Purpose • Manage the Disease using Remotely Monitoring – Improve overall outcome in the patient’s health status – Early intervention – Decrease in number of hospital visits

Scenario • (Put some snowy pic here)

Technology • Optical sensor • IR sensor • Internet, TCP/IP • Database

System Overview

Design • Hardware – Sensors – Interface • Firmware • Software and Database – User interface • Multi-user design

Hardware Designs • Temperature Sensor – Method of Usage – Accuracy • Pulse Sensor – Method of Usage – Accuracy • Hardware Demo

Firmware Designs • 10 base. T Ethernet interface • Easy access of data record for any patient. • Real time feedback • Affordable • C code implementation, portability to other platforms, facilitate future enhancement

Software Designs • User Access – Doctor and client modes – Windows GUI client application – View data and modify settings • Database (My. SQL) – Accessible by firmware and client software

Software User Interface • Main doctor window

Software User Interface • Search window

Software User Interface • Main patient window

Software User Interface • User information window

Software User Interface • Option and Filter Setting windows

Multi-User Design • Each user is identified by an unique ID • Each patient is associated to a machine by machine ID • Data sent and store to the database according to user and machine ID pair • User switching by changing user and machine ID association

Challenges • Hardware and firmware • Software and database

Hardware/Firmware • Incompatible temperature sensor SPI interface • Limited external interrupt • Integration Problem

Software/Database • Communication with microcontroller – User switching • Many-to-many association between doctors and patients

Business Components • Budget • Actual cost

Budget Components Estimated Price Rabbit 2000 TCP/IP Development Kit $250. 00 Pulse Sensor $80. 00 Temperature Sensor $60. 00 Cable/Wires $25. 00 Case $30. 00 USB Serial converter $50. 00 Total Cost (10% contingency) $550. 00

Actual Cost Components Actual Price Rabbit 2000 TCP/IP Development Kit $250. 00 Pulse Sensor $50. 00 Temperature Sensor $200. 00 Cable/Wires $0. 00 Case $15. 00 USB Serial converter $30. 00 Total Cost $545. 00

Cost Comparison • Estimated cost: $550. 00 • Actual cost: $545. 00 – Overspent – Backup parts • Actual product price: $150. 00

Future Expansion • Hardware/Firmware • Software

Hardware/Firmware • More sensors – Blood sugar level – Blood pressure • LCD display • Video/Audio conference • Wireless internet/communication

Software Expansions • Automatic notifications of critical health condition • Report generation – Graphs and statistics • Secure data transaction – From firmware and database
