Project Summary
Principal

Mr. Marshall is Owner, Operator and Founder of TorsionTec. He has had a long and diverse career in Electronics, Electromechanical, and Computer technology development. 

A gift for technology was evident even in elementary school and at the age of 17 he graduated from high school as Class Salutatorian with Matriculation and a Scholarship to study Electrical Engineering at the University of Calgary. His outstanding academic achievments earned him several more scholarships and the prestigious distinction of working for Canada's Defense Research Establishment Suffield as a designer in their Electronics Labs through the DRES coop summer student program.

At DRES Mr. Marshall's passion for technology development was realized for the first time in a career oriented institution. In four months as a coop summer student he developed data logging systems for use in the military.

After graduating with honors in Electrical/Electronic/Computer Engineering he quickly became a guru in large mainframe computer systems used for Seismic and GIS data processing. 

At the Alberta Research Council and Civil Engineering Hydrology Lab on the University of Alberta campus in Edmonton, he used the early kit computers as microcontrollers to develop data logging and servo-control systems for various projects including; an automated three-dimensional flume-based probe positioning & measurement system, an oil-sands heavy-oil bitumen processing pilot plant, an automated coal gasification prototype, a flywheel-based concrete tensile strength tester, and an automated precision micrometer lead-screw tree ring measurement system for Paleontology research.

Back in Calgary he went to work for a leading well log and seismic data services company where he was responsible for development of several "leading-edge" electronic, microcontroller, and software systems, used internally in capturing, organizing and providing data services, as well as being resold to many of the major Oil & Gas exploration companies worldwide. As Research & Development Manager, Mr. Marshall conceptualized, analyzed and coded much of the software for these systems, as well as coordinating the efforts of other team members. Some of the projects included; PBD (Paint Brush Digitizer) - a scanning system that automatically recognized oscillograph curves in oil well log images, Farmland Valuation System - an innovative land mapping and database system used extensively by government agencies to automate the land valuation process, Sonibase - a geological well log data delivery system, Logbase - a full well log management and data delivery system,.and Geowell - a map-based complete oil well data management and data delivery system.  After a corporate takeover, Mr. Marshall started TorsionTec - high torque generators/motors, and AcreMap - land valuation software.
