Patent number: 10605264Abstract: A diffuser, an airflow generating apparatus, and an electrical device are provided. The airflow generating apparatus includes a motor; an impeller including blades with air passages formed therebetween; and a diffuser including diffusing vanes with diffusing channels formed therebetween. In a flow region defined between a terminating end of one diffusing vane and a starting end of another adjacent diffusing vane, an intersection line between a bottom of the diffusing channel between the two diffusing vanes and its circumferential section includes a front arcuate line segment and a subsequent straight line segment, the arcuate line segment extends curvedly, outwardly and downwardly from or from adjacent an inlet end of the diffusing channel, the straight line segment connects to the arcuate line segment and extends to an outlet end of the diffusing channel. The diffusing channel is designed to improve the operating efficiency of the airflow generating apparatus.Type: GrantFiled: August 18, 2016Date of Patent: March 31, 2020Assignee: JOHNSON ELECTRIC INTERNATIONAL AGInventors: Chuan Hui Fang, Feng Xue, Hong Guang Li, Huan He

Patent number: 10598189Abstract: A fan of a vacuum cleaner includes a motor, an impeller, and a diffuser. The diffuser includes a bottom plate and guide vanes disposed on the bottom plate. The guide vanes are evenly spaced and arranged along a circumferential direction of the bottom plate. Each guide vane extends obliquely from an inner edge to an outer edge of the bottom plate. An outer end of each guide vane extends beyond the outer edge of the bottom plate. Each guide vane is deflected an angle of 30 to 70 degrees with respect to a tangential direction of the bottom plate at the inner end of the guide vane. The outer end of each guide vane is deflected an angle of 35 to 120 degrees along a circumferential direction with respect to the inner end of the guide vane.Type: GrantFiled: August 18, 2016Date of Patent: March 24, 2020Assignee: JOHNSON ELECTRIC INTERNATIONAL AGInventors: Feng Liu, Chuan Hui Fang, Feng Xue, Huan He

Publication number: 20170093652Abstract: A data visualization metrics explorer can be provided using JSON and hypertext. When an element of a grid row is selected, a new metrics explorer blade can be opened. A filter can be applied so that only information associated with the selected element is presented. Additional filters may also be applied to the data that is displayed. Progressive, iterative filtering can occur. The links between blades can be specified using JSON and hypertext. Multi-linking and re-use of individual JSON files can be performed by linking the JSON files together into a web. The web of visualization can be used to construct a web of visualization actions enabling data visualization exploration.Type: ApplicationFiled: September 28, 2015Publication date: March 30, 2017Inventors: Kevin Blasko, Ketan Ghelani, Patrick Tseng, Zhuming Pan, Haiying Xu, Divya Jayaraman, Huan He, Andrew Bragdon

Enabling efficient recovery from multiple failures together with one latent error in a storage array
Patent number: 9417963Abstract: The present invention provides a method and apparatus of managing a storage array. The method comprises: striping the storage array to form a plurality of stripes; selecting F storage chunks from each stripe as local parity chunks, and selecting another L storage chunks from the storage array as global parity chunks; performing (F+L) fault tolerant erasure coding on all data chunks in a stripe to generate (F+L) groups of parity data, and storing F groups of parity data therein into the F local parity chunks; performing cross-stripe operation on another L groups of parity data to generate L groups of global parity data, and storing them into the L global parity chunks, respectively. The apparatus corresponds to the method. With the invention, a plurality of errors in the storage array can be detected and/or recovered to improve fault tolerance and space utilization of the storage array.Type: GrantFiled: September 22, 2015Date of Patent: August 16, 2016Assignee: International Business Machines CorporationInventors: Huan He, Mingqiang Li -
