Patent number: 11965833Abstract: A detection device includes a frame, a transport mechanism, detection mechanisms, and a grasping mechanism. The transport mechanism includes a feeding line, a first flow line, and a second flow line arranged in parallel on the frame. The detection mechanisms are arranged on the frame and located on two sides of the transport mechanism. The grasping mechanism is arranged on the frame and used to transport workpieces on the feeding line to the detection mechanisms, transport qualified workpieces to the first flow line, and transport unqualified workpieces to the second flow line.Type: GrantFiled: November 26, 2020Date of Patent: April 23, 2024Assignees: HONGFUJIN PRECISION ELECTRONICS (ZHENGZHOU) CO., LTD., HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Jing-Zhi Hou, Lin-Hui Cheng, Yan-Chao Ma, Jin-Cai Zhou, Zi-Long Ma, Neng-Neng Zhang, Yi Chen, Chen-Xi Tang, Meng Lu, Peng Zhou, Ling-Hui Zhang, Lu-Hui Fan, Shi-Gang Xu, Cheng-Yi Chao, Liang-Yi Lu

Patent number: 11128450Abstract: A signature generation method performed by an electronic apparatus is provided. A message abstract is generated according to a to-be-signed message and eigenvalues of a plurality of signature parties, an eigenvalue of a signature party being based on a random number of the signature party. Public keys and sub signatures of the plurality of signature parties are obtained, and a sub signature of the signature party is based on the random number of the signature party, the message abstract, and private keys of the plurality of signature parties. An aggregation public key is generated according to the public keys of the plurality of signature parties, and a length of the aggregation public key is less than a length of the plurality of public keys after splicing. An aggregation signature is generated according to a sum value of the plurality of sub signatures and the message abstract.Type: GrantFiled: November 7, 2019Date of Patent: September 21, 2021Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LTDInventors: Jian Jun Zhang, Li Lei Wu, Hai Tao Tu, Mao Cai Li, Li Kong, Zi Chao Tang, Wen Wei Zou, Jun Zang
