  • Patent number: 11660006
    Abstract: A wearable device includes a housing with a window and an electronic module supported by the housing. The electronic module includes a photoplethysmography sensor, a motion sensor, and a signal processor that processes signals from the motion sensor and signals from the photoplethysmography sensor. The signal processor is configured to remove frequency bands from the photoplethysmography sensor signals that are outside of a range of interest using a band-pass filter to produce pre-conditioned signals, and to further process the pre-conditioned signals using the motion sensor signals to reduce motion artifacts from footsteps during subject running. The device includes non-air light transmissive material in optical communication with the photoplethysmography sensor and the window that serves as a light guide for the photoplethysmography sensor. The window optically exposes the photoplethysmography sensor to a body of a subject wearing the device via the non-air light transmissive material.

  • Patent number: 11313817
    Abstract: A variety of application can use nuclear magnetic resonance as an investigative tool. Nuclear magnetic resonance measurements can be conducted using a nuclear magnetic resonance microscope. An example nuclear magnetic resonance microscope can comprise a film embedded in a coverslip, where the film is doped with reactive centers that undergo stable fluorescence when illuminated by electromagnetic radiation having a wavelength within a range of wavelengths and a magnetic field generator to provide a magnetic field for nuclear magnetic resonance measurement of analytes when disposed proximal to the film. Microwave striplines on the coverslip can be arranged to generate microwave fields to irradiate the analytes for the nuclear magnetic resonance measurement. Control of the microwave signals on the microwave striplines can be used for dynamic nuclear polarization in the nuclear magnetic resonance measurement of analytes.

  • Patent number: 11278221
    Abstract: Physiologic sensors and methods of application are described. These sensors function by detecting recently discovered variations in the spectral optical density at two or more wavelengths of light diffused through the skin. These variations in spectral optical density have been found to consistently and uniquely relate to changes in the availability of oxygen in the skin tissue, relative to the skin tissue's current need for oxygen, which we have termed Physiology Index (PI). Current use of blood gas analysis and pulse oximetry provides physiologic insight only to blood oxygen content and cannot detect the status of energy conversion metabolism at the tissue level. By contrast, the PI signal uniquely portrays when the skin tissue is receiving ‘less than enough oxygen,’ just the right amount of oxygen,? or ‘more than enough oxygen’ to enable aerobic energy conversion metabolism.
