Claim 15:
16. A method comprising:
receiving, by a processor, a first detected electronic signal from a first detector, a second detected electronic signal from a second detector, and a third detected electronic signal from a third detector, each of the first, second, and third detectors being communicatively coupled to the processor and each of the first, second, and third detected electronic signals corresponding to a detected optical signal emanating from a pregnant mammal's abdomen and at least one of the first, second, and third detected electronic signals corresponding to a detected optical signal emanating from a pregnant mammal's abdomen also emanating from a fetus contained in the pregnant mammal's abdomen that is detected by the respective first, second, and third detectors and converted into the respective first, second, and third detected electronic signals;
performing, by the processor, independent component analysis on the first, second, and third detected electronic signals to generate a first separated signal, a second separated signal, and a third separated signal, the first separated signal, second separated signal, and third separated signal being contributed to the first, second, and third detected electronic signals by a first source, a second source, and a third source, respectively, wherein the third separated signal corresponds to a fetal photoplethysmogram signal;
analyzing, by the processor, the third separated signal to determine a hemoglobin oxygen saturation level of the the fetus contained within the pregnant mammal's abdomen; and
facilitating, by the processor, provision of an indication of the hemoglobin oxygen saturation level of the fetus to a user.
