2. Team 6 Reintroduction Ben Moes Andy Gabler David van Geest Nathan Brinks

3. Outline • Project Reintroduction • Design Norms • Wireless Decision • Progress • Challenges • Lessons Learned • Questions

4. Project Reintroduction • An electronic stethoscope that will: • Aid in auscultation • Record digital audio data from the patient • Perform frequency filtering • Store the audio files on the device • Transfer the audio files to a computer via USB • Contain these features in a convenient media-player like form-factor

5. Design Norms • Transparency: must be easy to use, no technical experience required • Stewardship: must protect the user, patient, and environment. HIPAA, Latex Free, RoHS • Integrity: must provide an accurate representation of the sounds produced by the body

6. Wireless Decision • Pros of Wireless: • No Wires! • Simpler for User • Professional • Cons of Wireless: • Separate Power Supply • Fidelity • Cost

7. Wireless Decision • Considerations • Wireless Options • Range • Reliability • Not too much more work • Development Time

8. Wireless Decision • Choice: F2M03MLA: • Benefits: • Made for Streaming 16bit Audio • Small Efficient Package • Full FCC Qualification • Built in Firmware • Deterrents: • Cost
