Searching for survivors after a disaster
is always a race against time. The Life Detector can
help fire/search and rescue services to pinpoint persons
who can still indicate that they are alive by means
of movements, knocking or calling. The Life Detector
is capable of detecting these signs of life by using
special sensors designed to pick up the extremely small
vibrations transmitted in solid or gaseous media.
Experience has shown that very frequently
victims trapped in a building collapse can hear their
rescuers, but cannot be heard themselves outside of
the rubble pile. Layers of solid concrete or rubble
can block any airborne sounds from escaping. However,
if the victims can tap, scratch, or move, the collapsed
structure carries these sounds effectively. These sounds
are not heard by the human ear, but they can be picked
up by electronic listening devices. These devices employ
Sensors which can convert the vibrations into visible
and/or audible signals.
The Delsar Life Detector is a seismic/acoustic
listening device designed specifically to detect and
locate trapped, live victims in collapsed structures
caused by earthquakes, explosions, landslides, mine
disasters, or construction cave-ins.
