  • Patent number: 10678058
    Abstract: Systems, devices, and methods for embedding a diffractive element in an eyeglass lens are described. A method of embedding a diffractive element in an eyeglass lens includes applying a protective layer to a diffractive element, applying an interface layer to the protective layer, and applying a lens layer to the interface layer. The interface layer and the lens layer are each comprised of a resin material that hardens when cured. The interface layer is of a shape and thickness that adheres well to the protective layer after the interface layer is cured. The lens layer is of a shape and thickness that achieves the desired component shape of the lens after the lens layer is cured.

  • Patent number: 10624730
    Abstract: Formulations of shape memory polymer (SMP) are integrated with several existing clinically available medical fabrics. The SMP portion of a SMP-integrated fabric can be fabricated in varying thicknesses with the minimum thickness determined by the thickness of the underlying fabric and up to almost any thickness. Integration of the SMP with the base fabrics does not alter the shape memory functionality of the SMP. The design tools for controlling activation rate for traditional SMP materials thus apply to SMP-integrated fabrics. SMP-integrated fabrics may also be steam sterilized without loss of shape memory functionality.

    Abstract: A display includes an upper surface adapted to present visual information to a device user and an outer perimeter proximate the upper surface. An optically transparent lens is carried by a housing and overlies the display. The optically transparent lens and the upper portion of the housing together define an upper surface of the portable electronic device. An optically transparent resin is carried between the display and the optically transparent lens. The optically transparent resin includes a perimeter portion disposed between the outer perimeter of the display and the side portion of the housing. The resin can be cured using light.

  • Publication number: 20140284826
    Abstract: A device includes a feed unit containing hot melted UV curable glue, a first pressing roller defining a first central axis, a second pressing roller defining a second central axis, and two UV lamp assemblies received in the two pressing rollers respectively. The first pressing roller rotates about the first central axis in a first direction. The second pressing roller rotates about the second central axis in a second direction opposite to the first direction. The first central axis and the second central axis are arranged on a common horizontal plane and parallel to each other. A molding channel is formed between the two pressing rollers. The two pressing rollers cooperatively press the hot melted UV curable glue transmitted into the molding channel from the feed unit. The UV lamp assemblies emit UV light beams to solidify the pressed UV curable glue to form an optical film.

  • Patent number: 8828283
    Abstract: An optical component and a method of producing the same, which optical component is obtained by photopolymerizing a photopolymerizable composition so as to comprise a matrix and numerous columnar structure bodies oriented in one direction within the matrix, wherein the columnar structure bodies differ in refractive index from the matrix and are arrayed in a lattice in the plane perpendicular to said orientation direction to have a highly arrayed structure whose refractive index periodically changes on the order of 80 nm to 1,000 micrometer. The optical component according to the invention is imparted with a structure whose refractive index periodically changes with high regularity on the order of about 80 nm to 1,000 micrometer and, owing to this property, is usable in optical sheet, optical film and other ordinary optical applications.

  • Publication number: 20140232028
    Abstract: An element includes a first resin layer and a second resin layer disposed between a first glass lens substrate and a second glass lens substrate, a boundary surface between the first resin layer and the second resin layer having a diffraction grating shape including a plurality of inclined surfaces and wall surfaces. The second resin layer is composed of a fluororesin in which fine metal oxide particles are dispersed. Since a refractive index distribution easily occurs in this material during curing by application of ultraviolet light, by applying ultraviolet light substantially perpendicular to the inclined surfaces of the diffraction grating shape, a refractive index distribution is formed in the thickness direction perpendicularly to the inclined surfaces.
