  • Red B
  • Safety Security
  • October 2, 2008

2
The Tent
  • Rigid structure collapses into a small package
  • Carrying size (3x8x2)
  • Becomes full size sturdy tent (6x6x5)
  • Lockable
  • Collapsible
  • Durable

3
Emergency Shelter Market
  • Hurricane Katrina

The Idea and Motivation
  • A system which shuts off a microwave if sparks
    are detected
  • Microwaves caused 7,400 fires in 2005
  • 87 injuries and 18 million property damage.

Customer and Market
  • Customer Original Equipment Manufacturer
  • Major microwave producers
  • GE and Sharp have gt40 market share
  • End-User households
  • 13.5 million microwaves sold last year in US
  • 3.8 billion sales

9
Can We Detect Sparking?
  • Light intensity
  • Sound
  • IR
  • Magnetron power draw
  • RF emission

Future Work
  • Try other sensing methods
  • Establish detection thresholds
  • Test for false positives
  • Design of sensing and control circuitry
