Publication number: 20240133975Abstract: A computerized simulation validating method for a full-scale distribution network single phase-to-ground fault test is implemented by simulating a full-scale test system with external quantities being controlled to be conformant and validating the full-scale distribution network single phase-to-ground fault test based on a conformance check result between the internal quantities of the field testing and the internal quantities of the simulation testing. The simulation validating method for a full-scale distribution network single phase-to-ground fault test improves normalization and conformance of the full-scale distribution network ground fault test. The computerized simulation validating system, apparatus, and medium for a full-scale distribution network single phase-to-ground fault test also achieve the benefits noted above.Type: ApplicationFiled: August 10, 2023Publication date: April 25, 2024Inventors: Zhi LI, Shaofeng YU, Dingfang KE, Peibo WANG, Kan SUN, Weiqiang LANG, Haijiang XU, Kelong WANG, Zhiyong LI, Kun YU, Guangyao YING, Xuqiang HE, Yezhao CHEN, Xiang ZHANG, Mingxiao DU, Huijuan GUI, Hongling HU, Biao PENG, Xubin XIAO

Patent number: 11283247Abstract: A carrier mechanism for walking on a line includes a carrier platform constituted by a first mounting plate, a second mounting plate and a longitudinal movable plate, a walking apparatus, a clamping apparatus, a driving apparatus, and a self-balance control apparatus configured to adjust a posture of the carrier mechanism. The longitudinal movable plate is slidably arranged on the second mounting plate fixedly connected to the first mounting plate in parallel. The walking apparatus includes at least two sets of walking wheels arranged along a walking direction. The clamping apparatus is slidably arranged on the lower side of the longitudinal movable plate. The driving apparatus includes a first driving apparatus configured to drive the walking wheels to roll, and a second driving apparatus configured to drive the longitudinal movable plate to move. The clamping apparatus is driven by the longitudinal movable plate to clamp or release a to-be-inspected target.Type: GrantFiled: November 12, 2019Date of Patent: March 22, 2022Assignee: INSTITUTE OF AUTOMATION, CHINESE ACADEMY OF SCIENCESInventors: Guodong Yang, Xiaoyu Long, Weiqing Zhao, En Li, Zize Liang, Fengshui Jing, Han Wang, Hao Wang, Zishu Gao, Yunong Tian, Yuansong Sun, Sixi Lu, Guangyao Xu

Patent number: 10849650Abstract: A combined imaging probe holder and interventional needle guide assembly is provided. The imaging probe holder supports an imaging device (e.g., ultrasound probe) in a known relationship with a biopsy/treatment device holder such that a delivery element or interventional needle is constrained within an imaging field of the imaging device. Constraining the biopsy treatment device within the imaging field allows for real-time monitoring of the biopsy/treatment device during insertion of the interventional needle into patient tissue. In addition, the biopsy/treatment device holder is angularly positionable relative to the image field to allow advancement of the delivery element to any desired location within the imaging field.Type: GrantFiled: July 6, 2016Date of Patent: December 1, 2020Inventors: Guangyao Xu, Rajesh Venkataraman, Saradwata Sarkar, Michael Ahmadi

Patent number: 8494790Abstract: A system and method for detecting structural damage is provided that utilizes a general order perturbation methodology involving multiple perturbation parameters. The perturbation methodology is used iteratively in conjunction with an optimization method to identify the stiffness parameters of structures using natural frequencies and/or mode shape information. The stiffness parameters are then used to determine the location and extent of damage in a structure. A novel stochastic model is developed to model the random impact series produced manually or to generate a random impact series in a random impact device. The random impact series method or the random impact device can be used to excite a structure and generate vibration information used to obtain the stiffness parameters of the structure. The method or the device can also just be used for modal testing purposes. The random impact device is a high energy, random, and high signal-to-noise ratio system.Type: GrantFiled: May 16, 2008Date of Patent: July 23, 2013Assignee: University of Maryland, Baltimore CountyInventors: Weidong Zhu, Guangyao Xu, Chun Nam Wong, Nengan Zheng, Benjamin Haynes Emory

Patent number: 8278913Abstract: An improved apparatus and method for position sensing of a medical tracker device are presented. The apparatus and method are designed to constrain, rotate, and track the position of a medical tool. To improve the position sensing of the tracker, a joint that provides two degrees of freedom may use a revolute gear pair together with a rotary sensor for angular motion sensing and a sliding/prismatic assembly together with a linear magnetic sensor for linear position sensing. Thus, the linear motion sensing and the angular motion sensing are decoupled.Type: GrantFiled: May 15, 2009Date of Patent: October 2, 2012Assignee: Eigen Inc.Inventors: Dinesh Kumar, Guangyao Xu, Jasjit S. Suri
