Project #1: EMERGENCY VEHICLE ADVANCE WARNING SYSTEM

By: Pao Xiong, Christian Banks, and Rashid Nadeem
Advisor: Dr. J.M. Heneghan
Description: To simplify the operation of the Emergency Warning Systems already in use by police, fire, and other emergency departments. We intend to replace all of the individual components that are wired to mechanical switches in the center console with a laptop computer and a Hub that contains the control for the lighting and siren units. The LED lighting system will be an integral part of the Hub and the siren will be a separate unit because the intentions are to sell the siren as a separate unit as well. The Hub will provide the control lines for already commercially available strobe power supplies and relay modules that provide lightbar control.

Project #2: HIGH RESOLUTION PIN-MATRIX COMPUTER DISPLAY FOR THE BLIND AND VISUALLY IMPAIRED

By: Lloyd Dalton, Sultan Faiz, and Rabindra Sainju
Advisor: Dr. A. Narayana
Description: To design and prototype a high-resolution pin-matrix computer display. The display will use very small actuator pins in place of pixels to duplicate the output of a section of a black-and-white computer monitor. Information presented in this way will then be accessible to blind and visually impaired persons.

Project #3: MOBILE, PROGRAMMABLE, AUTONOMOUS ROBOT

By: Riazul Islam and Yap Yong Ng
Advisor: Dr. B. Carruth
Description: Our goal was to design and develop a mobile, programmable, and autonomous robot using MC68HC11 microcontroller which provides 256 bytes of RAM and 2KB of EEPROM. This mobile robot displays intelligent behavior and responds to certain external stimuli. Robot is able to detect a bright light source and designed to follow the source. It is also designed to avoid obstacles it may encounter. It generates signals as it detects light source or encounters any obstacles. The signal then would be transmitted using a broadcasting system and thus enable us to hear its activity form a remote place using an ordinary radio.

Project #4: SINGLE LINE MULTI-USER TELEPHONE SYSTEM

By: Michael Hansen, Kristin Lindholm, and Aaron Weyer
Advisor: Dr. B.W. Ellis
Description: To alleviate phone troubles in a house with multiple extensions. This system has an automated call directory that allows a caller to select an extension. After an extension is entered, the system will ring that extension eliminating the need to search for the call recipient. The integral parts to the project are the main module on the incoming phone line and the remote modules at each telephone. Some of the typical applications for this system are small businesses, single family dwellings, and student housing.

Project #5: VOICE RECOGNITION CALCULATOR

By: Ryan Przybilla, Jeremy Leitzen, and Yong Chee Wai
Advisor: Dr. P. George
Description: Our goal is to build a voice recognition calculator. This calculator will be able to do some simple mathematical operations such as multiply, divide, add, and subtract. The numbers and operations will be entered either manually or by speaking into the calculator. The answers will be displayed on a LCD and spoken using a voice synthesizer. This calculator could be very useful for handicapped people or for people who are busy with their hands.

Project #6: WATER TREATMENT SYSTEM ALARM DIALER

By: Kraig LaFreniere, Joel Anderson, and Bijoy Anose
Advisor: Dr. S. Lekhakul
Description: The objective of this project is to construct a water treatment system alarm dialer for Total Control Systems, Inc. (TCS). TCS designs and constructs the control systems for water treatment facilities. Our goal is to construct a device to monitor the status of signals generated by a Programmable Logic Controller (PLC). Signals generated will be connected to the inputs of the dialer. When an error is detected, the unit will notify a specified individual with a prerecorded telephone message(s). The unit will continue to notify that an error has occurred until the error is acknowledged with a keypad sequence input by a telephone. The device will be capable of contacting a user-defined list of eight individuals that an error is active. It will continue the cycle of calling the numbers individually, until the problem has been acknowledged.

Project #7: WIRELESS AUDIO DIGITAL COMMUNICATION SYSTEM USING CDMA SPREAD SPECTRUM TECHNOLOGY

By: Rahim Allana, Keehoon Chan, and Jonathan Tang
Advisor: Dr. P. George
Description: The objective of this project is to learn and apply knowledge concerning digital communication systems; more specifically, CDMA spread spectrum technology and digital signal processing (DSP) concepts; in the process of constructing a digital audio communications system.
