Project #1: AUTO FLOW SENSOR FOR NSP

By: Jim Harklau, Tiang Thien Chan, and Sonny Vembaiyan
Advisor: Dr. J.M. Heneghan
Description: A portable flow rate device was designed and built. It is designed to use the output signal from the velocity sensor and automatically calculate the flow rate.

Project #2: LIME PROJECT

By: LaMonte Koop and Muhie Chaaban
Advisor: Dr. S. Lekhakul
Description: This was designed to enhance firmware ROM development. The LiME was developed as our senior design project during this academic year. It consists of a hardware PROM emulator and menu driven interface software for ease of use.

Project #3: PORTABLE HEART MONITOR*

By: Kol Johnson and David Simonson
Advisor: Dr. Y. Zheng
Description: The project simulates a typical research and development cycle for a bio-medical instrument. The scope of the project includes the definition of product features, design of circuits, specification of components, research of applicable safety standards, along with the construction and evaluation of prototypes.

Project #4: POWER MONITORING SYSTEM**

By: Edmond Wong, Faisal Khwaja, and Larry Fries
Advisor: Dr. J. Rankin
Description: The project objective is to design and implement a power monitoring system using the TENMA AC clamp adapter. By clamping the adapter around any single power lead (i.e., of an appliance) the system can periodically sample load current and store data in RAM. This data can then be downloaded to a PC via an RS 232 cable. A graphical display of power consumption vs. time can then be generated. Also, the system can provide an instantaneous current reading via LCD display.

Project #5: SECURITY SYSTEM COMMAND CENTER

By: Todd Reiter and Ho Yee-Seng
Advisor: Dr. S. Lekhakul
Description: The Security System Command Center was a design mission to create a stand-alone security-monitoring device. This stand-alone security monitoring device was to monitor 4 distinctly different zones, allow user programmability (i.e. phone numbers and voice messages), operate under extreme conditions (battery backup, phone line surge protection), and exhibit low power consumption. Above all, it was to remain relatively inexpensive thereby allowing the average homeowner the option of flexible home security without flexing the limits of their finances. The Security System Command Center's design configuration and specifications are supplied throughout the expanse of this report.

Project #6: STAND ALONE CASH REGISTER (SACR)

By: Corey Larson, Edward O'Donnell, and Scott Weis
Advisor: Dr. A. Narayana
Description: The SACR is designed to offer small and/or new businesses with an inexpensive way to keep track of their receipts, perform normal operations, have multiple registers communicating with each other, and to compile reports without the need of a costly computer. During the design process as a whole, great care has been taken to design not only an inexpensive product, but also to make it user-friendly so that it doesn't take a rocket scientist to run the register. The register will be menu driven so that all the register operator will have to do is enter the information that the register prompts, and the register will do the rest.

Project #7: 20 MSPS DIGITAL SPECTRUM ANALYZER

By: Mike Morgan and Shawn Wiltz
Advisor: Dr. Yi Zheng
Description: Design and implementation of hardware, software, and drivers necessary for 20 Msps digital spectrum analyzer with display on an oscilloscope or personal computer using a Texas Instruments TMS320C25 Digital Signal Processor (DSP), 85C30 serial communications controller (SCC), LCD screen, 20 million sample per second (20 Msps) analog to digital converter (ADC). Control of spectrum analyzer achieved through PC or keypad/LCD interface in stand alone mode.  Power spectral density obtained via real valued Fast Fourier Transform (FFT) computed on DSP.  Display on computer using aplication specific object oriented SVGA graphics driver.  Display on digital oscilloscope via Digital to Analog Converter (DAC).
