2. Project Proposal #1: IR Sensor System for Aquatic Neurobehavioral Research
Power Supply, IR Transmitter, IR Receiver, Filter, Feeder System, Microprocessor, RS232 Port
Project is designed to test the effects of positive reinforcement in a controlled habitat for fish. Upon the visual stimulus of a green light, the fish will be prompted to cross the infra-red barrier releasing the food at the opposing end of the tank.
Advantages of Project for Team #4:
Previous research and experience in optics
Prior microprocessor design and buildup
Knowledge of control devices

4. Project Proposal #2: Thermal Controlled Automated Blinds
Project is designed to control the operation of window blinds based on a circuit’s response to the strength of the light outdoors and the temperature. Blinds will open and close automatically in an attempt to conserve and control energy consumption.
Project should utilize an AC power supply, photocell circuit, temperature sensor, comparator, logic, stepper motor
Advantages of Project for Team #4:
Previous experience and interest in logic
Previous experience in temperature sensor design
AC/DC Motors and Control experience

8. Selection Matrix – Average team scores 0-100

9. Project Selection Overall Selection Process Project Advantages:
Provides an opportunity to design a product based on customer requirements
Project will be funded up to $1000
Design will utilize strengths of team
Project will be original and free from competitive market
Project Risks:
Potential for design conflict of interest
Working prototype must be within tolerances and design specification as it will be implemented in customer’s research

10. Project Selection Overall Selection Process Rejection Process
Previous projects proposed did not support the necessary amount of blocks required
Projects rejected did not offer the challenge or complexity for senior design
Initial ideas had been previously attempted by senior design groups at other colleges
Team Decision
Team completed the selection matrix and chose to move forward with the design of the Fish Tank Apparatus
Team unanimously agreed on the selection of the final design

11. Proposed Product: IR Sensor System for Aquatic Neurobehavioral Research
This product is designed to assist in the research of neurobehavioral studies of fish, through the use of positive reinforcement
Project will be used to collect data for study at the Great Lakes Institute
System will serve as a training device that will record data used to identify neurobehavioral activity of fish
The project will be the first attempt to collect data for aquatic neurobehavioral studies
No known products are currently on the
market
This product is developed for use in
water and marine research
