  • Publication number: 20200077929
    Abstract: During childbirth process, trauma to an infant can readily arise, ultimately resulting in fetal hypoxia, academia, and brain damage. Such unfavorable conditions can be prevented by measuring the fetus' blood-oxygen level and heart rate. Without a fetal pulse oximeters, blood oxygen level cannot be monitored non-invasively reliably, which reduces the chance for birth complications to be recognized in time. A noninvasive system to implement such goals and maximize the potential welfare of the fetus may include devices to measure oxygen saturation of hemoglobin (SpO2) that have been available for at least 50 years. Such a device may be an oxy probe that uses a trans-reflective method of SpO2 measurement where oxygen saturation data can be transmitted through wire, fiber optics, and or using a radio frequency link, fetal monitor data can be analyzed, compared to existing data base, and or transmitted via radio waves or internet.

  • Publication number: 20040082842
    Abstract: During childbirth, trauma to the infant can readily arise, ultimately resulting in fetal hypoxia, academia, and brain damage. Such unfavorable conditions can be best ascertained by real-time monitoring of the fetus' blood-oxygen level, heart rate monitoring, EKG and EEG waveforms. This invention describes a system of monitoring devices to implement such goals and maximize the potential welfare of the fetus. It furthermore allows the formation of a reference database that can correlate intrapartum events from prior births. The embodiments utilize a small-diameter sensor inserted into the birth canal through a tubular insertion rod. Through wire, fiber optics, and or using a radio frequency link, fetal monitor data can be analyzed, compared to existing data base, and or transmitted via internet. This patent details various apparatuses that allow important life-sign parameters of a fetus to be continuously monitored.

  • Patent number: 6122042
    Abstract: An apparatus for photometric analysis and/or identification of properties of a material object comprises a collection of light sources having substantially distinct wavelength envelopes and activated in a rapid sequence of distinct combinations. The apparatus comprises a collection of spatially distributed light detectors which detect radiation from the object and produce detected signals. A signal processor for controlling the light sources and analyzing the detected signals synchronizes the detected signals with the activation of the sequence of distinct combinations of the light sources to produce associated combinations of detected signals which are then analyzed to determine a physical property of the object and/or compared for similarity to previously detected signals from known objects. The photometric data may be combined and correlated with other measured data to enhance identification.

  • Patent number: 4160308
    Abstract: An improved optically coupled isolator uses a glass layer in combination with layers of junction coat material between the emitter and detector to provide greater electrical isolation while preventing potential ionic contamination in the glass from reaching the detector and causing a deterioration in its operating characteristics. The isolator is assembled using standard semiconductor processing techniques so that the cost of manufacture is not substantially increased.
