Patents by Inventor Kwan Kwok

Kwan Kwok has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060251204
    Abstract: The invention describes a product and a method for generating electrical power directly from nuclear power. More particularly, the invention describes the use of a liquid semiconductor as a means for efficiently converting nuclear energy, either nuclear fission and/or radiation energy, directly into electrical energy. Direct conversion of nuclear energy to electrical energy is achieved by placing nuclear material in close proximity to a liquid semiconductor. Nuclear energy emitted from the nuclear material, in the form of fission fragments or radiation, enters the liquid semiconductor and creates electron-hole pairs. By using an appropriate electrical circuit an electrical load is applied and electrical energy generated as a result of the creation of the electron-hole pairs.
    Type: Application

  • Patent number: 6646638
    Abstract: A driving scheme for a liquid crystal display of any order and dimension, comprising matrix building blocks possessing Orthogonal and Shift Orthogonality properties. The driving scheme uses paraunitary matrices of the order M×(N+1)M as the orthogonal building blocks.

  • Patent number: 6573971
    Abstract: A bistable twisted nematic LCD cell is presented. The cell includes front and rear polarizes, substrates and a liquid crystal layer between the substrates. Rubbing directions are arranged to give an initial twist angle of the liquid crystal, arranged such that the cell does not make a configuration with an initial twist angle of 180° and wherein an initial twist angle is not a multiple of 90°, and a twist angle is in the range of 30-80°, with a retardation in the range of 0.33-0.44 &mgr;m.
