Appl. No.:

11/732630

Inventors:

Charles C. Wang - Arcadia CA, US
Lan Xu - Cerritos CA, US

International Classification:

H04L 5/12
H04L 23/02

US Classification:

375261, 375265, 375241

Abstract:

Hierarchical modulation preferably uses a 16-ary quadrature amplitude modulation (QAM) modulator with a convolutional encoder that combine to effectively provide unequal protection to two different segments of streaming input data, with improved power efficiency with the same bandwidth efficiency, by encoding the first segment as coded data as LSBs as the second segment remains uncoded as uncoded MSBs, with the MSBs used for QAM constellation modest reliability interquadrant demodulation and detection, and with the LSBs used for low reliability intraquadrant detection, but with the LSBs subject to convolutional encoding and decoding rendering the LSBs with high reliability detection, such that, the two segments have unequal coding and modulation for providing unequal levels of reliability detection.

International Classification:

H01L 31/0216
B05D 5/12

US Classification:

136256, 427 74

Abstract:

The present invention provides a protective backing sheet for photovoltaic modules. The backing sheets of the current invention possess excellent weather resistance, heat resistance, color retention, adhesion between layers and encapsulant, and scratch resistance. The backing sheet can minimize the deterioration in the performance of the solar module due to moisture permeation. It also can achieve desirable photoelectric conversion efficiency over a long period of time. Additionally the described backing sheet, or alternately referred to backskin, can be made in an aesthetically pleasing form.

US Classification:

424618

Abstract:

A method of coating a substrate with the biocide particles dispersed into a coating permitting the antimicrobial particles to be positioned on the substrate such that they are in contact with the environment is provided. In the method, one or more biocides agents are dispersed into a coating. The coating with the biocide agent is applied to a substrate at a thickness such that at least some of the individual biocide particles extend beyond the surface of the coating.
