Patent number: 11855681Abstract: System and method for processing an analog signal. For example, a demodulator for processing an analog signal includes one or more analog-to-digital converters configured to receive an analog signal and generate a digital signal based at least in part on the analog signal, and a correlator coupled to the one or more analog-to-digital converters and configured to generate a stream of correlation results including a first plurality of correlation results, a second plurality of correlation results, and a third plurality of correlation results. The first plurality of correlation results is different from the second plurality of correlation results by at least one correlation result, and the second plurality of correlation results is different from the third plurality of correlation results by at least another correlation result.Type: GrantFiled: November 9, 2020Date of Patent: December 26, 2023Assignee: Guangzhou On-Bright Electronics Co., Ltd.Inventors: Jiaqiang Huang, Jiapeng Zhang

Patent number: 11845896Abstract: A structural stabilizer for a fiber and proppant complex to enhance proppant migration and placement in a fractured well during propping and a preparation method thereof are provided. The structural stabilizer consists of: water, inorganic salt, kaolinite, nitrogen-doped modified graphene oxide, anionic surfactant, non-ionic alkyl polyglucoside, and polyacrylamide. The structural stabilizer improves bonding between a proppant and a fiber when slick water is used in stimulated reservoir volume (SRV) fracturing, prevents separation of the fiber and the proppant during migration, thereby reducing escape rate of the fiber from the fiber and proppant complex.Type: GrantFiled: July 13, 2023Date of Patent: December 19, 2023Assignees: Chengdu LEPS Technology Co., Ltd, Southwest Petroleum UniversityInventors: Jianchun Guo, Shan Ren, Hao Yang, Yingxian Ma, Kun Wang, Jiyu Wang, Cong Lu, Jiapeng Zhang, Zhihong Zhao, Shaobin Zhang, Qianli Lu, Qingsong Guo, Su Diao, Chi Chen, Xin Lei, Mingyuan Zhou, Chaojun Tang

Publication number: 20230216011Abstract: Provided are a bracket and a LED device. The bracket includes a lead frame and a molded structure connected to the lead frame. The lead frame includes a first lead portion, a second lead portion, and a barrier structure. The first lead portion includes a first base. The second lead portion includes a second base spaced from the first base. A gap between the first base and the second base forms a channel. The barrier structure is disposed on a side of at least one of the first base or the second base facing the channel. The barrier structure is disposed between two opposite ends of the first base and/or the second base and protrudes from the first base and/or the second base, and a length between two opposite ends of the channel is greater than a length of a middle part so that a “wide-narrow-wide” pattern is formed.Type: ApplicationFiled: December 29, 2022Publication date: July 6, 2023Applicant: FOSHAN NATIONSTAR OPTOELECTRONICS CO., LTD.Inventors: Libing PAN, Zhiguo XIE, Man ZHAO, Jiapeng ZHANG, Danwei LI, Pingxia LIANG, Fuhai LI

Publication number: 20230215999Abstract: Provided is an LED device. The LED device includes a bracket and a chip. The bracket includes a lead frame and a molded structure connected to the lead frame. The molded structure includes a chip placement body and a reflective structure. The chip placement body defines an avoidance groove. The reflective structure is a cylindrical structure with an inner through hole. The inner through hole communicates with the avoidance groove. The cylindrical structure is disposed around the periphery of the chip placement body. A first end of the cylindrical structure is formed with an opening communicating with the inner through hole. A second end of the cylindrical structure is connected to the chip placement body in the entire circumferential direction. A circumferential sidewall of the inner through hole forms a reflective surface used for reflecting light.Type: ApplicationFiled: December 28, 2022Publication date: July 6, 2023Applicant: FOSHAN NATIONSTAR OPTOELECTRONICS CO., LTD.Inventors: Libing PAN, Zhiguo XIE, Jiapeng ZHANG, Man ZHAO, Yinling ZHENG, Pingxia LIANG, Fuhai LI
