IntroductionOverview
• 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
33
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

Data Acquisition
Data Acquisition Has Two Main Parts:
1. Data Collection
2. Data Organization and Presentation
55
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!
66
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 ???
77
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

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
Database
Table

This Funciton opens the Database Connection
Requests a List of Fields in the Requested Table
Inserts Data Into the Selected Fields
Closes the Database Connection

Web Interface
• Price• All open source software….FREE!• Constructed and maintained by Undergraduate Students
• Security• Users have controlled access permissions to keep sensitive
material contained• Necessary for International Traffic in Arms (ITAR) and Non-
Disclosure Agreements (NDA) agreements• Speed
• Data is uploaded automatically after acquisition allowing for near instant data presentation to sponsor
• Accessibility• Users only require an Internet connection to view Data• Interface is understandable and easy to use
Our Website Has…
1111
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

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
1313
Web Interface
• CSV text files can be imported
• Old data or custom data can be entered
Import Data function allows for alternate data insertion

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
