A system for regulating the output of a high-voltage, high-power DC supply, the system includes a high-voltage DC power supply, a storage capacitor, and at least one non-dissipative regulator having an output voltage range less than an output voltage range of the high-voltage DC power supply. The regulator includes an internal storage capacitance and a control circuit configured to maintain a desired high-voltage output on a load.

A pulsed electric field method for the continuous extraction of oil and lipids from small aquatic plants, the method including providing a continuous flow of a slurry of small aquatic plants. A continuous flow of small aquatic plants is directed to a treatment zone. Pulsed electric fields are applied to the treatment zone to lyse cell walls of the small aquatic plants to enhance extraction of oil and lipids therefrom.

A compact transformer coupled modulator is described. The modulator includes a transformer comprising a primary and a plurality of secondary windings, where each secondary winding has an output terminal. The modulator also includes a plurality of switches, where each switch is associated with a respective secondary winding and has input and output terminals and a control terminal. The control terminal of each switch is in electrical communication with a respective output terminal of the plurality of secondary windings. Each of the plurality of switches is substantially simultaneously switched by an input signal applied to the primary.

A method of coating an article wherein the method includes placing a large number N of non-industrial stock pieces in a vacuum chamber where N is a function of the cost of each stock piece, generating a plasma about the stock pieces, and supplying a current to the stock pieces at a level tailored to sufficiently coat each of the plurality of stock pieces with ion from the plasma and wherein the current level depends on the number N of stock pieces.

A phased array antenna system compensates for the effects of antenna flexure, vibration and movement, and thereby negates these effects by introducing an appropriate phase or time delay into the signals being radiated from and received by the discrete antenna elements comprising the phased array antenna. This compensation eliminates the need for massive rigid back structures to maintain antenna rigidity, which thereby simplifies antenna design.
