Can you please show me a sample ppt on the " Life Detection System using L and S band Microwaes"?

Abstract

The "Life detection system : Based on L and S bands Microwaves" is a new revolutionary embedded system to detect human beings buried under earthquake rubble or debris. "Thousands of persons killed as a cause of earthquake". The above words aren’t the headlines of the newspaper but daily news everyone come across whenever we go through a newspaper or watching over a TV news. With the meteoric embedded systems along with microprocessor preventing deaths and providing safe guided measures. By advent of this system the world death rate may decrease to greater extent as large percentage of death occur due to earthquake. The advantages of microwave signals are fully utilized in this system.The L and S band microwaves are used here to detect the living body.

Why Microwave Based Life Detection?

A new sensitive microwave life-detection system which can be used to locate human subjects buried under earthquake rubble or hidden behind various barriers has been constructed. By advent of this system the world death rate may decrease to greater extent as large percentage of death occur due to earthquake. This system operating at 1150 MHz or 450 MHz can detect the breathing and heartbeat signals of human subjects through an earthquake rubble or a construction barrier of about 10-ft thickness. Previous methods for searching and rescuing human victims buried under earthquake rubble or collapsed building debris were the utilization of dogs, or seismic or optical devices. These devices are not effective if the rubble or debris covering the human victims is thicker than a few feet, especially for the case when the victims are completely trapped or too weak to respond to the signal sent by the rescuers.
