Publication number: 20240134840Abstract: This specification discloses example distributed table lock application methods and apparatuses, storage media, and electronic devices. In an example method, a master node receives a data processing request and determines a data table that to-be-processed data corresponding to the data processing request are located in. The master node generates a table lock for the data table; performs a lock operation on the data table and generates lock status information corresponding to the data table; writes the lock status information into a local log of the master node and synchronizes the log to a slave node such that the slave node stores the log. After the master node restarts, determines whether the master node stores the log; and in response to that the master node stores the log, restores the lock operation on the data table based on the lock status information recorded in the log.Type: ApplicationFiled: October 24, 2023Publication date: April 25, 2024Applicant: Beijing Oceanbase Technology Co., Ltd.Inventors: Fanyu Kong, Xiaofei Cui, Fusheng HAN, Ting Cao

Publication number: 20240076157Abstract: A coil replacing device. When a first unreeling assembly at an unreeling station finishes unreeling, a fixing suction member can be driven by a first driver abutting against a first suction member clamping a working material tape, a first cutting assembly cuts off the working material tape, and the cut working material tape is sucked by the fixing suction member. Then, a vertical plate slides to make a second unreeling assembly enter the unreeling station, a material tape sucked by a second suction member will also enter the unreeling station as a spare material tape, and the first unreeling assembly will be removed from the unreeling station. The fixing suction member is driven by the first driver to abut against the second suction member, so as to realize coil replacing, and the first unreeling assembly can be loaded with a new material tape to serve as a spare material tape.Type: ApplicationFiled: January 20, 2023Publication date: March 7, 2024Applicant: WUXI LEAD INTELLIGENT EQUIPMENT CO., LTD.Inventors: Er CAO, Xiaofei YANG

Publication number: 20240076156Abstract: A coil replacing device. Material tapes output by a first unreeling assembly and a second unreeling assembly can be alternately used as a working materials tape and a spare materials tape. When the unreeling of the working material tape by the first unreeling assembly is about to be finished, a first cutting assembly cuts off the working material tape fixed by a fixing mechanism and a first positioning assembly, and the spare material tape unreeled by the second unreeling assembly can be aligned with the working material tape fixed by the first positioning assembly. Then, a swing assembly drives an adhesive attaching driver to swing from an adhesive preparation position to an adhesive attaching position, and an adhesive attaching mechanism drives two suction plates to be folded, connecting the spare material tape with the working material tape to form a new working material tape.Type: ApplicationFiled: January 10, 2023Publication date: March 7, 2024Applicant: WUXI LEAD INTELLIGENT EQUIPMENT CO., LTD.Inventors: Xiaofei YANG, Er CAO

Publication number: 20240066640Abstract: A tab welding device, including a mounting base, a welding assembly, a swinging member and a driving assembly. The welding assembly is rotatably arranged on the mounting base. The swinging member is connected with the welding assembly. The driving assembly is provided with a moving end capable of reciprocating in a first direction, and the moving end is movably connected with the swinging member and is for driving the swinging member to swing to make the swinging member drive the welding assembly to rotate. With the tab welding device, the driving assembly drives the swinging member to swing, and the swinging member drives the welding assembly to rotate, so the angle of the welding assembly can be adjusted until the welding assembly is adjusted to an angle allowing a tab to be welded easily.Type: ApplicationFiled: December 30, 2022Publication date: February 29, 2024Applicant: WUXI LEAD INTELLIGENT EQUIPMENT CO., LTD.Inventors: Xiaofei YANG, Er CAO

Patent number: 9591471Abstract: A non-call service processing method, apparatus and system in a Circuit Switch Fallback (CSFB) system are provided. The method includes that UE transmits a location updating request to VLR2 where a new LAI is located; VLR2 receiving the location updating request transmits a location updating request to a HLR; the HLR receiving the location updating request transmits a location cancellation message carrying an address of VLR2 to VLR1 where original LAI is located; VLR1 receiving the location cancellation message forwards a received non-call service request to VLR2; VLR2 processes the received non-call service request, and transmits a processing result to VLR1; and VLR1 transmits the received processing result to the HLR or a GMLC which transmitted the non-call service request. Thus the interruption of a non-call service can be avoided, and the normal use of UE can be ensured.Type: GrantFiled: September 9, 2013Date of Patent: March 7, 2017Assignee: ZTE CORPORATIONInventors: Jingxiang Liu, Xiaofei Cao, Changle Zou

Publication number: 20150327050Abstract: A method, an apparatus, and a mobility management entity (MME) for processing a circuit switched network service are provided. The method for processing a circuit switched network service includes: the MME receives a request for processing a circuit switched network service; and the MME interacts with a user equipment (UE) corresponding to the request, and processes the circuit switched network service. The technical solution solves the problem in the prior art that the UE needs to fall back to the traditional circuit switched network so as to receive the circuit switched network service, thereby reducing the network consumption, enhancing the network efficiency, and improving the user experience.Type: ApplicationFiled: October 21, 2013Publication date: November 12, 2015Inventors: Jingxiang LIU, Xiaofei CAO, Lei YU

Patent number: 8660553Abstract: The invention provides a method for bypassing intelligent services of a called user, applied in the case that a GMSC and VMSC are not the same MSC. The method comprises: the GMSC sending information to the VMSC as to whether the intelligent services of the called user are bypassed in the GMSC; the VMSC determining whether the intelligent services are bypassed in the GMSC, and determining whether the intelligent services are bypassed in the VMSC; and when the VMSC determines that the intelligent services are bypassed in the GMSC and are not bypassed in the VMSC, the VMSC not triggering the intelligent services; when the VMSC determines that the intelligent services are not bypassed in the GMSC and are bypassed in the VMSC, the VMSC sending a call release message to the GMSC. The invention further provides a system and VMSC for bypassing intelligent services of a called user.Type: GrantFiled: May 21, 2010Date of Patent: February 25, 2014Assignee: ZTE CorporationInventors: Jianhong Chen, Xiaofei Cao
