Cyclist Power Meter

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.

Block Diagram Description Block Name Owner Brief Description Of Block Function Power Interfaces Digital Analog 1 Power Supply Michael Kozich Converts Commercial AC Power to +/-5VDC and +/-12VDC with battery backup battery for 2 hours. In: AC Out: 5VDC, +/-12VDC None Out: Vbat 2 Microcontroller Robert Barrows Will Communicate with a/d, Safety circuit and Display/Control circuit. Also will carry out equations for determining Blood Oxygen Ratio. In: 5VDC Out: Data Bus, In: Anolog inputs, I/O In: Vbat 3 Display/Control Brian Provides user inputs for sampling speed, calibration, display, and feature control. In: 5VDC, +12VDC In: Data Bus Out: I/O on micro 4 Safety Circuit Naser Monitors voltage levels of the different blocks and communicates with power supply. In: voltages from all blocks 5 Respiration/ Heart Abdul Takes the analog signal from the heart rate monitor and respiratory circuit and increment digital words with each beat/breath In: +/-12VDC Out: two digital words to micro I/O In: Respiratory signal, heart beat signal 6 LED Driver Circuit Ahmad Generates pulsing light signal that propagates through rat tail Out: square waves to drive LED 7 Signal Conditioning Dave Takes light pulses detected by sensors and converts them into normalized analog voltages. In: square waves from light sensor Out: Two voltages and an ac signal
