ABSTRACT:
A method and apparatus are provided for measuring a weak physiological signal in the presence of stronger signals. The method and apparatus utilize motion sensing devices placed on or about the patient to obtain a motion data set from each motion sensing device describing the aggregate detected motion. The data sets are synchronized and then used to solve a set of simultaneous equations which allows for the separation of the various motion components which may include such components of interest as fetal heart motion.
