  2. Project Overview • Goal: reduce errors in medical institutions. • Where to start? • Advances in technology … • Biotelemetry & Tracking • How can this be demonstrated: • Collect heart rate signal • Determine approximate location • Transmit data to central computer • Display data in a graphical user interface (GUI)

  3. Project Overview • Objectives: • Uniquely identify personnel • Track personnel or assets • Collect sample vital sign data • Wirelessly transmit & receive data • Associate data with internal records • Display information on GUI • Design devices to be small • Maintain modularity for future improvement

  4. System Diagram

  5. Vital Sign Data Acquisition • Purpose: • Ensure patients’ health and safety • Promote freedom • Design Alternatives: • Body Temperature • Blood Pressure • Heart Signal • Individual Tasks: • Analog signal collection • Filtering • Amplification

  6. Vital Sign Data Acquisition • Advantages: • Non-invasive • More informative • Quality of care • Disadvantages: • More complex design • Common sources of noise

  7. RFID Tracking • Purpose: • Security • Emergencies • Future applications • Design Alternatives: • Global positioning system (GPS) • Wireless transmitters • Radio frequency identification (RFID) • Individual Tasks: • Configuration of transceiver • Transmission of commands • Reception of responses

  8. RFID Tracking • Advantages: • Allows for unique identification • Minimum cost per person • Small physical outline • Modularity • Disadvantages: • Complex low-level design • Accuracy (time domain) • Potential electromagnetic interference (EMI) issues

  9. Wireless Communication • Purpose: • Promote freedom • Save time • Design Alternatives: • MiWi / Zigbee • Bluetooth • Frequency • Individual Tasks: • Setup network • Transmit • Receive

  10. Wireless Communication • Advantages: • Cost savings • Cut the cord • Network integration • Disadvantages: • EMI • Point of failure

  11. Graphical User Interface • Purpose: • Ease of use • Save time • System integration • Design Alternatives: • MATLAB • Visual C++ • LabView • Individual Tasks: • Process received data • Display data

  12. Graphical User Interface • Advantages: • Usability • Centralized • Fool proof • Mobility • Disadvantages: • Upfront design cost • Maintenance
