METHOD AND APPARATUS FOR DETECTING PANEL CONDITIONS

摘要

A method and apparatus for detecting a predetermined condition of a panel by transmitting a cyclically-repeating energy wave through the material (41) of the panel from a first location (43a) to a second location (43b); measuring the transit time of the cyclically-repeating energy wave form the fist location to the second location; and utilizing the measured transit time to detect the predetermined condition including the force on, the temperature of, a deformation in, the fatigue condition of, or a fracture in, structural panel, the presence of a force applied to, water on, or breakage in of the panel.
