Abstract:

A gage assembly to measure the diameter of a piece of tubing. The gage assembly is especially configured to take measurements during the extrusion manufacture of the tubing when an eccentricity in the outer diameter of the tubing is present. The gage assembly includes a pair of contact wheels mounted such that the space between them defines a path with a diamond-shaped cross section for the tubing to pass through. Each contact wheel includes cutouts that define a pair of planar contact surfaces that are angularly disposed relative to one another. As the tubing leaves the extruder, it axially passes through the diamond-shaped path, coming in contact with the planar surfaces of the contact wheels. The contact wheels are slidably and rotatably mounted such that translational movement imposed on the planar surfaces of the wheels due to eccentricities on the tubing outer surface are resolved into movement along a first translational direction, which is correlated to the size of the undulation in the tubing, then registered as output on an indicator. The angular positioning of the planar contact surfaces to one another permits the simultaneous measurement in two dimensions on the outer surface of the tubing, while the slidable mounting of the contact wheels ensures continued contact between both planar surfaces of each wheel and the tubing outer surface.

Abstract:

Described herein are various technologies pertaining to detecting a vehicle in an image and determining a class of vehicle to which the vehicle belongs. In a general embodiment, the image is output by a radar-based imaging system, such as a synthetic aperture radar (SAR) imaging system. The image is processed to generate a signature for the vehicle, the signature being a one-dimensional array. The class of the vehicle is determined based upon a comparison of the signature for the vehicle with a template signature for the class.
