  • Publication number: 20110262093
    Abstract: A light extraction film having internal nanostructures and external microstructures for organic light emitting diode (OLED) devices. The light extraction film includes a flexible substantially transparent film, a low index nanostructured layer applied to the film, and a high index planarizing backfill layer applied over the nanostructured layer. External optical microstructures are applied to the flexible substantially transparent film on a side opposite the nanostructured layer to enhance light extraction from the OLED devices while providing for a more uniform luminance distribution.

  • Publication number: 20110241650
    Abstract: An electrochemical sensor to measure disinfectants is provided. In accordance with one aspect of the invention, the sensor has a silver working electrode disposed in an electrolyte proximate a porous membrane. There is a reference electrode made of silver in contact with the electrolyte. The chemical composition of electrolyte contains one or more anions that make the potential at the reference electrode higher than 0.35 V versus standard hydrogen electrode. The anions form silver salt with solubility higher than the solubility of silver chloride. The voltage at the working electrode versus the reference electrode is maintained negative to keep the background current small enough while maintains the feasibility to reduce disinfectants. Solid phase silver salt of the anions is added within the sensor body, which will prevent poisoning the reference electrode by halide anions diffused into the electrolyte.

  • Publication number: 20110229992
    Abstract: A multifunctional optical film for enhancing light extraction includes a flexible substrate, a structured layer, and a backfill layer. The structured layer effectively uses microreplicated diffractive or scattering nanostructures located near enough to the light generation region to enable extraction of an evanescent wave from an organic light emitting diode (OLED) device. The backfill layer has a material having an index of refraction different from the index of refraction of the structured layer. The backfill layer also provides a planarizing layer over the structured layer in order to conform the light extraction film to a layer of an OLED lighting device such as solid state lighting devices or backlight units. The film may have additional layers added to or incorporated within it to an emissive surface in order to effect additional functionalities beyond improvement of light extraction efficiency.

  • Patent number: 8005002
    Abstract: One embodiment of the present invention provides a system that performs a query-based convergecast scheduling in a convergecast network, which includes a base-station and a plurality of nodes. During operation, the system receives a convergecast tree for the convergecast network. Each node in the convergecast tree is associated with a hop-count to the base-station through a specific branch and each node can generate zero or more packets to transmit. Next, the system initializes a query from the base-station, wherein the query is successively propagated to the nodes through the branches. In response to the query, the system computes distributed-timing-information indicating a packet transmission schedule for the nodes. The system next aggregates the distributed-timing-information associated with the nodes toward the base-station through the branches. The system then forwards the aggregated distributed-timing-information to the plurality of nodes.

  • Patent number: 8003455
    Abstract: A method for processing CMOS wells, and performing multiple ion implantations with the use of a single hard mask is disclosed. The method includes forming and patterning a hardmask over a substrate, whereby the hardmask attains a first opening. The substrate may be a semiconductor substrate. The method further includes performing a first ion implantation, during which, outside the first opening the hardmask is essentially preventing ions from reaching the substrate. The method further involves the application of a photoresist in such a manner that the photoresist is covering the hardmask, and it is also filling up the first opening. This is followed by using the photoresist to pattern the hardmask, whereby the hardmask attains a second opening. The method further includes performing a second ion implantation, during which, outside the second opening, the hardmask and the photoresist, which fills the first opening, are essentially preventing ions from reaching the substrate.

  • Publication number: 20110143482
    Abstract: A vertical stack of a first silicon germanium alloy layer, a second epitaxial silicon layer, a second silicon germanium layer, and a germanium layer are formed epitaxially on a top surface of a first epitaxial silicon layer. The second epitaxial silicon layer, the second silicon germanium layer, and the germanium layer are patterned and encapsulated by a dielectric cap portion, a dielectric spacer, and the first silicon germanium layer. The silicon germanium layer is removed between the first and second silicon layers to form a silicon germanium mesa structure that structurally support an overhanging structure comprising a stack of a silicon portion, a silicon germanium alloy portion, a germanium photodetector, and a dielectric cap portion. The germanium photodetector is suspended by the silicon germanium mesa structure and does not abut a silicon waveguide. Germanium diffusion into the silicon waveguide and defect density in the germanium detector are minimized.
