US Classification:

422 681, 422 8205, 422 62

Abstract:

The disclosure is directed to a test media reader module including a housing, a membrane, and an optical imager. The housing is configured to receive a test media adapter and has a barrier wall configured to separate the test media adapter from an interior of the housing. The barrier wall includes a window having an interior side and an exterior side. The membrane is transparent to a wavelength useful for imaging test media in the test media adapter. The membrane has a reactive region and overlies at least a portion of the exterior side of the window. The optical imager is located interior to the housing and is configured to image the test media located on the exterior side of the window along an optical path extending through the window and the membrane.

US Classification:

438 49, 438503, 438508

Abstract:

An array of sensor devices, each sensor including a set of semiconducting nanotraces having a width less than about 100 nm is provided. Method for fabricating the arrays is disclosed, providing a top-down approach for large arrays with multiple copies of the detection device in a single processing step. Nanodimensional sensing elements with precise dimensions and spacing to avoid the influence of electrodes are provided. The arrays may be used for multiplex detection of chemical and biomolecular species. The regular arrays may be combined with parallel synthesis of anchor probe libraries to provide a multiplex diagnostic device. Applications for gas phase sensing, chemical sensing and solution phase biomolecular sensing are disclosed.

International Classification:

G06N 3/00

US Classification:

703 11

Abstract:

Methods and tool are provided for managing rangeland in a consistent, repeatable and quantitative manner. A geospatial model of the land is created and used to select forage analysis targets and forage analysis routes within the land. Then, forage observation locations are determined from the forage analysis targets. Forage and area limiting attributes are then determined and applied to each forage observation location, and a representative extent of land is associated with each forage observation location. An amount of forage at each forage observation location is measured, and forage inventory is calculated based on the measured forage and relative spatial extent of land associated with each forage observation location. Land use policy may then be established, for grazing, hunting, recreation, and other uses.

US Classification:

2502081, 427162, 156 67

Abstract:

Spectroscopic filter arrays and methods for making spectroscopic filter arrays are provided. The arrays are formed using a dispersion of filter particles having selected moieties attached to the surface of the particles and a microarray having complementary moieties formed in an array on a substrate, such that each filter particle is attached to a selected region of the microarray. The moiety on the substrate may be RNA or DNA or other molecule. The substrate may be a surface of a photodetector array, a transparent plate that may be placed in registration with the photodetector or a stamp used to transfer the filter array to a photodetector array.

International Classification:

G01N 15/06

Abstract:

An apparatus comprises a housing defining a chamber that has a liquid disposed therein, and a sensor submerged in the liquid. The sensor comprises a porous conductive film on a substrate, and the film comprises chemiresistive semiconducting metal oxide structures. The sensor also comprises an electrode pair operably connected to the porous conductive film for generating electric current in the film and for detecting a change in an electrical property of the film. The apparatus can be used to detect, identify, and quantify ions and molecules in a liquid sample. Molecules and ions, in a liquid sample, that interact with the porous conductive film can cause a change in an electrical property of the film. The change in electrical property of the film can be correlated with the presence and amount of the molecules or ions.
