  • Publication number: 20190219751
    Abstract: Double-notch filters for electronic devices are provided that filter light from both the blue spectrum as well as the red spectrum in narrow wavelength bands, or “notches.” A double-notch filter can, using input light from a conventional LED-backlit LCD display, output light that can be measured as substantially satisfying criteria for a D65 white point. In some examples, a double-notch filter can output light that can be measured as nearly satisfying criteria for a D65 white point, to within +/?500 Kelvin. In some examples, a double-notch filter can output light that can be measured as nearly satisfying criteria for a D65 white point, to within +/?1000 Kelvin.

  • Patent number: 7377639
    Abstract: A functional wafer of the present invention is disclosed to solve manufacturing difficulties involved in the production of optical elements such as polycarbonate ophthalmic lenses. The functional wafer may include a front layer, a functional layer, and a back layer, whereas the front layer and the back layer are bonded to the functional layer with or without additional adhesive. Said functional layer is smaller than at least the front layer by about 0.5 mm to 5 mm along the perimeter edge. A functional wafer of this construction can be conveniently and effectively incorporated into a lens through an insert injection molding process, in which said back layer will be in contact with the lens material.

  • Patent number: 6702595
    Abstract: A stable fuse clip for printed circuit boards has a vertical back plate, a pair of forwardly extending vertical flanges, and a rearwardly extending horizontal flange strengthened against bending. The horizontal flange, the bottom edges of the vertical flanges, and the bottom edge of the back plate are horizontally coplanar and rest on the surface of the circuit board. Two legs extend downwardly through the board from the lateral sides of the back plate, and one leg extends downwardly from the distal end of the horizontal flange.

  • Patent number: 6682875
    Abstract: A photoresist etching process and system can be used for the etching of non-planar or three-dimensional surfaces by using a non-planar shaped fiber optic array or fiber optic panel. The array or panel has a contour or shape that may nest a non-planar or three-dimensional article or surface. The non-planar or three-dimensional article or surface has a photoresist composition on its surface facing the optical fibers of the fiber optic array or panel, and the article or surface is nested against the contour or shape of the array or panel. Radiation is transported through the optical fibers and exposes the photoresist composition. The optical fiber array may perform an image-wise exposure of the photoresist composition by appropriate blockage of the radiation before it enters or as it enters a distal end of the optical fibers.

  • Patent number: 6618234
    Abstract: Damage to electronic golf course sprinkler valve controls from lightning current surges is prevented by electrically isolating the actual valve control circuit from the logic circuitry that controls it, using in the valve control circuit only components and printed traces that can withstand at least as much power dissipation as the field wiring, and grounding each valve control individually to earth ground through a plasma discharge device.

  • Patent number: 6562249
    Abstract: In an improved method of etching apertures in a thin metal sheet to form a shadow mask for a color picture tube, the metal sheet has a first acid-resistant stencil on one major surface thereof and a second acid-resistant stencil on the other major surface thereof. At least one of the stencils has openings therein at locations of intended apertures. The improvement comprises the steps of magnetically holding the metal sheet with a flat magnetic assembly, and moving the magnetic assembly magnetically holding the metal sheet thereon through an etching chamber. The magnetic assembly includes a magnetic layer that is supported on an acid-resistant board.

  • Publication number: 20020170878
    Abstract: Etch resistance of protein-based resist compositions can be improved by treatment of the resist coatings with oxidizing salts prior to exposure of the resist coating to etchant solutions. For example, protein-based, film forming compositions comprising casein, fish glue or albumin can be hardened by the treatment of oxidizing salts (such as chlorates, chlorites, perchlorates, bromates, iodates, periodates, perbromates, and hypochlorite). These salts can be used to harden the protein-based film-forming compositions without environmental damage by appropriate selection of the cation (e.g., sodium, lithium, potassium, calcium, ammonium, organic cations, and the like). Etch resistance is improved such that ferric chloride or other acidic etchant solutions can be used in etching the metal surface or substrate containing the casein-based photoresist.
