FallSafe Sketch Model Review b | 2.009 Fall 2013

FallSafe: Market 250K hip fractures among elderly in 2010 95% of hip fractures are fall- related 1 in 5 patients die within one year of injury 2.009 Fall 2013

FallSafe: Product Goals Core Functionality Deployment system inflates Communication system calls Inertial Sensor Detects Fall airbag prior to impact for help Other Requirements Possible Implementations -Detector & Inflator module with -Easy to remove from fallen user disposable airbag belt -Low visibility before deployment -Replaceable gas canisters/charges -Permits discrete use 2.009 Fall 2013

FallSafe: Key Risks Fall Detection Injury prevention Airbag Deployment 2.009 Fall 2013

FallSafe: Key Risks Reliability Fall Detection False Positives Time available to deploy airbag Injury prevention Airbag Deployment 2.009 Fall 2013
