Publication number: 20240073045Abstract: A blockchain-based data processing method, apparatus, and computer-readable medium are provided. Block proposal information is received including a block and a digital signature transmitted by an out-block node. The digital signature is obtained by performing digital signature processing on block header information included in the block. The block header information includes a first Merkel root determined based on transaction data in the block body information. Digest calculation on the block header information is performed to obtain first digest information. De-signature processing is performed on the digital signature to obtain second digest information. A second Merkel root is determined based on the transaction data acquired from the block proposal information when the first digest information and the second digest information are matched. An operation on the block is performed based on a comparison result of the first Merkel root and the second Merkel root.Type: ApplicationFiled: November 7, 2023Publication date: February 29, 2024Applicant: Tencent Technology (Shenzhen) Company LimitedInventors: Qucheng LIU, Zongyou WANG, Jinsong ZHANG, Gengliang ZHU, Yifang SHI, Hanqing LIU, Yingjie GUO, Zhiyong LIAO, Hu LAN

Patent number: 10733451Abstract: An n-lane automatic license plate recognition system (where n is an integer greater than one) and a method for dropping video frames in this system is disclosed. The method includes receiving, at an input of a first stage of a two-stage restrictor, a plurality of video frames. In the first stage of the two-stage restrictor, a subset of the plurality of video frames is dropped. An output of the first stage is coupled to an input of a second stage of the two-stage restrictor such that receiving and non-receiving of individual ones the plurality of video frames by the second stage is controlled by the first stage. In the second stage after the first stage, a further subset of the plurality of video frames is dropped to effect controlled frame input into a processor that performs at least one recognition analytic on remaining video frames of the plurality of video frames. The dropping of the further subset is based on at least one drop condition including a lane-specific drop condition.Type: GrantFiled: May 24, 2018Date of Patent: August 4, 2020Assignee: AVIGILON CORPORATIONInventors: Daniel James Booth, Thanh Tam Ho, Jinsong Zhu

Patent number: 8416416Abstract: The invention provides an SPR measuring method and a measuring system thereof. According to the measuring method, first, a linear-polarized coherent broadband pulsed light beam is incident onto a surface of a sample under detection of a SPR sensing device to cause reflection; next, a time-domain monotonous chirp is performed on the incident coherent broadband pulsed light and/or the SPR reflected light; finally, the time-domain monotonically chirped SPR reflected light beam is detected, and information of the SPR effect is obtained according to the detected signal. According to the invention, the spectrum detection method used in conventional slow wavelength interrogation is converted into the high-speed real-time detection of time-domain pulse shape signals. Thus, the procedure of the SPR reaction may be monitored closely, and dynamical curves with very high time resolution may be obtained, in that case, fast biochemical reaction procedures may be monitored.Type: GrantFiled: November 29, 2007Date of Patent: April 9, 2013Assignees: National Center for Nanoscience and Technology, Beihang UniversityInventors: Zheng Zheng, Yuhang Wan, Xin Zhao, Jinsong Zhu, Jiangfeng Fan
