Title: August F. Scarpelli: Innovator in Tomography and Ultrasonic Measurement

Introduction

August F. Scarpelli is a notable inventor based in Warren, MI (US), recognized for his contributions to the fields of tomography and ultrasonic measurement. He holds a total of 3 patents, showcasing his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is the "Sinography method and apparatus." This tomography apparatus is designed to irradiate a body cross-section and acquire a relatively small amount of data, which is then mapped into a two-dimensional array or sinogram. Image enhancement techniques are applied to the sinogram to reveal visible lines representing flaws. An array processor operates on the sinogram to perform edge enhancement and averaging convolutions, a fast Fourier transform, low pass filtering in the frequency domain, and an inverse fast Fourier transform to generate the enhanced sinogram.

Another significant patent is the "Ultrasonic multilayer paint thickness measurement." This invention utilizes ultrasonic thickness measurement of layers of paint on a substrate, producing pulse echoes indicative of each layer interface. Several ultrasonic waveforms are averaged in a digital oscilloscope, and the resultant waveform is analyzed by a computer programmed to recognize waveforms resembling pulse echoes. The computer compares these waveforms to stored reference waveform characteristics and selects the waveform with the best fit to the reference. Each selected pulse echo is graded based on amplitude, peak separation, peak symmetry, and spacing from a previous echo to determine the quality of the waveform. Layer thickness is calculated from the spacing between pulse echoes and the velocity of sound in the layer material.
