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.

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： In one embodiment, a system for modifying ice adhesion strength of ice adhered to an object. The system includes an electrode that is electrically insulated from the object and a DC source, e.g., a battery coupled to the object and the electrode. The source generates a DC bias to an interference between the ice and the object when the ice completes the circuit. The system preferably includes an electrically insulating material disposed-between the object and the electrode. In another embodiment, a coating comprising a ferroelectric, lossy dielectric, ferromagnetic or semiconductor material is applied to a object. Electromagnetic energy causes the coating to generate heat, which melts snow and ice.

摘要： A coating (626) comprising a ferroelectric, lossy dielectric, ferromagnetic or semiconductor material is disposed near an object (620). AC current flows through an electrical conductor (624), creating an electromagnetic field. The coating (626) absorbs energy from the electromagnetic field, thereby generating heat, which melts snow and ice on the object (620).

摘要： An alternating electric field is applied to ice (530) to generate a resistive AC having a frequency greater than 1000 Hz in interfacial ice at interface (554). A first electrode (510) and a second electrode (514) proximate to the interface are separated by an electrical insulator (512). An AC power source (520) provides a voltage of about 10 to 500 volts across the electrodes to create the alternating electric field. A portion of the capacitive AC associated with the alternating electric field is present in the interfacial ice as conductivity (resistive) AC, which causes dielectric loss heating in the interfacial ice.
