Patent number: 11927077Abstract: A high-frequency composite impactor including a high-frequency axial and a torsional impact assembly is disclosed. The high-frequency axial impact assembly includes an upper self-excited oscillation cavity, a lower self-excited oscillation cavity, an adjustment block and a lock nut. The torsional impact assembly includes an upper end cover, a reversing switch, a pendulum, a lower shell, a lower end cover, a nozzle, a connecting block and a retaining ring. The high-frequency axial impact assembly converts the flowing drilling fluid into a pulsed jet to achieve a high-frequency axial impact. The torsional impact assembly enables a torsional impact through a shunt, and finally enables a high-frequency composite impact, which can effectively reduce the stick-slip of the drill string, jump drilling and other downhole accidents. By reducing the friction between the drill string and the borehole wall, the impactor can reduce WOB loss, increase the ROP, and improve the drilling efficiency.Type: GrantFiled: September 26, 2022Date of Patent: March 12, 2024Assignees: Southwest Petroleum University, Sichuan Xieming Technology Co., Ltd.Inventors: Jialin Tian, Lanhui Mao, Yanniu Ren, Lin Yang, Haolin Song, Bo He, Jun Li, Lei Cha, Zhe Zhang, Yu Wei

Patent number: 11893257Abstract: A system may include a memory and a processor in communication with the memory configured to perform operations. The may operations include obtaining transaction logs in blocks from nodes of a data storage system. The operations may include, for each transaction log, splitting the transaction log into log entries, grouping log entries into groups associated with a same data source, and writing the log entries of the groups to empty blocks such that log entries from different groups do not share a same block. The operations may include identifying a same sequence of log entries from the written transaction logs and uploading first blocks of a first transaction log, including the same sequence of log entries, to an object-based storage without uploading second blocks of a second transaction log including the same sequence of log entries to the object-based storage.Type: GrantFiled: June 15, 2022Date of Patent: February 6, 2024Assignee: International Business Machines CorporationInventors: Peng Hui Jiang, FengLi Wang, Qi Feng Huo, Jun Su, Hong Qing Zhou, Yan Lin Ren, Li Zhang, Ling Ling Sh Hu

Patent number: 11822547Abstract: Shared materialized views are maintained during data changes to the primary data and during creation of new materialized views. Shared data stored for use by shared materialized views is distinguished from data stored by an independent materialized view. A view selector manages data updates to shared materialized views and corresponding mapping table. The view selector directs movement of data between a shared materialized view and an independent materialized view through the lifecycle of the materialized views.Type: GrantFiled: July 15, 2021Date of Patent: November 21, 2023Assignee: International Business Machines CorporationInventors: Peng Hui Jiang, Jun Su, Yan Lin Ren, Zhang Li, Hong Qing Zhou

Publication number: 20230301349Abstract: A cartridge for a vapour generating system, such as an e-cigarette, includes a vaporization chamber in which liquid is vaporized from a heater surface to mix with a flow of air through the vaporization chamber. Before reaching an air outlet, the airflow must pass through a restriction means such as a narrow neck, which helps to prevent droplets of re-condensed liquid leaking out of the air outlet. The restriction means also provides a convenient way to determine the distribution of air pressure along the airflow path and the overall resistance to draw of the vapour generating system.Type: ApplicationFiled: August 9, 2021Publication date: September 28, 2023Applicant: JT International SAInventor: Lin Ren Gu

Publication number: 20230292834Abstract: A cartridge for a vapour generating system, such as an e-cigarette, includes a vaporization chamber in which liquid is vaporized from a heater surface to mix with a flow of air through the vaporization chamber. An inlet channel between an air inlet and the vaporization chamber is convoluted such that it follows at least two directions transverse to the length of the cartridge and provides no straight path for condensed liquid in the vaporization chamber to leak back out of the air inlet. Because the inlet channel enters the vaporization chamber in a transverse direction, the airflow through the chamber is substantially parallel to the heater surface and promotes even vaporization of liquid across the whole area of the surface.Type: ApplicationFiled: August 9, 2021Publication date: September 21, 2023Applicant: JT International SAInventor: Lin Ren Gu

A processor retrieves, at the edge node, the at least one NFT from the received message. A processor validates, at the edge node, the received message based on the retrieved at least one NFT. A processor, responsive to validating the received message, forwards, by the edge node, the received message to a center node associated with the edge node.Type: ApplicationFiled: February 7, 2022Publication date: August 10, 2023Inventors: Qi Feng Huo, Xiang Dong Hu, Yan Lin Ren, Hong Qing Zhou, Peng Hui Jiang, Ling Ling SH Hu, Zhang Li
