Abstract: A composite polymer fiber comprises a polymer filler material and a plurality of polymer scattering fibers disposed within the filler material. At least one of the filler material and the scattering fibers is formed of a birefringent material. The refractive indices of the filler material and the scattering fibers can be substantially matched for light incident in a first polarization state on the composite polymer fiber and unmatched for light incident in an orthogonal polarization state. The scattering fibers may be arranged to form a photonic crystal within the composite fiber. The composite fibers may be extruded and may be formed into a yarn, a weave or the like. If the filler material is soluble, it may be washed out of the yarn or weave, and the scattering fibers may then be infiltrated with a resin that is subsequently cured.

Abstract: A field effect transistor includes a thin layer of discontinuous conductive clusters between the gate dielectric and the active layer. The active layer can include an organic semiconductor or a blend of organic semiconductor and polymer. Metals, metal oxides, predominantly non-carbon metallic materials, and/or carbon nanotubes may be used to form the layer of conductive clusters. The conductive clusters improve transistor performance and also facilitate transistor fabrication.

Abstract: A process of forming a microperforated plastic film includes providing a post tool having multiple posts, bringing plastic into contact with the post tool such that the plastic conforms to the shape of the posts, and solidifying the plastic into a solidified plastic film having a plurality of microperforations in the shape of the posts. Another step in the process is displacing any skins formed over the holes after solidifying the plastic. The process may be used to form a film for sound absorption where the posts are shaped and arranged to provide microperforations that provide a particular sound absorption spectrum. In one embodiment, the microperforations each have a narrowest diameter of 20 mils, a narrowest diameter less than a film thickness, and a widest diameter greater than narrowest diameter. The widest diameter may be about 125% or more of the narrowest diameter in an embodiment.
Abstract: The present invention relates to the prevention of electro-chemical corrosion at charging pins, especially of a battery-powered handpiece and its charging station.
Abstract: An acoustic system for applying vibratory energy including a horn connected to an ultrasonic energy source. The horn defines an overall length and wavelength, and at least a leading section thereof is comprised of a ceramic material. The leading section has a length of at least ? the horn wavelength. In one preferred embodiment, an entirety of the horn is a ceramic material, and is mounted to a separate component, such as a waveguide, via an interference fit. Regardless, by utilizing a ceramic material for at least a significant portion of the horn, the ultrasonic system of the present invention facilitates long-term operation in extreme environments such as high temperature and/or corrosive fluid mediums. The present invention is useful for fabrication of metal matrix composite wires.

Abstract: An LED illumination system includes control circuitry and first, second and third colored LEDs. The control circuitry sequentially drives the first, second and third colored LEDs in a color cycle frame with relative duty cycles having a known relationship that achieves a color balance. The control circuitry also operates to introduce at least one spoke period in the color cycle frame, during which the first, second and third LEDs are driven in a manner that is controlled to provide brightness adjusting light that matches the color balance achieved by the relative duty cycles of the first, second and third LEDs during sequential driving thereof.
Abstract: A gas diffusion layer incorporating a gasket (GIG) is described along with assemblies incorporating the GIG subassembly. Processes for making the GIG and membrane electrode assemblies (MEAs) incorporating the GIG are also described. A GIG subassembly includes a gas diffusion layer (GDL) and a gasket bonded to the GDL. The gasket includes a first gasket layer and a second gasket layer. The second gasket layer is formed of a gasket material in contact with the first gasket layer and the GDL. The gasket material of the second gasket layer bonds the GDL to the first gasket layer. An adhesive layer, and optionally a removable adhesive liner, is disposed on a surface of the first gasket layer opposite the second gasket layer. In some MEA configurations, the GDL is disposed within an aperture in the first gasket layer.
