  • Patent number: 10353124
    Abstract: A reflection optical filter has an ultra-thin semi-transparent layer and a thin layer of semiconductor (or dielectric) layer deposited onto a metal film surface at a certain thickness corresponding to a wavelength of light to be filtered from incoming light. Critical coupling of light to the optical cavity formed by the semi-transparent layer and semiconductor (or dielectric) layer on metal surface results in near perfect absorption of the light at one wavelength and strong absorption in the wavelength region near the peak absorption wavelength. Incoming lights of other wavelengths are mostly reflected by the device so the spectral content of incident light is changed. By controlling the thickness of the semiconductor (or dielectric) layer and/or other factors, such as the extent to which the semiconductor layer is annealed or changing the type of metal beneath the semiconductor (or dielectric) layer, the peak absorption wavelength of the light absorbed in the device can be precisely controlled.

  • Patent number: 9628179
    Abstract: A system and method for filtering and enhancing signals from a noise background based on the nonlinear interaction of waves. The system and method amplify low-level signals, hide information in the signals, and then nonlinearly recover the signals. With the present invention, this can be performed for both spatial beams and temporal pulses. The signal self-filters and self-amplifies at the expense of the surrounding noise via the nonlinear medium.

  • Patent number: 9625627
    Abstract: The belt ply feeder and a feeding method include: when a belt ply is conveyed to the front end of a conveying forming board, a force is exerted by a perpendicular adjustment device to drive a conveying forming board bracket to swing upward and rotate around a pivot shaft of a rack to positions at which the upper surface of the conveying forming board is tangential to the periphery of a belt ply drum. According to this arrangement, the belt ply is tangential to the belt ply drum all the time and a belt ply is in firm contact with a belt ply drum regardless of the size of the belt ply drum when wrapping the belt ply around the belt ply drum. Accordingly, the quality of tire shaping can be improved.

  • Patent number: 9515119
    Abstract: A variable optical filter is disclosed including a bandpass filter and a blocking filter. The bandpass filter includes a stack of alternating first and second layers, and the blocking filter includes a stack of alternating third and fourth layers. The first, second and fourth materials each comprise different materials, so that a refractive index of the first material is smaller than a refractive index of the second material, which is smaller than a refractive index of the fourth material; while an absorption coefficient of the second material is smaller than an absorption coefficient of the fourth material. The materials can be selected to ensure high index contrast in the blocking filter and low optical losses in the bandpass filter. The first to fourth layers can be deposited directly on a photodetector array.

  • Patent number: 9329311
    Abstract: The present disclosure provides a light control film that is capable of transmitting light, or allowing a viewer to observe information, only within a viewing region centered around the normal (perpendicular line) to a surface. The light control film generally blocks information or light outside of this viewing region, and provides security in all directions including right-and-left and up-and-down of the film. The light control film includes a plurality of light-transmissive cavities that are surrounded by a light absorbing material, such that each of the plurality of cavities is optically isolated from adjacent cavities. Each of the light-transmissive cavities effectively block light which enters the cavity outside of a viewing (that is, cutoff) angle.

  • Patent number: 9242278
    Abstract: Disclosed herein is a high-efficiency acoustic wave generator using a pulsed thermal radiation beam. The generator is configured such that when a pulse beam formed by a light interrupter is directly radiated onto a porous material having a woven net or steel scrubber shape, thin wires of the porous material repeatedly rapidly thermally-expand and contract, whereby air in the space between the wires is momentarily heated and cooled, and the expansion and contraction of air is directly transmitted to an air column formed just adjacent to the porous material. By virtue of the above structure, the efficiency of the generator is markedly improved compared to the conventional technique, and the productivity is also greatly enhanced.
