Filed:

Dec 28, 2004

Appl. No.:

11/024326

Inventors:

Brett Lucht - Wakefield RI, US
William B. Euler - Narragansett RI, US
Yu Wang - Worcester MA, US

Assignee:

The Board of Governors for Higher Education, State of Rhode Island and Providence Plantations - Providence RI

International Classification:

G01N 31/00
G01N 33/00

US Classification:

2524081

Abstract:

A thermal indicator material which comprises a plurality of polythiophenes having a second low temperature color and a high temperature color. The polythiophenes are structured and arranged to exhibit a color change from the second low temperature color to the high temperature color when the thermal indicator material is exposed to a temperature that meets or exceeds a pre-determined temperature and to exhibit a color change from the high temperature color to a first low temperature color when the thermal indicator material is exposed to a decline in temperature from a temperature that meets or exceeds the predetermined temperature to a temperature of within the range of between about 5 to 20 C. below the pre-determined temperature that occurs in a time period of greater than 2. 0 seconds.

G01N 21/76

US Classification:

2524081, 436172

Abstract:

The invention is directed to use of polythiophenes in a method to determine the genuineness of an article which method comprises providing an article treated with a composition comprised of a polythiophene, the polythiophene having a low temperature color and a weak fluorescence and the structure of the polythiophene being designed such that when the composition is placed in a heat-exchange relationship with the article, the low temperature color will change to a high temperature color and the weak fluorescence will change to a strong fluorescence when a pre-determined temperature is met or exceeded in the article, heating the article to a temperature that meets or exceeds the pre-determined temperature and detecting the color and the fluorescence change.

Inventors:

Yu Wang - Edison NJ, US

International Classification:

G06F 15/173
G06F 11/00

US Classification:

709224, 709223, 714 41

Abstract:

A data server computer ring including first and second data server computers, and any number of further data server computers. The data server computer “ring” can include any configuration in which the data server computers are connected together by communications links. The first and second data server computers are programmed by a computer program so that when one of the first and second data server computers is not operating, so that it is a non operating data server computer, the other of the first and second data server computers takes over one or more functions normally performed by the non operating data server computer.

Assignee:

International Classification:

G01N 21/93

US Classification:

73 103

Abstract:

A method is provided of calibrating a system that detects presence of a pollution component within exhaust gases proceeding along an exhaust passageway. A measurement cell of a probe is isolated by movement of either the entire probe or a shield within the probe from the exhaust gas to allow reference gas to be detected by a laser beam in the mid-infrared range in the measurement cell to calibrate the system. In another example, a laser source is placed on one side of an exhaust passageway and a detector is placed on the other side. A reference cell is provided that is used to receive reference gas and calibrate the system. In yet another example, the exhaust gas is extracted from the passageway and is measured in a reference cell. The reference cell is also filled with reference gas when it is desired to calibrate the system.
