Author Affiliations +
ENSCO has been at the forefront in the development of a novel technology for human presence detection in vehicles, including automobiles, vans, trucks and semi-tractor trailers. This technology, by its very nature, is quite practical and less costly than other methods because it is based on a fundamental physiological characteristic common to all humans. Based on the ballistocardiogram force it measures the vehicle vibration produced by the individual's heart. The force produced by the heartbeats of humans will move vehicles, even large semi-tractor trailers, enough to be easily detectable by small seismic sensors. MicroSearch finds stowaways in a matter of seconds. No need to unload the vehicle, no need for manual searches.
