Inflating Padding Antifracture Girdle ET Senior Project Design Fall 2014 Stephen T. Calvert Advisor Dr. Patrick McDowell

Trochanteric(hip) Padding Currently existing models available Used for Elderly, Sportswear, similar situations Most currently use foam for padding, which is minimally effective.

Cartridge & Trigger  Accepts signal from fall detector  Releases cartridge gases when signal received  Cartridge contains 6 liters of gas to inflate padding

Fall Detector Three accelerometer design discussed Use of Gyro’s discussed Settled on a design using one accelerometer together with a distance detector Arduino used due to greater familiarity

Tasks  Obtain appropriate sensors(accelerometers, gyros, etc)(in transit)  Build experimental setup for fall detector.  Test fall detector, modify as necessary  Determine appropriate trigger mechanism(purchase if modifiable version is available)  Test and modify  Build girdle with CO2 bladders  Assemble all parts  Test prototype  Make modifications as necessary  Write up on device

Schedule OctoberNovemberDecemberJanuaryFebruaryMarchAprilMay Select remaining components Build experimental setup Assemble the fall detector Write fall detection code Add trigger to device Add Girdle Final modifications
