Amy J. Gates has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Microstructured screen with light absorbing material and method of manufacturing
    Patent number: 7184210
    Abstract: A film for a screen has a light transmitting substrate and a plurality of structures disposed on the substrate. An optical material at least partially fills cavities between the structures. A method of forming a film includes providing a light transmitting substrate having a plurality of structures disposed thereon and at least partially filling the cavities therebetween with an optical material.
    Type: Grant
    Filed: March 23, 2006
    Date of Patent: February 27, 2007
    Assignee: 3M Innovative Properties Company
    Inventors: Patrick A. Thomas, John C. Nelson, Scott M. Tapio, Michael L. Graetz, Amy J. Gates, Peter M. Olofson, Robert L. Brott, Robert S. Moshrefzadeh
  • Optical material adhesive, film including optical material and projection screen including film
    Patent number: 7142361
    Abstract: An optical material includes an adhesive formed from perfluoroalkylsulfonamidoethyl acrylate, aliphatic urethane acrylate oligomer and acrylate monomer. A film can include a first layer, a second layer disposed on the first layer and a polymerized composition disposed between the first and second layers and attaching the first layer to the second layer, the composition including perfluoroalkylsulfonamidoethyl acrylate, aliphatic urethane acrylate oligomer and acrylate monomer. A film can include a substrate and a plurality of structures disposed on the substrate, each of the structures formed by polymerizing a composition including perfluoroalkylsulfonamidoethyl acrylate, aliphatic urethane acrylate oligomer and acrylate monomer.

  • Composition for microstructured screens
    Patent number: 7050227
    Abstract: A composition having at least about 10 percent perfluoroalkylsulfonamideoethyl acrylate; at least about 5 percent aliphatic urethane acrylate oligomer; at least about 1 percent acrylate monomer; and less than about 84 percent other reactive and non-reactive components. The composition, with the addiction of a light absorbing pigment, is particularly useful as a light absorbing adhesive in an optical element such as a rear projection screen that incorporates totally internally reflecting structures to disperse the light passing through the screen.
