  1. Sensor on glasses Part A Final & Status Presentation Performed by: Danielle Perez ShukiEizner Instructor: Alexander Kinko Duration: 2 Semesters

  2. Table Of Contents • Short reminder -project’s goals. • project design. • Project activities and status . • Analogues PCB. • Digital PCB. • Next assignments. • Gantt chart.

  3. Project’s Basic Concept Patient Doctor Eyelid Movement Sensor Device (EMSD) PC Application (Doctor’s workspace) Results of analysis

  4. Project’s Goals Develop a portable, low-power system that will check the eyelid movements and analyzed the results. The system has the following features: • Portable system • Enables better tracking of the blinks by storing data, describing specific eyelid movement which include: • Starting and ending time (10-15 minutes each test) • Velocity • Frequency • Position • Have the ability to analyze each eye separately.

  5. Project’s Goals – continue • Designing PCB, resulting in a small low-power eyelid movement sensor device (EMSD), which going to be placed on the glasses. • Powered by rechargeable battery, that is recharged by connection to the external power source. Low battery indicator alerts user when the battery is low.

  6. Project design

  7. Analogue PCB- activities and status • Preliminary design and characterization. • Found necessary HW for all features. • Electrical design. • Routing. • production. • Primary debug.

  12. Digital PCB- activities and status • Preliminary design and characterization. • Found necessary HW for all features. • Electrical design for all possible hardware. • Routing. • Production.

  13. schematics

  14. Routing Layer1-TOP Layer2-VDD Layer4-Bottom Layer3-GND

  15. Next assignments • HW debug which include the following tests: • LEDs – simple check that the LEDs are working, Check the intensity (in case of problems: • HW solution- Change the resistor value. • SW solution- PWM mechanism.) • Switches - simple check of controlling on other components by using the buttons. • Buzzer- check the buzzer by producing a voltage at 4kHz (needed: PWM mechanism)

  16. Next assignments-cont’ • Crystals- check the correctness of the frequencies, the frequencies can be viewed using the scope. • EEPROM- write/read operation. (needed: relevant protocols, data organization) • Micro-SD- understanding and implementing the relevant protocol. write/read operation. (needed: relevant protocols, data organization) • USB- check the connectivity.

  17. Next assignments-cont’ • Power module- LDO- checking the turning on/off mechanism DC2DC- check the conversion to 5V. (ENA=‘1’ => PG=‘1’) power manager- stat lines, the LEDs can reflect the battery stat, PM_BAT_STAT. (needed: A/D mechanism) • Connector- simple check with the scope to the analog waves, final check in the GUI interface. (needed: A/D mechanism, GUI interface)

  18. Gantt Chart
