US Patent:

8177374, May 15, 2012

Filed:

Jun 7, 2006

Appl. No.:

11/915390

Inventors:

Feng Wu - Lake Zurich IL, US

Assignee:

Avery Dennison Corporation - Pasadena CA

International Classification:

G02B 5/124

US Classification:

359530

Abstract:

A retroreflective sheet structure () comprising a transparent layer () having a front light-receiving surface () and a rear retroreflecting surface (). Light incident on the front surface () will pass through the layer (), impinge on the rear retroreflective surface () and reflect back out through the front surface () in a predetermined direction. An identifying indicia () is chosen and then formed on the retroreflecting surface (). This indicia () can be used for identification purposes, even years after an end product incorporating the reflective sheet structure () has been out in the field.

International Classification:

G02B 5/124

US Classification:

359530, 359529, 359900, 4271631

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.

Appl. No.:

12/473508

Inventors:

Feng Wu - Lake Zurich IL, US

Assignee:

Avery Dennison Corporation - Pasadena CA

International Classification:

G06K 7/10

US Classification:

359350

Abstract:

An infrared light transmission film includes a polymer matrix and at least one red colorant, blue colorant, and yellow colorant that are uniformly dispersed in the polymer matrix at amounts effective to allow transmission through the film of at least about 85% of light with wavelengths over about 800 nm while blocking transmission of at least about 90% of light with wavelengths less than about 750 nm.

International Classification:

G06F013/14

US Classification:

710/305000

Abstract:

As communications busses become more generic, the handshaking that occurs to provide communications become more complicated. The constant checking of signal lines for a stable and debounced signal can consume a considerable amount of overhead and greatly increase the complexity of the design of the hardware. An independent debouncing circuit and can be used to detect the presence of a stable and debounced signal and notify an interface engine A state machine executing in the interface engine uses the stable and debounced signals to control operation of a peripheral connected to the bus by monitoring signals passed on the bus.

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.
