Detecting land mines is the major
problem in combing areas where terrorists place land mines to kill the public as
well as soldiers in reaching them. There are many technologies developed so
far, but here we talk about latest one to detect the land mines before stepping
on it. This technology is under design by LEMUR STUDIO design organization
located at Columbia. This technology needs two devices, one fitted on shoes for
prior detection and another on hand to view the exact location of land mine
through GPS.
The key elements in the two devices
are coil, microprocessor, radio transmitter, hand held device, GPS. Coil in the
shoe is to emit the electromagnetic waves, microprocessor is used to detect the
changes in the electromagnetic waves, radio transmitter is used to send the
changes to the hand held device and the GPS is for locating the object in terms
of longitude, latitude and elevation.
HOW IT WORKS???
The coil in the shoe is emitting
electromagnetic waves(these are released when electrons pass through conductor)
continuously, when these get disturbed by the land mine, the signals at that
moment are captured by the microprocessor which are sent to hand held device
through GPS. The alarm present in the hand held device gets on and position of
the land mine can be detected before stepping on it.
