| Feedback Controlled Brushless DC Motor with Personal Electric Vehicle Application
In this project, the students learn how brushless DC motors have made personal electric vehicles (PEVs) possible, and calculate how much using a PEV instead of an automobile for some of their daily driving can impact their production of carbon dioxide, based on United States driving patterns. In the laboratory, students build a brushless DC motor using three different control methods, based on a reed switch, a Hall effect sensor, and optoelectronics, respectively. In the process, students learn about motors, and compare the components used for control in terms of their reliability.

| Design of a Guitar Tab Player in MATLAB
In this project work with several MATLAB programs to look at the effects of frequency and modeling of signals. The project has two models. In the first module, the students use several MATLAB scripts to discover the effects of sampling, the frequency spectrum of signals, and the modeling of a harmonic signal such as that of a guitar string.
In the second module, the students make use of the modeling efforts of the first module to implement a realistic guitar tab player.

| Microcontroller-based Smart House for Improved Energy Efficiency
In this hands on Real World Engineering project the students will program a simple microcontroller to measure temperature and control functions such as heaters or coolers in a prebuilt smart house. The house is made of a foam shell electric heater, thermoelectric air conditioner and an attic fan with vent.

| Water Desalination via Energy-Efficient Capacitive Deionization (CDI) Technology
The project focuses on the new desalination technology for brackish water - capacitive deionization (CDI). Basics of electrostatics, engineering instrumentation and measurements, and design cycle are introduced. The students will assemble and test a functioning low-power, portable water desalination device.

| Remote Surgical Robotics: Control Systems and Human-Machine Interfacing
This Real-World Engineering Project focuses on optimizing a prototype remote surgical robot which has force-feedback capabilities. The objective is to detect the surface of a gelatin brain by tactile perception through the robot. Students explore the tradeoff between sensitivity and range while considering human factors as design constrains.

| Vehicle Passenger Safety: Exploring Whiplash Protection Systems
In this Real World Engineering Project, students will design and evaluate an active head restraint system.
-Learning about whiplash injury, and characterizing a physical model of the human head-neck system.
-Evaluating the physical model in the context of neck injury testing, and designing a head restraint which can limit head movements during a collision.
-Characterizing a motor and specifying commands which can move the head restraint appropriately when an impact occurs.
-Evaluating a sensor which will activate the motor before an impact occurs.
-Testing the ability of the entire active head restraint system to limit head motion during a simulated rear-end collision.

| Birth Weight Measurement in Midwifery and Mobile Health Care Delivery
Child birth is one of the most fundamental events in human existence. A key indicator used in the assessment of a baby after a successful birth is the baby's birth weight, as well as the baby's weight in subsequent checkups. Underweight babies have a demonstrated higher rate of mortality and are at high risk of developing a number of serious medical conditions. Identification of risk factors associated with birth weight is, therefore, an important task in post-term child healthcare provision. In this Real World Engineering Project, students are asked to design and construct a mechanical or electromechanical system to measure the weight of a baby immediately after birth and at discrete intervals representing growth over a two month period.

| Software Engineering: Public Service Announcement Movies Made with the Alice Programming Language
In this hands-on project students will develop stronger teamwork skills; create an animated PSA using Alice, a visual programming language; learn to use technology for mass communication and also receive an introduction to computer programming; put in practice the engineering design process, and have the opportunity to contribute to society by raising awareness to an important issue.
This software engineering project is centered on the idea of developing public service announcement movies with the Alice programming language. The proposal has emerged from the application of this project six different times in the context of an introduction to engineering course. This past history proved that the project is effective in teaching first-year college students the fundamentals of object-oriented programming in the context of the engineering design process.

| Coping with the Emerging Energy Demand for Charging Plug-in Electric Vehicles
In this hands-on project, student teams will be engaged to cope with the very hot real-world problem arising from the increasing demand for charging Plug-in Electric Vehicles from the electrical energy distribution grid. By means of MATLAB simulations, each team will analyze the effect of multiple quasi-contemporary charging requests on the electrical grid, hence discovering how, as the number of users to be charged increases, either the grid collapses or the user requests may not be entirely fulfilled. The class will discover how smart energy dispatching strategies and smart battery charging methods may mitigate or completely overcome the discussed problems. The class will also be asked to reflect on how the traditional “dumb” grid infrastructure should be modified to allow each proposed solution to be really implemented, finding out the necessity of developing a smart grid capable of interacting with vehicles.

| An adjustable movement-triggered switch access system for people with disabilities
In this project using an accelerometer, a relay and some basic analog signal processing circuits, students will develop a movement-triggered (tilt) switching system that can be used as a piece of assistive technology (AT) for people with disabilities. As a basic illustration of the concept students will use this switching system to turn on and off a simple battery-operated device such as a radio, fan, etc.

| Image Processing Algorithms for Identifying the Gulf Oil Spill
The Gulf of Mexico oil spill between April 20 and September 19, 2010 was the largest offshore spill in U.S. history. Computer algorithms need to be developed to map oil contaminated areas. In this project students are asked to design image processing algorithms to locate and map oil spills on MODIS satellite images and implement the algorithms in Java-based software application. MODIS satellite images are prepared in BMP format for use.
