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

5. Scenario (Put some snowy pic here)

6. Technology Optical sensor IR sensor Internet, TCP/IP Database

7. System Overview

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

9. Hardware Designs Temperature Sensor –Method of Usage –Accuracy Pulse Sensor –Method of Usage –Accuracy Hardware Demo

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

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

12. Software User Interface Main doctor window

13. Software User Interface Search window

14. Software User Interface Main patient window

15. Software User Interface User information window

16. Software User Interface Option and Filter Setting windows

17. 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

18. Challenges Hardware and firmware Software and database

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

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