The Parkinson’s patient often suffers from involuntary seizures, that are unnoticeable to him, but tire his muscles and cause great pain.

The appearance of the tremor is random. Muscles’ behaviour is very similar to that, as they were intensively used during some kind of hard work.

Parkinson’s patient must have a periodic physiotherapeutic treatment, in order to relief the pain, caused by the cramped muscles.

Patients can significantly improve quality of life, if were given some kind of an “alarm”, when the tremor starts. Consequently, the unwanted tremor can be stopped and the seizures of the muscles can be prevented.

Design a portable low-power system which: Identifies presence of tremor. Analyzes vibrations and detects a Parkinson’s tremor. Notifies the user about appearing of unwanted tremor (“alarm”). Enables better tracking of the disease by storing data, describing

specific tremor’s appearance, like: Starting time Duration Strength (amplitude) Frequency

Runs on a daily basis, powered by rechargeable battery, that is recharged by the solar cells or by connection to the external power source. Low battery indicator alerts user when battery is low.

Project’s Goals

Page 6: Parkinson ’s patient & doctor  aiding system

Project’s Goals (continuation)• Designing PCB and appropriate packaging, resulting in a small

low-power Portable Mobile Device (PMD), like an ordinary wrist watch.

• Creating a unique set of software for PC and PMD, which enables performing of the following tasks:

Downloading data from portable device. Performing of the data processing on downloaded data and

displaying the appropriate statistics on PC. Creating database and storing it for the further inspection by

the patient / doctor.

Page 7: Parkinson ’s patient & doctor  aiding system

Project’s Overview (semester A)Stanislav and Barukh:

• Choosing components for the project, suitable for low-power applications.

• Designing a digital part of the project (schematics).• Designing, manufacturing and assembling of the PCB for PMD.• Performing basic debug.

Alexander:• Designing the power part of the project (solar cells, battery recharge

and power managing).• Designing and production of the appropriate packaging for PMD.• Assisting to Stanislav and Barukh in the integration between power

and digital part of the project and the items related to production of PCB.

Page 8: Parkinson ’s patient & doctor  aiding system

Project’s Overview (semester B)Stanislav and Barukh:

• Debugging the hardware of the PMD device.• Designing software for embedded hardware of the PMD that

includes recognition of the unique nature of Parkinson’s tremor and storing the basic parameters on the PMD’s memory.

• Creating low-level drivers for basic interface to the PC

Alexander:• Assisting to Stanislav and Barukh in the debug of PMD.• Designing a unique high-level software for PC, that enables

communication with PMD, creating the database, performing various graphs and storing the database for further inspection by patient / doctor.

Technical Requirements• Autonomous portable system worn on the Parkinson’s patient wrist.• Recognition of a unique nature of Parkinson’s tremor (2÷10 Hz).• Recognition of maximum 2 Parkinson’s attacks per minute.• Storing of the parameters describing each Parkinson’s attack in the

non-volatile on-device memory.• Minimal period for storing the parameters - 7 days.• Low-power rechargeable battery application.• Alert for “low-battery” state.• Notification to patient on appearing of Parkinson’s attack by:

Vibration (depends on vibration motor availability) Buzzer / LED indication.

• Physical dimensions of the PMD are like ordinary wrist watch.• Interconnection to PC for performing extended data processing and

better tracking.
