Title: Innovations of Kenneth R Goodman

Introduction

Kenneth R Goodman is a notable inventor based in LaPorte, Texas, who has made significant contributions to the field of telemetry systems. With a total of six patents to his name, Goodman has developed innovative methods that enhance communication between surface modems and downhole measuring equipment.

Latest Patents

One of Goodman's latest patents is a method and apparatus to train a telemetry system for optimal performance. This system utilizes a periodic pseudorandom training sequence to initialize an adaptive digital FIR filter-equalizer, facilitating effective communication without requiring changes to the normal logging configuration or special operator intervention. In the training mode, an electronic source in a downhole sonde transmits a predetermined training sequence to a surface modem via a cable. This continuous transmission allows the surface modem to acclimate to the characteristics of the multiconductor cable, enabling accurate data interpretation despite potential attenuation, noise, or distortion. Once trained, the system operates in an operational mode, where the sonde transmits data corresponding to downhole measurements, and the filter-equalizer continually adjusts itself for optimal data reception.

Another significant patent is for a high data rate wireline telemetry system. This system features an encoding mechanism located downhole that works in conjunction with surface-based decoding equipment. The encoder converts serial data into NRZ symbols, then into duobinary code of seven levels, and finally into quadrature modulating signals on a complex carrier. The surface decoder receives these signals, forming in-phase and quadrature components while removing intersignal distortion and intersymbol smearing, which significantly enhances the telemetry ratio.
