1. ABSTRACT
RF communications find great applications in our daily. It has got increased priority in security systems, communications, automations etc. The proposed project is a RF based child monitoring system which is practically reliable and easy to install. Radio Frequency based real time Child monitoring and alarm system helps in monitoring the child by the parents. The device monitors the child and produces an alert signal when ever the child passes a certain distance i.e. for instance the system can be des ....etc

Design and Application of Radio Frequency
Identification Systems

Abstract

The recent world, development of effective technologies for linking the object
wireless information is being prompted in various fields. Radio frequency identification
(RFID) is the latest technology for automatic identification which allows the transmission
of a unique serial number wirelessly. The purpose of this paper is to review RFID systems
and its various components infrastructure. The components and features are still under
research and b ....etc

The main goal of this project is to design and develop a short range intelligent digital radio wireless hub. And this hub must be able communicate between adjacent buildings on the campus using digital transmitter and receiver modules(Easy-Radio style). It also must have some interfacing capability like four LEDs for output and four digital inputs, a local USB interface and also mesh interconnection capability. For example,messages could be passed from hub to hub to provide bi-directional communication between them.
Key areas of this project ....etc

Abstract

It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use, you need an efficient way of charging the battery in the phone. But, like most people, you probably don t like being tethered to the wall. Imagine a system where your cellular phone battery is always charged. No more worrying about forgetting to charge the battery. Sound Impossible?
It is the focus of this thesis to discuss the first step toward re ....etc

EMBEDDED BASED RADIO FREQUENCY SPEED CONTROL OF DC MOTOR

The project EMBEDDED BASED RADIO FREQUENCY SPEED CONTROL OF DC
MOTOR is used to varying Speed of The dc motor. It is need a DC to DC converter
is a Circuit Which converts a source of direct current (DC) from one voltage Level to
Another.
Linear regulators output can only in low in low voltage From the Input.
They are very inefficient if the voltage drop is large and the Current high as they
dissipate as heat, a power equal To the product of the output current and the voltage

Radio frequency based real time Child Monitoring and alarm system


INTORDUCTION
Background
The Child Monitoring System is a system which is developed using RF technology to monitor child in a certain area. The system is separated into two parts. This thesis will concentrate more on parent s part while the thesis on child s part will be concentrated by other person. Parents have the master device while the child has the slave device. The master device is sending and recei ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

WIRELESS BATTERY CHARGING SYSTEM USING RADIO FREQUENCY ENERGY HARVESTING



INTRODUCTION AND MOTIVATION

Cellular telephone technology became commercially available in the 1980 s. Since then, it has been like a snowball rolling downhill, ever increasing in the number of users and the speed at which the technology advances. When the cellular phone was first implemented, it was enormous in size by today s standards. This reason is two-fold; the battery had to be large, and the circu ....etc
