1. Knee Brace with Feedback Honey Bunnies: Craig “I broke the prototype” Greiner, Rich “Stoner” Stoner, Jason “Mr. Benedum” Woods Mentor: Dr. George “Big G Stet” Stetten Presented by Zack “Jerkface” Mason Senior Design Update March 29th, 2005

2. Senior Design Update Knee Brace with Feedback Project Description Problem: Vague interpretation of flexion angle in knee after surgical procedure and during rehabilitation Solution: Portable digital goniometer, integrated into a soft brace with a digital output

3. Senior Design Update Knee Brace with Feedback Current Design

4. Senior Design Update Knee Brace with Feedback Project Status Initial prototype design completed 3D model of knee acquired Parts received Breadboard circuit constructed and in general working order Redesign underway

5. Senior Design Update Knee Brace with Feedback Upcoming Problems Redesign of prototype Battery and circuit packaging

6. Senior Design Update Knee Brace with Feedback Personal Focus – Electronic Components Locate appropriate components (microprocessor, LCD screen, BCD to 7 Segment Decoder, etc) Program microprocessor Test circuit Get circuit into functional form for the kneebrace

7. Senior Design Update Knee Brace with Feedback Personal Achievements Circuit constructed Programmed and tested microprocessor with PIC16C765 (actual device will use 745) using MPASM with MPLAB IDE v7.1 Program in general working order (still a few bugs, but it basically does what we want it to)

8. Senior Design Update Knee Brace with Feedback Acknowledgements Mark “Deliverables” Gartner Dr. Stetten (best professor EVER) David Weiser Group Members

9. Senior Design Update Knee Brace with Feedback Work-To-Do Get circuit working fully and integrate into new prototype Conduct testing to adjudicate success - accurate to 1 degree - 3 digits (?) - comfortable to wear/easy to use

10. Senior Design Update Knee Brace with Feedback Questions Where do babies come from? Will Episode III be good? What is the appeal of reality TV? Bush is president AGAIN?!
