saw the development of high-power microwave emitters known as cavity magnetrons‚ the idea of using microwaves to transmit power was researched. In 1964‚ William C. Brown demonstrated a miniature helicopter equipped with a combination antenna and rectifier device called a rectenna. The rectenna converted microwave power into electricity‚ allowing the helicopter to fly. In principle‚ the rectenna is capable of very high conversion efficiencies - over 90% in optimal circumstances. Most proposed MPT systems

are voltage-gated ion channels‚ though certain types of these channels need accessory ions to open properly (Shier et al. 2004). Four types of potassium ion channels will be discussed in this paper. According to Moyes and Schulte (2006)‚ delayed rectifier channels open in response to a change in membrane potential‚ repolarizing after an axon potential. The A channel (KA channel) makes the neuron more excitable as it opens when the neuron is depolarized. Inward

CHAPTER 1 INTRODUCTION This project is mainly used to save power automatically instead of doing manual by using IR sensors The main consideration in the present field technologies are Automation‚ Power consumption and cost effectiveness. Automation is intended to reduce man power with the help of intelligent systems. Power saving is the main consideration forever as the source of the power(Thermal‚ Hydro etc.‚)are getting diminished due to various reasons. Wireless communication
