Patent number: 11924829Abstract: A signal reception apparatus and method and a communications system. As the starting position of the time domain resource section used for receiving signals is determined according to the predefined or preconfigured reference time domain resource section, time domain resources on which receiving beams determined by the network device and the terminal equipment are based are uniform, thereby avoiding mismatch of the network device and the terminal equipment in receiving and transmitting beams and ensuring transmission reliability of the system.Type: GrantFiled: June 11, 2020Date of Patent: March 5, 2024Assignee: FUJITSU LIMITEDInventors: Lei Song, Lei Zhang, Xin Wang, Zhe Chen, Guoyu Zhang

Publication number: 20230402121Abstract: Embodiments of the present disclosure provide a method for optimizing a flash memory chip and a related apparatus. The method comprises, after completing write training of a nonvolatile flash interface (NFI) and establishing a data strobe signal (DQS) trigger point that triggers a memory to identify an electrical level state of a write data signal (DQ) corresponding to the DQS trigger point, determining whether a trigger condition for monitoring the NFI is met, wherein the trigger condition is related to working environmental data of the NFI; upon determining that the trigger condition for monitoring the NFI is met, writing test data to the memory and performing a margin test on the NFI to determine whether the NFI passes a margin test; and upon determining that the NFI does not pass the margin test, initiating interface retraining of the NFI. In this way, the NFI bus channels can be optimized without disk disconnection.Type: ApplicationFiled: August 24, 2023Publication date: December 14, 2023Inventors: Jun YU, Guoyu WANG, You LI, Yongyao LI

Publication number: 20230211854Abstract: The amphibious unmanned patrol vehicle includes a buoy, a waterproof cable and a submersible amphibious vehicle. An end of the waterproof cable is connected to a first controller of the buoy; and another end thereof is connected to a second controller of the submersible amphibious vehicle. A bottom end of the buoy is connected to a top end of the submersible amphibious vehicle which is configured to realize movement and operation of a whole system. The waterproof cable is configured to connect the submersible amphibious vehicle, and the buoy configured to ensure real-time communication between the submersible amphibious vehicle and an external environment during operation of the submersible amphibious vehicle. A height difference between an upper surface and a lower surface of the automatic reeling and unreeling cable device is equal to a thickness of the waterproof cable. The length of the waterproof cable is adjusted automatically in real time.Type: ApplicationFiled: October 17, 2022Publication date: July 6, 2023Inventors: Tairan CHEN, Jiacheng CHEN, Zeyang LI, Haoran LIU, Biao HUANG, Guoyu WANG

Patent number: 11430494Abstract: A controller for data strobe signal (DQS) position adjustment includes, when the controller obtains margin effective widths of all data signals in a transmission bus, it determines a left boundary and a right boundary based on the margin effective widths, where the left boundary is a largest value in minimum values of the margin effective widths of all the DQs, and the right boundary is a smallest value in maximum values of the corresponding margin effective widths when all the DQs are aligned with the left boundary. The controller calculates a first central position based on the left boundary and the right boundary, where the first central position is a center of a smallest margin effective width obtained after all the DQs are aligned during read data training, and adjusts a delay line (DL) of the DQS to the first central position.Type: GrantFiled: November 13, 2020Date of Patent: August 30, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yongyao Li, Jun Yu, Guoyu Wang, Jiankang Li, You Li, Ruihui Hong
