Abstract: A system and/or device for transabdominal fetal oximetry and/or fetal pulse oximetry and/or uterine tone determination may include one or more articulating, adjustable, and/or selectable components such as a light source and/or a photodetector. In some embodiments, the positioning of a light source and/or detector may be adjustable. The articulation and/or adjustment of position of the light source and/or photodetector may be in any plane (X, Y, and/or Z) and, in some instances, may be responsive to a fetal position within a maternal abdomen. Light detected by the detectors may be used to determine a fetal hemoglobin oxygen saturation level and/or a muscular state (e.g., contracted or relaxed) of the pregnant mammal's uterus.

Abstract: Optical, geometric, and/or physiological characteristics of a mammal and/or a pregnant mammal's abdomen may be used to determine a personalized calibration formula for the respective mammal or pregnant mammal's abdomen. This personalized calibration formula may be used to analyze or evaluate light transmission data corresponding to an optical signal that is detected by a photodetector and converted into the light transmission data to determine an oximetry value for the mammal, pregnant mammal, and/or fetus. The optical signal may be a composite of light that was incident on the mammal or pregnant mammal's abdomen her fetus. On some occasions, an image of the mammal's tissue and/or the pregnant mammal's abdomen may be received and used to generate a tissue model of the respective mammal's tissue or maternal abdomen. The tissue model may be used to generate, or adjust, the personalized calibration formula.

Abstract: A physiological indicator for a pregnant mammal and/or her fetus may be used to augment and/or personalize a fetal oximetry model to the pregnant mammal, the fetus, and/or the pregnant mammal/fetus pair. Light transmission data that corresponds to and/or represents a composite of light that passes through the pregnant mammal's abdomen and the fetus may be received and input into the augmented fetal in vivo fetal oximetry model. An output from the augmented fetal in vivo fetal oximetry model that includes an indication of an oximetry value and/or wellness for the fetus may be generated and/or received.

Abstract: Fetal oximetry information may be determined using a plurality of different types of measurement systems and/or calculation techniques. In some instances, a first measurement system may be used to interrogate maternal abdominal tissue to determine one or more characteristics thereof. Then, a second measurement system may be used to interrogate the pregnant mammal's abdominal tissue as well as fetal tissue and the characteristics of the maternal tissue determined using measurements of the first system may be used to process the measurements obtained using the second system to, for example, increase the accuracy of the processing of the measurements from the second system.

Abstract: A plurality of sets of simulated optical inputs that is simulated to travel through an animal model of tissue, thereby generating simulated light transmission data, and corresponding oximetry vales may be used to train a simulated fetal oximetry model to predict, or calculate, oximetry values for subsequently received sets of simulated light transmission data. The simulated fetal oximetry model may be adapted to train an in vivo fetal oximetry model that may be configured to predict, or calculate, fetal oximetry values for subsequently received sets of light transmission data received from an in vivo study of a pregnant mammal and her fetus.

Abstract: Independent component analysis may be performed on a plurality of detected electronic signals to separate signals within the detected electronic signals that are contributed by different sources. Each of the plurality of detected electronic signals may be received from a separate detector and may correspond to a detected optical signal emanating from a pregnant mammal's abdomen and a fetus contained therein. The detected optical signals may correspond to light that is projected into the pregnant mammal's abdomen from a light source. The separated signals may be analyzed to determine a separated signal that corresponds to light incident upon the fetus, which may be analyzed to determine a fetal hemoglobin oxygen saturation level of the fetus. An indication of the fetal hemoglobin oxygen saturation level may then be provided to the user.

Abstract: One or more properties of a pregnant mammal and/or fetus may be used to generate a personalized calibration equation, curve, or formula that may be used to process light transmission data received from a near infrared spectroscopy system used to investigate the pregnant mammal's abdomen. Light detected by a photodetector of and/or associated with the near infrared spectroscopy system may be analyzed using the personalized calibration curve to determine an oxygenation level of the fetus and/or determine a probability of whether, or not, the fetus may be in distress.

Abstract: Fetal tissue oxygenation may be performed transabdominally by, for example, receiving a plurality of detected electronic signals that correspond to light emitted from a pregnant mammal's abdomen and a fetus contained therein that has been detected by the detector and converted into the detected electronic signal. An indication of a depth of the fetus within the pregnant mammal's abdomen may be received and a portion of the detected electronic signals that correspond to light that was incident upon the fetus may be isolated responsively to the indication of the depth of the fetus using, for example, time of flight of photons that correspond to the detected electronic signals. A fetal tissue oxygen saturation level may then be determined using the isolated portion of the detected electronic signals that correspond to light that was incident upon the fetus.

Abstract: The invention features a headset, and systems including the headset, equipped with electrical sensors. The headset is suitable for use by a child and suitable for use in a gaming system, e.g., to train attention.
