Andriy Dobrovolskyy 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).

  • Method of plasma beam bombardment of aligning films for liquid crystals
    Patent number: 7777850
    Abstract: Methods for treating aligning substrates produces uniform alignment of liquid crystals in at least two modes. The method is based on the treatment of liquid crystal aligning substrates with a collimated or partially collimated plasma beam. In one embodiment, the method comprises a step of bombarding an aligning substrate with at least one plasma beam from a plasma beam source at a designated incident angle to align the atomic/molecular structure or the surface profile of the aligning substrate in at least one aligned direction.
    Type: Grant
    Filed: September 4, 2008
    Date of Patent: August 17, 2010
    Assignee: Kent State University
    Inventors: Liang-Chy Chien, Andriy Dobrovolskyy, Oleg Yaroshchuk, Oleg Lavrentovich
