Patent number: 8656366Abstract: A microprogrammable electronic device has a first code memory storing instructions, and is configured to execute each instruction in the first code memory at a respective instruction cycle. The system comprises binary code generating means, and a tracing device. The binary code generating means form part of the device, and are configured to generate and output on a single pin of the device binary codes, each of which indicates a corresponding execution-related event, is generated and outputted at a corresponding instruction cycle, and has N bits, where N is an integer >=2. The tracing device is coupled with the single pin to receive the binary codes, and has a second code memory in which the instructions are stored. The tracing device is configured to trace instructions executed by the device, on the basis of the received binary codes and of the instructions stored in the second code memory.Type: GrantFiled: August 2, 2010Date of Patent: February 18, 2014Assignee: C.R.F.

Patent number: 8527743Abstract: A microprogrammable electronic device comprises a code memory storing a plurality of instructions. At least one instruction, when executed by the device, causes the device to enter into a wait state associated with a plurality of predefined wait state exit conditions. The device is configured to load into an electronic table each condition together with a corresponding code memory address of an instruction to be executed when the condition occurs; to execute, when is in the wait state, a wait instruction stored in the code memory and which, when executed, is such as to cause the device to check simultaneously the conditions loaded into said electronic table to detect if condition occurs; and, if a condition occurs, to exit from said wait state and to execute the instruction stored in the code memory at the code memory address loaded into the electronic table together with the condition that occurred.Type: GrantFiled: August 2, 2010Date of Patent: September 3, 2013Assignee: C.R.F.

Patent number: 8166932Abstract: The movable element of a solenoid valve is displaced by means of application to the solenoid of alternating phases at constant voltage and at zero voltage, so as to give rise to an alternation of phases of charging and discharging of the solenoid (switching), corresponding to increases and decreases of current around a substantially constant current value. The alternating phases at constant voltage and at zero voltage are controlled so that the phase at constant voltage is maintained for a pre-set time and the phase at zero voltage is terminated when the decreasing current reaches a pre-set value. Alternatively, it is possible to envisage that the phase at constant voltage will be terminated when the increasing current reaches a pre-set value and the phase at zero voltage is maintained for a pre-set time, or else again that both the phase at constant voltage and the phase at zero voltage will be terminated when the increasing current or decreasing current reaches a pre-set value.Type: GrantFiled: November 18, 2008Date of Patent: May 1, 2012Assignee: C.R.F.

Patent number: 8132561Abstract: Provided in a gas-feed system, in particular a system for supplying methane or hydrogen to an internal-combustion engine, is an electronic pressure-reducer or pressure-regulator unit, integrated in which are both a pressure-reducing valve for reducing the pressure of the gas coming from the fuel tank to a value suitable for supplying a distribution manifold or rail and a modulating solenoid valve that functions as modulator of the degree of pressure reduction performed by the pressure-reducing valve. Likewise made in the body of said unit are passages that provide the communications of said valves with one another and of each of said valves with the inlet and the outlet for the gas in said unit. Furthermore, the unit incorporates an electronic control module for controlling the modulating solenoid valve.Type: GrantFiled: October 31, 2007Date of Patent: March 13, 2012Assignee: METATRON S.r.l.Inventors: Filippo Audisio, Massimiliano Bagnato, Riccardo Groppo, Alberto Manzone, Damiano Micelli, Paolo Reggio
