Patent number: 11967112Abstract: Described is a method for detecting a calibration requirement for image sensors in a vehicle. The method includes detecting a ground pattern in a generated image associated with a surrounding of a vehicle. The method includes extracting at least one key point associated with the detected ground pattern, from the generated image. The method includes determining a relative motion parameter associated with the extracted at least one key point based on tracking of the extracted at least one key point over a period of time. The method further includes detecting the calibration requirement for the image sensor based on the determined relative motion parameter and generating an output signal based on the detected calibration requirement.Type: GrantFiled: September 7, 2022Date of Patent: April 23, 2024Assignee: AitronX Inc.Inventors: Xinlu Tang, Chi Yan, Jiangwei Li, Jie Lin

Publication number: 20240108743Abstract: A linker peptide for constructing a fusion protein. The linker peptide comprises a flexible peptide and a rigid peptide. The flexible peptide consists of one or more flexible units. The rigid peptide consists of one or more rigid units. The flexible unit comprises two or more amino acid residues selected from Gly, Ser, Ala, and Thr. The rigid unit comprises a human chorionic gonadotropin ?-subunit carboxy-terminal peptide (CTP) bearing a plurality of glycosylation sites. The linker peptide can more effectively eliminate mutual steric hindrance of two fusion molecules, decreasing a reduction/loss of polymerization or activity resulting from improper folding of an active protein or a conformational change. On the other hand, the negatively charged, highly sialylated CTP can resist renal clearance, further prolonging a half-life of a fused molecule and enhancing bioavailability of a fused protein.Type: ApplicationFiled: October 24, 2023Publication date: April 4, 2024Inventors: Qiang LI, Yuanli LI, Si CHEN, Zhu WANG, Zhao DONG, Zirui LI, Xinlu MA, Lu YANG, Yongjuan GAO, Yuncheng ZHENG, Naichao SUN
