Conformal Coating’s Effects on Radio Frequency Time: 3:00-3:20 p.m. Faculty Advisor: Dr. R. Pecen Presenters: Jordan Overton & Michael Eichenberger Sponsor/Industry Supervisor: Rockwell Collins, Inc. Dave Burger, Doug Pauls, Dave Hillman, Jennifer McAllister, Mike Davidson, Nicole Hinde. Rockwell Collins uses several different conformal coating types on their circuit cards to protect them from harsh environmental conditions. It is our investigative research that will aid design and manufacturing to use reliable coating types for application. Signal loss will be measured, recorded and analyzed on the various dielectric materials with selected coatings. Four hundred data points are recorded over the frequency range of 150 kHz to 8 GHz using a network analyzer. The data is then analyzed to determine results. GENESIS (General Engineering Network of Electronically Simulated Intelligent Systems) Programmable Power Controller Time: 4:40-5:00 p.m. Faculty Advisor: Dr. Pecen Time: 3:40-4:00 pm Faculty Advisors: Dr. R. Pecen, Dr. J. Zhu, Dr. J. Nie. Presenters: Keith Dahl and Grant Hicok Presenter: Jeffrey J Rick Sponsor: Self-sponsored. Sponsor/Industry Supervisor: Self-sponsored The purpose of the GENESIS project is to design and build a functional and affordable android head. GENESIS was started as a personal project by Jeffrey Rick and has evolved into a class project and the foundation for an affordable, marketable android head. GENESIS is female in presentation and has the ability to respond to voice commands with facial movements and her own voice. While the artificial intelligence is still in a rudimentary stage, it guides the way for further development in AI as well as android technology. The purpose of this project is to design and build a user friendly device that will allow the user to control power usage in various home settings. Overall system includes receptacle box with multiple outlets that can be controlled remotely with a universal remote that activates power to each individual receptacle. There will be designated receptacles that are controlled by a basic stamp that is programmed for a specific timed sequence and there will also be individual receptacles that can be turned on and off instantly for convenience for the user. This device is designed to help control cost of electrical power. John Deere Data Acquisition Conversion Air Pressure HMI Automation Time: 4:00-4:20 pm Faculty Advisor: Dr. R. Pecen Time: 3:20-3:40 p.m. Faculty Advisor: Dr. R. Pecen Presenters: Nathan Cooper & Blake Franzen Presenters: Josh Bradley, Andrew Pei Sponsor/Industry Supervisor: John Deere PEC, Instrumentation Engineering, Mr. Jon Anderson and Mr. Don McCallum Sponsor/Industry Supervisor: John Deere Foundry, Mr. Todd Garris The project consists of developing an HMI (Human Machine Interface) for the compressed air system at the John Deere Foundry where there is no an interactive interface for the compressed air system to give the maintenance personnel information they need to make the job easier in a sense that they will have the convenience of having all the information on one computer. The home screen of our program is going to display the system wide plant pressure and four compressor statuses. Each compressor will have its own display with critical information and statistics. The software used for designing this interface is Factory Talk View Machine Edition by Rockwell Software. A research, design and development project to assist John Deere with moving forward in their test data acquisition systems. This project was brought to us by Jon Anderson and his Instrumentation Engineering team. We needed to find a bestfit solution for John Deere that will incorporate CAN communication technology, proper signal conditioning and provide both expandability and flexibility for future test data acquisition. 2.8kW PV Power System Design and Implementation Time: 4:20-4:40 pm Faculty Advisor: Dr. R. Pecen Presenters: Aaron Spiess, Sultan Altamimi, Mac Russett Sponsors: IAWIND, US DoE DEED Scholarship from Waverly Light and Power, SOAR Grant from CNS. This project includes designing and building a 2.8 kW photovoltaic power system at UNI campus to provide a teaching and research facility on renewable energy areas for students and faculty members in Electrical and Manufacturing Engineering Optical Disc Reclaimer Development Time: 5:00-5:20 p.m. Faculty Advisor: Dr. R. Pecen Presenter: Jacob Smith & Andrew Nyanjenga Sponsor/Industry Supervisor: TurnKey Solutions, Perry Smith Optical discs have been one of the main forms of media storage in today’s world. Their surfaces are however easily ruined. Due to highly valuable content of most users, it is important to devise a way to restore readability to these discs. TurnKey Solutions, the largest media duplication company in the US, were looking for ways to maintain their vast array of master discs. A proposal was made to devise a machine that can restore readability to an optical disc. Using a Complex Programmable Logic Device, the restoration process is sequentially run by VHDL software. The process is accomplished in a three stage cleaning process. The project involves using a DC motor with speed control to spin the optical disc during the cleaning operation, a buffer arm motor is used to run the cleaning arm, a compressor to dispense cleaning fluids and a Hall Effect sensor to track the number of revolutions made by the optical disc. Diesel Engine Emissions Sensitivity to Dyno PID Tun- ing The mission of the Electrical Engineering Technology Program at the University of Northern Iowa is to foster Time: 5:20-5:40 p.m. Faculty Advisor: Dr. R. Pecen Engineering Technology professionals through quality Presenters: Jeff Faust and Jonathan Mueller and application oriented breadth of education and experience to contribute to the advancement of Electrical Sponsor/Industry Supervisor: John Deere Power SysEngineering Technology in support of Hardware, Softtems, Ms. Genevieve Flanagan ware, and Systems Engineering. The objective of this project is to realize and quantify the We greatly appreciate to our senior project sponsors sensitivity of diesel engine emissions to dyno PID tuning and College of Natural Sciences for SOAR grants. during transient testing in a test laboratory. A design of experiments (DOE) was custom designed and run in a test cell at John Deere PEC. Statistical analysis is completed in an emissions test cell. A sufficient amount of test cell data was collected to show that a quantitative relationship exists between different PID gains, engine response, measured emissions, and statistics. The results are analyzed and a “standard” dyno response is developed that will be enhancing JD Dyno PID Tuning operations very positively. pecen@uni.edu jin.zhu@uni.edu hong.nie@uni.edu Time: 5:40-6:00 p.m. Faculty Advisor: Dr. R. Pecen Presenter: Brian P. DeLorbe Sponsor/Industry Supervisor: Self-sponsored. Center for Energy and Environmental Education (CEEE) 11 Auditorium Wireless Interlock System (WIS) Wireless Interlock System (WIS) consists of a wireless breathalyzer module (BM) containing a fuel cell sensor to detect alcohol present in a person, also a control module (CM) wired into the vehicles ignition system controls whether or not a breath sample is need before operating the vehicle. A wireless MCU in the CM directly controls the ignition system of the vehicle. This serves two functions: (1) as a personal breathalyzer and (2) as an interlock for your vehicle. This Wireless Interlock System improves on existing interlock devices already available to consumers by providing a breathalyzer with those two functions. The mobility of the BM prevents long warm-up times during cold weather and can be used in situations away from a vehicle to monitor %BAC before trying to operate a vehicle. Previously breathalyzers and ignition interlock systems have been two completely separate devices. Now one breathalyzer can perform both functions. Allowing a user to program the CM provides a less intrusive and more user friendly device.
