Drowning
•
“Six people drown in U.S. pools every day. Many of these pools are public facilities
staffed with certified professional lifeguards.”
--Centers for Disease Control
•
“19% of drowning deaths involving children occur in public pools with certified
lifeguards present.”
--Drowning Prevention Foundation
•
“Drowning is the second-leading cause of unintentional, injury-related death among
children under the age of 15.”
--National Center for Health Statistics
•
“Drowning is the 4th leading cause of accidental death in the United States, claiming
4,000 lives annually. Approximately one-third are children under the age of 14.”
--American Institute for Preventive Medicine
•
“A pool is 14 times more likely than a motor vehicle to be involved in the death of a
child age 4 and under.”
--Orange County CA Fire Authority

Additional Consequences
•
For every child who drowns, four are hospitalized for near drowning.
American Academy of Pediatrics
•
Non-fatal residual effects of drowning
- Brain Damage
- Lung Damage
- Acute Respiratory Distress Syndrome (ARDS)
- Aquatic phobia
•
initial medical treatment costs at least $75,000 and about $250,000 a
year for long-term care. The cost of a single near-drowning that
results in brain damage can be more than $5.5 million.

What Are We Doing About It?
Many parks have added
more lifeguards and
installed various drowning
detection systems (such as
Poseidon TM) in response to
silent drowning. These
attempts at a solution are
expensive and have proved
inadequate.

Jeff Ellis & Associates Firm
•
International Aquatic safety and risk management
consulting firm that has revolutionized lifeguard
training in the U.S.
•
Study – how quick lifeguards could spot swimmer
in trouble underwater. 500 tests at more than 90
locations varying sizes and lifeguard staff.
•
Each case: mannequin placed underwater in pool;
tester started clock once fully submerged.

Market Analysis
Would your organization be interested in technology
that would help prevent or reduce drowning
incidents?
Aquatics Director Prince William County Park Authority:
“Always, Anything that will help prevent or reduce the
likelihood of a drowning would be worthy of
exploring.”
Ocean Breeze water park manager:
“Yes, but cost is a major consideration.”

RuBee Characteristics
• Magnetic Spectrum: RuBee uses a 131 kHz
carrier which is entirely magnetic, therefore the
protocol is almost unaffected by harsh
environments.
• Active Xmit: RuBee tags are radiating
transceivers and actively transmit their own signal,
where as RFID tags work in backscatter
transmission mode and just reflect radio signals.
• Sensor add on: RuBee tags can be outfitted with
sensors and have a small 4 bit CPU with a small
amount of memory on them.

Risk Management Plan
• Identify project risks
• Determine the phase that the risk is in
• Categorize risks according to probability and impact
• Reduce risks before or as they happen with
mitigation actions
• Continue to reevaluate risks during all phases
• Watch for new risks
