Silent Drowning

• Over 2000 people drown every year in pools
  staffed with certified lifeguards due to silent
  drowning.

Recent Drownings

• June 20, 20074-year-old Wakefield Girl Drowns
  Great Wolf Lodge in Williamsburg,
  VA
• July 4, 2007 Lifeguards Unable To Revive
  29-year-old Woman In Wave Pool (Splashin' Safari)
  Holiday World in Santa Claus, IN
• July 13, 20074-year-old Boy Drowns In Wave

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.

7
Lifeguard Challenges

• Ellis Associates study of lifeguards
• Vigilance capacity only 30 minutes
• - Heat - Noise / Distraction - Monotony -
  Stress - Fatigue - Poor diet - Dehydration

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.

12
Triton Solution

• GOAL Provide an effective, reliable, low cost
  system that will decrease silent drowning
  incidents at pools and waterparks around the
  world. It is our commitment to meet this goal
  and seek continued innovation and solution
  improvement.

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.

• 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
