  2. Microwave Metal Detector

  3. 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.

  4. Customer and Market • Customer: Original Equipment Manufacturer • Major microwave producers • GE and Sharp have >40% market share • End-User: households • 13.5 million microwaves sold last year in US • $3.8 billion sales

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

  6. Light Intensity

  7. Sound No Spark Sparking

  8. False Positives?

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

  10. Questions, Clarifications, Concerns?
