Patent number: 11973340Abstract: A line current iM(k0) of an M side of a first direct-current transmission line is collected at a moment k0. A line current iM(k0?ts) thereof is collected at k0?ts. At a moment k0, a differential value diM(k0) of a current of the side of the first direct-current transmission line is calculated according to the line current iM(k0) and the line current iM(k0?ts). It is determined whether the differential value diM(k0) of the current meets a protection enabling criteria. If so, direct-current protection for the M side of the first direct-current transmission line is enabled. A line current iM(j) of the M side of the first direct-current transmission line is collected at a moment j. A line current iM(j?ts) thereof is collected at a moment j?ts. A differential value diM(j) of the current of the M side of the first direct-current transmission line at the moment j is calculated according to the line current iM(j) and the line current iM(j?ts).Type: GrantFiled: June 18, 2020Date of Patent: April 30, 2024Assignees: CHINA ELECTRIC POWER RESEARCH INSTITUTE, STATE GRID CORPORATION OF CHINAInventors: Zexin Zhou, Huanzhang Liu, Pengfei Lv, Hong Cao, Xingguo Wang, Siye Ruan, Dingxiang Du, Yong Li, Guosheng Yang, Mingliang Jin

Patent number: 11931752Abstract: A non-contact precision pneumatic injection valve includes a cylinder, a needle disposed inside the cylinder, and an adjustable stroke limiting component. The adjustable stroke limiting component includes a thread-toothed column threadedly engaging an upper end of the cylinder; a spring-limiting column disposed inside and fixedly attached to the thread-toothed column, the spring-limiting column having a first protrusion ring; a spring column axially movably disposed inside the spring-limiting column and having a second protrusion ring, a lower end of the spring column defining a stroke of the needle; and a spring. One end of the spring fixedly engages the first protrusion ring and the other end of the spring fixedly engages the second protrusion so that the spring keeps the spring column at least partially inside the spring-limiting column. The spring biases the lower end of the spring column toward the needle.Type: GrantFiled: October 18, 2021Date of Patent: March 19, 2024Assignee: Suzhou Hsen-mez Automation Co., Ltd.Inventors: Xingguo Wu, Gang Li

Publication number: 20240083192Abstract: The instant disclosure is directed to a heterogeneous fiber fluid reservoir for holding and delivering fluid. A reservoir may comprise a rod having a core component and a surrounding component. Each of the core component and the surrounding component may comprise fibers. The core component may have a first property, and the surrounding component may have a second property different from the first property, or the core component and the surrounding component may each have a different value or range of values for the same property. Alternatively, a reservoir may comprise a rod that includes fibers and has a cross-sectional diameter. At least one property of the rod may vary in value along the cross-sectional diameter of the rod. The property may include, for example, fiber bulk density, fiber diameter, fiber material, fiber morphology, fiber surface tension, capillary force, fluid absorption capacity, color, or combinations thereof.Type: ApplicationFiled: November 22, 2023Publication date: March 14, 2024Applicant: Porex Technologies CorporationInventors: David Bradley HARRIS, Kevin SPORRER, Janie WIERZBICKI, Ronald Eugene BILLUPS, Yelena ROGOVA, Thomas E.
