Abstract: A brushless system for washing a large flat object having a length greater than a width, the width defining a cross-section, said system including a frame defining a longitudinal path and including a first end; a second end; and a wash chamber positioned between said first and second ends.

Abstract: A method for determining a level of solar radiation at a point of interest (POI). Multiple sky images are captured by a distributed network of digital cameras. Sun location parameters are determined. A three-dimensional (3D) sky model is generated based on the sky images. Generating the 3D sky model includes generating 3D object data based on the sky images to model one or more objects in a region of sky, and generating position data to model a position of the one or more objects in the region of sky. A level of solar radiation at the POI is determined based on the position data and 3D object data of the 3D sky model and the sun location parameters.

Abstract: A pickup reel assembly that includes a hub and multiple bat assemblies where each bat assembly rotates through a functional area where it moves crop material into a harvester, and a non-functional area where it does not move crop material into the harvester. Each bat assembly rotates at a first speed through the functional area and at a second speed through the non-functional area, where the second speed is greater than the first speed. A nominal speed shaft can rotate at the first speed, and an increased speed shaft can rotate at the second speed. Cogs can couple the bat assembly to the increased speed shaft when it is in the non-functional area. The cogs can also couple the bat assembly to the nominal speed shaft when it is in the functional area.

Abstract: A method for detecting faulty operation of a multi-variable system is described. The method includes receiving operational data from a plurality of components of the multi-variable system and processing the operational data in accordance with a plurality of dynamic machine learning fault detection models to generate a plurality of fault detection results. Each fault detection model uses a plurality of variables to model one or more components of the multi-variable system and is adapted to detect normal or faulty operation of an associated component or set of components of the multi-variable system. The plurality of fault detection results are output.
