  • Publication number: 20100246703
    Abstract: A transmitter encodes an input bitstream using space-time trellis coding (STTC). The encoder includes a serial to parallel convertor to produce a first and second output bitstreams. First and second three bit shift registers are connected to produce first and second output bitstreams. A multiplier applies a code generating weight to each bit of the shift registers to encode the bitstreams. A first switch is connected between a last bit of the first shift register and a first bit of the second shift register. A second switch is connected between the second output and the first bit of the second shift register. The first set of encoded bit streams and the second set of encoded bitstreams are combined and mapped to a frequency domain.

  • Patent number: 7771666
    Abstract: The present invention provides a method and apparatus for the controlled synthesis of nanoparticles using a high temperature process. The reactor chamber includes a high temperature gas heated by means such as a plasma torch, and a reaction chamber. The homogenizer includes a region between the reactant inlets and the plasma (the spacer zone) to ensure that feeds from the reactant inlets are downstream of the recirculation zone induced by the high temperature gas. It also includes a region downstream of the reactant inlets that provides a nearly I dimensional (varying only in the axial direction) flow and concentration profile in the reaction zone to produce nanoparticles with narrow size distribution.

  • Publication number: 20090218253
    Abstract: Hermetically-sealed packages for electronic components, e.g., OLEDs, are provided. The packages have a first glass substrate (12), a second glass substrate (16), and a wall (14) that separates the first and second substrates (12,16) and hermetically seals the electronic component (18) between the substrates (12,16). The package has a reduced outer unused area characterized by distances Dfirst (32a) and Dsecond (32b) at least one of which, and, in certain embodiments, both of which are less than 200 microns, e.g., one or both of Dfirst (32a) and Dsecond (32b) is approximately 100 microns. The reduction in unused area can be used to increase viewing area, improve electrical lead design, and/or increase package strength through the use of a wider sintered frit wall (14).

  • Publication number: 20090221207
    Abstract: A method of hermetically sealing a glass assembly comprising glass plates or substrates with a glass-based frit when there is a large difference between the coefficient of thermal expansion (CTEs) of the frit and the CTEs of the glass plates. The method comprises a rapid increase of an irradiating heat source, used to heat and soften the frit, from a non-sealing power to a sealing power over a very short distance along the frit to form an initial stabilizing seal between the substrates.

  • Publication number: 20090133807
    Abstract: An apparatus for sealing a substrate assembly by applying a force to the assembly while simultaneously exposing the substrate assembly, and in particular a sealing material disposed between two substrates of the substrate assembly, to an irradiating beam of electromagnetic energy. The beam heats, cures and/or melts the sealing material, depending upon the sealing material to form the seal. The force is applied by directing a flow of fluid against the substrate assembly, and beneficially improves contact between the substrates of the substrate assembly and the sealing material during the sealing process, therefore assisting in achieving a hermetic seal between the substrates.

  • Publication number: 20090044496
    Abstract: An apparatus for sealing a glass package by applying a force to a glass assembly while simultaneously irradiating a sealing material disposed between the two glass substrates with a beam of radiation. The applied force is translated in unison with the radiation beam. The radiation cures and/or melts the sealing material, depending upon the sealing material. The applied force beneficially improves contact between the glass substrates and the sealing material during the sealing process, therefore assisting in achieving a hermetic seal between the substrates.
