International Classification:

G06K 9/00

US Classification:

2504581

Abstract:

Systems for preparation of a mark and authentication of a mark vis-a-vis a counterfeit mark. Emission spectra comprising intensity versus wavelength distributions are collected from a series of taggants. One or more taggants is selected from the collected emission data such that the spectra of the selected taggants are distinguishable. The selection is also based on a consideration of the emitted radiation of a substrate and a dispersive medium. The authentication system uses multivariate statistical analysis to calculate at least one measurement statistic of a mark to be authenticated and at least one statistical limit based on a series of training marks prepared by the preparation system. Authenticity of the mark is determined based on a comparison of the measurement statistic and the statistical limit.

International Classification:

G01N 2100

US Classification:

Abstract:

A system for obtaining reliable data from a chemical sample for at least one variable environmental condition utilizing a photometer. The photometer obtains sample characteristic data at a plurality of discrete wavelengths. The reliability of the data is determined by obtaining a training set of data, and obtaining a number representing the variation between the mean center of the training set of data and the data representing the sample characteristic obtained by the photometer. Such number represents the basis of determining outliers of the data representative of the reliability of the data.

G01N 33/28

Abstract:

A process for on-line density measurement for a hydrocarbon fluid. The hydrocarbon fluid is caused to flow through first and second density sensors arranged in series. The first density sensor has a first temperature and the second density sensor has a second temperature, defining a temperature difference between the first temperature and the second temperature. A first density measurement and second density measurement are received from the first and second density sensors, respectively. A temperature conversion factor is determined. The first density measurement or the second density measurement is corrected using the determined temperature correction factor to provide a temperature-corrected density measurement.
