US Patent:

6871966, Mar 29, 2005

Filed:

Dec 12, 2002

Appl. No.:

10/317812

Inventors:

Dennis I. Couzin - Evanston IL, US
Steven R. Chapman - Niles IL, US
Kejian Huang - Buffalo Grove IL, US

Assignee:

Avery Dennison Corporation - Pasadena CA

International Classification:

G02B005/124

US Classification:

359530, 359900, 264 19

Abstract:

A cube corner array with minute modifications of the dihedral angles of some of the cube corners is produced by introducing a stress or change via the opposite side of the substrate. The array having aberrated elements can be replicated for use in the manufacture of a tool, and the tool can be used in the manufacture of retroreflective products of broader divergence.

12/202739

Inventors:

Steven R. Chapman - Glenview IL, US
Feng Wu - Lake Zurich IL, US
Kejian (Kevin) Huang - Buffalo Grove IL, US

Assignee:

Avery Dennison Corporation - Pasadena CA

International Classification:

G02B 5/124

US Classification:

359530, 359529

Abstract:

A retroreflective sheeting () comprising a cube layer () having a front light-receiving surface () and a rear retroreflecting surface (), and a metallic layer () covering the rear retroreflecting surface (). The rear surface () comprises an array of retroreflective elements () and diffusing patches () within such array (without retroreflective elements ()). The metallic layer () covers the retroreflective elements () and the diffusing patches (), whereby diffusing patches () scatter incoming light increasing daytime brightness to a desired level.

Kejian (Kevin) Huang - Buffalo Grove IL, US
Feng Wu - Lake Zurich IL, US

International Classification:

B29D 11/00

US Classification:

264 25

Abstract:

A method of making an array () of aberrated optical elements (). The method comprises the steps of providing a substrate having a first surface with forming elements thereon, and controlled working a localized region on the first surface of the substrate. The controlled working is of a magnitude sufficient to aberrate one or more of the forming elements in an affected site surrounding the localized region.
