The invention relates to a method for the manufacture of a prophylactic article, especially of a glove, from a (carboxylated) diene rubber, according to which a layer of a (carboxylated) diene latex is applied on a former and the (carboxylated) diene latex is cross-linked with a cross-linking agent, which is immobilized on inorganic and/or organic particles with formation of modified particles, and the modified particles are added to the (carboxylated) diene latex.

A method including generating integrated computational element (ICE) models and determining a sensor response as the projection of a convolved spectrum associated with a sample library with a plurality of transmission profiles determined from the ICE models. The method includes determining a regression vector based on a multilinear regression that targets a sample characteristic with the sensor response and the sample library and determine a plurality of regression coefficients in a linear combination of ICE transmission vectors that results in the regression vector. The method further includes determining a difference between the regression vector and an optimal regression vector. The method may also include modifying the ICE models when the difference is greater than a tolerance, and fabricating ICEs based on the ICE models when the difference is within the tolerance. A device and a system for optical analysis including multiple ICEs fabricated as above, are also provided.

A seed sampling system is provided comprising an automated seed loading assembly operable to singulate seeds from a plurality of seeds or enable loading of individually stored seeds and an automated seed sampling assembly comprising at least one sampling module operable to remove tissue samples from one of the singulated seeds.

Provided is a method for detecting objects to be sorted with an optical sorter that can detect lateral portions of objects to be sorted with a flat shape.

A chute is provided with a plurality of parallel longitudinal grooves formed in the longitudinal direction by a plurality of elongated protruding walls, and objects to be sorted with a flat shape are allowed to flow downward on the surface of the chute such that substantially flat faces of the objects to be sorted touch the elongated protruding walls in the longitudinal grooves, and lateral portions of the objects to be sorted face the front-rear direction of the chute so that the optical detection unit detects the lateral portions of the objects to be sorted at the detection position. Preferably, the objects to be sorted with the flat shape are rice grains, and the optical detection unit detects bran remaining on back strings of the rice grains at the detection position.

A radio frequency (RF) grain mass and constituent measurement system utilized onboard a combine harvester includes an RF sensor subsystem for capturing RF sensor readings of a harvested grain within an area of the combine harvester. A memory stores an RF characteristic database, which contains RF characteristic testing data collected for tested grain samples over one or more tested frequency ranges. A controller, operably coupled to the RF sensor subsystem and to the memory, is configured to: (i) receive the RF sensor readings from the RF sensor subsystem; (ii) determine grain mass and a first constituent content of the currently-harvested grain based, at least in part, on an analytical comparison between the RF sensor readings and the RF characteristic testing data; and (iii) perform at least one action in response to determining the grain mass and the first constituent content of the harvested grain.
