  1. Parkinson’s patient & doctor aiding system Progress & Status Presentation Performed by: Alexander Kinko Stanislav Shapiro Barukh Trabelsi Shahaf Yaron Ezra Ehud Vardi Instructor: Boaz Mizrachi

  2. Project’s Basic Concept USER  PC Interface Parkinson’s Patient PMD  PC Interface PMD – Parkinson Mobile Device (*) PC (*) - There are 2 versions of PMD developed: minimal/basic (small box) & enhanced (big box).

  3. Agenda • Functional description of the system • Description of performed project’s activities until now • Description of future project’s activities • Budget & Costs

  4. Functional Description Of The System • Recognition of a unique nature of Parkinson’s tremor (2÷10 Hz). • Recognition of maximum 2 Parkinson’s attacks per minute. • Storing parameters (starting time, duration, strength, frequency) describing each Parkinson’s attack in the non-volatile on-device memory. • Optional notification to patient on appearing of Parkinson’s attack by: • Buzzer / LED indication • Vibration (enhanced system only) • Interconnection to PC for performing extended data processing and better tracking.

  5. System’s Features • Autonomous portable system, that can be worn on the Parkinson’s patient wrist. There’s an option, to put it on other patient’s organs as well (head, leg, etc.). • Both systems (minimal and enhanced) are small: minimal system – 15x32x52mm, enhanced system – 18x43x68mm. • Minimal period for storing parameters - 7 days. • Power supply by 3 different sources: solar cell, rechargeable battery and USB. “Low-battery” state alert. • Communication with host PC by 2 different ways: IrDA & USB.

  8. Performed Project’s Activities Until Now • Preliminary design and characterization of the system Hardware: • Found necessary hardware parts and devices for all features • Complete electrical design for both systems (minimal/basic and enhanced) • Detailed mechanical design with 3D model, ensuring all hardware parts can fit, for: • Small box • Big box • Layout and production for both systems (in progress) Software: • Basic programming modules

  9. Electrical Diagram - Top Level

  10. Software Development Tools • Before PMD is assembled & operational: • DM240011  - MPLAB Starter Kit for PIC24F • The Kit includes a compiler and a development environment. • It allowed us to develop basic modules. The followings were developed by using this tool: • Accelerometer module • EEPROM interface module • RTCC module • Digital BPF: FFT, basic frequency count algorithm • After PMD is assembled & operational: • Microchip MPLAB ICD 2 • For test and development rest of the software of PMD.
