  • Method and system for controlling radio frequency power
    Patent number: 8912835
    Abstract: A method for controlling pulsed power that includes measuring a first pulse of power from a power amplifier to obtain data. The method also includes generating a first signal to adjust a second pulse of delivered power, the first signal correlated to the data to minimize a power difference between a power set point and a substantially stable portion of the second pulse. The method also includes generating a second signal to adjust the second pulse of delivered power, the second signal correlated to the data to minimize an amplitude difference between a peak of the second pulse and the substantially stable portion of the second pulse.

  • Housingless washer
    Publication number: 20060180181
    Abstract: An industrial parts washer includes a stand adapted to support a part, a chamber selectively moveable from a first position clear of the part to a second position engaging the stand where the chamber forms a closed volume encapsulating the part. A nozzle is positioned within the chamber to supply pressurized fluid for cleaning the part. The industrial parts washer may include a washing station positioned adjacent a drying station where each of the washing and drying stations include chambers selectively moveable to enclose the part.
