Real time audification of neonatal electroencephalogram (EEG) signals

The present invention discloses a method and system of providing a real time audification of neonatal EEG signals. The method comprises the steps of: receiving preprocessed neonatal EEG signals; changing a characteristic of the preprocessed signals in a phase vocoder; resampling the output signals from the vocoder to a predetermined audio frequency range; converting the resampled signals into stereo signals; and selecting a plurality of channels from the stereo signals as the output audio signals.

Systems and Methods for Generating Synthetic Cardio-Respiratory Signals
20200163627 · 2020-05-28 ·

Devices and methods for generating synthetic cardio-respiratory signals from one or more ballistocardiogram (BCG) sensors. A method for determining item specific parameters includes obtaining ballistocardiogram (BCG) data from one or more sensors, where the one or more sensors capture BCG data for one or more subjects in relation to a substrate. For each subject, the captured BCG data is pre-processed to obtain cardio-respiratory BCG data. The cardio-respiratory BCG data is sub-sampled to generate the cardio-respiratory BCG data at a cardio-respiratory sampling rate conducive to cardio-respiratory signal generation. The sub-sampled cardio-respiratory BCG data is cardio-respiratory processed to generate a cardio-respiratory parameter set. A synthetic cardio-respiratory signal is generated from at least the cardio-respiratory parameter set and a cardio-respiratory event morphology template. A condition of the subject is determined based on the synthetic cardio-respiratory signal.
