The Bicycle computer's main purpose is to provide the
rider with power information. Due to the number of
inputs used to achieve an accurate power number
other information a cyclist might be interested in will
be provided. Such as:
Rate of Acension
% Grade
Speed
Pedaling Cadence
Torque
Temperature
Wind speed (component parallel w/rider only)
Altitude
Heart rate
Distance since Reset
Time Since Reset
Vertical Ascension Since Reset
These parameters will be available using handlebar
mounted buttons to scroll through and select
parameters to display.
Altitude/Baro
Sensor
Totals will be resetable w/buttons
Display
Power Supply
Rider enters parameters such as:
Frontal Area
Riding Weight (Including bike, water, etc)
Type of Wheel (Aero,all purpose,conventional)
Rotational Inertia of Wheels?
Rolling Diameter of Wheel/Tire
Starting Altitude
Auto Green House
The purpose of this project is to make an all in one controller
for a green house. In the block diagram there are nine blocks.
Power Supply: Supplies power to every other block, except
the wireless output.
Input: User interface, user will be asked to set system
requirements.
Lights: Controls amount of light exposure.
Humidity: Controls humidity and watering in the green house.
Temperature: Controls temperature regulating and air flow,
looking for
consistency throughout the green house.
Wireless Transmitter/Receiver: Sends and receives output
information to wireless output device.
Power Supply 2: Powers the output device.
Output: Outputs current readings in the green house.
Pulse Oximeter and Respiratory
Monitor for Laboratory Rats
-Detection of blood
oxygen level using
absorption levels of
LED wavelengths.
-Monitoring Heart Rate
and Respiratory level
Selection Matrix
Recommended Project
-An Instrument To display Blood Oxygen
Content, Heart Rate and Respiration Rate of
a Laboratory Rat using oximetry.
-The monitor should be able to display a
reasonable range for a typical rat pulse and
percentage of oxygen level.
-There are no currently known similar products
on the market for the use on research rats.
