Patent number: 11995871Abstract: Systems and methods are described herein for repairing a block of pixels in image data that was encoding using a lossy type of compression. In one aspect, it may be determined that a first pixel block within a first frame of image data was encoded using lossy compression, where the first pixel block comprising a plurality of pixels. Next, it may be determined that the plurality of pixels in the first pixel block in a second frame of the image data are below a threshold difference as compared to the plurality of pixels within the first frame of the image data. Responsive to the determining, the first pixel block may be re-encoded in the second frame or a subsequent frame of the image data using lossless compression.Type: GrantFiled: November 30, 2020Date of Patent: May 28, 2024Assignee: Amazon Technologies, Inc.Inventors: Russell Allen Brown, Paolo Maggi, Paolo Angelo Angelo Borelli, Paul Hinks, Mark John Keller

Patent number: 11967118Abstract: Systems and methods are described herein for implementing a hybrid codec to compress and decompress image data using both lossy and lossless compression. In one example encoding process, it may be determined whether a first block of pixels of a frame of image data contains an edge. A type of compression by which to encode the first block may be selected based on that determination. The first block may be compressed using the selected type of compression. At least one second value associated with the first block of pixels may be set to indicate at least oof the compressed value or the type of compression used to compress the first block.Type: GrantFiled: November 30, 2020Date of Patent: April 23, 2024Assignee: Amazon Technologies, Inc.Inventors: Russell Allen Brown, Paolo Maggi, Paolo Angelo Angelo Borelli, Paul Hinks, Mark John Keller

Patent number: 8022133Abstract: It is possible to improve significantly the optical performance of diacetal or DBS-based nucleating or clarifying agents using a co-additive. Haze is a measure of the lack of clarity in a thermoplastic or plastic material. A low level of haze is usually quite desirable, and nucleating/clarifying agents are designed to reduce the degree of haze in a plastic or thermoplastic material. A co-additive may be used in connection with a nucleating/clarifying agents in a polymer or copolymer to achieve even greater results in terms of improved clarity (reduced haze), or in terms of a higher crystallization temperature (Tc) of the polymer. A method for reducing haze in polymer articles using a co-additive composition in addition to nucleating and clarifying agents is disclosed.Type: GrantFiled: January 28, 2005Date of Patent: September 20, 2011Assignee: Milliken & CompanyInventors: Jiannong Xu, Jiang Li, Benjamin W. Bolt, Kemper David Lake, Jr., Jason Dean Sprinkle, Brian Michael Burkhart, Keith Allen Keller

Patent number: 7950234Abstract: Aspects of the invention are directed to a ring seal segment having a base portion and a frame portion. The base portion and the frame portion are a unitary structure. The frame portion is made of four unitary side walls: a forward wall, an aft wall and a pair of transverse side walls. The side walls can be arranged in a rectangular configuration. At least a part of the base portion can be coated with a thermal insulating material. A ring seal segment according to aspects of the invention is well suited to withstand the expected operational loads in the turbine section. The transverse side walls can provide bending strength to the base and can strengthen the forward and aft side walls. Transition regions between the side walls and the base portion are strengthened by three perpendicular planes that cooperate to provide structural strength to the ring seal segment.Type: GrantFiled: October 13, 2006Date of Patent: May 31, 2011Assignee: Siemens Energy, Inc.Inventors: David Charles Radonovich, Douglas Allen Keller, Jay Alan Morrison, Malberto Fernandez Gonzalez, Anthony L. Schiavo

Patent number: 7247003Abstract: A stacked ceramic matrix composite lamellate assembly (10) including shear force bearing structures (48) for resisting relative sliding movement between adjacent lamellae. The shear force bearing structures may take the form of a cross-lamellar stitch (50), a shear pin (62), a warp (90) in the lamellae, a tongue (104) and groove (98) structure, or an inter-lamellar sealing member (112), in various embodiments. Each shear force bearing structure secures a subset of the lamellae, with at least one lamella being common between adjacent subsets in order to secure the entire assembly.Type: GrantFiled: January 7, 2005Date of Patent: July 24, 2007Assignee: Siemens Power Generation, Inc.Inventors: Michael A. Burke, Jay A. Morrison, Steven James Vance, Daniel G. Thompson, Vijay Parthasarathy, Gary B. Merrill, Douglas Allen Keller

Patent number: 7124591Abstract: A gas turbine includes a compressor, a combustor, a turbine, and a flow path diverting an excess portion of the compressed air produced by the compressor around the turbine. The flow path conducts the excess portion into a turbine exhaust gas flow producing a cooled exhaust gas. A method of operating the gas turbine includes opening an inlet guide vane of the compressor to allow the compressor to produce an increased volume of compressed air. The increased volume exceeds a volume of compressed air needed to support combustion. An excess portion of the compressed air is directed into the exhaust gas to produce a cooled exhaust. In a combined cycle power plant, the cooled exhaust from the gas turbine may be used to warm a steam turbine portion to a desired temperature while allowing operation of the gas turbine at a power level that produces exhaust gas at a temperature higher than the desired temperature.Type: GrantFiled: January 9, 2004Date of Patent: October 24, 2006Assignee: Siemens Power Generation, Inc.Inventors: Joan Mae Baer, Walter Ray Laster, Douglas Allen Keller
