Team 3: Decision Making

We will discuss important issues and make
logical and objective decisions based on
gathered information and consensus

If consensus can not be met, a majority rule
will be supreme

SMART Seat

Existing problem arises that there is no adequate way to electronically turnoff
the passenger side airbag. As of now, the primary method is done manually by
the turn of a key. Problem persists that if a user forgets to turn off the
passenger side airbag, a child can be severely injured or killed.

Second problem arises is where the passenger is located when the Airbag
inflates. If the passenger is leaning forward, slouched down, or a child, we do
not want the airbag to activate with the same amount of force. Our seat would
determine where the passenger was sitting along with the passenger size and
constantly update and control the needed force to safely inflate the airbag so
the airbag does not do more harm than good.


Various sensors integrated into a web of sensors to determine if a human
being large enough to safely activate the passenger side airbag.

Oil Level Sensor

To measure level of the oil in an engine (on a
lawnmower) at any given moment, considering the
high temperature, different inclines.

Could be separated into different blocks. Also
might need a circuit, that would amplify that given
signal if necessary. Also a circuit that would shut
off the engine if there is no oil, or if oil is too low.





Will be mainly used for residential home owners who
own a pool and also are parents to young children
Over 300 children under the age of 5 every year drown
in home swimming pools
This product will activate an alarm signaling that a small
child has fallen into the pool without the supervisors
knowledge
Alarm can be manually turned off
Solar cell panel for daylight recharging of batteries
Secondary function could be to detect unwanted
intruders into your pool at night

The poolside saver will be built to safely monitor and
determine the existence of young children near a pool. The
existence of a young child, near the pool without proper
supervision from a nearby adult, can easily fall into and drown
within seconds. Our product will determine if the child has
fallen into a pool and send off an alarm inside and outside the
house to alarm nearby patrons. Our product will also report
the water temperature, air temperature, etc. to a remote
indoor display.

Key Risk Areas
 Developing
and implementing a wave sensor
could be very complicated
 Not much market on workable child safety
poolside devices
 Prototyping would be hard. Can not carry
large pool into EMS building
 Outdoor design requiring waterproofing
 Needs to be near foolproof, should not go off
with falling branches, excessive wind, etc.

1: Patent # 6,727,819
 A pool guard alarm provides constant security at
one or more entrances to a pool area. The alarm
utilizes a delay timer to provide an authorized
entrant the ability to enter the pool area and reset
the alarm before an audible alarm is sounded. The
alarm further guards against pool entrances being
left inadvertently open by sounding an audible
alarm if a pool access point is not closed within a
specified time period after being opened.

2: Patent # 6,583,724; Pool Alarm System
A pool alarm system for alerting when an object such
as a child has entered a pool filled with water. The
pool alarm system includes, a sensor assembly for
detecting when an object has entered the water in a
pool. The sensor assembly includes a housing that is
mountable on a side wall of the pool. A first sensor is
mounted on the housing for detecting movement of
the surface of the water. A warning assembly is
provided for warning an individual in a vicinity of the
pool that the sensor has been activated.

3: Patent # 6,259,365; Laser Security Fence Apparatus
A laser security fence apparatus is disclosed for providing a warning
signal in response to an intruder of a restricted area. The apparatus
includes a laser generator for generating a laser beam and a first
mirror aligned with the laser beam for reflecting the beam. A second
mirror is aligned with the first mirror for reflecting the beam reflected
by the first mirror and a collector is aligned with the second mirror for
collecting the beam reflected by the second mirror. A microprocessor
is associated with the collector and the generator for sensing when
the beam is broken by the intruder so that the beam is not received by
the collector. An alarm is connected to the microprocessor for
actuation by the microprocessor when it senses that the beam is
broken so that the alarm provides the warning signal.
