1. Project Head Case ( Eye Pattern Detection) Designed by Group H Dan Klowden, Jon Burns Presented by Rebekah Henkel, Anita Phillips, and Anh Ton

2. TOP SCHEMATIC

3. Eye_SIG Contains: EYEFRM SIG_CTRL

4. EYEFRM Functional: determines whether or not the eye is closed.

5. SIG_CTRL Functional: determines if the eye has been closed for 2 sec. Includes 5 states: Counting, EyeCWait, DoneCnt, ACKwait, and FRMwait EYECLOSED

6. SIG_CTRL (Cont.) Counting Compare With CALIB and Return EyeCWait DoneCnt ACKwait FRMwait CameraFrame Asserted and Count < 40 Less Than 38 / 40 EyeClosed Signals Asserted CameraFrame Asserted CameraFrames = 40 ACK Signal From 8051 CameraFrame Asserted ACK Signal From 8051 & CameraFrame Not Asserted At least 38 / 40 EyeClosed Signals Asserted

7. Suggestion - Add extra pins to choose which control states to switch to. (cyclic order for now) | | | time 2sec - After eye is closed for 2 sec, require that the eye to open before starting counting again.
