Title: Elbert N Shawhan: Innovator in Borehole Data Transmission

Introduction

Elbert N Shawhan is a notable inventor based in West Chester, PA (US). He has made significant contributions to the field of data transmission, particularly in the context of borehole telemetry systems. With a total of 3 patents to his name, Shawhan's work has advanced the technology used in drilling operations.

Latest Patents

One of Shawhan's latest patents is focused on data transmission in a drill string. This innovation allows data to be transmitted through a drill string using acoustical energy. The method involves transmitting an acoustical signal for a predetermined interval and then ceasing transmission to represent binary states. This technique effectively combines transmission and cessation of the signal in binary sequences that represent borehole data.

Another significant patent by Shawhan is a bit identification system for borehole acoustical telemetry systems. This system identifies binary bits represented by pulses through circuitry that integrates a signal with a sequence of such pulses. The integrator level is stored and discharged in synchronization with the bit pulse rate, ensuring that only bona fide signal bits are recognized, while false signals generated by background noise are filtered out.
