Passive method and system for contact and/or non-contact with or without intervening materials for detection and identification of the incidence, traverse and physiological condition of a living human at any instant

摘要

A low input current amplifier has a voltage spectral density curve to operate at 50 Hz or less and is connected to dielectric materials to receive a signal irrespective of ground reference. The amplifier outputs a first output. A multi-stage amplifier includes a stage connected in series with the low input current amplifier to amplify the first signal to distinguish the incidence, traverse and physiological condition of a living human. The resulting signal is then processed by an algorithm and displayed as human specific motion, heart rate and respiratory rate.
