  • Uneven surface deflection and amplitude measurement tool
    Patent number: 9746305
    Abstract: A first aspect of the invention provides an apparatus to indicate an amplitude of an uneven measurement surface. The apparatus may include a frame slidingly supporting a set of pins, each pin including a high point stop and a low point stop; a low point isolator member moveable relative to the frame, the low point isolator member indicating a lowest point of the uneven measurement surface by a respective low point stop of a first; a high point isolator member moveable relative to the frame, the high point isolator member indicating a highest point of the uneven measurement surface by a respective high point stop of a second pin; a low point displacement sensor for identifying a low point displacement; a high point displacement sensor for identifying a high point displacement; and a calculator for calculating a difference between the low point displacement and the high point displacement.
