  • Conduits integrated in circuit board and method of manufacture
    Patent number: 6901217
    Abstract: Circuit boards (1100, 1400) and methods for fabricating circuit boards that include conduits (1004) are provided. The conduits formed by patterning a metal layer (1102) are lined by inert coating (1106) and caped by a photodefinable polymer layer (1110) that is affixed to the inert coating by with the help of an initially uncured polymer layer (1106). Holes are formed by patterning the photodefinable polymer layer for admitting and removing fluid from the conduit.
    Type: Grant
    Filed: February 28, 2003
    Date of Patent: May 31, 2005

  • Optical path method and apparatus
    Patent number: 6891991
    Abstract: A mesoscale micro electro-mechanical systems (MEMS) structure comprises an optical interface member (18) that moves with a pivoting member (15). Such movement serves to occlude and/or to complete an optical signal pathway (19).

  • Alkaline gel electrolyte for electrochemical cells
    Patent number: 5585208
    Abstract: An alkaline gel electrolyte for an electrochemical cell is based on a polymeric binder of polyvinyl alcohol or polyvinyl acetate. Potassium hydroxide and/or sodium hydroxide is blended into the polymeric binder or matrix, and the resulting solution is used to cast a film that is useful as a gel electrolyte. The hydroxide in the solution is between about 1% to 25% by weight, and the polymer concentration is between about 0.5% to 10% by weight. The resulting gel electrolyte film contains between 10 to 90% water by weight. A nickel or iron porphine modifier may be added in an amount between about 1 to 1000 parts per million. The alkaline gel electrolyte is useful in combination with asymmetric inorganic electrodes to make electrochemical cells, and can also function as a separator. Improved power density and higher cycle life is achieved with the gel electrolyte.
