Patent number: 11578824Abstract: A crimping tool is described comprising a first crimping member, a second crimping member, at least one intermediate crimping member, a first sliding member and a second sliding member. The free ends of the first crimping member and the second crimping member form an opening of the crimping tool. The first crimping member, the at least one intermediate crimping member, and the second crimping member are sequentially hinged together via connecting devices. The first sliding member is slidably disposed on the free end of the first crimping member. The second sliding member is slidably disposed on the free end of the second crimping member. The first sliding member is adjacent to the second sliding member. The inner sides of the first crimping member, the at least one intermediate crimping member, the second crimping member, the first sliding member, and the second sliding member are formed to be pressed with the workpiece to be crimped.Type: GrantFiled: May 13, 2020Date of Patent: February 14, 2023Assignee: Ridge Tool CompanyInventors: LeiHua Chen, Qi Zhou

Patent number: 11343213Abstract: A method for generating a reputation value of a sender includes: obtaining non-spam logs in a specified period; calculating an initial reputation value of a target sender according to sender identifications and recipient identifications of the non-spam logs as well as the number of emails sent by senders of the non-spam logs; calculating a transferred reputation value of the target sender according to the sender identifications of the non-spam logs and the number of the emails sent by the senders of the non-spam logs; and calculating a current reputation value of the target sender according to the initial reputation value and the transferred reputation value of the target sender. The method can accurately calculate the reputation value of the sender without relying on an email sending history of the sender, thereby effectively preventing the reputation value of the sender from being increased by cheating.Type: GrantFiled: July 9, 2020Date of Patent: May 24, 2022Assignee: LUNKR TECHNOLOGY (GUANGZHOU) CO., LTD.Inventors: Leihua Chen, Qingfeng Pan

Publication number: 20210199249Abstract: The present application discloses an LED flexible filament strip and an LED flexible lamp. Compared with the prior art, the light source is in the form of a flexible strip, realizing omnidirectional light emission through winding, so that various light colors can be more fully mixed and the problem of abrupt color lumps is avoided. The overall light distribution is more uniform, and a multi-angle light supplementing effect is realized, thus solving the problem that the back of a cuboid light source is opaque. Multiple dispersed light sources are concentrated on one flexible light filament, so that the number of solder joints for welding the positive and negative electrodes of the light source is reduced, and the risks of desoldering and faulty soldering are also reduced.Type: ApplicationFiled: June 12, 2020Publication date: July 1, 2021Inventors: Leihua CHEN, Qiaoming LIU

Patent number: 10759037Abstract: The present invention relates to a hydraulic tool including a working unit, a driving unit, a connection unit, and a switching device. The working unit is adapted to operate a workpiece. The driving unit is configured to drive the working unit and comprises a housing and a movable part provided in the housing and movable between an initial position and an end position. The connection unit connects the working unit and the driving unit. The switching device can rotate between a first position and a second position. When the switching device is in the first position, the movable part of the driving unit has a first stroke from the initial position to the end position; when the switching device is in the second position, the movable part of the driving unit has a second stroke smaller than the first stroke.Type: GrantFiled: February 24, 2017Date of Patent: September 1, 2020Assignee: RIDGE TOOL COMPANYInventors: Qi Zhou, Leihua Chen
