“Prototype MGG Pyrotechnic Auto Loader”
This team will develop a electro-mechanical machine that autoloads pyrotechnic material into Autoliv’s Micro Gas Generators (MGG) for prototype use. You will be provided with a material that has equivalent handling characteristics (particle size, density, etc.), but NON-pyrotechnic for the project development. These MGG’s are the pyrotechnic ‘engines’ that are then install into various pyrotechnically operated devices such as seat belt pre-tensioners, hood-lifters, and airbag systems.

“Wireless electrical stimulator”
Clinical neurophysiological testing uses an electrical stimulator to depolarize nerves for evaluation of the integrity and health of the nerve, associated muscle, or motor end plate. The stimulus is synchronized with a data acquisition system to allow measuring conduction velocity. An example is testing for Carpal Tunnel syndrome where the median nerve at the wrist is stimulated and the APB muscle (thumb muscle) is monitored. The Cadwell Stimtroller has an active and reference electrode, 5 programmable buttons, and a rotary scroll wheel for changing intensity. The stimulus is generated in the base unit, and the controls are all ‘fly-by-wire’ inputs to the stim generator. The proposed project is to implement a wireless stimulator to eliminate the cord running from the testing instrument to the stimulator. The wireless equivalent would have similar features as the wired predicate, but would, in addition, need to generate and control the high voltage needed for stimulation, and would need to communicate with and stay synchronized to the base unit.

“Nanophotonic sensor development”
Moxtek makes nanophotonic structures for consumer and military electronics applications. The purpose of this project is to explore the application of these structures to methods in biosensing. One application is in the real-time detection of molecular binding, for which a microfluidic flow cell is coupled to a nanophotonic structure, and changes in spectral light transmission are measured as sample is flowed across the sensor surface. Another application is in detecting molecular fingerprints using Raman scattering, which requires high resolution optical spectroscopy and analysis of spectral peaks. The direction of the team will be based in part upon the background and interests of the students.
Students must have taken or take ECE 5410.

“Pressure Transducer Cal-Com Device”
Quartzdyne manufactures the industry‐standard quartz downhole pressure transducer and hybrid electronics for the oil and gas industry. Calibration of the instrument can take 5‐7 days under changing conditions of pressure and temperature to characterize the entire range of each device. This is done in stirred oil baths and with deadweight pressure generators. A single bath can hold up to 20 transducers and the signals from these transducers are muxed to a single point so that the frequencies can be counted with high precision counters. The goal of this project is to distribute precision counters in a “single piece” fashion so that each transducer has a “cal‐com” device. This device will be self contained, will log data to a database, and will respond to commands from the calibration supervisor computer. This project will simplify data acquisition during the process of calibration, allow constant monitoring of each device under test (looking for quality issues) and allow other engineering tests to be completed faster.

|Reliable Controls Corp.
“21st Century Automation for Heavy Industry”
The aim of the project is to find the optimal way to drive a rock crusher. The team will be divided into two groups to develop competing electrically- and hydraulically-driven systems. Reliable Controls will provide roll crushers and all other equipment needed. The students will specify, design, and implement control systems to drive the electric and hydraulic actuators. State-of-the-art instrumentation and control hardware will be used to automate and supervise these systems, with the goal of identifying which system is more energy-efficient, provides the highest reliability, and delivers the best power/torque combination given the objectives. Reliable Controls expects students to be driven, creative, passionate, and self-motivated in order to bring an innovative solution to a critical industrial challenge.
Candidates should be willing to travel regularly to Reliable Controls at 999 Murray-Holladay Rd to perform experimental work. ECE students must have taken or be taking ECE 3510 and ECE 3600.

“Teaching “The Duck” to Fly in Utah”
The daily solar PV power generation curve is well known. It rises to a peak at solar noon, and returns to zero at sunset. Lesser known is what this generation pattern does to the electric utility’s daily generation curve at high solar PV penetration levels. This curve is sometimes called “the duck.” The problem revealed by the duck family of curves is the high non-solar generation resources and ramp rates required of the utility in the summer just before the sun goes down when customer load is at its peak and solar is quickly waning. There are many options for flattening out the non-solar generation required through a hot summer day. This is sometimes called, “teaching the duck to fly.” Each option has its benefits and costs.
This team will: study possible options (both load and generation) for teaching the duck to fly; study Utah cultural, political, environmental and economic factors related to generation and load; generate a software model that captures these factors; and recommend and report on the optimal model that will teach the duck to fly in Utah.
Students must have taken or take ECE 3600 and ECE 5610 or 5620.

“Electrical impedance tomography data acquisition”
With America’s aging infrastructure, it is important to monitor our bridges, buildings, and aircraft, among other structures, for signs of degradation that may lead to their failure. Electrical impedance tomography (EIT) is a spatially distributed sensing methodology that is used to determine the electrical conductivity across a spatial region in 2D or 3D by measuring potential across multiple electrode pairs in response to an applied current. Changes in conductivity can be used to indicate a complex strain distribution in a part, an impact location of an object colliding with an aircraft wing, or the penetration of a bullet through a soldier’s body armor. In this project, the team will continue with the development of a dedicated data acquisition unit for EIT measurements. The system should be capable of taking voltage measurements for up to 32 EIT electrodes (896 total voltage measurements) in less than 1 second. The data acquisition unit should be interfaced with a GUI in either MATLAB or LabView.

“Emergency portable landing zone system”
This project is to develop a rapidly-deployable landing zone lighting system for use by emergency first-responders. Often an emergency situation requires helicopter landing and takeoff, but ground and weather conditions are not always amenable to this response. The landing zone system consists of six independent “beacon” modules that are laid out in a specific spatial pattern and emit high-intensity LED light. The modules must be synchronized to implement a specific blinking pattern that is recognizable by the pilot.

“Tattoo Antennas for Implantable Medical Devices”
Implantable medical devices touch virtually every major function in the human body. Cardiac pacemakers and defibrillators, neural recording and stimulation devices, cochlear and retinal implants, etc. Wireless telemetry for these devices is necessary to monitor battery level and device health, upload reprogramming for device function, and download data for patient monitoring. Antennas are inevitably one of the largest if not the largest component of the telemetry communication system and are generally mounted on or in the implanted battery pack, usually in a body cavity. This limited real estate significantly constrains the performance of implantable antennas and results in substantial power loss in the body. Lost power means lost transmit distance and lost battery life.

“Topics in semiconductors”
1) We use deep level transient spectroscopy (DLTS), a time domain technique, and admittance spectroscopy, a frequency domain technique to measure traps in solar cells. Our current setup only allows one cell to be measured at a time but our samples typically have 6-7 cells. Keithley instruments is interested in helping us parallelize the measurement by loaning a switch matrix for testing and demonstration. Duties would include adding wiring to our cryostat for multiple samples then integrating using MyDAQ and Labview a LCR meter and the switch matrix for admittance spectroscopy and the switch matrix, a lockin amplifier, and a programmable DC voltage source for DLTS as well as developing a data analysis program in Matlab. 1-3 students
