Cigar tobacco leaf harvesting maturity identification method and system based on integrated learning
Patent number: 12632960Abstract: A cigar tobacco leaf harvesting maturity identification method and system based on integrated learning are provided. The method comprises: acquiring an image of a cigar tobacco leaf to be detected, and preprocessing the image of the cigar tobacco leaf to be detected; carrying out vectorization dimensionality reduction on the preprocessed image of the cigar tobacco leaf to be detected, and extracting RGB and HSV eigenvalues to obtain a feature set; carrying out feature dimensionality reduction on data in the feature set by using a Wrapper algorithm to obtain an initial data set of the image of the cigar tobacco leaf to be detected; and inputting the initial data set into a trained random forest model, and outputting a maturity identification result of the image of the cigar tobacco leaf.Type: GrantFiled: June 12, 2023Date of Patent: May 19, 2026Assignee: Hubei Provincial Tobacco Research InstituteInventors: Chunlei Yang, Guangwei Sun, Jinpeng Yang, Jun Yu, Xiongfei Rao, Wencan Pei, Xiaowei Liu, Jing Liu, Jinguo Huang -
Patent number: 12532908Abstract: The invention discloses a high-yield integrated production method for cigar wrappers. This method builds a “four in one” production facility system that integrates seedling cultivation, transplanting, drying, and fermentation processes of cigar wrapper tobacco leaves. The system has a light intensity of 75-160 ?mol/(m2·s), a temperature of 25±5° C. and a relative air humidity of 75%±10%; when transplanting tobacco seedlings, using a nutrient solution, which is a high iron boron nutrient solution with an iron content of 0.3-0.7 mM calculated as Fe and a boron content of 9.5-13.0 mg/L calculated as boric acid. The invention achieves a cigar shell yield of over 65%, a 40% reduction in production facility investment, and a 20% reduction in labor force by accurately regulating the production environment and the supply of growth factors such as nutrients and light.Type: GrantFiled: March 29, 2025Date of Patent: January 27, 2026Assignee: Tobacco Research Institute of Hubei ProvinceInventors: Chunlei Yang, Jinpeng Yang, Jun Yu, Sicheng Liu, Xiongfei Rao, Kaixiao Fan, Chuanzong Li, Wenchang Huang, Gang Liu, Guangwei Sun, Jingguo Sun, Yulei Zhao, Peijun Lv, Youlun Fan

Publication number: 20250331894Abstract: A method for preparing a thermosensitive submucosal injection for endoscopic submucosal dissection (ESD), relating to the technical field of regenerative medicine. The specific method involves constructing a novel thermosensitive submucosal injection solution capable of sustained-release hemostatic drugs and growth factors using high-pH chitosan, polyvinylpyrrolidone, calcium ions, and disodium ?-glycerophosphate. This injection has very low viscosity, does not require special injection devices, is able to be injected using conventional endoscopic injection needles currently used in clinical practice, and exhibits high injection rate. Additionally, after being injected into the submucosal layer, this injection rapidly forms a high-strength hydrogel under body temperature, more stably supporting the raised state of the mucosal layer to facilitate ESD operations.Type: ApplicationFiled: July 9, 2025Publication date: October 30, 2025Inventors: Siyu SUN, Yang LIU, Guangwei SUN

Publication number: 20240344198Abstract: An assembly includes a backing plate and a diffuser plate configured to be disposed under the backing plate. The diffuser plate forms purge holes in a first region of the diffuser plate between a diffuser plate upper surface and a diffuser plate lower surface. The diffuser plate forms perforated area holes in a second region of the diffuser plate between the diffuser plate upper surface and the diffuser plate lower surface. Each of the perforated area holes has a first width at the diffuser plate upper surface and a second width at the diffuser plate lower surface. The second width is larger than the first width.Type: ApplicationFiled: April 9, 2024Publication date: October 17, 2024Inventors: Guangwei Sun, Jeffrey A. Kho, Lai Zhao
