Title: Joseph L Portman, Jr: Innovator in Piezoelectric Technology
Introduction
Joseph L Portman, Jr. is a notable inventor based in San Antonio, TX (US). He has made significant contributions to the field of fluid viscosity measurement through his innovative work on piezoelectric devices. His expertise and creativity have led to the development of a unique patent that enhances the accuracy of viscosity determination.
Latest Patents
Portman holds a patent for a piezoelectric viscometer. This device utilizes a piezoelectric driver that is resiliently attached to a base, which is isolated from vibrations. The system includes a piezoelectric receiver and a probe that move in response to the motion of the driver. The receiver generates an electric signal proportional to the system's motion. The viscometer operates near the resonant frequency of the receiver and probe. By applying an oscillating sine wave voltage, such as 140 hertz, to the driver and immersing the probe in fluids of known viscosities, calibrated outputs are obtained. This innovative approach allows for the determination of unknown viscosities by comparing them to known standards.
