Concept

• Give consumers access to their personal
  physiological data.
• Wireless network of sensors on the body to
  process and record EKG, pulse oximetry, and
  location data.
• More flexible than competing products, with an
  easier-to-use User Interface.

Goals

• Provide accurate data to the user
• Reliable data transfer from the device to the
  computer
• User friendly User Interface
• Accurate data analysis using graphs

Experimental Campaign

• Sensor Nodes
• Data Transmission (Reliability)Test for dropped
  packets and re-transmits.
• Sensor Server
• Startup (Reliability)Devices activate in a
  coordinated fashion. Data log system starts
  cleanly. Test repeated startup/shutdown sequence.
• Pairing with computer/Data upload
  (functionality)Test connection between computer
  and Sensor server Specifically, try the cases of
  sensor server power failure, computer power
  failure, Bluetooth interference.
• Test aggregating data (Functionality)-we want all
  data to be transmitted well -collect two or more
  types of data and upload all of them fault-free.
• Shutdown (Reliability)Test clean shutdown case
  (Sensor server issues shutdown commands to
  motes), power failure recovery (of motes), and
  salvage of partial data in gumstixpower failure.
• Computer
• Error catching (Reliability) Test computer side
  code for correct response to corrupted or illegal
  data.
