1 Welcome to Triton System Prototype v1.0 (Cesar
Barbieri, Dave Larnerd)
The Triton System Prototype is a powerful underwater sensor based tool
designed to monitor swimmers activities. The Triton System is designed to aid
lifeguards by detecting silent drowning cases, promptly alert lifeguards to the dangerous
situation, and identify the victim’s location in the pool. The Triton System Prototype
demonstrates underwater communication of a single RuBeeTM tag and also multiple
RuBee™ tags simultaneously. The prototype demonstrates the ability to register and
administer system users, register and administer swimmers, load swimmers’
information, load different swimmers scenarios, view swimmers’ behaviors in a
simulated pool, detect swimmers drowning, and display a drowning alarm, which can
only be deactivated by authorized users.
This user manual describes the features of the Triton System Prototype and
intends to guide the user through the installation process and software operation;
furthermore, this manual includes a troubleshooting section to help users handle any
encountered errors.
If there are questions regarding the Triton System Prototype, please contact the
Triton Team at Triton@odu.edu.
Thank you,

2 Introduction (Cesar Barbieri, Kate Nguyen)
Over 2,000 children and teenagers drown every year in pools staffed with
certified lifeguards. In 2005, according to the U.S. Centers for Disease Control and
Prevention, there were 3,582 unintentional drowning cases in the United States in which
30% of the victims were children and teenagers (CDCP, 2008). Additionally, drowning is
considered the number one leading cause of death for children under the age of five
and the second leading cause of unintentional injury-related death for children under the
age of fifteen (CDCP, 2007). Unfortunately, the majority of these deaths and injuries are
due to silent drowning. The victims of silent drowning do not splash or display any other
warning signs prior to falling below the surface, and since it occurs so quickly, lifeguards
cannot recognize the situation in time.
The Triton System was conceived as a solution to silent drowning. It was
developed by the Orange Team at Old Dominion University as part of their CS 410 and
CS 411 courses. The Triton System will be capable of wireless underwater
communication by using RuBeeTM technology, registration of system users with different
access privileges, addition and deletion of swimmers, and detection and location display
of a potential drowning victim. The present document describes in great detail the
features, troubleshooting, and installation process of the Triton Prototype; furthermore, it
contains a section on how to operate Triton’s software.
