The Problem• In the community, one-in-three people over 65 will fall this

year• This results in 1.8M emergency room visits, 433,000

hospitalizations and almost 15,000 deaths• These falls cost almost $40B annually• In addition, 50 to 75% of nursing home residents fall each

year resulting in 1800 deaths• One injurious fall increases nursing home costs by

$5325/yr• Over half of the elders who fall are unable to get up

without assistance and after a fall “longer times spent helpless…were associated with the person’s being found dead or being transported to the hospital, being admitted, and being discharged to other care rather than to independent living.”



Solution Objectives• Detect falls without the elder having to do

anything, wear anything, push any buttons• Should be as reliable as a smoke detector• Assumed elders are living alone with no technical

help and little money• Low cost – in residential settings, probably

offered using a leasing model with PERS• Very simple - installed by elder• Integrates into existing PERS infrastructure• False negatives are worse than false positives

Sensor Overview•4” x 6” surface- or flush-mount sensor

•Battery Powered (3xAA)•Battery life of > 1 year•Panic Button•Nurse call interface (including power)

•Pears with any PERS system•Patent pending optical sensing system creates zones and a proprietary algorithm looks for unique fall signatures

•Mounted ~12” above floor

Simple Algorithmic Concept

A “true” fall is fast and uncontrolled motion toward the floor. A large amount of energy moves from the top field into the bottom field relatively quickly. The signals should be well correlated in time. The activity in the top and bottom fields sensed before and after the fall should be consistent with the circumstances expected during a fall.

Some Newer Developments• Over the last 9 months, this smaller, lower cost,

more accurate sensor was developed• It turns out this system also reliably detects a

person getting out of bed (GOOB)…• …it also detects “restless sleep”• These new features make the system very

appealing for institutional settings (skilled nursing and assisted living)

• Now initially focusing on institutional settings –large benefit, professional installations, more controlled data, “cleaner” channel

• “Close” to signing an exclusive agreement with a partner for these markets

• Unclear what to do about residential markets –what is your advice?
