US Patent:

20120142112, Jun 7, 2012

Filed:

Dec 7, 2010

Appl. No.:

12/961675

Inventors:

Vincent P. Schnee - Alexandria VA, US

Assignee:

United States of America, as represented by the Secretary of the Army - Fort Belvoir VA

International Classification:

G01N 33/00
G01N 23/00
G01N 21/76

US Classification:

436 34, 422 52, 436 57

Abstract:

A senor uses a transduction mechanism of attenuating electroluminescence. Luminescence from a light emitting diode is attenuated as a consequence of direct interaction of an analyte and a electroluminescent material, An electroluminescent diode sensor (EDS) is fabricated in a way that allows the electroluminescent material in the diode to be exposed to gaseous, liquid or solid sample(s) which may affect the luminescence intensity of the diode,

International Classification:

G02B 1/118
G02B 1/00
B29D 11/00

Abstract:

A method for manufacturing an anti-reflective coating on a surface of an optical component includes the steps of placing a moth eye structure material in apertures of a stamp; placing the stamp on the surface of the optical component such that the moth eye material is in contact with the surface of the optical component; and removing the stamp after the moth eye structure material adheres to the surface of the optical component to create an anti-reflective coating on the surface of the optical component.

Inventors:

- Fort Belvoir VA, US
Vincent P. Schnee - Alexandria VA, US

G01N 21/75

Abstract:

The discrimination ability of a chemical sensing cross-reactive arrays is enhanced by constructing sensing elements in two dimensions, first in the x-y plane of the substrate, second in the z dimension so that the sensors are vertically stacked on top of one another. Stacking sensing elements on top of one another adds to the discrimination ability by enabling the characteristic measurement of how fast target chemicals are passing through the stack of sensors. The new invention also allows the ability to discriminate components in a sample mixture by separating them using their innate difference in diffusional rates. Multi-sensor response patterns at each z level of sensors and time delay information from the sample passing from one level to the next are used to generate the response vector. The response vector is used to identify individual component samples and components in a mixture sample.
