Más contenido relacionado Más de Laura Mitchell (11) Fall Prevention AgeTech Call 1 28 102. 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.”

3. 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

7. 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.

10. 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)

Basic Proof of Lab Field Lab Field Production
Research Concept Proto 1 Testing Proto 2 Testing Prototype
• 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?
