PMD – Parkinson Mobile Device (*)

PC

(*) - There are 2 versions of PMD developed: minimal/basic (small box) & enhanced (big box).

Agenda

• Functional description of the system

• Description of performed project’s activities until now

• Description of future project’s activities

• Budget & Costs

• 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.

Functional Description Of The System

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.

Software Development ToolsBefore 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.
