Claim 19:
20. The blood pressure monitoring device of claim 19, wherein the control circuitry includes further logic that when executed causes the blood pressure monitoring device to perform further operations including:
computing a feature curve, corresponding to the fit provided by the machine learning model, representing the pulse amplitude of the arterial pulses included in a first tactile waveform over the first time period, where the arterial pulses of the first tactile waveform includes the basis arterial pulse; and
determining feature time instants based on at least one of a maximum pulse amplitude of the feature curve, a maximum slope of the feature curve, a minimum slope of the feature curve, or a foot of the feature curve, and
wherein the features include a pressure of the lowpass component at the feature time instants for each of the plurality of tactile waveforms.
