Harold N Arneson, Louis J Heitlinger: Physiological waveform detector. General Electric Company, Ralph G Hohenfeldt, Fred Wiviott, February 24, 1976: US03939824 (66 worldwide citation)

A physiological waveform detector such as for cardiac R-wave and blood pressure uses a comparator to compare the derivative of the waveform signal with a reference signal representing some percentage of the magnitude of the derivative of the waveform. If the derivative is of sufficient magnitude to ...
