TCU Engineering

 This presentation encompasses the principal topics in instrumentation systems:  sensors, signal conditioners, data digitization and filtering, and validation of the recorded data.  It begins with a thought evoking discussion as to why we measure and subsequently defines the measurement process.  A brief introduction to transducer physics is provided along with the historical evolution of transducer signal conditioning.  Rules for data digitization are provided along with guidance for data filtering.  Examples of bad data identified through the data validation process presented are shown.  The participant is left with a checklist to assist him/her in understanding measurement system design.


Since arriving at TCU, Dr. Walter’s principal focus has been the 2-semester Capstone Senior Design Program.  This electro-mechanical design sequence has received annual support from Aberdeen Proving Grounds (U. S. Army), Alcon Laboratories, Bell Helicopter Textron, Endevco Corporation, Lockheed-Martin Aeronautics, Naval Surface Warfare Center, Oncor, PCB Piezotronics, Rockbit International, Stone Innovations, and U.S. Army Engineer and Development Center Waterways Experiment Station (WES).  Dr. Walter also currently teaches in the solid mechanics and advanced vibrations areas and has developed TCU’s solid mechanics and structural dynamics labs.   In addition, through TCU’s Extended Education and Engineering Departments, he teaches a continuing education program in Measurement Systems Engineering, which has been presented throughout the U.S., Canada, and overseas.
  Dr. Walter has numerous publications, has served and chaired DoD and DOE committees, and consults extensively in the aerospace and defense industries.  He is a member of ISA (25+ years: Aerospace Systems and Test Measurements Divisions), Society of Experimental Mechanics (also 25+ years: Sensors and Instrumentation, Structural Test, and Strain Gage Divisions), and American Society of Engineering Educators (12 years: Instrumentation and Design Divisions). He is a licensed professional engineer in the state of New Mexico.
  In 2008 Dr. Walter received the Lifetime Achievement Award from the Shock and Vibration Information Analysis Center (SAVIAC).  The Center, first formed in 1946, is a central information resource for Government activities, contractors, and academics concerned with structural dynamics design, analysis, and testing; and shock physics and weapons effects.  It is a jointly-funded activity sponsored by the Army, Navy, Air Force, Defense Threat Reduction Agency, and the Department of Energy laboratories.
