Patent number: 7407288Abstract: Exemplary embodiments of the invention provide an eye-flow guiding level calculating system which can plan miniaturization and low cost of a device and surely obtain a suitable eye flow. A layout device, first, detects each vertex of an image object as guiding reference points, based on vector image data. And then, for every guiding reference point, two auxiliary lines are virtually formed to intersect the guiding reference point along an outline of the image object. Subsequently, the direction in which a bisector line of an obtuse angle among angles, made by the virtual auxiliary lines, extends outward from the guiding reference point is calculated as an eye-flow guiding direction. Further, for every guiding reference point, the distance from the center G of the image object up to the guiding reference point is calculated as an eye-flow guiding intensity. According to this construction, it is possible to quantitatively calculate in which direction the image object tends to guide the eye-flow.Type: GrantFiled: October 27, 2004Date of Patent: August 5, 2008Assignee: Seiko Epson CorporationInventors: Naoki Kayahara, Atsushi Nagahara

Patent number: 7407330Abstract: The present invention relates to a fiber optic connector holder sized to fit within an opening for mounting a fiber optic adapter. The fiber optic connector holder is configured to permit a fiber optic connector with a dust cap positioned about a ferrule and a polished end face of an optical fiber held by the ferrule to be inserted within and releasably held by the connector holder. The present invention further relates to a system for holding fiber optic connectors including a fiber optic connector holder mounted within an opening in a bulkhead for mounting a fiber optic adapter. The fiber optic connector holder is configured to receive a fiber optic connector with a dust cap mounted about a ferrule and polished end face of an optical fiber held by the ferrule. The present invention also relates to a method of holding an optical fiber connector to a bulkhead, when the fiber optic connector includes a dust cap mounted about a ferrule and a polished end face of an optical fiber held by the ferrule.Type: GrantFiled: March 27, 2007Date of Patent: August 5, 2008Assignee: ADC Telecommunications, Inc.Inventors: Trevor D. Smith, Thomas C. Tinucci, Cindy S. Walters, James W. Conroy, Joel B. Douglas, Kathleen M. Barnes, Marlon E. Holmquist

Patent number: 7407331Abstract: An optical branching module includes a case from which cables are drawn out and an output-cable fixing member attached onto the case by insertion. Optical cables are inserted into cable insertion holes of the optical cable fixing member, and the optical cables are fixed to the optical cable fixing member by an adhesive applied from an opening portion. The optical branching module includes a cable boot configured not to be bent in a radius of curvature smaller than the allowed radius of curvature of the optical cables.Type: GrantFiled: December 10, 2007Date of Patent: August 5, 2008Assignee: Fujikura Ltd.Inventors: Toshihiro Momotsu, Koichi Katayose

Patent number: 7407332Abstract: The present invention is to provide an intelligent pluggable transceiver improving an EMI tolerance with a simple mechanism. The optical transceiver of the invention comprises upper and lower housings (11, 12), a holder (81), optical assemblies (51, 61), a cover (14), a substrate (15) and a grip (13). The optical assemblies are fixed with the upper and lower housings together with the holder with interposing the conductive elastic member. Although the rear end of the substrate exposes outside the transceiver, the shield gasket and the ground pattern on the substrate shields the contact portion between the substrate and the upper housing and between the substrate and the cover. Moreover, the grip and the latch lever installed in the lower housing, and the elastic piece realize the latching/releasing mechanism of the transceiver with the host system.Type: GrantFiled: October 26, 2006Date of Patent: August 5, 2008Assignee: Sumitomo Electric Industries, Ltd.Inventors: Kazushige Oki, Hiromi Kurashima, Tomoyuki Funada, Shojiro Kiyotake, Kou Nito, Hiroshi Murata

Patent number: 7407333Abstract: An optical fiber fixing system includes a clamp base and a clamp member. The clamp base has a V-groove on a top surface thereof. The depth of the V-groove is configured such that a ridgeline of an optical fiber projects beyond the top surface of the base when the optical fiber is mounted therein. The clamp member has a protrusion on a bottom surface thereof. The protrusion depresses, from the upside, the optical fiber mounted in the V-groove of the clamp base. Further, the protrusion is configured to extend substantially perpendicularly to the axial direction of the optical fiber.Type: GrantFiled: March 12, 2004Date of Patent: August 5, 2008Assignee: Fujikura Ltd.Inventors: Seiji Horino, Kensuke Yoshida, Noriyuki Kawanishi

Patent number: 7407337Abstract: A locking positioning mechanism includes a first element and a second element, the first element and second element rotatable relative to one another about a common rotational axis between a locked orientation and an unlocked orientation and axially translatable relative to one another. The mechanism further includes one or more first locking surfaces of the first element and one or more second locking surfaces of the second element. The second locking surfaces are configured to clear the first locking surfaces in the unlocked orientation. The second locking surface is configured for an interference fit with a first locking surface in the locked orientation.Type: GrantFiled: June 17, 2004Date of Patent: August 5, 2008Assignee: Micron Technology, Inc.Inventors: Richard P.
