    摘要： In a wave soldering apparatus including a station for forming a standing wave of foamed flux, a preheater station, and a standing wave of hot molten solder station, a flux removing apparatus for reducing the thickness of flux on a coated printed circuit board includes an apertured pipe for gently blowing a plurality of streams of air against the foam coated board, the streams acting effectively as a continuous linear stream of air. The airstreams also blow the foamed flux into apertures in the printed circuit board.

    摘要： The present invention is directed to a method and apparatus that involves improved characterization of an object based on its surface roughness and other unique features without having to necessarily define a fixed and predetermined region of interest. In accordance with one aspect, the present invention provides a method for characterizing an object based on a pattern of the object's surface roughness. The method comprises the steps of obtaining a unique image of a feature on the surface of the object, converting the image obtained into certain electrical signals and processing the electrical signals so they are associated with the object and thereby provide a characterization of the object that is used to generate a unique identifying signature for the object.

    摘要： Systems and techniques for row guidance parameterization with Hough transform are described herein. An electronic representation of a field (ERF) can be received. The ERF can include a set of feature sets including one of a set of crop row features or a set of furrow features. A first parameter space can be produced by applying a slope-intercept Hough transform (SLIHT) to members of a feature set. Peaks in the first parameter space can be identified. A second parameter space can be produced by application of the SLIHT to the peaks. A vanishing point can be calculated based on a vanishing point peak in the second parameter space. A track-angle error can be calculated from the vanishing point.
