Patent number: 12221888Abstract: A ventilation method for a high gas working face based on alternating intake and air return in a mine gallery is provided. In this method, an isolated island working face is divided into several sections along a strike direction. A coal pillar is alternately set as a conventional section and a gas-drainage section. Opposite coal pillars in the two mine galleries within the same section are respectively used as the conventional section and the gas-drainage section. Two mine galleries on both sides of the isolated island working face are alternately used as an intake gallery and a return gallery. The coal pillar at the side of the mine gallery as the return gallery is the gas-drainage section. A gas-drainage hole communicating a goaf is provided in the gas-drainage section, so that gas in the goafs at two sides of the isolated island working face can be extracted alternately.Type: GrantFiled: September 13, 2024Date of Patent: February 11, 2025Assignee: Taiyuan University of TechnologyInventors: Guorui Feng, Zhu Li, Jianyu Fan, Jingyu Zhang, Chengen Qi, Guilin Wu

Publication number: 20230401974Abstract: A method suitable for driver takeover training of man-machine shared driving vehicle relates to the field of man-machine shared driving technology. The method includes: establishing database, situation-creation, establish a teaching model, take over training, evaluation and analysis of takeover ability. The method divides the driver's takeover behavior into a small operation action through the driver takeover training of the man-machine shared driving vehicle, defines where the driver's eyes need to observe when the takeover reminder appears, how the hands and feet need to be operated, and the sequence of these operations, solves the problems of the driver's tension and being in a flurry in the current sudden takeover reminder. In addition, through the evaluation and analysis of the takeover capability, the method can solve the problem that the existing technology cannot objectively evaluate the driver's takeover capability level.Type: ApplicationFiled: June 14, 2023Publication date: December 14, 2023Applicants: Hefei University of Technology, Intelligent Manufacturing Institute of HFUTInventors: Zhongxiang FENG, Ya GAO, Zeyang CHENG, Lei ZHANG, Zhipeng HUANG, Jiabin ZENG, Jingyu LI, Yubing ZHENG, Dianchen ZHU, Weihua ZHANG, Kang JIANG

Publication number: 20200219189Abstract: A JYB-based barter transaction platform where trades between sellers and buyers are denominated in JYB is used to settle all objects and services purchased or sold on the platform. The JYB is a trade measuring currency instead of a circulation currency, and cannot be directly exchanged with a circulation currency. Only when the amount of JYB is insufficient during a trade, can the JYB difference be supplemented by a circulation currency at the conversion rate; in the case of regular settlement of circulation currency, the barter transaction platform collects the amount of circulation currency that has been received and refunded to users by the conversion rate. JYB can replace any circulation currency to achieve real-time barter trade.Type: ApplicationFiled: April 27, 2016Publication date: July 9, 2020Applicant: Global Prestige Information Technology Co., Ltd.Inventors: Jun LI, Jingyu LI
