  • Patent number: 8120837
    Abstract: A display media particle used for an information display panel having display media constituted of particles sealed between two substrates, at least one of which is transparent, for displaying information by moving the display media, is formed of a mother particle 32 made from materials including a base resin having child particles 33 added to a surface thereof. The base resin is a thermoplastic resin having a viscosity of no more than 1000 Pa·s at 260° C. and a shear rate at 122 s?1, and a heatproof temperature at no less than 430° C. Since optimal conditions of the viscosity and the heatproof temperature are specified, it is possible to round the resin effectively by a heat treatment for spheronization as a post-treatment after manufacturing.

  • Patent number: 8023175
    Abstract: A preferred embodiment comprises a dynamic display based on a program image element which will only generate a preprogrammed image. As an example, the image element may comprise electrically-driven MEMS mirrors. This example may be embedded in an ID card. At the time of issue of the ID card, pixels in the mirror array will be permanently programmed as either ‘alive’ or ‘dead’ in a pattern matching the photo of the person in question. When stimulated, only ‘alive’ pixels will actuate, creating an image for comparison to the adjacent printed photo. Due to its dynamic behavior, delicate mechanical structures, and single-time hard-wiring, duplication of, or tampering with, this secondary dynamic image will be nearly impossible. The ID car is but one exemplary application and other embodiments, applications, and methods are described in the specification and claims.

    Abstract: A lens assembly includes a barrel having an object-side opening and an image-forming-side opening. The barrel further has a positioning section that positions an image-forming-side surface of a lens by having line contact around an optical axis at a center. The positioning section is disposed at a position that is closer to an object side than the image-forming-side opening of the barrel is. The barrel also has an image-forming section that extends from the positioning section to a center of the optical axis along the image-forming-side surface of the lens and forms an edge of the image-forming-side opening of the barrel.

  • Patent number: 8014072
    Abstract: An erecting equal-magnification lens array plate includes a stack of a plurality lens array plates built such that pairs of corresponding lenses form a coaxial lens system, where each lens array plate is formed with a plurality of convex lenses on both surfaces of the plate. The plate receives light from a substantially straight light source facing one side of the plate, and the plate forms an erect equal-magnification image of the substantially straight light source on an image plane facing the other side of the plate. A light shielding member operative to shield light not contributing to imaging is formed in the neighborhood of a position in the intermediate plane in the erecting equal-magnification lens array plate where an inverted image of the substantially straight light source is formed. The main lens arrangement direction of the convex lenses differs from the main scanning direction of the erecting equal-magnification lens array plate.

  • Patent number: 7990620
    Abstract: A head-up display system is described. The head-up display system includes an image projection device, a diffusion unit, and a frame demonstration medium. The image projection device emits the visible light, containing text or image information, for generating a real image on the diffusion unit. The frame demonstration medium receives the visible light reflected from the diffusion unit. By adjusting the received visible light reflected from the diffusion unit, the frame demonstration medium generates a virtual image corresponding to the real image. The distance between the real image corresponding to the diffusion unit and the frame demonstration medium is preferably equal to the distance between the virtual image and the frame demonstration medium. Alternatively, the visible light is projected to the frame demonstration medium and then reflected to the diffusion unit.

  • Patent number: 7957068
    Abstract: Long-distance transfer of a super-resolution near field can be performed with a wavelength condition of high degree of freedom. Not only an image in same size can be merely transferred, but also a magnified image can be transferred. Thus the processing technique of a near-field image is improved. Small rods are erected at predetermined spacing with one another on a two-dimensional plane. At least the exterior surface of each small rod is made of a predetermined material having a dielectric constant ?m meeting the condition “?m???d” where ?d is the dielectric constant of the surrounding medium. The axes of the small rods can be extended to a predetermined direction with respect to the two-dimensional plane. An optical near-field is incidented to one end of each small rod.
