PROBLEM STATEMENT


Child kidnapping is a real issue nowadays.


The threat of having their child kidnapped causes great
concern to parents.


In 2011, 158 AMBER Alerts were issued in the United
States (including Puerto Rico) related to child abductions
cases involving 197 children [1].


Novotech

Engineering Solutions (NES) goal is to develop a
device by which parents can monitor the location of their
children, therefore preventing potential kidnapping cases,
or facilitate the task of finding a child that has already
been kidnapped.

in 2011”, NCMEC, Alexandria, Virginia, Amber Alert Rep., 2012.

PROJECT SOLUTION AND DELIVERABLES



NES proposes to create
Life Connection
:
The Child
Security Alert Bracelet
, a small but powerful bracelet with
the following security features:



Track the location of the child wearing the bracelet



Provide the child's pulse rate



Provide the temperature at the wrist for statistical comparison to
aid in location changing.



Unauthorized removal mechanism



Web
-
based and Android user interfaces



Central Database for storing location and sensor data, along with
user account information.

MARKET COMPETITION


Products like Amber Alert GPS have been
developed to provide the current location of the
child.


Amber Alert GPS provides:


Locate via Computer or Application


SOS Button


Low Battery Alert


Predator
Alert


Monthly Recurring Payments Costs

OBJECTIVES


Design and implement a
location tracking system

by using assisted GPS
that notifies about the current location of the child even indoors, remote
or far away locations
.


Design and implement a
communication system

by using a GSM
network that allows sending data packets containing device data
(temperature, pulse and location) to be stored on the database.


Design and implement a
pulse sensor
that reads data about the child’s
pulse through the application or web interface.


Design and implement a
database system

to collect, manage, and share
all information about the child’s conditions and location on a specified
time span.


Design and implement a
temperature sensor
that reads data about the
child’s temperature at the wrist through the application or web interface.


Design and implement an
unauthorized alert remove mechanism
that
sends notifications if the bracelet has been removed through the
application or web interface.

OBJECTIVES (CONTINUED)


Design
and implement a
web user interface
that sends notifications
about the status and location of the child as well as the bracelet status
on a web application
.


Design and implement an
Android application
that sends a notification
about the status and location of the child as well as the bracelet status
on Android based mobile devices.


Design and implement a
battery holder
to power up the microcontroller.
The battery holder must be a compact, space saving, non
-
intrusive tray,
and can’t interfere with the removal mechanism to ensure bracelet
comfort.


Design and implement a
battery level indicator
that sends notifications
to the application or web interface. An on
-
board indicator about the
battery level and if it needs to be charged will be implemented.

MANAGEMENT APPROACH


Regular scheduled and on
-
call meetings will be held every week.



The completion of each task will be ensured by applying the Divide and Conquer
technique, therefore we divided this project into the following main sections:


Embedded System Specifications,


System Digital Design


System Physical Implementation


System Unit Testing


System Integration and Testing


Final System Delivery



The Project Manager is responsible for overseeing the progress and status of
each of these sections.


Each section will be divided into 7 modules, and an assessment
will be done on
each module by determining its completed percentage from the module definition
and goal.


When
all modules are
completed the
main section
is will be completed.


Agile software development methodology will be used, focusing on continuous
customer or stakeholder involvement, and close, daily co
-
operation between
developers.

The Life Connection bracelet will
likely have social and economic
impacts. An expected social impact is a sense of relief on
families because this bracelet will allow them to monitor where
their children are at any moment, providing a safer community.


If bugs
or system failures
occur or hackers break into the
communications system they may be able to
access the
information in order to locate the bracelet and the child. This
security issue will be of real concern to parents.

CONCLUSION



At
Novotech

Engineering Solutions, we want to offer
parents a product, by which they can remotely track and
monitor the location and well being of their children,
more mobile and compact than any other currently in the
market.


In the long run, we believe this product could aid law
enforcement agencies on kidnapping cases, and greatly
improve the chances of finding missing children before it
is too late.
