摘要： A driver supplying a total current to a load has a plurality (n) of driver stages (ST1 . . . STn). One stage is a master stage. Each driver stage has a switching device (Q) and an inductor (L) connected in series between the switching device and the output of the driver stage. The switching devices are turned ON in sequence with one another, during a cycle time (Tc) which is determined by sensing current through the inductor (L1) in the master stage. When the switching device is turned ON current through the inductor rises, when the inductor current reaches the value of a demanded current the switch is turned OFF, and after the switch is turned OFF the inductor continues to supply (output) current to the load with a current which ramps down. A rectifying device (D) connected between the inductor and the supply line allows current to continue to flow in the inductor and be supplied to the load after the switch is turned OFF.

摘要： A capacitor is connected to the output of a multiphase power converter, and a current-driven device (e.g., LED or laser diode) is also connected to the power converter output. A solid state switch (FET or IGBT) is connected in series with the current-driven device. Means are provided for sensing current through the current-driven device. An error amplifier compares sensed current through the current-driven device with a current level demand signal and controls the output of the power converter. Means are provided for turning the switch on and off and may be (i) a fast comparator receiving a voltage reference signal at one input and the current level demand signal at another input, and outputting the switch on/off signal to the switch or (ii) an externally-generated logic signal provided directly to the switch.

摘要： A paint formulation which contains specific enzymes which remain inactive in an applied surface coating of the paint formulation until specifically activated by a subsequently-applied applicator solution to facilitate removal of the surface coating. When the applicator is applied to the surface coating, the enzymes catalyse the hydrolysis of the binder in the paint or surface coating, e.g. by cleaving the ester bonds in the 1 and 3 positions of the triglyceride molecules. This allows for easy and rapid removal of the coating without damaging or affecting the underlying surface. The invention is useful either for general purpose paint removal, or for the cleaning up or removal of unwanted graffiti.
