8298755, Oct 30, 2012

Filed:

Jul 28, 2008

Appl. No.:

12/181055

Inventors:

Allan S. Myerson - Chicago IL, US
In Sung Lee - Chicago IL, US

Assignee:

Illinois Institute of Technology - Chicago IL

International Classification:

G03F 7/20

US Classification:

430324

Abstract:

Methods for producing small crystals on islands formed on specialized substrates by, inter alia, subjecting the substrate to a hydrophilic SAMs solution for self-assembling hydrophilic SAMs on certain portions of the substrate surface and subjecting the substrate to a hydrophobic SAMs solution for self-assembling hydrophobic SAMs on certain other portions of the substrate surface.

Appl. No.:

12/181084

Inventors:

Allan S. Myerson - Chicago IL, US
In Sung Lee - Chicago IL, US

International Classification:

B32B 17/06

US Classification:

428426

Abstract:

Substrates for growing small crystals, the substrates having a first layer consisting of glass, polymer, and/or metal; a second layer having hydrophilic SAMs and hydrophobic SAMs, wherein the hydrophilic SAMs are located only on discrete islands on the first layer and the hydrophobic SAMs are located only on areas of the first layer free of hydrophilic SAMs.

Abstract:

An apparatus and a method of compressing and expanding a video signal. The apparatus includes a variable length coder controller and a quantizer. The coder controller compares a bit amount generated in the use of an optimum symbol with that in the use of an existing symbol upon detection of a scene change and outputs a new symbol upon the presence of a gain in accordance with the compared result. A frame delay delays input image data in a unit frame, a subtracter for subtracting an output signal of the frame delay from the input image data, and a scene change detector for detecting a scene change of the input image data. A motion detector detects a motion in the input image data, a main codebook for forming variable sub-codebooks for a still picture, a codebook controller for selecting a specified portion of the main codebook and variable sub-codebooks, and a vector formation unit for forming the input image data into a vector. A distortion measurement unit obtains a codeword with a minimum distortion using the variable sub-codebooks if the input image data is the still picture and using the main codebook if the input image data is a motion picture, and a code assignment unit for assigning a proper code to an output signal from the distortion measurement unit.
