  • Method of surface manufacture with an apex decentered from a spindle axis
    Patent number: 8014894
    Abstract: The present invention is related to manufacturing surfaces with an axis decentered from the spindle axis. In particular, the present invention is related to compensating for tool geometry in cutting processes that involve an oscillating tool.
    Type: Grant
    Filed: October 9, 2007
    Date of Patent: September 6, 2011
    Assignee: Novartis AG
    Inventors: Stephen Kendig, Cornelius Daniel Niculas, Jason Emanuele Molinari, Nelson David Baity
  • Polishing of optical and non-optical tools for improved mold flow
    Patent number: 8002608
    Abstract: This invention is related to the process of polishing the optically critical surface of the front piece as well as the back piece, or non-optical surface, used to make molds used in double-sided molding process to make contact lens for reducing warpage of the mold, radius changes in different cavities and amount of cylindrical distortion. The polishing of both of the front piece and back piece causes the mold material to see a very similar coefficient of friction on both top and bottom surface and provides uniform flow front.

  • Method and apparatus for plasma generation
    Publication number: 20060237669
    Abstract: An RF-driven plasma source, including a pair of spaced-apart plasma electrodes, wherein the electrodes act as plates of a capacitor, the gas electrically discharges and creates a plasma of both positive and negative ions, in a clean process that enables efficient sample analysis, with preferred isolated sample photo-ionization, reduced-power operation and also including signal detection with modulated drive electronics.

  • Using higher order mathematical functions to create asymmetric molding back pieces
    Publication number: 20060055071
    Abstract: This invention is related to creation of a mold for an ophthalmic lens using higher order mathematical functions, such as non-uniform rational b splines (NURBs), to create surfaces that do not contact fluid optical material, such as molding back pieces. In particular, the present invention optimizes the flow of mold material. Additionally, use of the present invention creates substantially uniform thickness of the mold, minimizing optical distortions.
