  • Publication number: 20240150937
    Abstract: Provided herein are protective masks made with polymer-based materials and methods of forming the materials. Methods of forming the interlaced polymer-based materials comprise applying adhesive to a substrate, electrospinning a first polymer solution onto the substrate from a first group of spinning electrodes, electrospinning a second polymer solution onto the substrate from a second group of spinning electrodes, and applying hot air to dry the polymer-based materials electrospun from the first polymer solution and the second polymer solution to form the interlaced polymer-based materials.

  • Patent number: 6813440
    Abstract: A compact moiré effect body scanner provides 3-D images of a human body for use in making up suitable garments. The scanner includes an elongate projection module with a photographic grid that illuminates the body. An elongate imaging module having a second photographic grid lies alongside the projection module and a digital camera is used to capture images of the body. The scanner is typically about 400 mm long, 400 mm high, and 150 mm wide and can be used in normal room light conditions.

  • Patent number: 6521396
    Abstract: High density and contrast range photographic grids for a moiré body scanner are made by a method including forming an image on a high density technical grade film, providing a recommended commercial developer chemical for said high density technical grade film, preparing a modified developer liquid from said recommended commercial developer chemical by increasing the pH and the contrast of developer reducing agent, and developing a black and white image using said modified developer liquid. The modified developer liquid also finds other applications.
