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

2. Trochanteric(hip) Padding
Must be capable of covering
Shoulders.
Sides.
most importantly
Hips
A shirt/coat would best cover all areas
Mostly handy-work, this has been contracted out.

3. Cartridge* & Trigger
For the purpose of inflating the Airbags in the garment. This device must maintain a reservoir of pressurized gas. This would either be filled every so often, or provided with cartridges.
One design employs a 12g CO2 cartridge
Alternate design creates reservoir of air.

4. Air reservoir
Components
Air tank(PVC pipe)
Valves
Servos

5. Fall Detector
Ensure the safety of device wearer by deploying airbag when fall conditions are met.

6. Fall detection components
Arduino microcontroller.
LCD keypad shield
Accelerometer
Ultrasonic Rangefinder
Wires-etc.

7. Construction of fall detecting mechanism
First sewing the sensors onto strips of fabric
Pinning Sensors onto vest
One range finder under front left pocket
Second Range finder on back with accelerometer and microcontroller
Tools for work

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

9. Schedule Current time 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
