Abstract: A method for driving a power transistor includes comparing a measurement signal that is representative of a load current to a comparator threshold that corresponds to an overcurrent threshold; generating a first fault signal when the measurement signal exceeds the comparator threshold for a first time interval; generating a second fault signal when the measurement signal exceeds the comparator threshold for a second time interval that is greater than the first time interval; regulating a control voltage provided to the control terminal of the transistor to turn off the transistor in response to the second fault signal; and in response to the first fault signal, adjusting the control voltage to an adjusted voltage level in order to limit the load current to a reduced current level that is preconfigured to be greater than the overcurrent threshold. The adjusted voltage level is sufficient to maintain the power transistor in an on-state.

Abstract: The present invention refers to an interchangeable device comprising: a high-pressure pump unit (16002), a water intake (16003), and a lance (16005), characterized by a coupling system comprising: a shaped shaft (16001)-shaped hub (16007) coupling, an anti-rotation positioning element (16008), and a locking clamp (16009), wherein the coupling system allows a power generator of varying type (16006) to be coupled, rendering the device a high-pressure washer and/or a high-pressure sprayer.

Abstract: The present invention refers to a device for the discharge of a pressurised liquid comprising: a liquid intake section (2400), a liquid discharge lance (2300), a pump (2200), which can be connected to a motor (2100), the pump having an inlet connected to the intake section and an outlet connected to the discharge lance, where the discharge lance and the pump are connected by a connection (2800, 2801, 2802, 2803, 2804), with at most three rotational degrees of freedom and/or one translational degree of freedom.

Abstract: Space-heating apparatus, comprising a radiator with a fluid to transfer the heat and an electric heating element, general means for adjusting and controlling grouped together in two separate assemblies, in which a first assembly comprises: control elements that can be operated from the outside and selectively set by the user, a transmission means for modulating/coding signals that represent the settings in said control elements, and for transmitting said signals to a second assembly that comprises: adjusting elements and respective control means, relating at the electric current supplied to said heating element, and means for receiving and for demodulating the signals coming from said transmission means; said first assembly is arranged on the upper part of the apparatus, and said transmission means and receiving means transmit by radio-frequency or infrared signals.
