Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

All comments taken from Proof of Concept Presentation on 5/10

• • Need more quantitative analysis:  Completed

  • MB/sec calculation seems to be wrong: Addressed

  • No analysis/justification for not doing synchronization: Addressed

  • Steady hardware progress has been good

  • Address sample frequencies and apply to resolution requirements or do analysis of what you want to learn: Addressed

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

All Comments taken from Proof of Concept Presentation on 5/10

• • Build a rooftop and show highest mu/lambda where lambda is numerical data- Young Woo Soo

  • Filter data to get rid of noise- CJ Cornell

  • Show more of what you have done with coding and use more images with annotations- Tyler Capps

  • Use thicker material or polycarbonate to increase stability of structure- Shawn Mailo

  • Use capacitive sensitivity(???) strips to monitor where the mouse is and think about using noise cancelation foam.  A cardboard box might work to reduce noise- Kevin Chau

  • Use another microphone to help cancel out the noise (subtract signals) and use different colors during presentation- Michael

  • Apply filters to get out noise and incorporate a top cover or sound proof glass.  Also see Mike or Nick about LabView programming- Victor Fung

  • Can LabView distinguish more than 2 sound sources?- Nima Banai

  • 3 brackets, top, middle, and bottom for structural support- Ravr

  • Slides were a little much, hard to read- Jeff H.

  • Will you be able to look into double wall insulation?  Change color of presentation- Adrienne Apacible

  • Is it alright if you resolve ambient noise issues by just ignoring frequencies below ultrasonic- Allan Yu

  • Will mice be distracted by reflectivity of material?  Use sound and light for synchronization- Travis

  • Change slide backgrounds and make text larger- Staphanie

  • Will intrate-wave base sensors help to penetrate the acrylic- Andy Chen

  • Is audio/video necessary?  Use a high pass filter.- ???

Risks and Areas of Concern

• • Incorporation of sensors in both programming and physically

  • Y-maze structure

  • Finalized testing (Run all programs and analysis)

  • Incorporate additional microphones for distinguishing USV's from two different mice

Resources or Information Required but not Available

Schedule

• • Complete Y-Mazes (all 4)- 5/21

  • Incorporate sensors (Programming)- 5/25

  • Incorporate sensors (Hardware)-5/28

  • Order DAQ-

  • Finalized testing- 6/1

  • Possibly order more microphones to distinguish between mice- 6/1

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • • ~300 Ultramic 250K

    • ~30 Sensors

    • ~250 Acrylic

    • Approximately 1850 remains

Progress on Report and Webpage

• • Comments on first draft received and addressed

  • Work on second draft has begun

  • Webpage is updated as project progresses
