Power Supply Project
Minimum Specifications

• Two variable output voltages
• 0 to 12 volts 0 to -12 volts
• Both outputs capable of delivering up to 500 mA.
• Digital readouts of output voltage and current.
  A single digital readout with a switch for output
  current or voltage is acceptable.
• Digital readout(s) will be accurate to within
  0.1 volts, 1mA.
• Short circuit protection on both outputs.
• Both outputs will be regulated. No worse than 1
  variation in output voltage between no-load and
  full-load.
• AC line insulated from case and fused.
• Clean circuit board layout.
• Professional appearing enclosure. No hanging
  wires.
• Write a complete maintenance manual with trouble
  shooting guide.

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.
6
Optical Communications System

• Goal
• Design a digital communication system which uses
  an optical fiber to transmit a message.
• A team project with three main parts Baseband,
  Modulation, Demodulation

7
Optical Communications System

• Baseband Specifications
• Analog source (Function generator, audio, or
  voice)
• Analog-to-Digital Converter
• Parallel-to-Serial Conversion
• Serial-to-Parallel Conversion
• Digital-to-Analog Conversion

8
Optical Communications System

• Modulator
• Baseband, PSK, or FSK optical modulation
• Demodulator
• Baseband, PSK, or FSK optical demodulation
• Channel
• Optical fiber

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.
10
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 ET
department needs to be thoroughly tested. Test
equipment in the ET department can captured
real-time pulses from the UWB system and can
analyze spectral energy up to 70 GHz .
11
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.
13
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 open-source 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.
14
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.
15
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 re-scaled to approximate that of a child.
16
Mathematical Modeling of Human Motion

• Requirements
• 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.
• Write a computer program to rescale the adult
  model to the dimensions of a young child.
