  • Patent number: 11125919
    Abstract: A lighting device capable of manipulating a wider range of parameters to reproduce various light sources. A light source unit includes, for example, a liquid crystal panel and a backlight, and each pixel is a light source capable of adjusting innumerable hues and intensities capable of adjusting hue and intensity. A lenticular lens includes an array of a plurality of lenticules, and is arranged such that a plurality of light sources capable of adjusting hue and intensity is associated with each lenticule. In addition, on the outer periphery of the cylindrical portion of each lenticule, a partition is formed to block emission light from the pixel below the adjacent lenticule, thereby preventing repetition.

  • Patent number: 9393747
    Abstract: Disclosed is a method of manufacturing an optical element capable of increasing surface accuracy of an optical surface of an optical element with a plastic lens portion. A cavity which is formed when a pair of molds are closed has a compression molding space and an annular injection molding space, and the method includes a compression molding step of casting a compression molding material into the compression molding space of the molds and an injection molding step of injecting an injection molding material into the injection molding space in a state where the molds are closed and forming an injection molded portion at the outer circumferential edge of the compression molded compression molding material. In the injection molding step, before the compression molding material reaches a temperature lower than the glass transition temperature, the injection of the injection molding material starts.

  • Patent number: 9307654
    Abstract: This invention is directed to a method of forming a patterned multi-piece insert for an ophthalmic lens. The method may include forming first insert front and back curve pieces. The method may further include depositing a conductive material onto one or both of the first insert front and back curve pieces and attaching an electronic component at least in part to the conductive material. The method may further include placing an adhesive material onto a surface of one or both of the first insert front and back curve pieces so that a first ophthalmic insert is sealed when the first insert front and back curve pieces are combined. The method may further include combining the first insert back and front curve pieces to form the first ophthalmic insert and applying a colorant to at least one surface of one or both of the first insert back and front curve pieces.

  • Patent number: 9244195
    Abstract: The invention is related to a method for making a silicone hydrogel contact lens having a nano-textured surface which mimics the surface texture of cornea of human eye. A method of the invention comprises creating a prime coating having nano-textures through controlled imbibition and/or depositions of a reactive polymeric coating material and fixing the nano-textures by crosslinking a hydrophilic polymeric material onto the prime coating to form a crosslinked polymeric coating that perserves the nano-textures of the prime coating and provides a nano-textured surface to the contact lens.

  • Patent number: 9211187
    Abstract: A cranial implant molding device having a frame or base that receives a bottom or convex molding plate and a top or concave molding plate in a manner whereby the two plates are separated a distance to receive a settable or curable implant forming material therebetween. The plates are separated by a compressible member such that by the use of threaded mechanical fasteners or similar members the distance between the two plates can be adjusted by tightening or loosening the mechanical members. The thickness of the implant is varied by varying the separation distance on different sides of the frame.

  • Patent number: 9042024
    Abstract: The method includes the steps of: obtaining lateral magnification of an optical scanning system; obtaining the maximum value of thickness in the optical axis direction of an scanner lens; obtaining allowance b on one side and beam diameter a in the vertical scanning direction in the lens; and obtaining width h in the vertical scanning direction of the lens by the following expression h=a+2b. The allowance b is a product of the maximum value of thickness in the optical axis direction of the lens and a coefficient, and the coefficient is determined according to the lateral magnification of the system in such a way that the maximum value of movement of the focal point of the lens due to moisture absorption is made smaller than or equal to a predetermined value.

  • Patent number: 9005492
    Abstract: Described herein are methods for producing silicone hydrogel lenses. The methods involve introducing into a mold a water-based lens-forming composition, curing the lens-forming composition in a mold to form the lens, and removing the lens from the mold. The lens-forming composition comprises (i) a polysiloxane-containing vinylic monomer or macromer, (ii) at least one hydrophilic vinylic monomer, (iii) a surfactant, and, and (iv) water. The surfactant is polysiloxane-containing surfactant that is free of actinically-polymerizable groups and is a copolymer having from about 10% to about 40% by weight of one or more polysiloxane segments and from about 90% to about 60% by weight hydrophilic units and/or segments. The methods permit the use of water as a solvent and reduce the need for organic solvents. Additionally, the lenses produced by the methods can have improved properties such oxygen permeability.
