The Boeing Company
GPS IIF Control Segment Computer Simulation of the GPS Ground Network
Liaisons: Darryl Nakata ‘86, Ryan Ripken
Advisor: Michael Erlinger
Students: Christopher Dahlberg, Christopher Erickson, Andrew Kim, Marshall Pierce (PM)

To maintain accuracy, GPS satellites require regular corrections to their broadcast orbital parameters. An extensive network of ground antennas and control stations throughout the world periodically updates the satellites' orbital parameters, and transmits the updated information to each satellite. Currently, this process occurs at least once a day. Raising the update frequency would increase the accuracy of GPS, but would increase network traffic within the ground network with unknown consequences. To test the impact of such changes on network load, the Clinic team has developed a simulation framework using inexpensive PCs to represent the various nodes in the ground network.

Rain Bird Corporation
Microclimate-Specific Sprinkling System
Liaison: Jason Alderman
Advisor: Joseph King
Students: Tyler Jank (TL), Renee Campbell (S), Alice Clifton (F), Donya Frank, Eugene Hsueh, Bart Oegema (S), Nate Schlossberg (F)

The goal of this project is to build a smart watering system to reduce water wastage during landscape irrigation. Traditional sprinkler systems are designed to water for the driest area, which means all other areas are over-watered. Rain Bird has requested that the team develop a system to solve this problem by adjusting for the microclimates within an irrigation zone. Our system would adjust for each microclimate by keeping on or turning off each sprinkler based on the moisture level in the area that each sprinkler covers. In order to develop this system the team has designed a wireless moisture sensor that transmits a moisture level to a central controller. That controller is attached to each valve and will cut off power to the sprinkler valve if the microclimate has been sufficiently watered.

Space Systems/Loral
Vibration Damping for Satellite Momentum Wheel Assemblies
Liaisons: K.C. Jiang, John Kesapradist
Advisor: Ziyad Durón ‘91
Students: Rami Y. Hindiyeh (TL), Ruben Betancourt, Ryan Ellis (F), Joshua Hwung, Jakob Spjut (F), Todd Taniguchi (S)

Momentum wheels are an efficient means to re-orient a satellite in orbit without using thrusters, which consume fuel from the satellite's limited supply. In order to have a significant influence on a satellite's orientation, however, a momentum wheel must be spun at very high RPM, often creating vibrations that have an adverse effect upon a satellite's pointing accuracy. With this in mind, the SS/Loral Clinic team has employed numerical and empirical methods to characterize the composite assembly used to mount momentum wheels to SS/Loral satellites and explore damping techniques for this assembly.

The LLUMC Clinic team is to provide a sequential alignment and position verification system that will ensure and maintain the proper position and orientation of the proton beam with respect to the target area in the patient’s brain.

METROPOLITAN WATER DISTRICT OF SOUTHERN CALIFORNIA
High-Recovery Membrane Processes for Surface Water Desalination
Liaisons: Sun Liang, Dr. Chris Gabelich
Advisor: Donald Remer
Students: Clare Schoene (TL), Long Tien Thang, Brian Yoxall, Neal Okumura

Our team investigated increasing the water recovery of a membrane desalinating unit by combining the high salt rejection properties of reverse osmosis (RO) membranes with the high flux (production) properties of nanofiltration (NF) membranes. Using both membranes, the overall water recovery can go above 90% by tailoring the salt passage within the system. We developed models simulating hydraulic and physicochemical conditions within the RO/NF system, which are currently not available in commercial modeling software.

MINIMED, INC.
A New Design for the Medipad Insulin Infusion Pump
Liaison: John Livingston
Advisor: Jim Rosenberg (Fall), Clive Dym (Spring)
Students: Anthony Hawkins (TL), David Hopkins, Joshua Switkes, Roy Park

MiniMed has developed a disposable insulin pump for the treatment of Type 2 diabetes. Because this pump is a medical device, it must be sterilized with radiation. This radiation damages the electronics inside the pump. The team has been asked to redesign the pump apparatus so that the electronics can be easily inserted by the patient after the sterilization process.

Advisor: David Harris
Students: James Speros (TL), Ryan Stuck, Taufiqul Kazi, Kevin Ota

Opto22 needs to replace two legacy integrated circuits due to cost, availibility, and performance constraints. One implements a subset of the ARCNET network communication protocol. The other performs a variety of monitoring and control functions for 32 optically isolated digital lines. The functionality of these chips has been written in synthesizable VHDL for FPGA implementation

OREGON MEDICAL LASER CENTER
Automation of Clinical Laser Tissue Welding
Liaison: Kenton Gregory
Advisor: Sanjay Joshi
Students: Elizabeth Johansen (TL), Benjamin Martin, Brooke Basinger, Karen Ahle

Laser tissue welding is a method of joining tissues together with no stitches, staples or sutures. It is still in the developmental phase, and current tissue welding techniques are highly dependent on the individual skill and technique of the operating surgeon. For any further advances to occur, the scientific community needs a more reproducible way to study tissue welding. Oregon Medical Laser Center has proposed that we design and build an automated laser guidance system that will attempt to eliminate human variation and error from the tissue welding process, thus yielding a safer surgical procedure.

RAIN BIRD
Mechanically Timed Pilot Valve for Control of Golf Course Irrigation Sprinklers
Liaison: Mark Ensworth
Advisor: Philip Cha
Students: Jon Hebreo (TL), Leandro Lopez, Laura Nelson, Amy Gishifu

The Rain Bird team has designed, developed, and tested a mechanical timer and pilot valve for manual control of an Eagle rotor sprinkler for golf courses. The system is entirely mechanical, independent of an electric power source. The timer has been developed by modifying a household egg timer, and the valve was designed to allow or stop the flow of the water by redirecting the water through the use of o-rings.

