2. Introduction Proposed Idea Functional Description Considered Designs Design Constraints Health/Safety Economical/Environmental Manufacturability Sustainability Professional Responsibilities/Ethics Summary References

3. Infrared thermometers have many uses checking mechanical equipment or electrical circuit breaker boxes or outlets for hot spots checking heater or oven temperature calibration and control purposes detecting hot spots / performing diagnostics in electrical circuit board manufacturing checking for hot spots in fire fighting situations monitoring materials in process of heating and cooling research and development or manufacturing quality control situations Redundant to have a separate device

4. Infrared thermometer accessory for smartphones Case equipped with necessary components Same physical principles as a hand-held infrared thermometer lens focuses infrared thermal radiation onto detector converts radiant power to electrical signal signal compensated for ambient temperature, displayed in [F, C, K] using application

5. Planck Radiation Law Stephan-Boltzmann Law derived from Planck's radiation law by integrating over all wavelengths Wien’s Displacement Law

6. Top-level diagram Does not include case; not really a “function”

7. Input Capture and Preprocessing

8. Digital Signal Processing and Temperature Calculation

9. Application

10. Design 1:

11. Design 2:

12. Not a health or safety issue Not a necessity ROHS compliant Environmentally Friendly Manufactured components should come in bulk

13. Should have a UL certification Electrostatic discharge compliant Electromagnetic compatibility compliant Software responsibilities Personal information kept secure Be able to identify possible threats within the program

14. Infrared thermometer has many uses Product is low in cost and easy to manufacture Wide range of consumers Potential to be expanded for other uses Will be compatible with current phones
