  • Zinc air battery and its uses
    Patent number: 6879855
    Abstract: The invention is a method for increasing the airflow to a zinc-air battery such that the energy density is 500 mwh/cc to 1000 mwh/cc. This allows 8 to 16 hours use as a primary (throw-away) battery, with, for example, high-duty cycle, high-drain cochlear implants, and neuromuscular stimulators for nerves, muscles, and both nerves and muscles together. The systems incorporating the high energy density source are also part of the invention, as well as the resulting apparatus of the method. The uses of this inexpensive, i.e., a $1.00 per day, throw-away primary battery are new uses of the modified zinc-air battery and are directed toward helping people hear again, walk again, and regain body functionality which they have otherwise lost permanently.

  • Method and apparatus for managing product planning and marketing
    Publication number: 20050075923
    Abstract: Wine characteristic data is related to consumer liking data to provide a predictive model that may be used in wine portfolio management, including selection, shelf placement, pricing, and promotion. The wine characteristic data may relate to wine attributes as determined by a trained panel of experts or by chemical analysis, or to production or process data or to a combination of these data. The consumer liking data may be hedonic data obtained from consumer tasting. The predictive model may be a determined statistical relationship between the characteristic data and the hedonic data. In application, the predictive model may be used to identify what wines will appeal to various consumer segments. Alternatively, the predictive model may be used to identify for particular consumer segments or even individual consumers wines that may be liked.

  • Process for fabricating thin film transistors
    Publication number: 20050067656
    Abstract: Transistors are formed by depositing at least one layer of semiconductor material on a substrate comprising a polyphenylene polyimide. The substrate permits the use of processing temperatures in excess of 300° C. during the processes used to form the transistors, thus allowing the formation of high quality silicon semiconductor layers. The substrate also has a low coefficient of thermal expansion, which closely matches that of silicon, thus reducing any tendency for a silicon layer to crack or delaminate.

    Abstract: The invention relates to webs or batts including polytrimethylene terephthalate crimped staple fibers and fiberfill products comprising such webs and batts, as well as the processes of making the staple fibers, webs, batts and fiberfill products. According to the preferred process of making a web or batt, polytrimethylene terephthalate staple fibers, containing polytrimethylene terephthalate is melt spun at a temperature of 245-285° C. into filaments. The filaments are quenched, drawn and mechanically crimped to a crimp level of 8-30 crimps per inch (3-12 crimps/cm). The crimped filaments are relaxed at a temperature of 50-130° C. and then cut into staple fibers having a length of about 0.2-6 inches (about 0.5-about 15 cm). A web is formed by garnetting or carding the staple fibers and is optionally cross-lapped to form a batt. A fiberfill product is prepared with the web or batt.

  • Copolymers for photoresists and processes therefor
    Patent number: 6872503
    Abstract: Fluoroolefin/acid group or protected acid group-containing copolymers for photoresist compositions and microlithography methods employing the photoresist compositions are described. These copolymer compositions comprise 1) at least one fluoroolefin, preferably hexafluoroisobutylene, and 2) an acid group or a protected acid group (e.g., a t-alkyl ester, preferably a t-butyl ester), which together impart high ultraviolet (UV) transparency and developability in basic media to these materials. The materials of this invention have high UV transparency, particularly at short wavelengths, e.g., 157 nm and 193 nm, which makes them useful for lithography at these short wavelengths.

  • Electron collector
    Publication number: 20050062381
    Abstract: An electron collector assembly for an electron beam tube comprises an electron collector (2), which is at least partially surrounded by dielectric material, such as a dielectric fluid (5). A heat pipe (6), in communication with the dielectric fluid, is provided. Heat energy from the collector is transferred to the dielectric fluid, and hence to the heat pipe. By pumping coolant through the heat pipe, heat energy is removed from the vicinity of the collector. Previous proposals for cooling electron collectors necessarily involved non-conducting fluids as coolants. The provision of a dielectric fluid as an intermediary between the collector and the heat pipe allows greater freedom in the choice of coolant.
