  1. Fall Detection System Development Proposal phase 2

  2. Results of Previous Phase Using acceleration signal of the body • Measure Accelerations (no other sensor necessary, but can be added if required) • Process data • Fall detection algorithm based on max difference formula

  3. Power Consumption

  4. Battery • Lithium Polymer • Very high energy density • Low weight and high cell value (3.7V) • Distribution is possible with low capacity multiple cells • Specifications • Capacity: 160mAh • Weight: 3.5g • Dimesions: 12 X 35 X 5.5 mm

  5. Battery Life • Some elementary calculations • Total current consumption: 500mA • Total power consumption @3.7V: 1.85mW • Battery discharged state: 20% or 3.5V • Battery charged state: 95% or 4.1V • Total power available: 75% of 160mAh • Estimated days of operation: 10days

  6. Pictorial View of the System
