  • Method and apparatus for determining gene expression levels
    Patent number: 6816790
    Abstract: Techniques for analyzing gene expression levels are provided. In one aspect of the invention, the technique provides a method for determining a concentration level of a target nucleic acid, the target nucleic acid comprising at least one target oligonucleotide. The method determines (i) a measure of affinity value of the target oligonucleotide with a probe oligonucleotide; and (ii) a hybridization intensity value for the target oligonucleotide and the probe oligonucleotide at a probe spot. The measure of affinity value and the hybridization intensity value are used to determine the concentration level of the target nucleic acid.
    Type: Grant
    Filed: February 13, 2003
    Date of Patent: November 9, 2004
    Assignee: International Business Machines Corporation
    Inventors: Geoffrey Grinstein, Glenn Allen Held, Yuhai Tu

  • Liquid crystalline light-modulating device
    Patent number: 6540938
    Abstract: The present invention relates to a light-modulating composition comprising a low molecular weight liquid crystalline material dispersed in a polymer including a non-mesogenic crosslinking monomer reacted with a mesogenic monomer comprising a mesogenic group, a spacer, and one or more reactive functionality.

  • Polymer stabilized in-plane switched LCD
    Patent number: 6177972
    Abstract: An in-plane switched liquid crystal device IPS LCD which provides fast switching times is formed by filling an empty IPS LCD panel having an array of display elements with a mixture of nematic liquid crystal material and a mesogenic polymerizable material, such as monomers or polymer precursers and suitable photoinitiators, curing, or cross-linking agents, and then polymerizing the mixture such that a phase-separated network of cross-linked polymer strands is formed. The cross-linked network of polymer strands displays an average orientation whose average orientation substantially conforms with nematic orientation of the nematic liquid crystal material in its “field-off” state.
