Project Overview Falls are responsible for 70% of accidental death in persons aged 75+ • PFDD is automated system of interconnecting devices to detect user falls • Primary client elderly people living alone. May need help if they fall • Current devices on market require user to press a button to gain help • Estimated development cost $150 • No monthly fee. Presented By: Matthew
Design Goals • Transmitter Package • Fits around neck or ankle • Weight: under one pound • Covers average-size house • Battery life of six months • Receiver Package • Automatically calls emergency service • Prevents “false falls” • Low maintenance Presented By: Matthew
Design Approach - Interface Presented By: Jonathan
Design Approach – Component Diagram Doorbell transmitter Battery Tilt switch Pressure switch Doorbell receiver PIC Automatic phone dialer Emergency contact number Presented By: Jonathan
Design Approach - States Presented By: Jonathan
Project Demonstration • Demo consists of • Setup • Trial process Presented By: Terry
Setup • In dorm room • Student wears PFDD • Pressure sensor connected to bed • Cell phone receives call • Safety mat for student Presented By: Terry
Trial 1 Trial 2 Student in bed Student in bed Student off bed Student off bed Student fall Student in bed Cell phone ring Trial Process Presented By: Terry
Cost Analysis Presented By: Mason
Detecting Bed Pressure Presented By: Mason
Transmitter Battery Life • Transmitter continuously transmits when in bed Possible solutions • Create one-shot circuit for pushbutton and tilt switch • Add repeat circuit with one-shot timer • Modify power supply Presented By: Mason
Chime Output • Output from chime is AC, needs 2-5V DC for PIC Possible solution • Full-wave rectifier built with 5 V regulator Presented By: Joshua
Schedule • Getting parts – 10/29/2009 • Prototyping – 10/20/2009 • Trouble shooting – 11/2/2009 • Soldering parts – 11/9/2009 • Project demonstration – 11/16/2009 • Writing final summary – 11/21/2009 Presented By: Joshua
Current Status • Waiting for final parts • Putting parts together • Deciding on pressure sensor Presented By: Joshua
30% of elderly persons fall each year. Did you know?
