US Patent:

20130188182, Jul 25, 2013

Filed:

Jan 17, 2013

Appl. No.:

13/743457

Inventors:

Brian Garrett - Cary NC, US
Todd Blonshine - Cary NC, US
W. Stanley Ayers - Cary NC, US

International Classification:

G01J 3/44

US Classification:

356301

Abstract:

A Raman spectrometer optically separates an optical signal scattered by a sample from an incident excitation light beam into an unshifted return component at a first wavelength and one or more Raman scattered components at shifted wavelengths characteristic of the sample. The unshifted return component—but not the Raman scattered components—is attenuated prior to impinging on an optical detector. The unshifted return then serves as the basis for real-time calibration to account for fluctuations in optical intensity, wavelength shift, and/or spectral peak width, based on a comparison of the unshifted return peak to a reference standard for stable reflectance.

International Classification:

G06F 19/00

US Classification:

702180, 702189

Abstract:

A rule-based verification testing methodology automates the process and allows for field deployment of verification testing instrumentation. A rule-based chemical monitoring methodology automates the verification of a chemical being monitored, as well as the instrument and a sample path, increasing the confidence in the verification process. In both methods, at least Raman spectra of a sample are captured, and compared to a model that is based on reference data. Predetermined, flexible, parameterized rules control the comparison. Additional physical properties, such as color and size, may also be compared (also controlled by predetermined rules).

Abstract:

A method of expert peer identification includes receiving, from a user, a request for an expert peer for an asset type, and obtaining asset interaction data relevant to the request including a list of assets, and, for each asset on the list, values for each of a set of pre-defined interaction categories for each worker that has interacted with the asset. The method further includes, for each asset on the list, respectively multiplying the interaction category values by a corresponding set of category weights to obtain a set of weighted interaction values, and, for each worker, processing the sum of their weighted interaction values to obtain an overall centrality measure. The method also includes selecting one of the workers as the expert peer based, at least in part, on their overall centrality measure, and identifying the expert peer to the user.
