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.[1] National Center for Missing and Exploited Children (NCMEC), “Analysis of AMBER Alert Casesin 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.

TECHNICAL APPROACH (CONTINUED)• The software system design will be divided in

two levels: the high-level system and low-level system.

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.

RESOURCES• Each NES team member has a topic of expertise. Based on that

distribution review of literature topics and work modules were assigned to each member.

• 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.
