Design Specification

Progress: Design Specification



USB Hub: 5V Raspberry Pi: max 515 mA Bluetooth Dongle: 100mA

Touch Screen: 12v with 660mA Blood Pressure module: 12v at 645mA

Progress: Power Supply Analysis

Progress: Power Supply Analysis

Progress : Design Specification



Project Specification: System must be contained within an enclosure Dimensions of the Touch Screen display

dictate the overall size of the enclosure 3D printed

Progress: Enclosure Analysis

Began Analysis from cardboard model Constructed 3-D model in Solid Works Equipment Layout Analysis using 3-D model Printed Enclosure

Special thanks to Dr. Patterson for his many contributions to the project

Progress: GUI demo

Continua Compliance:Explanation

Continua Compliance:Semester Plan

Continua Compliance:Semester Plan

Planned for difficulty 2 weeks Fall 2013 8 weeks Spring 2014

Pushing into time allocated for debug 3 additional three weeks

Total ~13 weeks for Continua Compliance

Continua Compliance:Methods Attempted

RFCOMM : Redesign Bluetooth Antidote: Continua compliant service Oximeter HDP tutorial HDPy repository

AND Blood pressure pump to Linux computer Contact HDPy developers

Linux to Linux spoof oximeter data example Linux to Linux spoof blood pressure data

Android Application

Android HDP Application

Android application that supports the Health Device Protocol standard with Bluetooth capability.

Likely has error in the stack

Wrap Continua Communication in C programming wrapper

Establish auto-pairing between manager and agent

Create Continua Compliant Android sink

rate)

Controls:Environment of testing, person who’s blood pressure is beingmeasured

Plan: Testing

Test name: Function properly with extended runtime

Independent variables:Time elapsed

Dependent variables:Device functionality: Able to take and view blood

pressure reading

Controls:Testing environment

Plan: Testing

Test name: User setup and run without instructions

Independent variables:User selected

Dependent variables:Time for user to view their blood pressure

Controls:Withhold instructions, method of seeking feedback,testing environment

Plan: Testing

Test name: Behavior with various data interruption

Independent variables:Method of interruption

Dependent variables:After connect is reestablished, if data passed continues

tobe passed without an error

Controls:Test environment, trials per independent variable

Plan: Testing

Test name: Interface to Continua Devices

Independent variables:Device used as agent

Dependent variables:If correct data is passed from agent to manager

Controls:Test environment, managing device

Plan: Testing
