WEEK 6 FYP

Objectives   : o To explain the details about the project
                    o To know the objective of the project

Activities     : For the past week, i have study about the wireless system operation, RF transceiver and also child safety harness invention. From the information i collect and research i have made, i have started doing my proposal. For this week, i have came out with the introduction, objective of my project.

Analysis      : The details are shown below:

 INTRODUCTION & CONCLUSION:

Introduction

The objective of my project is to develop Remote Security Alarm for wireless child safety harness with tracker. Nowadays, we have heard many cases about missing child and kidnapping on the television or other media. So, I have design something that can be used to solve this problem. This wireless child safety harness with tracker actually has been designed to protect child from missing or kidnapping in a busy environment. I have design 3 circuit for this project and prepared 1 tracker devices. The circuit that being prepared is transmitter, receiver and alarm circuit and also the tracker devices.  My project is very easy to use and very comfortable. It can be hold or bring anywhere because of its size is small and light. I have use 9V battery for both of the circuit. The receiver and alarm circuit will use the same battery. The alarm circuit will activate and give a warning sound if the receiver is not receiving a signal from the transmitter. So it is the warning sign for the parents if their children are far from them.

Objective

In this busy environment, parents sometimes neglect the importance of their children safety. The main objective of this project is to develop wireless child safety harness with remote security alarm fixtures and tracker device. The purpose of this invention is:

Ø  to protect the children from being missing or kidnapped especially in crowded place such as shopping complex.

Ø  To allow parents freely do their activities such as shopping, working while the kids are monitored with the device.

Ø  To upgraded the existing child harness from rope child harness to wireless child harness.

Ø  To make parents and child feel comfortable and easy to bring that devices because it was small and light.

It is believed that this project can reduce the number of missing children or kidnapping. In today's world, technology is not what we want but i was what we need. Everyone is hungry for technology. Even some parents don't want the technology because it's expensive, but sooner or later they will buy it because it is needed to archive developed nation.

 

WEEK 5 FYP

Objectives   : o To study the details about child safety harness
                    o To know the history for the child safety harness

Activities     : For week 5, i do some research about safety harness. I have learned about the child safety harness definition, and the previous work about this child safety harness. I have to collect the data about the safety harness for child because my FYP idea is to upgraded the existing child safety harness to wireless child safety harness with tracker.

Analysis      : The details of traditional child safety harness are shown above:

 DEFINITION & PREVIOUS WORK:

Definition Of Child Safety Harness

A child harness is a safety restraint for walking with children. The device is mostly used with toddlers and children of preschool age, and typically consists of a shoulder harness with a lead secured in the back, either directly or by means of a hook. When the device is used, a child wears the harness and a parent or a guardian holds the end of the lead or attaches it to their wrist. This allows the child relative freedom of movement in comparison to being seated in a stroller, carried by the adult (with or without a child carrier), or being held by the hand. At the same time, the child harness prevents child separation from the adult by the way of the child running off in a crowded or dangerous area. There exists a difference of opinion on the use of child harnesses. Those in favor argue for the benefit of enhanced safety, and increased freedom of movement compared to hand-holding or confinement of children to strollers. Those opposed to their use prefer restraining children through hand-holding, and point out that harnesses prevent children from learning that if they act up or try to run away they will not get to go places. The child safety argument has been winning over in recent years and the use of the safety harness has increased.

Child Safety Harness Previous Work

Many parents asked for a security device which could get them "peace of mind". Since the 1990s, many manufacturers worked on a more human harness for kids. Such manufacturers as Mother care or Boots in United kingdom, Safety First or DANDee in the United States and many others produced many models varying in texture, colours, and width which varies from 15cm to a maximum of 60cm to 80cm. More and more, harnesses appear to be light weight and extremely resistant at the same time. They are made mainly in England and can be found on some specialized internet stores. They can often be bought at the entrance of some amusement parks. Because many parents are reluctant to leash their children, a new device is coming to be on sale more and more. The reason why a parent will use a harness is for helping the child to walk or for restraining the moves of the child. By way of consequence, a harness needs to be linked to a solid rope which will be clipped to the harness buckles. The terms used to name this rope are varied and different from a place to another. We can classify them in two broad categories. A rope for helping babies of a year to make their first steps. The appropriate term is leading Strings. A rope for restraining movements of a child or used as a security device when in crowd, on chair or in a pram, or stroller. The words reins, leash, tethers or lead are the appropriated terms here.

WEEK 4 FYP

Objectives   : o To study about wireless system
                    o To study about transceiver (Transmitter & Receiver)
                    o To study about Radio Frequency (RF)
Activities     : On this week, i have study and do some research about the wireless system, RF transmitter & RF receiver. It is because in my project, i use this RF features to create a wireless network. I can change the frequency according to the required distance by using RF (Radio Frequency) system.
Analysis      : The details of my research are shown above:

 WIRELESS, TRANSCEIVER & RF:

Wireless

The word wireless is dictionary defined as "having no wires". In networking terminology, wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and/or microwaves to maintain communications.

Transceiver

Transceiver is short for transmitter-receiver, a device that both transmits and receives analog or digital signals. The term is used most frequently to describe the component in local-area networks (LANs) that actually applies signals onto the network wire and detects signals passing through the wire. For many LANs, the transceiver is built into the network interface card (NIC). Some types of networks, however, require an external transceiver. In Ethernet networks, a transceiver is also called a Medium Access Unit (MAU). In radio communications, a transceiver is a two-way radio that combines both a radio transmitter and a receiver that exchanges information in half-duplexmode.

RF (Radio Frequency)

Short for radio frequency, any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. These frequencies make up part of the electromagnetic radiation spectrum:

• Ø  Ultra-low frequency (ULF) -- 0-3 Hz
• Ø  Extremely low frequency (ELF) -- 3 Hz - 3 kHz
• Ø  Very low frequency (VLF) -- 3kHz - 30 kHz
• Ø  Low frequency (LF) -- 30 kHz - 300 kHz
• Ø  Medium frequency (MF) -- 300 kHz - 3 MHz
• Ø  High frequency (HF) -- 3MHz - 30 MHz
• Ø  Very high frequency (VHF) -- 30 MHz - 300 MHz
• Ø  Ultra-high frequency (UHF)-- 300MHz - 3 GHz
• Ø  Super high frequency (SHF) -- 3GHz - 30 GHz
• Ø  Extremely high frequency (EHF) -- 30GHz - 300 GHz
