  • Patent number: 10663670
    Abstract: An optical connector for connecting single mode optical fibers includes a ferrule that connects to and holds an optical fiber, and a resin optical element coupled to the ferrule and that includes a lens positioned relative to an end of the optical fiber held in the ferrule, and the lens is provided with an antireflection structure. When the optical connector is oppositely connected to another identical optical connector, the opposing optical elements are disposed such that a diverging light is emitted from the end of the optical fiber, transmitted through the lens, and emitted as a collimated beam of light, and the collimated beam of light is incident on an opposing lens of the opposing, identical optical connector and condensed onto an end of an opposing optical fiber of the opposing, identical optical connector.

  • Patent number: 10591186
    Abstract: A mechanical solar tracking and solar concentrating system having a Fresnel lens, moveable frame, track, retaining mechanism, and solar collector. The lens focuses solar energy at the collector; the frame holds the collector and lens, keeping them aligned as the frame rotates; and the track guides the frame to maintain a perpendicular orientation to the Sun. The solar collector receives the Sun's rays and the retaining mechanism releases, at established intervals, allowing the frame to rotate to the next location. The cycle repeats, tracking the Sun and concentrating its rays at a focal point, to generate temperatures at the focal point in excess of 500° C. These high temperatures can be exploited in several applications, such as producing drinking water from dirty water; cooking food; disinfecting medical instruments; accelerating fermentation of certain types of flora to produce electricity; generating work for generic purposes; etc.

  • Patent number: 10564183
    Abstract: An inclination correcting processor performs an image process for correcting inclination of a surface image to a Z direction intersecting an X direction and a Y direction on the surface image of a sample which has been acquired from scanning by a scanning processor. The inclination correcting processor extracts a plurality of pixels from the surface image on a straight line along a predetermined direction and corrects inclination of the surface image based on luminance of the extracted pixels. In a case where correction is performed on the surface image of the sample having a flat surface at least in the one direction (P direction) intersecting the X direction and the Y direction, the inclination correcting processor performs the image process such that the predetermined direction (a direction of a straight line 28) substantially matches the one direction (P direction).

  • Patent number: 10551577
    Abstract: Processes and apparatuses described herein reduce the manufacturing time, the cost of parts, and the cost of assembly per laser for photonic interconnects incorporated into computing systems. An output side of a laser assembly is placed against an input side of a silicon interposer (SiP) such that each pad in a plurality of pads positioned on the output side of the laser assembly is in contact with a respective solder bump that is also in contact with a corresponding pad positioned on the input side of the SiP. The laser assembly is configured to emit laser light from the output side into an input grating of the SiP. The solder bumps are heated to a liquid phase. Capillary forces of the solder bumps realign the laser assembly and the SiP while the solder bumps are in the liquid phase. The solder bumps are then allowed to cool.
