Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Ultrasonic sensor received on Monday
Beginning of initial testing with the new sensor (Range, slope, calibration, etc.)
Sponsor meeting on Wednesday @ 6pm
Accomplishments from Previous Week
More research being conducted about 3D scanners (Using a laser to determine distance or possibly the contour shape)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Calibration of ultrasonicÂ
More research on IR and deciding on an order
Begin the framework and determine the placement of encoder once the parts arrive
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Test results from ultrasonic (graphs)
Arrangement of final design - vertical / horizontal?
Too many degrees of freedom?
Power requirement
IR concern: looking away while application might cause direct contact with the light (burning sensation?)
Encoder updates
10 - 35 mm of range for bulging of eyes
Framework: reference point, orbital or front
Next week: prototype, LCD screen, bring in the current device
Wednesday 5pm
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
3D Scanner
Reflection of IR (Critical angle calculation)
Array of IR (Combination which can allow calibration and microprocessor)
Receiver must be for the correct IR range
Del Mar Seminar for 3D scanner (Possible field trip for research purposes)
Make a decision of sensor by next week
NEXT WEEK: Review of IR; overview of 3D scanning technology
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
N/A
Risks and Areas of Concern
Unsure of IR option
Ultrasonic calibration for curved eye surface with eyelids
Sensing range of ultrasonic
Resources or Information Required but not Available
3D scanner technology
Schedule
CAD done for testing bed of ultrasonic on curved surface
More data to finalize calibration
Finish final design and establish a 3D model of it
Budget (list amount spent and amount remaining)
Purchases: Ultrasonic sensor & encoder
Progress on Report and Webpage
First draft of report by Friday
Webpage front page finalized
