Silent Drowning
Over 2000 people drown every year in pools staffed
with certified lifeguards due to a lack of real-time
information available to the lifeguard.

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
not adequate and they are
expensive.

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: manikin placed underwater in pool;
tester started clock once fully submerged.

Poseidon TM
•
Cost – the cost of a Poseidon TM system ranges
from $75,000 to $150,000 (High hardware costs)
•
Poseidon uses complex imagery analysis which is
very complicated in difficult environments (murky
water, high amounts of glare)
•
Limited detection – Poseidon TM can only detect
motionless victims on the bottom of a pool and it
does not detect depth

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.

Conclusion
-
Silent drowning is a growing problem
-
The major cause for silent drowning is the lack of
real time information available to lifeguards
-
Our solution informs the lifeguard of potential
drowning victims, so that they can rescue the
person in a reasonable amount of time.
-
Triton can be used in conjunction with Poseidon TM
and other drowning detection systems
