Publication number: 20240076769Abstract: Red rust staining of Al/Zn coated steel strip in “acid rain” or “polluted” environments can be minimised by forming the coating as an Al—Zn—Si—Mg alloy coating with an OT:SDAS ratio greater than a value of 0.5:1, where OT is the overlay thickness on a surface of the strip and SDAS is the measure of the secondary dendrite arm spacing for the Al-rich alpha phase dendrites in the coating. Red rust staining in “acid rain” or “polluted” environments and corrosion at cut edges in marine environments can be minimised in Al—Zn—Si—Mg alloy coatings on steel strip by selection of the composition (principally Mg and Si) and solidification control (principally by cooling rate) and forming Mg2Si phase particles of a particular morphology in interdendritic channels.Type: ApplicationFiled: August 8, 2023Publication date: March 7, 2024Applicant: Bluescope Steel LimitedInventors: Ross McDowall SMITH, Qiyang LIU, Bryan Andrew SHEDDEN, Aaron Kiffer NEUFELD, Joe WILLIAMS, David James NOLAN, Wayne RENSHAW

Patent number: 9332271Abstract: A method, a device and computer readable storage media facilitate providing screen content including a plurality of video frames that are displayed by a computing device. During coding of the screen content, a suitable predictor is found that is used to code pixel blocks from one or more frames. The suitable predictor is found by selecting a pixel block of a current frame, conducting a direction based search by comparing pixel blocks within a search window of a reference frame with the selected pixel block of the current frame to determine whether a match exists, and, in response to a determination that no sufficient match has been found, conducting a feature oriented search by comparing pixel blocks of the reference frame with the selected pixel block of the current frame to find a suitable match based upon a common feature.Type: GrantFiled: March 30, 2012Date of Patent: May 3, 2016Assignee: Cisco Technology, Inc.Inventors: Sijia Chen, Kai Li, Wayne Liu, Siping Tao

Patent number: 9232244Abstract: Techniques are provided to improve user experience at endpoint devices that are participating in a multipoint screen content sharing session. A server in a multipoint communication system receives video frames from a sending endpoint device in the communication session that involves one or more other endpoint devices that are to receive video frames from the sending endpoint device. The video frames include key reference frames that use either intra-frame prediction or inter-frame prediction based only on other key reference frames. The server stores the key reference frames. When a new receiving endpoint device joins the communication session, the server sends all the stored key reference frames to the new receiving endpoint device. All video frames received from the sending endpoint device are forwarded to existing ordinary receiving endpoint devices. Key reference frames and some, but not all, non-key reference video frames are forwarded to existing low-capacity receiving endpoint devices.Type: GrantFiled: September 11, 2012Date of Patent: January 5, 2016Assignee: Cisco Technology, Inc.Inventors: Sijia Chen, Wayne Liu, Siping Tao

Patent number: 9172909Abstract: In one embodiment, video is transmitted between a sending device and a receiving device. The sending device is configured to receive adjacent camera views and encode the adjacent camera views independently into video streams. The sending device performs an image analysis on the adjacent camera views in order to generate a projection matrix to relate the adjacent camera views. The projection matrix and the encoded video streams are sent to at least one receiver. The receiver is configured to receive the encoded video streams and the projection matrix relating the encoded video streams. The receiver calculates an aggregate video stream using the projection matrix. The aggregate video stream includes portions of at least two of the encoded video streams. Other receivers may receive the same encoded video streams and generate a different aggregate video stream having a varying size, resolution, or number of views.Type: GrantFiled: October 29, 2013Date of Patent: October 27, 2015Assignee: Cisco Technology, Inc.Inventors: Guang Xu, Dong Zhang, Ling Zhu, Yongze Xu, Ling Zhang, Wayne Liu