ROCKWELL COLLINS

Liaison: Jay Cardon
Adivisor: Carl Baumgaertner
Students: Michael Aung (TL), John Benediktsson, Clement Mounier, William Durley

Next generation in-flight entertainment systems will provide commercial airline passengers with access to music, movies, and games on-demand for upwards of 400 independent users. Rockwell Collins requires a portable high-speed loading system to update the digital content at speeds up to 400 mbps, allowing complete program reloading in a half-hour aircraft gate time. To deter piracy, the loading system incorporates content encryption and decryption methods that meet MPAA and RIAA industry standards. SUN MICROSYSTEMS LABORATORIES Asynchronous FIFO Buffer Demonstrator Board Liaisons: Ian Jones, John Gainsley, Jon Lexau Advisor: Ruye Wang Students: Nicholas Bodnaruk (TL), Zehao Chang, Andrew Ingram, Sean Kao In modern digital systems, synchronous (clocked) circuitry is the standard method of design. There are many situations, however, where a digital system may benefit from an asynchronous (clock-free) component. Sun Microsystems Laboratories has tasked our Clinic team to design and implement an asynchronous FIFO buffer demonstrator board that will serve as an educational tool to teach and explain the benefits of asynchronous circuit designs for high-speed data communication. TEXAS INSTRUMENTS Implementation of a GPS Searcher for 3G Cellular Technology Liaisons: Edwin Park, Karim Abdulla Advisors: David Harris Students: Fernando Mattos (TL), E-Hwa Chung, Drakos McGuire, Jeffrey Miller The Clinic team developed a VHDL searcher that correlates GPS signals and reports the available satellites to a CPU. The team modified Texas Instruments’ (TI) searcher for CDMA base stations in order to reuse the already existing hardware as much as possible. The first step of the project was to focus on developing mathematical models for GPS signals and the searcher, and to set up the interface equipment necessary for the hardware implementation. Finally, the team modified TI's VHDL code to support GPS satellite searching. After initial software simulation, the team integrated the VHDL code into FPGAs for hardware demonstration and for testing with a larger amount of test vectors. TREX ENTERPRISES Internet-Based Advanced Camera Positioning and Tracking System Liaisons: Dr. Peter Martin, and Michael Rodby Advisor: Anthony Bright Students: Michael Tapper (TL), Arastoo Moradi, Doonin Park, Jason Imada The Clinic team has designed and implemented an internet-based advanced camera positioning and tracking system for Trex Enterprises' high-resolution digital camera. While the camera's video streams to the web in real time, the web user can control the camera's pan and tilt position and its XY translational position. The tracking function allows the camera to recognize a laser point target and follow the target's movement within the camera's workspace.

APPLIED BIOSYSTEMS Automatic Threshold Setting for Quantitative Polymerase Chain Reaction Liaison: Kenneth Livak ’74 Advisors: Lesley Ward Consultant: Mary Williams Students: Cameron McLeman '02 (TL), Tae Jensen ’02, Justin Lyon, Bryan Tysinger Quantitative Polymerase Chain Reaction (PCR) is a process used to amplify a small unknown amount of DNA and determine how much of the given DNA species was initially present. This calculation depends on the selection of an appropriate threshold fluorescence value in the middle of the exponential region of the reaction’s amplification plot. Our task is to automate the selection of this threshold. We use linear regressions and Gaussian probability distributions. ETEC SYSTEMS, INC., AN APPLIED MATERIALS COMPANY Methods to Improve Estimates of Effective Maximum Error for Laser Lithography Etching Liaison: H. Christopher Hamaker ’75 Advisors: Henry Krieger, Gregory Levin, Michael Moody Students: Jennifer Patrick (TL), Neville Khambatta, Marco Latini, Ian Schempp Etec Systems produces laser lithography equipment used to create photomasks needed for the manufacture of semiconductor chips. Since the etching process is not exact, there is some probability that any single geometry on a chip will be defective, which renders the entire wafer useless. This project investigated methods to improve estimates of the expected percentage of photomasks that will meet quality control criteria. These methods include investigation of certain parametric distributions to better fit machine calibration data, and the use of bootstrap techniques to improve the estimates of key parameters. FAIR, ISAAC AND COMPANY, INC. Assessing Consumer Preferences to Aid Online Purchase Decisions Liaisons: Lisa Buonpane, Ralph Keeney, Robert Oliver Advisor: Darryl. Yong Students: Natan Bershtel (TL), John Chou, Claire Launay, John Lu Most web sites that help consumers decide between product offerings don’t explicitly incorporate preferences and tradeoffs between multiple, often conflicting, goals. In an effort to make e-commerce more personalized, our team, together with Fair, Isaac and Co., Inc., has developed two sites that help users make car-buying decisions. The first is a direct implementation of Utility Theory, while the second is based on the method of Even Swaps. SPACE SYSTEMS/LORAL Optimization for Low-Thrust Orbit Raising Liaison: Glenn Santiago Advisor: Andrew Bernoff Students: Tyson Macdonald (TL), Kylie Bryant (Fall), Matt Gedigian, Jay Trautman, Alex Wilkins Space Systems/Loral is researching the use of ion propulsion to more efficiently raise newly launched satellites to their final orbits. However, as ion propulsion yields thrusts on the order of 1/1000 that of traditional chemical engines, the time of orbit transfer is significantly extended. Our goal is to develop a software package that will optimize (for time and fuel consumption) the use of low-thrust engines for satellite orbit raising.
