controller) ABSTRACT: A new revolutionary microwave life detection system. Which is used to locate human beings buried (or) trapped under earthquake rubble has been designed. This system operating at certain frequency can remotely detect the breathing and heart beat signals of human beings buried under earthquake rubble. By proper processing of these signals‚ the status of the person under trap can be easily judged. The entire process takes place within a few

An electrically driven vibrator was used to maintain a constant frequency. The string was not changed during the trials and thus‚ the mass per unit length‚ µ‚ remained constant. The frequency of the stroboscope was decreased from 179.96 Hz to 108 Hz in order to obtain the highest frequency at which the vibrator was gripped in position. The correct frequency of the vibration was 59.03 Hz. It was observed that the wavelength varies linearly with the square root

country while most of the power consumption states lie in the western part of the country. There was absence evacuation mechanism of power from one region to another region. As result of it different regions were used to operate at different frequencies. Also frequencies used to widely vary across the day putting network security at stake. It was in October 1991 the Eastern and Northeastern grid was synchronized. It took a long 12 year period‚ March 2003‚ to synchronize the coal rich power producing states

set of frequencies. In normal basic telephone service‚ a pair of wires is used for communication. But in case of mobile/wireless communications‚ airwaves are used instead of wires. These spectrum/airwaves are licensed by the Government. It is allocated in Mega Hertz (MHz) in telecom licenses. 4.2 MHz is given as start-up spectrum‚ which is topped up by 1.8 MHz to make it 6 MHz (4.2 + 1.8 MHz)‚ and so on. 2) Why spectrum is called a scarce national resource? Worldwide different frequencies are used

receiver. An eavesdropper may have difficulty intercepting a transmission in real time if the pseudorandom sequence is not known. Spread-spectrum transmissions can share a frequency band with many types of conventional transmissions with minimal interference. The spread-spectrum signals add minimal noise to the narrow-frequency communications‚ and vice versa. As a result‚ bandwidth can be used more efficiently.
