Title: Ralph A. Landrum, Jr.: Innovator in Seismic Technology

Introduction

Ralph A. Landrum, Jr. is a notable inventor based in Houston, TX (US), recognized for his contributions to seismic technology. He holds a total of 4 patents, showcasing his innovative approach to solving complex challenges in the field of geophysics.

Latest Patents

One of his latest patents is titled "Simultaneous Performance of Multiple Seismic Vibratory Surveys." This invention presents a method for conducting several vibratory seismic surveys at the same time. A variety of vibratory sources send signals into the earth, with each source transmitting the same signal but with a selectively shifted offset phase for successive transmissions. This design allows for effective data recovery through processing. Another significant patent is "Adaptive Preset Force Level Control for a Seismic Vibrator." This invention involves a seismic vibrator that is controlled by an input sweep signal. The control signal, which is based on the output force level of the vibrator, modulates the sweep signal to maintain the output force level within a range that prevents ground decoupling. An adaptive preset signal is utilized at the beginning of a sweep to enhance performance.
