Title: Herbert M Berall: Innovator in Material Properties Analysis
Introduction
Herbert M Berall is a notable inventor based in Bethesda, MD (US). He has made significant contributions to the field of material properties analysis, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents is titled "Method to determine the shear absorption of a rubberlike material." This invention involves directing acoustical energy at a viscoelastic material and sampling the backscattered signals that result when compressional waves propagate through the material. The backscattered signals are converted to a resonance amplitude versus frequency domain, allowing for the determination of the shear absorption of the viscoelastic material based on the frequency and the half-width of the resonance peaks.
Another significant patent is "Apparatus and process for determining the composition of fluid-filled." This invention provides an apparatus and method for analyzing the material properties of a fluid contained in a cavity inside a solid. It involves examining the resonances in the amplitude of elastic waves scattered by the cavity. The resonance positions and their widths are utilized to determine the sound speed and density of the cavity filler, extracting all necessary information about the material composition from the high-frequency asymptotic region.
