Patent number: 11839633Abstract: The composition is an herbal supplement comprised of hydrolyzed whole soybean, Bacillus amyloliquefaciens, lactic acid bacteria, the mushroom, Auricularia polytricha, and turmeric. The soybean feeds the bacterial components of the composition to increase their biomass. The Bacillus amyloliquefaciens produces protease and amylase enzymes which hydrolyze the proteins and carbohydrates in the soybean into smaller peptides and oligosaccharides. These smaller nutrients are more easily absorbed by the gastrointestinal tract. The lactic acid bacteria are probiotics which limit the growth of Bacillus amyloliquefaciens in the composition thus balancing the gastrointestinal microbiome. The mushroom, Auricularia polytricha enhances blood flow, removes toxins from the bowel, stabilizes the digestive system and enhances digestion. Turmeric is an antioxidant, anti-ulcer, anti-bacteria (including the suppression of Helicobacter pylori bacteria), anti-inflammatory.Type: GrantFiled: March 17, 2020Date of Patent: December 12, 2023Assignee: SVK Herbal CorporationInventors: Cuong Van-Dinh, Nam Van Tran, Phuong Chien Le, Hai Hoang Nguyen

Publication number: 20180094786Abstract: The invention introduces converging lenses connecting with optical fibers and a device for receiving sunlight that uses these lenses to converge sunlight from every angle of the sun during the day and the collected light beam at the output is quite parallel. To converge light from every angle of the sun, without using any motion part, small lenses are arranged to build a convex surface. Sunlight collected by these lenses become a parallel light beam and are guided by optical fibers. These optical fibers are arranged tightly to build a bundle of optical fibers in order to make it easier to further transmit and to use at the output of the device.Type: ApplicationFiled: October 12, 2017Publication date: April 5, 2018Applicant: University of Science, Vietnam National University - HanoiInventors: Thuat Tran Nguyen, Hieu Chi Hoang, Quan Duc Ho, Quan Quang Nguyen, Hai Hoang Nguyen
