Publication number: 20140009700Abstract: Aspects of the present invention provide an electro-active lens and method for manufacturing the same that encapsulates liquid crystal using solid transparent optical material using an improved liquid crystal seal feature. The seal feature greatly reduces the visibility of the liquid crystal seal feature in an assembled electro-active lens. The seal feature is also structurally robust such that the electro-active lens can be processed to fit a spectacle frame without disturbing containment of the liquid crystal and without disrupting electrical connectivity to the lens used to alter the refractive index of the liquid crystal, thereby ensuring fabrication of a commercially viable electro-active lens.Type: ApplicationFiled: August 5, 2013Publication date: January 9, 2014Applicant: PixelOptics, Inc.Inventors: Joshua N.

Patent number: 8464771Abstract: A multi-layer laminate media is provided on which information may be applied in machine or human readable form on a visible front surface by the output of one or more lasers, or other high intensity light source. In a preferred embodiment, the media has three layers including preferably transparent substrate, a thermochromic layer and a light absorbent layer located intermediate the media substrate and the thermochromic layer. The light absorbent layer is adapted to absorb light from the light source and convert the absorbed light into heat. The heat is immediately conducted into selected portions of the thermochromic layer which is in thermal contact with the light absorbent layer, causing portions of the thermochromic layer to change visual appearance such as color to create the desired mark. The media optimally includes obscuration materials to reduce the visibility of the light absorbent layer to the naked eye.Type: GrantFiled: November 12, 2010Date of Patent: June 18, 2013Assignee: Sinclair Systems International LLCInventors: M. Scott Howarth, Colin P. Woodward, Neil Griffin, Sam Hyde, Roger Clarke, Richard Calusdian, Wilson B. Murray, Richard Hirst, Richard Evans, Enrique B.

Patent number: 8319937Abstract: An alignment layer may align molecules of a liquid crystalline material to a surface of a substrate having a diffractive optical power region using a nonlinear alignment. The alignment layer may align the molecules of the liquid crystalline material in one of a tangential alignment, a piecewise tangential alignment, a perpendicular alignment, a piecewise perpendicular alignment, a continuous intra-zone alignment, or a piecewise continuous intra-zone alignment. The nonlinear alignment may result in optimal or near optimal alignment of the liquid crystalline material thereby resulting in improved optics and fewer vision compromises.Type: GrantFiled: April 11, 2008Date of Patent: November 27, 2012Assignee: PixelOptics, Inc.Inventors: Roger Clarke, Joshua N.
