Patent number: 10469706Abstract: A copy-evident document and a method of printing a copy-evident document wherein a void pantograph is created including a first set of halftone elements and a second set of halftone elements different in modulation from the first set of halftone elements. An overlay including a white image with a plurality of halftone hole locations is preferably formed, wherein the halftone elements of the void pantograph are converted to the plurality of halftone hole locations. The overlay is then preferably merged with a background image, such that portions of the background image are visible at the halftone hole locations of the overlay when printed. The merged image is then printed on print media, wherein the portions of the background image that are printed are printed at locations where the holes locations are present in the overlay creating a copy-evident feature.Type: GrantFiled: September 28, 2018Date of Patent: November 5, 2019Assignee: HAM LTDInventors: Judy Wailing Wu, Gregory Richard Wolfe

Publication number: 20140139002Abstract: The invention is directed to a method and article made from co-injection molding using gas-assist. The article has an inner material and an outer material. The inner material has a blowing agent uniformly distributed throughout the inner material. The outer material surrounds the inner material. At least one opening is provided in the outer material. The opening extends through the outer material to the inner material providing a pathway which allows out gas generated by the blowing agent in the inner material to escape through the outer material when the article is in a mold and after the article has been removed from the mold. The outer material provides an aesthetically pleasing outer surface and the inner material provides a strong core which is free of large voids, the inner and outer materials combining to form an article with a stable profile and repeatable size.Type: ApplicationFiled: January 24, 2014Publication date: May 22, 2014Applicant: KNOLL, INC.Inventors: Adam Daniel DESKEVICH, Hendrik Richard VAN HEKKEN, Richard A.

Patent number: 8663514Abstract: The invention is directed to an article made from co-injection molding using gas-assist. The article has an inner material and an outer material. The inner material has a blowing agent uniformly distributed throughout the inner material. The outer material surrounds the inner material. The use of the blowing agent in the inner material produces a repeatable and consistent structure, as the blowing agent is uniformly activated through the product. The use of the gas-assist the heat and pressure associated with the blowing agent is allowed to out gas, thereby insuring that the finished molded chair or other item is aesthetically pleasing while providing increased strength and reduced weight compared to traditional plastic chairs formed with known methods.Type: GrantFiled: May 10, 2011Date of Patent: March 4, 2014Assignee: Knoll, Inc.Inventors: Adam Daniel Deskevich, Hendrik Richard Van Hekken, Richard A.

Patent number: 8491121Abstract: An apparatus and method by which an image is projected to pupils of a viewer. Preferably, the image covers only areas occupied by the pupils and tracks the areas occupied by the pupils such as to provide continuous display of the imagery to a viewer. The method is to dynamically control the direction of light into sub-apertures selected by a tracking device. By imaging selectively into the sub-apertures where the pupils are temporally located instead of imaging into a generally large area, the disclosed apparatus is power efficient and exclusive because the projected images are covert. This method is applicable to most biocular displays, for instance, but not limited to “see through” systems, which overlay imagery over real world scenes and where geometrically precise projection is critical. In one embodiment, the pupil scan apparatus is combined with a retinal scan apparatus to provide security. In this manner, only an authorized user of the apparatus can operate it.Type: GrantFiled: October 7, 2008Date of Patent: July 23, 2013Assignee: Elbit Systems of America, LLCInventors: Michael M. Tilleman, Jonathan Everett, Richard Wolfe

Patent number: 8444828Abstract: A pyrolyzer and method is provided for devolatizing coal and other volatile materials. The pyrolyzer has a pyrolyzer furnace housing having at least two screws laterally positioned adjacent and overlapping rotatably mounted within the furnace for moving volatile material through the pyrolyzer furnace housing. The screws have hollow drive shafts with a diverter inside for converging heated fluid to heat the volatile material moving through the pyrolyzer furnace housing. A combustion chamber combusts fuel to create heated exhaust gas for directing through the hollow drive shafts to heat the volatile material. The pyrolyzer furnace housing may have a double wall with a cavity between, capable of receiving heated fluid for further heating of volatile material moving through the pyrolyzer furnace housing.Type: GrantFiled: December 19, 2007Date of Patent: May 21, 2013Assignee: Nucor CorporationInventor: Richard A.
