    摘要： Solenoid valves for controlling the gas flow to burners are controlled by an electronic microprocessor card by means of pulse-width modulated signals. The electronic card can receive signals from a timer to be set by the user, and from means by which the user selects the heat output of the burners. The first of said means to be operated by the user after setting the time makes the relative burner dependent on the timer. When the two data (time and heat output) have been set, the card extinguishes the flame of the dependent burner when the set time has expired.

    摘要： The method provides for applying to the solenoid valve, during its movement of closure by the action of a spring, a voltage signal the purpose of which is to brake this closure movement. The circuit comprises a static switch connected between the coil of the solenoid valve and earth, and an intermediate tap between these two components from which a voltage signal is withdrawn and is transformed by a microcontroller into a control signal for the static switch, such as to apply the braking signal to the solenoid valve.

    摘要： A device for sensing the presence of cooking utensils on a cooking hob comprising at least one heat source. The device includes an electrically conductive coil turn fed by the signal generated by an oscillator. The oscillator is preferably a voltage-controlled oscillator generating square wave signals. The coil turn operates, when utensil sensing occurs, to modify the cut-off frequency of a low pass filter (L/R) fed by said oscillator (VCO).
