Wirelessly Charging Mobile Devices from Ambient RF Sources ABSTRACT: Wireless charging is any of several methods of charging batteries without the use of cables or device-specific AC adaptors. Wireless charging can be used for a wide variety of devices including cell phones‚ laptop computers and MP3 players as well as larger objects‚ such as robots and electric cars. Radio charging is used for charging items with small batteries and low power requirements‚ such as watches‚ hearing aids‚ medical

Chapter 1 Introduction 1.1 Problem 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 dependent on the main supply for charging your cell phone battery or you don’t have the time to recharge your cell phone battery. As technology has advanced and made our phones smaller and easier to use‚ we still have one of the original

1. Introduction Automatic Street Light Control System is a simple and powerful concept‚ which uses transistor as a switch to switch ON and OFF the street light automatically. By using this system manual works are removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. It automatically switches OFF lights under illumination by sunlight. This is done by a sensor called Light Dependant Resistor (LDR) which senses the

ignitrons were developed and ac to dc converters were used to control dc motors. The advent of thyristors capable of handling large current has revolutionized the field of electric power control. Thyratrons‚ ignitrons‚ mercury arc rectifiers‚ magnetic amplifiers and motor generator sets have all been replaced by solid state circuits employing semi-conductor diodes and thyristors. Thyristor controlled drives employing both ac and dc motors find wide applications in industry as variable
