Abstract: A transducer converts energy coming from an energy source into an electrical signal for storage as electrical energy on a first storage element. A switch is selectively actuated to pass electrical energy from the first storage element to a second storage element. The selective actuation of the switch is driven by sensing electrical energy stored in the second storage element. The switch is closed when electrical energy in the second storage element is sensed to fall below a first threshold. The switch is opened when electrical energy in the second storage element is sensed to rise above a second threshold.

Abstract: A switching controller of a poly-phase electric motor may generate, in a fully digital manner, a replica of the phase current and/or of the phase (star) voltage of one or more windings of the motor. The switching controller may use digital signals already available for driving the motor to reconstruct a replica of the phase current or the phase voltage, and thereby avoid the need for dedicated analog components for phase current or phase voltage determination.

Abstract: A method for the automatic design of an electronic circuit includes operations for evaluation of the thermal effects in the electronic circuit. The method generates a layout of the electronic circuit. Abstract data at the substrate level associated to the layout of the electronic circuit is then generated. A grid of partitioning is generated with respect to a view regarding the aforesaid abstract into meshes and nodes. The grid is applied to the substrate. On the basis of the grid (TG), a list of nodes or netlist representing a thermal network that represents the thermal behavior of the substrate or of its portions or elements is extracted. The netlist is useful in simulation operations, in particular of a SPICE type, for making an evaluation of thermal effects in the electronic circuit.

Abstract: Producing different ionic liquids industrially currently requires either operating separate plants or continually refitting existing plants. While this is not laborious, it is often not economical either. The problem the present invention addresses is that of describing a method and an industrial process by which different ionic liquids can be produced almost synchronously in a unitary production sequence. This is done either by using a chemical intermediate both relatively simple to prepare and readily convertible into multiple products, or by preparing the desired products in the same industrial process by direct synthesis from the appropriate starting materials. The method described here allows the synthesis of different ionic liquids in excellent yields and grades in a unitary production operation.

Abstract: Errors induced by noise pulses in digital electronic circuits clocked with a clock signal are detected by providing at least one additional clock signal offset in time with respect to the clock signal by a given interval, and performing for at least one component of the circuit a comparison of correspondence between two versions of one and the same signal. The comparison is clocked by the additional clock signal and the absence of correspondence between the two versions of said signal identifies an error induced in the circuit by a noise pulse.

Abstract: A semiconductor device having a circuit that selectively adjusts an impedance of an output buffer. A calibration operation can be performed automatically without issuing a calibration command from a controller. Because a calibration operation to a memory is performed in response to an auto refresh command having been issued for a predetermined number of times, a periodic calibration operation can be secured, and a read operation or a write operation is not requested from a controller during a calibration operation. A start-up circuit activates the calibration circuit when a refresh counter indicates a predetermined value, and prohibits a refresh operation in response to the auto refresh command when the calibration circuit is activated. A temperature detecting circuit may be used to change the frequency of performing a calibration operation.
