  • Patent number: 8009254
    Abstract: A liquid crystal display apparatus includes a liquid crystal layer sealed between a first substrate and a second substrate opposed to each other. Inner surfaces of the first and second substrates have been subjected to aligning treatment to splay-align liquid crystal molecules. The liquid crystal display further includes electrodes formed on the inner surfaces of the first and second substrates to generate an alignment transition electric field to cause the liquid crystal molecules to transit from splay alignment to bend alignment. The alignment transition electric field includes a vertical electric field in the thickness direction of the liquid crystal layer, and a horizontal electric field in a direction parallel to the inner surfaces of the first and second substrates to twist the liquid crystal molecules between the substrates.

  • Patent number: 7986860
    Abstract: Systems and methods are described that employ high-intensity lasers to set up a thin plasma sheet, also called a waveguide or “hot shell”, in the atmosphere as a function of beam intensity and geometry. A laser beam can be spread and directed with physical optics (e.g., lenses, mirrors, other optical elements, etc.) to generate a thin inverted cone-shaped hot shell waveguide in the atmosphere. The hot shell of the waveguide has a different index of refraction (n) from that of the surrounding air layers and as such serves to internally reflect portions of the entering solar rays entering an aperture in the hot shell, toward the tip of the cone and a solar energy storage component positioned there, thus providing a virtual solar energy concentration system. In another embodiment, the solar energy storage component shuts down or otherwise rejects incoming solar energy when fully charged, to mitigate damage to system components.
