Publication number: 20240118914Abstract: An L2 virtual machine (VM) operating in a trust domain invokes a memory operation involving a virtual I/O device passed through from an L1 VM. Invocation of the memory operation causes an L2 virtual I/O device driver to make a hypercall to a trust domain management module. The hypercall comprises a memory-mapped I/O (MMIO) address of the virtual I/O device as seen by the L2 VM (L2 MMIO address), which matches the MMIO address of the virtual I/O device as seen by the L1 VM. The module passes hypercall information to an LO hypervisor, which forwards the information to an emulator operating in LO user space that emulates the back end of the virtual I/O device operating on the L1 VM. The emulator determines an emulated software response based on the L2 MMIO address and the memory operation is carried out.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Inventors: Chuanxiao Dong, I-Chun Fang, Yanting Jiang

Patent number: 11430586Abstract: Disclosed in the present invention is a post insulator, comprising a hollow insulating tube, a shed positioned on a periphery of the hollow insulating tube, and an upper flange and a lower flange provided at two ends of the hollow insulating tube, wherein gas is sealed inside of the hollow insulating tube, and the absolute pressure of the gas is 0.1-0.15 MPa. Further disclosed is an insulated support post formed by the end-to-end connection of the post insulators. The post insulator and the insulated support post of the present invention solve an interface problem present in internal insulating solid material filling, and also solve a gas leaking problem that occurs when using high-pressure gas filling, such that the post insulator does not need to be detected and maintained. At the same time, the margin of the micro-water control range is improved, and micro-water control and production difficulty is reduced.Type: GrantFiled: January 31, 2019Date of Patent: August 30, 2022Assignee: JIANGSU SHEMAR ELECTRIC CO., LTD.Inventors: Bin Ma, Jiang Fang, Chao Liu, Jie Yu, Guiyan Ni

Patent number: 11421437Abstract: A composite crossarm fixed on a pole body of a transmission pole is disclosed. The composite crossarm includes: a core rod, an insulating layer and a load-bearing member. The insulating layer and the load-bearing member cover and are fixed to an outer peripheral surface of the core rod. The load-bearing member is positioned in a middle region of the core rod connected to the pole body, and the insulating layer is positioned in regions of the core rod other than the middle region. A transmission pole using the above composite crossarm is also disclosed. In the above manner, the load-bearing member is arranged at a position where the core rod is connected to the pole body in advance. On one hand, the core rod is able to be connected to the pole body without providing with a hole. On the other hand, the load caused by the fixed connection is applied on the load-bearing member directly, with no damage to the insulating layer.Type: GrantFiled: May 17, 2018Date of Patent: August 23, 2022Assignee: JIANGSU SHEMAR ELECTRIC CO., LTD.Inventors: Bin Ma, Jie Yu, Dequan Li, Jiang Fang

Patent number: 11322923Abstract: An overhead power distribution line (10) comprises a tension resistant pole (101), two composite crossbeams (102) and tension resistant fixing members (103). A middle portion of the composite crossbeam (102) is horizontally secured on the tension resistant pole (101), and end portions of the composite crossbeam (102) are connected to the tension resistant fixing members (103). The tension resistant fixing members (103) enable the two composite crossbeams (102) to integrally connect and are for fixing conducting lines. With the above configuration, two composite crossbeams (102) are secured on the same horizontal plane of the tension resistant pole (101), thus satisfying vertical tension of a tension resistant requirement. Further, by using composited crossbeam bodies (102), a dry arc distance is significantly increased, and electrical lightning resistance performance is enhanced, preventing incidents such as line disconnection and flashover caused by lightning strike.Type: GrantFiled: September 29, 2018Date of Patent: May 3, 2022Assignee: JIANGSU SHEMAR ELECTRIC CO., LTD.Inventors: Bin Ma, Dequan Li, Jie Yu, Jiang Fang, Qing Huang
