Abstract :
The design and capabilities of a noninvasive system to record the superficial temporal artery (STA) pulse pressure of pilots during diving scenarios are described. The piezoelectric pulse pressure monitoring System (P3) records the best waveform from an array of piezoelectric benders in contact with the skin above the STA during 0 Gz acceleration and then continuously monitors it during +Gz acceleration for determination of G-LOC (positive Gz-induced loss of consciousness) conditions. Results indicate that the P3 may be used in a cockpit environment and could be the controller in an aircraft autorecovery
