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

2. Trochanteric(hip) Padding
Used for Elderly, Sportswear, similar situations
Some discussion on where force from fall was experienced
Padded with foam

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

4. 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

5. 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

6. Schedule October November December January February March April May
Select remaining components
Build experimental setup
Assemble the fall detector
Write fall detection code
Add trigger to device
Add Girdle
Final modifications
