  • Patent number: 11839633
    Abstract: 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.

  • Publication number: 20230104072
    Abstract: Systems and methods for automating clothing transactions. The methods comprise: obtaining user input data and/or sensor data specifying characteristics of a body for an individual; transforming the user input data and/or sensor data into a 3D graphical representation of the body; analyzing the 3D graphical representation to derive 3D body measurements for the individual; identifying clothing items based on results from comparing the 3D body measurements to reference measurements associated with clothing items having different styles, sizes and brand associations; analyzing how a fabric elasticity and a garment construction could impact a fit of each identified clothing item relative to each body part of the individual based on the 3D graphical representation of the body; and filtering the clothing items based on results of the analyzing and fit preferences of the individual to generate recommended clothing items for the individual.

  • Publication number: 20180094786
    Abstract: 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.
