control unit for controlling the driving circuit. The control unit is configured for generating in the solenoid, during operation of the solenoid valve: first current signal for moving the open/close element from a first position to a second position, which is generated by the external supply network, to which the solenoid is connected; and second current signal, which is generated exclusively as a result of residual magnetism in the magnetic element of the solenoid valve and is activated when the open/close element is still in the aforesaid second position.

    Abstract: An internal-combustion engine includes a three-way, three-position control valve with an inlet communicating with a pressurized-fluid chamber and with a hydraulic actuator of an intake valve, and two outlets communicating, respectively, with the actuator of the other intake valve and with said exhaust channel. The control valve has a first position, in which the inlet communicates with both of the outlets, a second position, in which the inlet communicates only with the outlet connected to the actuator of an intake valve and does not communicate, with the outlet connected to the exhaust channel, and a third position, in which the inlet does not communicate with the two outlets. The control valve has an electric actuator supplied only at three different values of electric current to bring the valve into the three positions.

    Abstract: An internal-combustion engine includes a system for variable actuation of intake valves, including a control valve for each cylinder, which controls communication of a pressurized-fluid chamber with a discharge channel. The control valve has at least three different positions, namely, a first completely open position, a second partially open position, and a third completely closed position. Electronic control means are programmed for keeping the control valve in its closed position in operating stages in which the intake valve must remain coupled to the respective cam and for bringing the control valve from its completely closed position to its partially open position or to its completely open position in operating stages in which the intake valve must be uncoupled from the respective cam, selection between the first position and said second position of the control valve being made as a function of one or more operating parameters of the engine.

    Abstract: A method for locating a tool in a work space via ultrasound includes associating an ultrasound transmitter to a tool and calculating a position of the tool on the basis of determination of the position of the transmitter. At least three ultrasound receivers for receiving ultrasound signals from the transmitter are set in positions relative to the work space. A calculation of a position of the transmitter includes using a trilateration procedure that includes a change of reference of the positions of the receivers and is carried out to reference them in a second simplified reference system. An unknown point in the second simplified reference system is obtained. A rototranslation of the position of the unknown point obtained from the second simplified reference system is carried out into a first reference system, and a corresponding rototranslation matrix is calculated such that the unknown point is used as position of the transmitter.
