Title: David M Cook - Innovator in Seismic Data Technology

Introduction

David M Cook is an accomplished inventor based in Corvallis, OR (US). He holds 2 patents that showcase his expertise in seismic data technology. His innovative approaches have contributed significantly to the field, particularly in the areas of seismic sensor data and waveform generation.

Latest Patents

David's latest patents include "Seismic Data Apparatus and Methods" and "Generation of Adjustable Phase Reference Waveform." The first patent provides methods and apparatus related to seismic sensor data. It involves digitally sampling seismic sensor signaling in accordance with a local clock, without synchronization to standardized time. Timestamp data is utilized to synthesize data corresponding to an artificial stimulus waveform. Cross-correlation of the synthesized data with the seismic sensor data yields a correlation result, which can be scaled to the original starting time for the seismic data sampling. This scaled correlation result can be stored in computer-accessible media for further processing or interpretation. The second patent outlines a system for generating a reference waveform. This system includes a first pulse-width modulation (PWM) channel that provides a first PWM waveform with a specific duty cycle and frequency. A second PWM channel generates a second PWM waveform with a different duty cycle but the same frequency. Combinational logic is then used to combine these waveforms, resulting in a phase-shifted reference PWM waveform.
