Publication number: 20240100658Abstract: A powered ratchet includes a motor, a mounting portion, and an output member configured to rotate in response to activation of the motor. The output member defines a drive axis. The powered ratchet also includes a release mechanism configured to selectively couple an anvil to the output member. The release mechanism includes a cover coupled to the mounting portion with a track and a locking member positioned between the mounting portion and the cover and operable to slide within the track between a locked position, in which the locking member engages the anvil to secure the anvil to the output member for co-rotation therewith, and a release position, in which the locking member is disengaged from the anvil to facilitate removal of the anvil. The release mechanism also includes a biasing member biasing the locking member to the locked position.Type: ApplicationFiled: February 18, 2022Publication date: March 28, 2024Inventors: Austin Clark, Carl N. Chandler, Matthew Samstag, Joshua Collins, James W. Jenkins, Ryan Altenburger, Gui Fang Zhou, Yu Zhao, Ping Zhang

Patent number: 9619334Abstract: A system divides a source computer storage device into a plurality of logical volumes, and creates a first recovery point data file and a first recovery point index file. In response to an incremental backup of a first logical volume, the system creates a second recovery point index file comprising a plurality of indices. In response to no data changing in a particular block in the first logical volume, the system points an index in the second recovery point index file to the particular block in the first logical volume. In response to data changing in the particular block in the first logical volume, the system creates a corresponding new block in a second recovery point data file. The system points the index in the second recovery point index file to the corresponding new block in the first logical volume.Type: GrantFiled: December 28, 2015Date of Patent: April 11, 2017Assignee: CA, Inc.Inventors: Austin Fang, Zhe He, Lei Li, Taiwen Zhang
