Automatic Water Detection/Shutoff
• Water damage due to leaking hot water heaters or faulty plumbing
can be devastating to a homeowner.
• Electronic detection of water is a fairly simple task – products
that sound an alarm when water touches a sensor are
commercially available.
• There is a need to incorporate an automatic shutoff valve to the
main water feed when the presence of water is detected.
• In order to reduce the hazards associated with electric sources in a
humid environment, such a system should operate on battery
alone.

Secure Mailbox Project
Goal:
Design a mailbox that can be accessed only by a code when full of mail,
and yet available for opening by the mail carrier when the mailbox is
empty.
Operation:
1. Mail carrier puts mail in the box, then lifts up the flag. The flag is
attached to a lever that sets a lock as it is raised.
2. Later in the day, the resident comes to pick up mail. He / she enters a
code on a keypad which disengages the lock. He / she opens the door,
gets the mail, pulls down the flag and closes the door. Door to the
mailbox is now free to open.

optical fiber to transmit a message.
• A team project with three main parts: Baseband,
Modulation, Demodulation

User Interface for Human Tremer Software
A test bed for generating artificial
human tremers and saving the electrical
signals of motion to Excel has been
built and tested.
A mathematical program has also been
developed to analyze the tremers.
There is a need for the development of user-interface software to
allow the user to test various types of analysis with different
types of tremer signals.

Ultra Wideband (UWB) Communications
UWB is a system that has promise for high data rate
wireless communications within a short range.
The current UWB system in the E&T department needs to
be thoroughly tested.
Test equipment in the E&T department can captured realtime pulses from the UWB system and can analyze
spectral energy up to 70 GHz .

Ultra Wideband (UWB) Communications
The student working on this project will:
• Learn how to use the UWB system,
• Learn how to use the test equipment.
• Thoroughly test the UWB equipment in different wireless
environments.
• Report on the test results paying attention to the capabilities
and susceptibilities of the UWB system.
• Write a computer program to simulate the UWB system in a
noisy wireless environment and compare the simulation results
with measurements.

Web-Based Simulator for Student Interactive Laboratory
Activities
Background:
Equipment for laboratory activities is often very expensive and not
available to most institutions. Example: Medical Imaging equipment
for experiments by engineering and science students.
Digital technology simulators can be developed and used for effective
training. Example: Aircraft simulation for pilot training.
Open-source web-based simulators allow students anywhere in the world to
perform a variety of interactive learning activities.

Web-Based Simulator for Student Interactive Laboratory
Activities
Phase 1: Research of Simulation Methods
Result: report on the current and equipment simulation methods and
applications.
Phase 2: Design and development of a simulator.
A particular instrument or type of equipment will be selected and a an opensource web-based simulator to enhance engineering education will be
developed.
Phase 3: Evaluation
The simulator will be evaluated by selected students and faculty in several
institutions.

Mathematical Modeling of Human Motion
Background:
3D computer models of the adult human body are
available for biomedical researchers. These
models are typically positioned in the upright
position. There is a need to have available other
positions such as sitting down, reaching up with
the arm, etc. The different positions allow
researchers to test the electrical effects on the
human body in different positions.

Mathematical Modeling of Human Motion
Background (continued):
Models of children are not always readily available. However there is a need
to mathematically model electrosurgery on children because they are
susceptible to harmful heating effects of these instruments. Children have
a head that is proportionally larger than that of the human adult and arms
and legs that are wider than the average adult. Adult models can be rescaled to approximate that of a child.

Mathematical Modeling of Human Motion
Requirements:
1) Write a computer program to re-position the limbs and
torso of a 3D computer model of the human body. The
program should be able to bend the arms at the shoulder
and at the elbow. The program should be able to bend the
legs at the hip and at the knee.
2) Write a computer program to rescale the adult model to
the dimensions of a young child.
