view source
US Patent:

20110053271, Mar 3, 2011
Filed:

Aug 25, 2009
Appl. No.:

12/547144
Inventors:

Odessa N. Petzold - Elmira NY, US
Vasudha Ravichandran - Painted Post NY, US
Wageesha Senaratne - Horseheads NY, US
International Classification:

C12N 5/06
B05D 3/06
US Classification:

435404, 427533, 427535
Abstract:

A method for grafting a polysaccharide to a surface of a cell culture article includes (a) contacting the surface of the article with the polysaccharide in a dry form; and (b) exposing the surface of the article and contacted dry polysaccharide to ionizing radiation to graft the polysaccharide to the surface of the article. In addition to grafting the polysaccharide to the surface, the ionizing radiation may serve to sterilize the article.

International Classification:

F21V 8/00
G02B 5/02
C03C 17/32
C03C 15/00
Abstract:

A substrate with a textured surface is disclosed. The substrate may be, for example, a light emitter comprising a light guide, for example a backlight element for use in a display device, wherein a surface of the light guide, for example a glass substrate, is configured to have a textured surface with a predetermined RMS roughness and a predetermined correlation length of the texture. A plurality of light scatter suppressing features can be provided on the textured surface. Textured surfaces disclosed herein may be effective to reduce electrostatic charging of the substrate surface. Methods of producing the textured surface are also disclosed.

US Patent:

20180128957, May 10, 2018
Filed:

May 12, 2016
Appl. No.:

15/574260
Inventors:

- CORNING NY, US
Jacques Gollier - Redmond VA, US
Vasudha Ravichandran - Painted Post NY, US
Christine Coulter Wolcott - Horseheads NY, US
International Classification:

F21V 8/00
C03C 15/00
C03C 23/00
C03C 17/00
Abstract:

Disclosed herein are glass articles, such as light guide plates, comprising a first surface () and an opposing second surface (), wherein the first surface comprises an array of light extraction features () having a diameter of at least about 10 microns and a height ranging from about 1 micron to about 10 microns. Display devices comprising such glass articles are also disclosed herein as well as methods for producing such glass articles. The method involves depositing ink on a first surface of a glass substrate to form an array of coated and uncoated surfaces and etching the uncoated surfaces.

US Patent:

20170269466, Sep 21, 2017
Filed:

Jul 28, 2015
Appl. No.:

15/329803
Inventors:

- Corning NY, US
Jacques Gollier - Redmond WA, US
Joan Deanna Gregorski - Painted Post NY, US
Vasudha Ravichandran - Painted Post NY, US
David Lee Weidman - Corning NY, US
International Classification:

G03B 21/62
B32B 17/06
Abstract:

High contrast, glass-based, writeable/erasable front projection screens are provided. The screens include a transparent glass sheet which has a front surface and a back surface separated by a distance d. The back surface is in optical contact with a diffusing element. During use of the projection screen, the glass sheet transmits image light from a projector to the diffusing element and the diffusing element reflects a portion of that light back through the glass sheet to a user. The screens have a user-facing surface that is a writable/erasable surface. In embodiments, the distance d is less than or equal to 0.2 millimeters, the whiteness W of the projection screen is less than or equal to 0.5, and/or the contrast C of the projection screen is at least 75%.
