The Astronaut in a Hostile and Remote Environment

  • Apprehend the physiologic status
  • Collate the data
  • Interpret the data locally
  • Propose and realize a response
  • Record the event and transmit to a distant management site
  • Design, validate and implement sensor network for semi-autonomous physiological monitoring system.
analogies for assistive technology requirements
Analogies for Assistive Technology Requirements
  • Medical situations or probabilities that require prompt response and might otherwise confine the individual to a strictly monitored environment
  • Desire for maximal independence of mobility and location
  • Need for local prompt alert and response while maintaining strong connection to a distant management site
  • Great technical solutions for sensing, data management and telecommunications awaiting application
