Patent number: 11943373Abstract: An identity certificate may be issued to a blockchain node. The issuance may include issuing a first identity certificate to a first terminal and receiving a second identity certificate issuance request that is from the first terminal. A second identity certificate may be issued to the first terminal, and a third identity certificate issuance request is received from the second terminal. A third identity certificate is issued to the second terminal, so that the second terminal forwards the third identity certificate to the third terminal.Type: GrantFiled: June 2, 2021Date of Patent: March 26, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Mao Cai Li, Zong You Wang, Kai Ban Zhou, Chang Qing Yang, Hu Lan, Li Kong, Jin Song Zhang, Yi Fang Shi, Geng Liang Zhu, Qu Cheng Liu, Qiu Ping Chen

Patent number: 8410765Abstract: A pulse modulation method for adjusting pulse signals according to a working voltage of a load, the method includes the following steps. The working voltage of the load is detected by a feedback terminal of a PWM controller. Whether the load is a light load or a heavy load is determined, if the load is a light load, a pulse skipping mode is entered; the voltage output to the load is detected by the feedback terminal. Whether the voltage output to the load is normal is determined, if the voltage output to the load is low, the pulse skipping mode is stayed for a number of clock cycles; the voltage output to the load is detected to determine whether the voltage is normal. If the voltage output to the load is still low, the pulse skipping mode is jumped out and a normal working mode is entered.Type: GrantFiled: November 30, 2010Date of Patent: April 2, 2013Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Hsiang-Jui Hung, Kun-Lung Wu, Yi-Ping Li, Yong-Xian Zhao, Shi-Tao Chen
