cOverview of Status of Analysis, Design, Fabrication, Tests, etc.
Design Proposal Presentation on Thursday (4/18)
Parallel approach with IR and ultrasonic (Risk reduction tests being set up and analyzed)
Ordering of parts (Ultrasonic Sensor: Baumer UNDK Series)
Accomplishments from Previous Week
Pig eye experiment ready to go once the set up is ready
CAD for prototype risk reduction testing frame
Research and phone calls with Baumer to get more information on the ultrasonic sensors
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Order an ultrasonic sensor
Keep looking for and working on IR set up and eye safety
Get started on the report (first draft due soon)
Sponsor meeting on Monday (share and update on the sensor status)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Infrared switch experiment: ambient light and other circumstances of concern; intensity variances for each pig eye
Reference frame to make sure that the sensor measurement is correct at all times
Aiming beam: "+" of light beam to help align the center of cornea
Thickness of cornea: 500 microns; width of cornea: 12 mm in diameter
Contour map of profile eye
Average reading: how much accuracy does this allow?
Sensors first and then move onto the magnifier idea (first priority being the automated version)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Comments on the design proposal presentation
Camera idea: why was it shut down?
Good parallel approaches: keep working in separate groups and continue on the search for the perfect sensor
"Okay" on the ordering of $400 Baumer ultrasonic sensor
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Why not take a profile picture of the eye and do image processing?
Risks and Areas of Concern
Budget and the price of ultrasonic sensor
Possible fabrication of the collimator
Resources or Information Required but not Available
Detailed information on the material and physics of collimator
Availability and accurate lead time on Baumer sensors (third party distributors in area?)
