Patents by Inventor Moses Mekala David

Moses Mekala David 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).

  • Patent number: 7496255
    Abstract: A glass article comprising a glass substrate and a diamond-like film deposited on the substrate is disclosed. The glass article is desirably responsive to actinic radiation, such as being capable of demonstrating a change in refractive index upon exposure to actinic radiation. The film permits passage of the actinic radiation through the film and into the substrate. In specific implementations, the film comprises at least about 30 atomic percent carbon, from about 0 to about 50 atomic percent silicon, and from about 0 to about 50 atomic percent oxygen on a hydrogen-free basis.
    Type: Grant
    Filed: June 22, 2004
    Date of Patent: February 24, 2009
    Assignee: 3M Innovative Properties Company

  • Patent number: 7125603
    Abstract: The application discloses methods of plasma treatment that employ an ion sheath in a capacitively-coupled system to increase the hydrophilicity of porous articles, including microporous articles having pore sizes of 0.05 to 1.5 micrometers, both on their surfaces and in their pores such that the articles' bulk wetting properties are improved.
    Type: Grant

  • Patent number: 6696157
    Abstract: A diamond-like glass film is disclosed. In specific implementations, the film includes a diamond-like glass containing at least about 30 atomic percent carbon, at least about 25 atomic percent silicon, and less than or equal to about 45 atomic percent oxygen on a hydrogen-free basis. The diamond-like glass film may be applied to various substrates. The invention is also directed to articles having a diamond-like glass film, methods of making the articles, and apparatus for making the film and to articles.

  • Publication number: 20030134515
    Abstract: The application discloses articles and methods of plasma fluorination treatment that employ a capacitively-coupled system to fluorinate porous articles. The methods include placing the article to be treated within an ion sheath adjacent to an electrode and placing the article to be treated between powered and grounded electrodes separated by about 25 mm or less.
