  • Cellular arrays for the identification of altered gene expression
    Patent number: 6716582
    Abstract: The present invention relates to the generation and use of a cellular array or a cellular array in combination with other genome-registered arrays (an array of arrays) for the determination of gene function and/or perturbation mode of action. Each cellular array consists of a number of microbial strains. Each strain comprises one reporter gene fusion made up of a gene or gene fragment operably linked to a reporter gene. Each gene or gene fragment has been “registered” or mapped to a specific location in the genome of the organism. The genome-registered collection of the invention may be used to determine alterations in gene expression under a variety of conditions. Such collections are amenable to rapid assay and may be used to confirm, correct or augment data generated from DNA micro array technology.

  • Moisture curable, melt processible graft ethylene copolymers
    Patent number: 6716920
    Abstract: The present invention relates to high performance wire and cable compositions and to hot melt adhesives containing a silyl-grafted ethylene copolymer having particularly low levels of glycidyl acrylate monomer.

  • Dual function single laser
    Patent number: 6714564
    Abstract: The invention is a dual function laser device for use in night vision systems. The invention uses lenses to cause one portion of a laser beam to converge to a target point and another portion of the beam to diverge. The divergent portion is variable in size and illuminates a viewable area around the target point. Rather than use two lasers to create an illuminated view area around an illuminated target point, the invention uses a combination of a lens and a sub-aperture lens arrangement to create two illuminations from a single laser.
