Balance Relay Replacement

By: Muhammad Atique, Eric Augustine, and Bryan Berg
Advisor: Dr. J. M. Heneghan

The objective of this project is to replace the balance circuit relay board of the S984, manufactured by Honeywell, Inc. Currently, the balance relay is an electro-mechanical device. The S984 is a device that is used to control the heating or cooling of mainly larger buildings by adding or subtracting heating or cooling coils with the use of micro-switches. Our intention is to develop a few different electrical designs to replace the existing one. This new design will operate under the extreme environmental conditions and possible surge voltages. Honeywell has agreed to finance and to provide technical support for this project.

Caller Identification Device

By: Salva Raja Andiappan, Alan Seah, and Yan Chi Chan
Advisor: Dr. A. Narayana

The Caller Identification Device receives and displays information about the calling party from participating central office facilities of the public switched network.

Digital Audio Effect Processor

By: Raymond Wong and Dean Burdick
Advisor: Dr. A. Narayana

The objective of this project was to create audio effects using real-time digital signal processing. A digital audio effect processor was designed and implemented using an IBM compatible PC. The analog audio signal will be input to the PC via an ISA interface card, which was designed by us. The card will convert the analog signal to a digital signal, which is then processed by the PC using various digital-filtering techniques.

Doppler Color Flow Imaging Subsystem for a Medical Ultrasound B-Scanner

By: Chris Bruflodt, Mike Fette, and Arne Niska
Advisor: Dr. Y. Zheng

The project objective is to design a Doppler color flow imaging subsystem for a medical ultrasound B-scanner. The inputs of the system are Radio Frequency (RF) Signals from a beamformer of a B-scanner, and control signals from a Digital Scan Converter (DSC).

EPLD Programmer

By: Chris Groves and Mohammad Farooqi
Advisor: Dr. B.W. Ellis

The EPLD Programmer will serve as an alternative to the IO 3900 for programming GAL 16V8A and 16V8B.

H20 Temperature/Flow Controller

By: Chad Chryst, Sara Polucha, and Corey Swenson
Advisor: Dr. S. Lekhakul

The project involves designing and building a working prototype of a water temperature and flow rate controller. The unit will be able to connect to any faucet, such as showers, sinks, and outside faucets. The user will be able to input a temperature and flow rate of the water and adjust the hot and cold water valves when needed.

Message Management Unit (MMU)

By: Kevin Bayer, Asif Siddiqi, and Steve Miller
Advisor: Dr. J. Rankin

The objective of this project is to design an Air Traffic Control (ATC) Message Management Unit which will provide a front-end tool for research in ATC Two-Way Data Link Communication. This MMU will send instructions to the pilot digitally over a RF frequency. The proposed MMU will send information to the pilots in such a way that they will only be aware of their own individual instructions.

Real Time Measurement of the Electrical Parameters and Calculation of the Energy Characteristics of an Arc

By: Robert Craig and John Pagels
Advisor: Dr. J. Rankin

The scope of this project is to measure and quantify the electrical and energy characteristics of an electrical arc. Another aspect of the project is to design and build an AC phase controller. The AC phase controller will give the user the ability to initiate an electrical arc at any point on a half cycle of the 60 Cycle line voltage signal.

RF Correctional Data Interface (RF CDI)

By: Dave Bremer and Brian Schaefer
Advisor: Dr. J. M. Heneghan

The project objective is to design a hand-held interface that utilizes correctional data broadcast on an FM frequency to improve the accuracy of a portable Global Positioning System (GPS) receiver.

Serial CCD Interface Manual

By: Tony Dunker, Alan Hewitt, and Robert Roy
Advisor: Dr. J. M. Heneghan

The modifications in the design of the Serial CCD Telescope System were intended to make the CCD Telescope System a remote system whereby the user could fully control the telescope from distances of 100-200 feet away. The CCD Telescope System consists of a CCD Camera, Pre-amplifier Card, Interface Box, the User Interface Program and the Motor Control Box. The CCD Camera and Pre-amplifier Card are mounted together and connect to the telescope. The Interface Box connects the Pre-amplifier Card to the User Interface Program.

Talking Mobile Robot

By: Lee Kantor, John Kylander, and Curt Lieser
Advisor: Dr. S. Lekhakul

The radio controlled talking mobile robot features a speed control, a proximity sensor, a light sensor for operating in darkness, a voice chip for recording and playing back messages and two low voltage sensors for the individual battery packs. The first mode is user controlled and the other is a stand-alone mode, which is controlled by the microcontroller. In user controlled mode, the operator has complete control of the robot. In stand-alone mode, the robot operates with the use of onboard sensors combined with a microcontroller.
