Patent number: 11842324Abstract: A method for extracting a dam emergency event based on a dual attention mechanism is provided. The method includes: performing data preprocessing, building a dependency graph, building a dual attention network, and filling a document-level argument. The performing data preprocessing includes labeling a dam emergency corpus and encoding sentences. Building a dependency graph includes assisting a model to mine a syntactic relation based on a dependency. Building a dual attention network includes weighing and fusing an attention network based on a graph transformer network (GTN) and capturing key semantic information in the sentence. Filling a document-level argument includes filling a document-level argument by detecting a key sentence and ordering a semantic similarity. The method introduces a dependency and overcomes the long-range dependency problem based on the dual attention mechanism, thus achieving high identification accuracy and reducing a lot of labor costs.Type: GrantFiled: October 14, 2022Date of Patent: December 12, 2023Assignees: HOHAI UNIVERSITY, HUANENG LANCANG RIVER HYDROPOWER INC., HUANENG GROUP TECH INNOVATION CENTER CO., LTD.Inventors: Yingchi Mao, Wei Sun, Haibin Xiao, Fudong Chi, Hao Chen, Weiyong Zhan, Fugang Zhao, Han Fang, Xiaofeng Zhou, Chunrui Zhang, Bin Tan, Wenming Xie, Bingbing Nie, Zhixiang Chen, Chunrui Yang

Publication number: 20230368500Abstract: A time-series image description method for dam defects based on local self-attention mechanism is provided, including: performing frame sampling on an input time-series image of dam defect, extracting a feature sequence using a convolutional neural network and using the sequence as an input to a self-attention encoder, where the encoder includes a Transformer network based on a variable self-attention mechanism that dynamically establishes contextual feature relations for each frame; generating description text using a long short term memory (LSTM) network based on a local attention mechanism to enable each word predicted to be feature related to an image frame, improving text generation accuracy by establishing a contextual dependency between image and text. A dynamic mechanism is added to the present application for calculating the global self-attention of image frames, and LSTM networks with added local attention directly establish the correspondence between image and text modal data.Type: ApplicationFiled: June 19, 2023Publication date: November 16, 2023Inventors: Hongqi Ma, Haibin Xiao, Yingchi Mao, Fudong Chi, Rongzhi Qi, Bohui Pang, Xiaofeng Zhou, Hao Chen, Jiyuan Yu, Huan Zhao

Patent number: 10483860Abstract: Various embodiments of devices, systems, and methods for regulating the output current of a switched mode, resonant power converter using primary side regulation. For at least one embodiment, a circuit for primary side regulation of a constant output current resonant transformer includes a transformer having a first coil with a first terminal and a second terminal. A controller circuit is configured to receive an input voltage and a resonant circuit is coupled to the controller circuit and the first terminal. A current sense circuit is coupled to the second terminal and to the controller circuit. The current sense circuit is configured to detect fluctuations in a sensed resulting voltage potential representative of the output current of the transformer. The current sense circuit is configured to provide a feedback signal to the controller circuit when the sensed resulting voltage potential is greater than a reference voltage.Type: GrantFiled: June 13, 2018Date of Patent: November 19, 2019Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Haibin Xiao, W K Chong
