Abstract: The embodiments of the present invention provide novel techniques for visualizing parameter values, such as parameter values measured in an industrial measurement process. In particular, the disclosed embodiments provide visualization techniques for re-scaling a representation of a target parameter range with respect to an overall parameter range for a parameter value. Re-scaling the representation of the target parameter range effectively provides continuous dynamic zooming for the measured parameter value. This allows for better visualization as well as providing continuous feedback to an operator of the industrial measurement process regarding the current measured parameter value, thereby facilitating faster and more accurate operation of the industrial measurement process.

Abstract: A method and apparatus for characterizing a central circular aperture of a workpiece, for example a flexible information storage disk. The apparatus utilizes a noncontact sensor system having a rotary stage upon which the workpiece is placed. A reference edge extending approximately to the axis of rotation of the stage serves as a reference point from which a laser beam measures a plurality of radial distances extending from the reference edge to a plurality of points about the disk's central aperture. A computer utilizes these distances along with a known deviation of the reference edge from the center of rotation of the stage to construct a shape comprising a plurality of inscribed triangles. The center of the shape is found by mathematically determining its center of gravity. The center of gravity is then used to locate a reference coordinate system and precise reference circles are drawn around the center of gravity.
