RADAR BULLET
ABSTRACT
Radar bullet is a special type of bullet the main use of radar bullet is to find landmines without setting foot into the ground .This consists of firing a special bullet into ground from a helicopter which could pinpoint buried landmines. Anti -personal mines claims seventy new victims every day. This weapon is particularly cruel on children whose bodies being smaller and closer to the blast are more likely to sustain serious injury. The severe disabilities and psychological trauma that follow ....etc

THE GURNEY FLAP
ABSTRACT
A Gurney Flap is the simplest trailing edge device which can be used as a high lift device for low speed applications like micro air vehicles, gliders, wind turbines etc. The Gurney Flap is named after American aero dynamist Dan Gurney who introduced it in the form of a vertical tab attached to the trailing edge of an ordinary aerofoil. This modification makes the flap capable of producing higher lift force at lower velocities.
This paper is based on the experimental analysi ....etc

Compound solid state switches such as GaAs MESFETs and PIN diodes are widely used in microwave and millimeter wave integrated circuits (MMICs) for telecommunications applications including signal routing, impedance matching networks, and adjustable gain amplifiers. However, these solid-state switches have a large insertion loss (typically 1 dB) in the on state and poor electrical isolation in the off state. The recent developments of micro-electro-mechanical systems (MEMS) have been continuously providing new and improved paradigms in the field ....etc

INTRODUCTION
1.1 INTRODUCTION:-
Patient monitor or multiparameter monitor or also referred to as physiological monitor is a clinical use electronic machine designed to display and minimally interpret, a person's vital signs. Some monitors can warn of pending fatal cardiac conditions before visible signs are noticeable to clinical staff .The parameters (or measurements) usually consist of Pulse Oximetry (measurement of the saturated percentage of Oxygen in the blood referred to as SPO2), ECG (electro-Cardiograph of ....etc

road accidents occur mainly due to violation of traffic rules and rash driving. this project deals with simple but efficient method to overcome this problem. It is possible to make the vehicles to follow traffic rules by controlling the speed of the vehicle electronically such that the driver will not be able to violate the traffic rules. Here the sensor is placed at a distance of 15m from the signal. While green light is ON, all the vehicles are allowed to ride (Circuit - Deactivate).When yellow light becomes ON (Circuit - Activate),the sensor ....etc

Wireless Sensor Networks

Technology Overview


The individual nodes that constitute a wireless sensor network are generally small in size and use power-efficient batteries to extend their operational longevity. Depending on its function, each node has a sensor board that facilitates the detection and measurement of heat, vibrations, air-pressure and magnetic fields (among other things). The motes developed at UC Berkeley are a typical example of such devices. Motes h ....etc

ABSTRACT
A surface micro machined capacitive switch has been designed and fabricated on a glass substrate. The switch is constructed of a thin metallic membrane crossing over an electroplated coplanar wave-guide transmission line. The electrostatic actuation is utilized as the switching mechanism. The actuation voltage is around 50V. The switch showed low insertion loss of 0.1 dB at 10 GHz and 0.4 dB at 25 dB, and isolation of 15dB at 20GHz. This device offers a potential application in tel ....etc
