1. Instant Data Gathering, Processing, and Display for Industry Sponsor Using Interfaced Software Packages By Tracey Windley and Jasper Nance Professor Herb Hess Kevin Buck 2006 ASEE Annual Conference 6/19/2006

2. Introduction Overview • Microelectronics Research Communications Institute (MRCI) Background • Data Acquisition Problems in the MRCI • Data Formatting and Storage • Data Retrieval and Presentation • Data Acquisition Solutions • LabVIEW Instrument Automation • Data organization with a MYSQL Database • Data Presentation with the MRCI Data Website • Future Work & Summary

3. MRCI Background • The MRCI is a multidisciplinary research center that supports research from many different departments and programs • Electrical Engineering • Computer Science • Chemistry/Chemical Engineering • Bio-Systems Engineering • Computer Engineering • Mechanical Engineering • The MRCI develops technologies in microelectronics, power electronics, microwave ferrite research, battery development, intelligent control, computer security, communications systems, and neural networks. • MRCI has received several million dollars from governmental and private sources alike over the past 9 years. • NASA EPSCOR • Navy • BOEING • Homeland Security • BAE Systems • Schweitzer • Honeywell • National Science Foundation • At present, MRCI supports 43 undergraduate researchers, 44 graduate research assistants, 11 irregular help graduate researchers, 4 post-doctoral researchers, 3 R&D engineers, 4 research engineers, and 1 scientific aide. • Visit http//:www.mrc.uidaho.edu for more information

4. Data Acquisition Data Acquisition Has Two Main Parts: • Data Collection • Data Organization and Presentation

5. Data Collection Problems at MRCI • The MRCI Collects a lot of Data • High Researcher Turnover rate can make testing difficult • 640 transistors tested for Boeing last summer • Measurement Error • Novice researchers can make mistakes during measurement. (and Experienced ones too!) • Long periods of data collection may cause researchers to become inattentive • Time Costly • Data collection can be costly and labor intensive. • Solution • Automation!

6. Problems With Data Organization and Data Presentation • Poor data formatting could result in data loss or corruption • Solution • Data must be recorded and stored uniformly • Data must include information about the conditions of the test and about the Researcher • Data must be easily searchable • Data must be easily presentable to project sponsor and supervisors ???

7. Data Gathering System We Built a System… • That is easy to use and understand • Necessary for new researchers and sponsors alike • That is fully automated • Huge time and money saver • Major Productivity win • That enforces uniform data formatting • Helps solve problem with researcher turnover rate • Improves data organization • That Stores data in an environment that is easily accessible and allows for easy Data presentation • Provides fast turn around time from data collection to data presentation

8. Data Gathering System Diagram • LabVIEW Controls Data Acquisition and Data insertion into the Database • Website allows user access to the database through the Internet MYSQL Drivers LabVIEW Website

9. LabVIEW • Requires little syntax or previous coding experience! • Graphical Coding Language Developed by National Instruments • Uses boxes and wires to represent functions in a flowchart like form • Allows user program control using buttons and Textboxes on the front panel • Comes with Toolboxes for MYSQL Database communication, Signal Processing, and GPIB Instrument Communication Protocol Why LabVIEW? Its EASY!

11. Web Interface • MYSQL • MYSQL is an open source database software with built in optimized search and table joining capabilities • PHP • PHP Code allows for page creation on-the-fly that can respond to user input and database interaction. • Built in MYSQL Support • They are Open Source

12. Web Interface • Users can create graphs from hundreds of separate traces Website allows for fast Data access and Presentation • Easy interface for Data searching and Retrieval

13. Web Interface • CSV text files can be imported • Old data or custom data can be entered Import Data function allows for alternate data insertion

14. Summary and Future Work • Summary • Solutions to common data acquisition problems • MRCI Data Acquisition System is a huge time and money saver and productivity win • Website Interface was constructed by undergraduates using free open source software • Website has the ability to provide near instant access to the data via the Internet • Future Work • Constant improvements to the Website interface
