  • Patent number: 9907510
    Abstract: To improve convenience in a wearable electronic apparatus that measures biological information. An electronic apparatus includes a sensor mechanism, a main body, and a retaining mechanism. The sensor mechanism acquires biological information of a user. The main body supports the sensor mechanism in a movable manner in an upper/lower direction. The retaining mechanism changes the sensor mechanism and the user's body between an unpress state and a press state by moving the sensor mechanism at the main body. With the electronic apparatus, a displacement of the sensor mechanism from the body is prevented and the maintenance of a contact condition is secured, an optical measurement becomes possible; therefore, it is thereby possible to improve convenience for a user without adjusting a position, etc.

  • Patent number: 9795296
    Abstract: Embodiments of the invention provide a system, apparatus and methods for measurement of biometric data of a diver. In many embodiments, the system includes a mouthpiece having a sensor device comprising a light emitter and detector configured to emit and detect light at a wavelength having an absorbance correlated with a level of a blood gas saturation e.g., oxygen, nitrogen, CO2. The emitter is positioned to emit light onto oral tissue of the diver and the detector positioned to detect light which is received from the oral tissue either by transmittance of light through the oral tissue or by reflection of light from the tissue. The target oral tissue can include one or both of gum or buccal tissue. Such embodiments allow data to be collected without having to wear additional sensors or measurement devices and allow for measurement of blood gas levels as the diver breaths through their mouthpiece.

  • Patent number: 9757058
    Abstract: Light beams emitted from one or more light sources may be directed into an abdomen of a pregnant mammal toward a fetus contained therein. Some of the light may be reflected by the pregnant woman and fetus and received at a detector over a first time. A photo detector into an electronic reflected signal, which may be communicated to a computer, may then convert the received light. The electronic reflected signal may then be processed and/or analyzed to isolate a portion of the electronic reflected signal reflected from the fetus. The isolated portion of the electronic reflected signal reflected from the fetus may then 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 an operator by way of, for example, a computer display.
