156B Week 9

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Analyzed three seperate recording of 8 day old mice, 12 day old mice, and two male mice together. Result: No vocalizations, only background noise.

  • Revised the Motion sensors VI in order to count and timestamp the entering and leaving of mice for each tunnel on the y-maze.

  • Want to test sensors before the end of the week.

Accomplishments from Previous Week

• • Completed the fabrication of y-maze.

  • Analyzed the recording of mother mouse and pup

  • Completed the motion sensor VI.

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Analyze the recording from the microphone from outside and underneath the y-maze using ultrasonic signal emitted from headphone.(Sam/Sonya)

• Testing motion sensing LabView VI with the sensors (Sam/Phong)

• Physical integration and mounting of sensors to mazes (Caren/Sonya)

• Wiring of sensors to DAQ cards (Sam/Phong)

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 from Week 8 presentation

• • Good progress in: getting data from mice, identifying source of noise, and investigation of frequency response

  • Presentation lacked quantitative data in numerous places: Addressed

  • Y-maze and sensor presentation were not organized clearly: Addressed

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

All comments from Week 8 presentation

• • Build a rooftop casing for sound proofing: Young Woo Sao

  • Nice presentation.  Use filters: Ravi

  • Discussion of freq. was hard to follow: Jeff Head

  • Why are you using black acrylic: Ebrahim K.

  • Wirelessly transfer data? Consider using slots instead of puzzle pieces: Victor Fung

  • Hard to follow discussion. Good overall presentation: Tyler Capps

  • Project has progressed well: Pegah Khorsandian

  • Test clear were well done.  Try using a better mic: Oscar Pias

  • Why do you car if the lens is big enough? Try to emphasize how you would solve the problem: Andy Chen

  • Try filtering out the noise.  Good in depth testing: Nima Banai

  • Do you need to write operating procedures?: Adrienne Apacible

  • Try to be clear on the units and what they mean: Patrick Charles

  • Spend more time facing the audience: Marwan

  • Good presentation: Travis Weightman

  • Good job: Jonathan R.

  • Condense conclusion.  Presentation too long: Cary Choi

  • Use filter.  Consider maze height: Luis

  • Well done: Leonardo Costello

  • Handles can be made into swivels: Kyle Stewart

  • Good presentation: Sean Patno

  • Nice testing: Reginald Ballesteros

  • Watch your time: Hien Nguyen

  • Nice work: Shawn Mailo

  • How will you account for range of sensitivity: Ethan Archibald

  • Nice LabView: Nathan Leamy

  • Still seems like a lot of unknowns: Frank Buchanan

  • Goo overview of components: Allen Yu

  • Good analysis of microphone sensitivity: Daniel Healy

  • What part does motion sensor play: Jana Dadhaniya

  • Explore some things to far into detail: Emmanuel Pun

  • Good job: Kevin Chau

  • Were there other options that acrylic: Thomas Tran

Risks and Areas of Concern

• Non-uniform microphone frequency response

• Ability to detect mouse signals from farthest points in the maze

• Ability of IR sensors to function through 0.25 inch acrylic

• Having enough time to integrate sensors once they are received

  • There is a possibility of error using headphone as ultrasonic emitter since the headphone can caused the inconsistencies and exaggerated reduction in response for upper frequencies.

Resources or Information Required but not Available

• • The IR transmitters and phototransistors has yet to arrive.

Schedule

• Test sensors through 0.25” acrylic – 6/1

• Incorporate sensors (Hardware)- 6/1

• Finalized testing- 6/2

• Present a draft presentation to sponsor - 6/4

• Final sponsor presentation - Final week

Budget (list amount spent and amount remaining)

• ~300 Ultramic 250K

• ~24 Sensors

• ~250 Acrylic

• Approximately 1850 remains

Progress on Report and Webpage

• • Each team member’s assigned portion of the report is complete, but all parts must be integrated and properly formatted

• Updated the website including an executive summary.
