Patent number: 9432616Abstract: Methods, systems, devices, and implementing technologies for up-scaling an original source video from a lower, first resolution to a desired output video having a higher, second resolution, using fractal zooming techniques to replace individual source pixels in each respective image frame of the original source video with a plurality of proposed replacement pixels in the vertical and horizontal dimensions having similar characteristics as the individual source pixel, reducing noise associated with each respective frame of the desired output video, re-sizing, as necessary, each respective replacement frame to the second resolution, and outputting each zoomed replacement frame to generate the desired output video, which is an up-scaled version of the original source video. The quality of the up-scaled output video is improved by using artifact filtering and linear smoothing techniques after the initial search and replace steps of the fractal zooming process.Type: GrantFiled: March 16, 2015Date of Patent: August 30, 2016Assignee: DIMENSION, INC.Inventors: Lyman P. Hurd, John H. Elton, Carlos M. Diaz-Perez

Patent number: 8983236Abstract: Methods, systems, and devices for up-scaling a source input video from a lower, first resolution to a desired output video having a higher, second resolution, using fractal zooming techniques to replace each individual source pixel of each respective frame of the source input video with a multiple of proposed replacement pixels in the vertical and horizontal dimensions having similar characteristics as the individual source pixel, reducing noise associated with each respective frame of the desired output video, re-sizing, as necessary, each respective replacement frame to the second resolution, and outputting each zoomed replacement frame to generate the desired output video having a higher, second resolution, which is the up-scaled version of the source video. The fractal zooming techniques include identifying a plurality of candidate pixels from the source video and selecting a group of pixels from the candidate pixels that best matches the individual source pixel.Type: GrantFiled: December 1, 2013Date of Patent: March 17, 2015Assignee: Dimension, Inc.Inventors: Lyman P. Hurd, John H. Elton, Carlos M. Diaz-Perez

Patent number: 6270554Abstract: A continuous nickel matte converter and method for the efficient production of low iron nickel-rich mattes from high-iron nickel-rich mattes, with minimal environmental impact. The present invention processes high-iron, nickel-rich primary furnace mattes to produce low iron, nickel-rich mattes, low value metal-containing slag and sulfur dioxide rich-off gas, with improved cobalt recovery. It eliminates use of the Peirce-Smith converter, with its undesirable environmental, metallurgical and economic features.Type: GrantFiled: March 14, 2000Date of Patent: August 7, 2001Assignee: Inco LimitedInventors: Paul E. Queneau, Carlos M. Diaz

Patent number: 5194213Abstract: A system for continuous smelting of sulfidic copper concentrate in which an oxygen flash furnace is operatively connected with a continuous converter and the continuous converter is operatively connected with a finishing furnace.Type: GrantFiled: April 28, 1992Date of Patent: March 16, 1993Assignee: Inco LimitedInventors: Carlos M. Diaz, Malcolm C. E. Bell

Patent number: 5178666Abstract: This invention relates to a thermal upgrading process whereby nickel-containing limonite or limonite/saprolite blends are pelletized with requisite amounts of solid carbon reductant and a sulfure-bearing concentrating agent. The pellets are fed to a reactor where they are gradually heated, causing reduction of the metal values. The reduced pellets are then held in a "metallics growth zone" of the reactor at a temperature high enough to allow for liquid-phase migration of the metallics within the pellets but below the point at which the pellets become sticky. The metallics growth zone is provided with a carefully controlled combustion gas atmosphere equivalent to about 60-65% aeration of partial combustion of natural gas which prevents further reduction or re-oxidation and thus provides a good environment for metallic particle growth. After a sufficient retention time, the pellets are then rapidly cooled to prevent the disproportionation of wustite to magnetite.Type: GrantFiled: December 3, 1991Date of Patent: January 12, 1993Assignee: Inco LimitedInventors: Carlos M. Diaz, Ahmed Vahed, Dingzhu Shi, Christopher D. Doyle, Anthony E. M. Warner, Douglas J. MacVicar

Patent number: 5112572Abstract: The invention provides a method for removing the oxide surface from water atomized metal powders containing an oxidizer capable of oxidizing chromium from a trivalent to a soluble hexavalent state, whereby chromium oxides are removed from the metal powder surface. The powder is then treated with a dilute acid solution essentially devoid of hydrofluoric acid to remove other hydrated oxides from the metal powder surface. The powder is then water washed and dried.Type: GrantFiled: October 1, 1991Date of Patent: May 12, 1992Assignee: Inco LimitedInventors: Thijs Eerkes, James A. E. Bell, Carlos M. Diaz

Patent number: 4836979Abstract: A method of producing a composite material from a mixture of copper and a low coefficient of thermal expansion nickel-iron alloy (Invar) powder is disclosed wherein advantageously at least part of the copper is deposited on the Invar powder prior to processing. Processing includes cold compacting to a green strip or other configuration, annealing in the temperature range of 550.degree.-750.degree. C. and working the annealed material at a temperature in that range to high density.Type: GrantFiled: June 14, 1988Date of Patent: June 6, 1989Assignee: Inco LimitedInventors: James A. E.
