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 ....etc

Radio frequency Identification Based public Transport Management
Radio frequency identification
 Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves.
 It's grouped under the broad category of automatic identification technologies.
The control station con ....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 ....etc

After years of research and development, radio frequency light sources are just now becoming a mainstream lighting option. RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps is that RF lamps operate without electrodes .There are three practical ways to energize RF light sources, though there are more ways to create RF plasmas. These three ways correspond to different types of interaction of electroma ....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

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 ma ....etc

Definition

RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps and conventional lamps is that RF lamps operate without electrodes .the presence of electrodes in conventional florescent and High Intensity Discharge lamps has put many restrictions on lamp design and performance and is a major factor limiting lamp life.

Recent progress in semiconductor power switching electronics, which is revolutionizing many facto ....etc
