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

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

circuit diagram of traffic light priority control for emergency vehicles

Abstract

Biologically inspired approaches have the potential to solve many of the difficult networking problems awaiting practical solutions. The recently proposed Virtual Traffic Lights (VTL) is one example (or instance) of this powerful approach for solving some fundamental transportation problems, . The successful operation of VTL scheme ultimately depends on the local rules used by vehicles approaching an intersection for electing a leader that manages the traf ....etc

Remote device control using Radio Frequency

The project compares the communication of control signals using radio frequency
and Infra Red Rays. The STR is ideal for short-range remote control applications where
cost is a primary concern. The receiver module requires no external RF components
except for the antenna. It generates virtually no emissions, making FCC and ETSI
approvals easy. The super-regenerative design exhibits exceptional sensitivity at a very
low cost. A SAW filter can be added to the an ....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 system design is a topic of interest to multidisciplinary fields including electrical engineering and computer science. In order to correctly focus on the correct aspects of embedded system design, be it hardware for electrical engineering students, or software for computer science students, seamless connectivity between the hardware and software aspects needs to be provided. One approach to provide students from both fields with practical experience is to develop a transparent bridge between the hardware and software layers of the e ....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
