Publication number: 20210073973Abstract: Provided are a method and an apparatus for component fault detection based on an image, and a specific implementation is: when it is determined that an image shot by an image pickup apparatus for a component to be tested with a first shooting parameter does not meet a preset condition, adjusting the first shooting parameter to a second shooting parameter; controlling the image pickup apparatus to shoot for the component to be tested with the second shooting parameter to obtain a first image that meets the preset condition; and performing fault detection on the component to be tested according to the first image. The image pickup apparatus can be adjusted in real time, so that the image can be used for fault detection only when meeting the preset condition, thereby the image is kept stable, and the accuracy rate of component fault identification based on an image is improved.Type: ApplicationFiled: May 11, 2020Publication date: March 11, 2021Inventors: Jianfa ZOU, Ye SU, Minghao LIU, Lei NIE, Jiabing LENG, Yawei WEN, Tehui HUANG, Yulin XU, Jiangliang GUO, Xu LI

Patent number: 10171467Abstract: Example embodiments of the present disclosure provide methods, devices, and computer programs for authorization detection. The first system receives, from the second system unauthorized by the first system, a request for operating a resource of the first system. The first system causes a detection of an authorization chain to be detected based on the first record that at least indicates one or more systems that are authorized by the first system. The authorization chain includes at least a third system that authorizes the second system and is authorized by the first system. If the authorization chain is detected, the first system authorizes the operation of the resource of the first system.Type: GrantFiled: July 21, 2016Date of Patent: January 1, 2019Assignee: International Business Machines CorporationInventors: Lei Nie, Chun Lei Xu

Patent number: 9367585Abstract: A data storage and query method supporting an agile development and horizontal scaling, in a field of computer applications, includes steps of: transforming data into a 2-tuple (Key, MiniTable) and identifying any MiniTable (having a data set removed) with a unique Key, wherein the MiniTable includes multiple data columns; a structure of each data column is limited by a pre-defined mode; and the data columns are sorted according to a primary key defined by the mode. The data storage and query method obtains a capability of the horizontal scaling via removing dependency among the data sets, and a capability of the agile development via supporting an analogous SQL grammar by saving dependency among the data within the data sets. The data storage and query method can be applied to a data management system which supports the horizontal scaling of big data and the agile development of short development lifecycles.Type: GrantFiled: April 18, 2012Date of Patent: June 14, 2016Assignee: GUANGDONG ELECTRONICS INDUSTRY INSTITUTE LTD.Inventors: Lei Nie, Zhiwei Xu, Guojie Li, Jingjie Liu, Qiang Yue
