  • Patent number: 8736049
    Abstract: Micro-plasma is generated at the tip of a micro-spring by applying a positive voltage to the spring's anchor portion and a negative voltage to an electrode maintained a fixed gap distance from the spring's tip portion. By generating a sufficiently large voltage potential (i.e., as determined by Peek's Law), current crowding at the tip portion of the micro-spring creates an electrical field that sufficiently ionizes neutral molecules in a portion of the air-filled region surrounding the tip portion to generate a micro-plasma event. Ionic wind air currents are generated by producing multiple micro-plasma events using micro-springs disposed in a pattern to produce a pressure differential that causes air movement over the micro-springs. Ionic wind cooling is produced by generating such ionic wind air currents, for example, in the gap region between an IC die and a base substrate disposed in a flip-chip arrangement.

  • Patent number: 8080930
    Abstract: Spindt-type field-emission cathodes for use in electric propulsion (EP) systems having self-assembling nanostructures that can repeatedly regenerate damaged cathode emitter nanotips. A nanotip is created by applying a negative potential near the surface of a liquefied base metal to create a Taylor cone converging to a nanotip, and solidifying the Taylor cone for use as a field-emission cathode. When the nanotip of the Taylor cone becomes sufficiently blunted or damaged to affect its utility, the base metal is re-liquefied by application of a heat source, a negative potential is reapplied to the surface of the base metal to recreate the Taylor cone, and a new nanotip is generated by solidifying the base metal.
