Title: Innovations of Michael A. Corrigan
Introduction
Michael A. Corrigan is an accomplished inventor based in Carrollton, Texas. He has made significant contributions to the field of geophysical services, particularly through his innovative patents. With a total of two patents to his name, Corrigan has demonstrated a commitment to advancing technology in seismic applications.
Latest Patents
One of Corrigan's latest patents is the "Piezoelectric seismic vibrator with hydraulic amplifier." This invention utilizes a hydraulic system to amplify the longitudinal displacement resulting from the application of voltage to a stack of piezoelectric elements. In this design, the piezoelectric elements are mounted on a power piston that acts upon a high bulk modulus incompressible fluid, such as mercury. The drive piston, which has a smaller cross-sectional area than the power piston, allows the pressure within the fluid system to amplify the longitudinal displacement of the piezoelectric elements. This movement is then coupled to the earth to generate seismic waves. Another notable patent is the "Enclosure for suppression of air-coupled noise produced by seismic." This invention addresses air wave noise caused by a vibrating baseplate on a seismic vibrator by employing passive sound absorption techniques. The design features a rigid, lightweight enclosure that remains isolated from induced ground vibrations, effectively reducing or eliminating noise.
