  3. Design Requirements

  4. ! X X SMS Text Alert System Design Requirements

  5. Evolution of the Wireless Biosignal Monitor Amplifier   Breadboard (NI Elvis Board) Circuit board Printed Circuit Board http://visual.merriam-webster.com/images/science/physics-electricity-magnetism/electronics/printed-circuit-board.jpg zone.ni.com/cms/images/devzone/tut/04150816.JPG

  6. Wireless Technology • SYNAPSE Wireless • Advantages • Inexpensive • Easily encrypted (Security) • Low power • Range up to 1000ft indoors • Establishes Mesh network Mesh Network SNAP stick SNAP Node ProtoBoard All images taken from www.synapse-wireless.com

  7. ECG Signal • Bioelectric signal • Displays the voltage difference • Einthoven’s Triangle Image taken and modified from http://www.medicine.mcgill.ca/physio/vlab/cardio/images/einthoven.jpg

  8. SMS Messaging for Emergency Response Normal ECG? ECG signal aquisition Data to EMR SMS Text Alert NO

  9. Incorporation of RFID technology to quickly identify which patients are using which devices • Multiple Signal Channels Future Improvements
