Patent number: 11902525Abstract: Techniques and tools for encoding enhancement layer video with quantization that varies spatially and/or between color channels are presented, along with corresponding decoding techniques and tools. For example, an encoding tool determines whether quantization varies spatially over a picture, and the tool also determines whether quantization varies between color channels in the picture. The tool signals quantization parameters for macroblocks in the picture in an encoded bit stream. In some implementations, to signal the quantization parameters, the tool predicts the quantization parameters, and the quantization parameters are signaled with reference to the predicted quantization parameters. A decoding tool receives the encoded bit stream, predicts the quantization parameters, and uses the signaled information to determine the quantization parameters for the macroblocks of the enhancement layer video. The decoding tool performs inverse quantization that can vary spatially and/or between color channels.Type: GrantFiled: November 4, 2022Date of Patent: February 13, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Shankar Regunathan, Shijun Sun, Chengjie Tu, Chih-Lung Lin

Patent number: 11756755Abstract: A dual energy storage operating mechanism of an isolating switch is provided. A first energy storage mechanism and a second energy storage mechanism are provided between an input wheel and a housing and between the input wheel and an output wheel or a first output shaft, respectively. The output wheel is provided with a limiting mechanism. The limiting mechanism forms a locking effect on the output wheel when the first energy storage mechanism stores energy, thereby enabling the second energy storage mechanism to store energy at the same time. When the first energy storage mechanism starts to release energy, the locking effect of the limiting mechanism is released, so that the output wheel and the first output shaft can rotate, and the first energy storage mechanism and the second energy storage mechanism release energy at the same time, forming a dual energy storage boosting effect.Type: GrantFiled: July 12, 2019Date of Patent: September 12, 2023Assignee: ZHEJIANG BENYI ELECTRICAL CO., LTD.Inventors: Jianyong Huang, Renyuan Wang, Laiyuan Yu, Shijun Sun

Publication number: 20230245791Abstract: An introduction of nuclear fusion into conventionally fission-based nuclear reactors. Particularly, coolant in the reactor serves as the secondary fuel that absorbs neutrons from the fission core, and releases energy through fusion reactions. Molten Lithium is the preferred coolant in the invention, as it produces Helium gas through the neutron-Lithium fusion without leaving any radioactive or chemical impact to the environment. A Helium pressure controller is also introduced in the system to manage the Helium gas produced by nuclear reactions of the secondary fuel. Lithium Chloride (LiCl) is proposed as the secondary coolant in lieu of the commonly used molten salt in order to achieve higher power production efficiency. A reactor based on the proposed system requires less space than a conventional reactor of the same power. It is a better choice than conventional nuclear reactors when space is a key constraint, for example, on a container ship.Type: ApplicationFiled: January 29, 2022Publication date: August 3, 2023Inventors: Shijun Sun, Daniel Sun

Patent number: 10250905Abstract: Techniques and tools for conversion operations between modules in a scalable video encoding tool or scalable video decoding tool are described. For example, given reconstructed base layer video in a low resolution format (e.g., 4:2:0 video with 8 bits per sample) an encoding tool and decoding tool adaptively filter the reconstructed base layer video and upsample its sample values to a higher sample depth (e.g., 10 bits per sample). The tools also adaptively scale chroma samples to a higher chroma sampling rate (e.g., 4:2:2). The adaptive filtering and chroma scaling help reduce energy in inter-layer residual video by making the reconstructed base layer video closer to input video, which typically makes compression of the inter-layer residual video more efficient. The encoding tool also remaps sample values of the inter-layer residual video to adjust dynamic range before encoding, and the decoding tool performs inverse remapping after decoding.Type: GrantFiled: January 12, 2017Date of Patent: April 2, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Shijun Sun, Shankar Regunathan, Chengjie Tu, Chih-Lung Lin
