Publication number: 20080050083Abstract: There is provided a fiber optic housing assembly that includes a fiber optic interconnection portion and/or a splice portion. To provide the technician convenient access to the interconnection portion and/or the splice portion, the slidable shelf portion includes a pivotable portion that allows the interconnection portion and/or splice portion to be moved upwards or downwards, such as by pivoting about an axis. Therefore, the technician can preferably manipulate the fiber optic cables and/or connectors at an upper portion of the equipment rack without using a step ladder or similar device and at the lower portion of the equipment rack with greater comfort. The pivotable portion includes locks, latches, pins, and/or the like to prevent unintentional movement of the pivotable portion relative to the shelf portion and/or exterior portion of the housing assembly.Type: ApplicationFiled: August 25, 2006Publication date: February 28, 2008Inventors: Brent M. Frazier, Raymond G. Jay, Danny McGranahan, Craig A. Strause

Publication number: 20080050087Abstract: Fiberoptic luminaire with scattering and specular side-light extractor patterns comprises a fiberoptic light pipe with elongated side-light emitting portion. Such portion illuminates a target area with a scattering, and a specular, light extractor pattern. The extractor patterns are arranged to extract light from the side-light emitting portion over a radial angle, orthogonal to said main axis, of less than 180°. The scattering extractor pattern alone may provide greater than 50% of light on the target area, and light extracted by the specular extractor pattern alone may produce an illuminance on a selected portion of the target area that is greater than 5% of the maximum illuminance produced on the target area by the scattering extractor pattern. Furthermore, the scattering extractor pattern may comprise a Lambertian type of extractor pattern. Each specular extractor pattern may comprise a notch having main faces parallel to within 10° of each other.Type: ApplicationFiled: August 23, 2006Publication date: February 28, 2008Inventors: Roger F. Buelow, William J. Cassarly, Thomas L.R. Davenport, John M. Davenport, Chris H. Jenson

Publication number: 20080050088Abstract: A backlight includes a lightguide, a light source disposed with respect to the lightguide to introduce light into the lightguide and a turning film. Optical structures are formed in one of an output surface and a back surface of the lightguide. The optical structures are arranged to extract light from the lightguide. A back reflector is disposed adjacent the back surface. The optical structures are formed to include a varying pattern arranged to mask non-uniformities in the output of the lightguide.Type: ApplicationFiled: October 30, 2007Publication date: February 28, 2008Inventors: Mark Gardiner, Sanford Cobb, Kenneth Epstein, Wade Kretman

Publication number: 20080050089Abstract: A recording system includes a recording device, an information processing apparatus, a recording control unit, and an information processing control unit. The recording control unit manages data files recoded on first recording media and a second recording medium using a directory structure having directories of first recording media and a directory, serving as an entry folder, of the second recording medium under a root directory, selects, in response to a data file and an information file detailing category information being written in the entry folder, a first recording medium based on the category information, and controls the recording device to record the selected data file on the selected medium. The information processing control unit controls, in response to a data file and category information being specified, a writing operation so that the specified data file and the information file are written in the entry folder.Type: ApplicationFiled: August 17, 2007Publication date: February 28, 2008Applicant: Sony CorporationInventor: Satoshi MAEDA
