International Classification:

G01J 3/40
G01N 21/85
G01N 33/48

US Classification:

356303, 356300, 356307, 356417, 356318, 356 39

Abstract:

Multivariate optical analysis systems employ multivariate optical elements and utilize multivariate optical computing methods to determine information about a product carried by light reflected from or transmitted through the product. One method of processing and monitoring the product includes introducing the product at an inspection point; illuminating the product with a spectral-specific light though an optic lens; directing the light that has passed through at least a section of the product through at least one multivariate optical element to produce a first signal, the directed light carrying information about the product; detecting the first signal at a first detector; deflecting a portion of the directed light to produce a second signal in a direction of a second detector, the second detector configured to detect the second signal; and determining at least one property of the product at a rate of about one section of the product per second to about five sections of the product per second based upon the detector outputs.

International Classification:

A63F 1/00

US Classification:

273298

Abstract:

Disclosed is a collector-targeted, memorabilia-bearing trading card set. Each comprises a plurality of cards originating from and assembleable into a set. Each card is formed from at least two layers of material, a first layer being at least a portion of memorabilia having a visual attribute exposed on one side of the card and a second layer that comprises a substrate providing an opposite side surface of the card. The opposite side surface has indicia conveying information related to the memorabilia of the first layer and associating it with the set from which it originated. The memorabilia attribute is positioned to have a portion of the attribute divided between at least two of the cards and extending across adjoining, cut edge portions of at least two cards of the set.

G06Q 10/00

US Classification:

705 7, 705 711, 705 737

Abstract:

Methods of assessing feasibility of a project include receiving a datum from a customer; designing an application specific system based on the datum; analyzing the datum; evaluating a set of input parameters to determine an applicability of the application specific system to a customer process; and providing feedback for the customer process with the application specific system.

International Classification:

G01N 21/17

US Classification:

2502082, 250206

Abstract:

Optical computing devices containing one or more integrated computational elements may be used to produce two or more detector output signals that are computationally combinable to determine a characteristic of a sample. The devices may comprise a first integrated computational element and a second integrated computational element, each integrated computational element having an optical function associated therewith, and the optical function of the second integrated computational element being at least partially offset in wavelength space relative to that of the first integrated computational element; an optional electromagnetic radiation source; at least one detector configured to receive electromagnetic radiation that has optically interacted with each integrated computational element and produce a first signal and a second signal associated therewith; and a signal processing unit operable for computationally combining the first signal and the second signal to determine a characteristic of a sample.

International Classification:

G01N 21/17

US Classification:

2502082, 250206

Abstract:

Optical computing devices are disclosed. One exemplary optical computing device includes an electromagnetic radiation source configured to optically interact with a sample and at least two integrated computational elements. The at least two integrated computational elements are configured to produce optically interacted light and further configured to be associated with a characteristic of the sample. The optical computing device further includes a first detector arranged to receive the optically interacted light from the at least two integrated computational elements and thereby generate a first signal corresponding to the characteristic of the sample.
