Publication number: 20240115837Abstract: A delivery guidewire (100), comprising: a core wire (110) comprising a first segment (111), a second segment (112) and a third segment (113), which are arranged in sequence and have diameters decreasing in the direction from a distal end to a proximal end of the delivery guidewire (100); a metal ring (130) at least partially disposed at a proximal end of the first segment (111); and a spring (120) at least partially disposed over the outer side of the second segment (112). A distal end of the spring (120) abuts against a proximal end of the metal ring (130), and a distal section of the spring (120) has a diameter smaller than a diameter of a proximal section thereof. The diameter of the distal section of the spring (120) that is smaller than the diameter of the proximal section of the spring (120) results in a smaller clearance between the distal section of the spring (120) and the core wire (110), which enables greater concentricity of the distal section of the spring (120) with the core wire (110).Type: ApplicationFiled: December 28, 2021Publication date: April 11, 2024Inventors: Yafei CUI, Ziang LIU, Hanyi ZHAO, Haiying QIAO, Hao TIAN

Publication number: 20230417307Abstract: A muscle-like actuator comprises a motor with a rotatable drive shaft and a string with a shear thickening fluid (STF) embedded therein. One end of the string is attached to the drive shaft and the other end is connected to a load to form a twisted string actuator (TSA). By controlling the speed and current of the motor, the characteristics of the actuator can be changed. Multiple strings may be located in a flexible soft tube to improve the mechanical properties of the actuator.Type: ApplicationFiled: June 26, 2023Publication date: December 28, 2023Applicant: The University of Hong KongInventors: Ning XI, Qingqing ZHANG, Yafei ZHAO

Patent number: 11210169Abstract: Data storage method, apparatus, and system are disclosed. The data storage method includes: encoding a data block using an erasure coding to obtain corresponding multiple data fragments; separately writing the multiple data fragments to corresponding allocated storage nodes; and determining that writing of the data block is successful if a number of storage nodes to which data fragments is successfully written within a first defined time duration is greater than or equal to a defined value, wherein the defined value is greater than or equal to a number of data block fragments in the multiple data fragments and is less than or equal to a number of the multiple data fragments. As such, the latency of a data write can be reduced, and the performance stability can be improved when a storage node encounters a failure.Type: GrantFiled: July 7, 2020Date of Patent: December 28, 2021Assignee: Alibaba Group Holding LimitedInventors: Yuanyuan Dong, Shuzhan Wei, Yafei Zhao

Patent number: 9208100Abstract: The present invention provides a directory replacement method and device. An HA receives a data access request including a first address from a first CA, if a designated storage where a directory is located is entirely occupied by the directory, and a first directory entry corresponding to the first address is not in the directory, the HA selects a second directory entry from the directory, deletes it and adds the first directory entry into the directory; before the HA replaces the directory entry in the directory, no matter what status (for example, I status, S status or A status) a share status of a cache line corresponding to an address in the directory entry to be replaced is, the HA does not need to request a corresponding CA to perform an invalidating operation on data, but directly replaces the directory entry in the directory, thereby improving replacement efficiency.Type: GrantFiled: November 21, 2012Date of Patent: December 8, 2015Assignee: Huawei Technologies Co., Ltd.Inventors: Ce Yao, Yafei Zhao, Jianrong Xu
