摘要： A mechanical scraper with synchronized pulse electrothermal deicing includes a heating element that is coupled to a power supply and that is operable to convert power from the power supply into heating energy. A controller controls the magnitude and duration in which power is applied to the heating element, such that only an interfacial layer of ice at an ice-object interface is disrupted for a sufficient period of time to allow the scraper to move or remove the dislodged ice/snow. A scraper then works over the surface to be deiced, thus removing the ice before the interfacial layer re-freezes. Another method of the present invention electromagnetically induces current at the ice-to-object interface, to melt interfacial ice, using coils and a high frequency power supply disposed proximal to the scraper.

摘要： A method and apparatus for forming mono-sized-dispersed spherical particles from a conductive liquid utilizes inductive coupling to cause a pressure oscillation in a plenum feeding a jet-forming nozzle. The inductive coupling is provided by a transformer where one loop is the conductive liquid. The invention also features a device with single or multiple orifice nozzle plates reliably manufactured using etching techniques. The invention also features methods for protecting jet-forming orifices from destruction attack by a corrosive liquid. The invention also features means to create simultaneously, tailored mixtures of mono-size-dispersed powder sizes. The invention also features a system and method for “pre-wetting” fine pores and orifices and for encouraging liquid penetration of the fine pores and filter without recourse to very high differential pressure.

摘要： An improved drill bit is provided with a sensor for monitoring an operating condition during drilling. A fastener system is provided for securing an erodible ball in a fixed position relative to a flow pathway until a predetermined operating condition is detected by the sensor, and for releasing the erodible ball into the flow pathway to obstruct the flow through at least one bit nozzle.

摘要： High power output may be obtained from a photovoltaic (PV) system by controlling each photovoltaic cell of a solar array individually to operate at its maximum power point. Each cell may have associated power electronics and control circuitry that may be integrated together on a chip which may be advantageously implemented in CMOS, enabling reductions in cost and size. A perturb and observe algorithm may be used to find the maximum power point by measuring the power produced at different operating points, and modifying the operating point in the direction of increased power production. In one aspect, performance of a perturb and observe algorithm may be improved in the presence of noise.
