Abstract: An exemplary apparatus determines the dimensions of a package while being moved by a transport through a scanning zone. Sensors with different respective fields of view are disposed about a scanning zone and generate corresponding frames of 3-D images where some of the points represent the transport and package. A computing apparatus translates the points in the images into a transport coordinate system with a common point of origin on the transport so that the package does not appear to be in motion from frame to frame. The computing apparatus merges the translated points in different frames into a combined point cloud image and deletes points representing the transport resulting in a final point cloud image of the package. The computing apparatus determines the dimensions of the package based on the location of points representing the package in the final point cloud image.

Abstract: A probe tower for an automatic test system includes an insulative retainer for holding an array of differential probe assemblies. Each differential probe assembly is an elongated structure having first and second ends and first and second coaxial portions. Each coaxial portion includes an outer conductor and a pair of annular insulators positioned therein for holding a center conductor. First and second contact pins extend from the center conductor at the first and second ends, respectively. First and second ground pins, which are electrically connected to the outer conductors of the first and second coaxial portions, extend from the first and second ends for conveying ground connections.
