by using smart sensors (which following pricipal of Piezo electricity) we can make electricity here in this project we will place smart sensors in the high dense roads (such as traffic jam places in some cities) as this sensors convert static energy of vehicles into power and this can be used for lightning the streets and so on.and similarly by using smartsensors we can extend its application for vehicle tracking, navigation and so on.Using the same smart sensors we need to place those by making 8slots in the wheel of goods train (since indianr ....etc

Instrumentation that converts the signal to engineering units must know a few things about what parameters to expect from the sensor. That's because full-scale range, sensitivity, connection schemes, and other factors all vary greatly from one kind of sensor to another. The end result is that it takes some effort to match up sensors with monitoring electronics. This configuration process may be no big deal when there are only a few sensors involved. But it can be problematic when gangs of sensors get wired into multichannel measurement systems. ....etc

A guidance system for helping the blind find the way is described. Means to generate modulated signals of different frequencies is there and also a means to amplify and transmit these signals through conductors along the path of the journey. A cane recieves the signals through oscillating means responsive to each signal. It also comprises an amplifier to amplify the signals so that it can be detacted by many persons carrying such recievers along the path.

An oscillator, amplifier and a pulse generator makes up the reciever stick. This syst ....etc

Landmines and unexploded ordnance


INTRODUCTION

Landmines and unexploded ordnance (UXO) are a legacy of war, insurrection, and guerilla activity. Landmines kill and maim approximately 26,000 people annually. In Cambodia, whole areas of arable land cannot be farmed due to the threat of landmines. United Nations relief operations are made more difficult and dangerous due to the mining of roads. Current demining techniques are heavily reliant on metal detectors and prodders.

LANDMINES
Department of Mechanical Engineering
RAJIV GANDHI INSTITUTE OF TECHNOLOGY



INTRODUCTION
One of the most deadly legacies of the 20th century is the use of landmines in warfare. Anti-personnel landmines continue to have tragic, unintended consequences years after a battle and even the entire war has ended. As time passes, the location of landmines is often forgotten, even by those who planted them. These mines continue to be functional for many decades, cau ....etc

POTENTIAL OF PIEZO ELECTRIC ECOFLOOR FOR GENERATION OF ELECTRIC POWER

The need to generate electricity is the demand for today s life because of the fact that even if the planet doubles the amount of solar and wind power available, there would still be a shortage of clean electricity. Comparison of different forms of commercial power generation by use of the fuel cycle methods developed in European studies shows that the health burdens are extreme in areas where power stations (based on coal, Ignite, and oi ....etc
