Microwave Engineering by Pozar mediafire link

Focusing on the design of microwave circuits and components, this valuable reference offers professionals and students an introduction to the fundamental concepts necessary for real world design. The author successfully introduces Maxwell's equations, wave propagation, network analysis, and design principles as applied to modern microwave engineering. A considerable amount of material in this book is related to the design of specific microwave circuits and components, for both practical and motivational value. It also presents the analysis and logic behind these designs so that the reader can see and understand the process of applying the fundamental concepts to arrive at useful results. The derivations are well laid out and the majority of each chapter's formulas are displayed in a nice tabular format every few pages. This Third Edition offers greatly expanded coverage with new material on: Noise; Nonlinear effects; RF MEMs; transistor power amplifiers; FET mixers; oscillator phase noise; transistor oscillators and frequency multiplier.

GSM mobile based car control Project

A   remote   control   vehicle   is    defined   as     any mobile  device  that  is  controlled by  a  means  that  does  not restrict its motion with an origin external to the device. This is often   a         radio  control     device,   cable      between  control  and vehicle,  or  an  infrared  controller.  A remote control  vehicle (Also called  as RCV)  differs  from  a robot  in that  the  RCV is always controlled by a human and takes no positive action autonomously.

One of the key technologies which underpin this field is that of remote vehicle control. It is vital that a vehicle should be capable of proceeding accurately to a target area; maneuvering  within that area to   fulfill    its    mission  and returning equally accurately and safely to base.

Microcontroller Based Solar Tracking System

Renewable energy solutions are becoming increasingly popular.  Photovoltaic (solar) systems are but one example.  Maximizing power output from a solar system is desirableto increase efficiency.  In order to maximize power output from the solar panels, one needs to keep the panels aligned with the sun.  As such, a means of tracking the sun is required.  This is a far more cost effective solution than purchasing additional solar panels.  It has been estimated that the yield from solar panels can be increased by 30 to 60 percent by utilizing a tracking system instead of a stationary array .  This project develops an automatic tracking system which will keep the solar panels aligned with the sun in order to maximize efficiency.

Project on Pulse Oximeter

For patients at risk of respiratory failure, it is important to monitor the blood oxygen saturation of such individuals to ensure proper perfusion of blood in their system. Preferably this information should be received on a continuous basis. Both of these objectives can be reached via the non−invasive method of pulse oximetry. This is currently used in hospital/clinical settings, however uses wires which in effect bound an individual to an area. The purpose is to create a clinical diagnostic system which takes a few physiologically relevant signals and transmits them wirelessly to a base station.  This project specifically deals with the design of a wireless pulse oximeter for this system. By using the principle of differential light absorption and the assumption that the transmission of light through the arterial bed is influenced only by the relative concentrations of oxygenated and reduced hemoglobin and their  absorption coefficients at the two wavelengths, light intensity will decrease logarithmically according to Beer−Lambert’s law.The theory behind our device, hardware design and the experimental results of the system are presented.
