Claim 8:
9. A method comprising:
receiving, by a processor, a plurality of detected electronic signals;
receiving, by the processor, a secondary signal;
filtering, by the processor, the received plurality of detected electronic signals using the received secondary signal;
performing, by the processor, independent component analysis on the plurality of filtered detected electronic signals to separate signals within the detected electronic signals that are contributed by different sources, each of the separated signals corresponding to a different source;
determining, by the processor, a separated signal that corresponds to light incident upon a fetus contained within a pregnant mammal's abdomen;
analyzing, by the processor, the separated signal that corresponds to light incident upon the fetus to determine a fetal hemoglobin oxygen saturation level of the fetus; and
facilitating, by the processor, provision of an indication of the fetal hemoglobin oxygen saturation level to a user.
