SAM Unit Redesign and Integration
Project SAMURAI:
A Silent Killer
CO2 concentration increases due to: Poorly ventilated areas Combustion of fossil fuels Human respiration
Exposure to elevated levels can lead to hypercapnia, resulting in possible death
3
CO2 (ppm)
Warning Level
Side Effects
300-400 None None
10,000 Low Slight drowsiness, headache
20,000 Medium Chest heaviness, more frequent and deeper respirations
30,000 High Breathing rate doubles, heart rate increases, risk acidosis
50,000 Critical Sensory dysfunction, unconsciousness, death

Background
SAM filters can detect various gases including CO2 and refrigerants
Detects leaks sooner and at lower levels to avoid air quality fines Section 609 of EPA’s Clean Air Act
allows for fines of $32,500 per day!
OSHA Indoor Air Quality Standards
Wide range of industrial and commercial applications

Project Objectives
Fully integrate Windows CE environment
Develop remote configuration application
Create peripheral interface board
Develop standalone remote monitor with LCD
Design power inverter for pump

SAMURAI: SAM Unit Redesign and Integration
Justification
Final product has the potential to save lives
Opportunity to give new face to product line
Installation cost is currently too high for some customers
Reduce operating costs by eliminating avoidable fines 6
