  • PULSE OXIMETRY DEVICE AND METHOD
    Publication number: 20220304590
    Abstract: System and apparatus for pulse oximetry. Systems, methods, and devices are presented for placement of the hardware on a body part where detracting signals are strong. In one example, detracting signals include signals from respiration. In various examples, the body part the oximeter is placed on is a wrist, chest, or arm. A computationally efficient pipeline is presented that allows for reliable and robust SpO2 estimation.

  • Optical measurement of displacement
    Patent number: 10932072
    Abstract: Systems and methods for optically measuring displacement of an element include an emitter for emitting an optical signal, a first detector for detecting reflections of the optical signal from the element, a second detector for detecting reflections of the optical signal from a raised cover structure, a processor for receiving the detected reflections from the first and second detectors and removing distortions in the detected reflections from the first detector using the detected reflections from the second detector.

  • MATERIAL CHARACTERISTIC SIGNAL DETECTION METHOD AND APPARATUS
    Publication number: 20190150839
    Abstract: Device for detecting characteristic signals of tissues and materials and methods for calculating thereof. Apparatus and methods for detecting the presence of tissue (skin) in pulse oximeter are disclosed. Specifically, analysis using optical techniques are used to identify characteristic signals of different compositions of matter. The present application discloses using a plurality of photodetectors at different distances from a source to measure light scattering through a variety of materials, and more specifically, to detect the presence of tissue.
