Jon Herman Ulvensøen 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 for manufacturing adjustable lens
    Patent number: 8883019
    Abstract: The present invention provides method steps for manufacturing an assembly of adjustable lenses on a wafer. The method steps provide an easy manufacturing of such lenses, minimizing the cost of assembly, and at the same time provide a solution for mass production of compact adjustable lenses for use in mobile phones, etc.
    Type: Grant
    Filed: October 5, 2007
    Date of Patent: November 11, 2014
    Assignee: Polight AS
    Inventors: Lars Henriksen, Morten Eliassen, Vladimir Kartashov, Jon Herman Ulvensøen, Ib-Rune Johansen, Karl Henrik Haugholt, Dag Torstein Wang, Frode Tyholdt, Wilfred Booij
  • Method and arrangement for reducing thermal effects in compact adjustable optical lenses
    Patent number: 8310772
    Abstract: The present invention provides thermal compensation for a lens assembly comprising a polymer lens body. Polymers do have different thermal expansion coefficients which makes it necessary to compensate for thermal expansions to keep optical characteristics of such lenses within specifications when used under different environmental conditions. Also, it is necessary to provide thermal compensation during manufacturing of such lenses due to high temperatures during manufacturing steps.
    Type: Grant

  • Compact adjustable lens
    Patent number: 8045280
    Abstract: The present invention provides a solution for designing a compact adjustable lens assembly, wherein a circular shaped piezoelectric crystal is bending a thin glass cover, thereby providing a shift of focal length of the lens assembly.
