Kyle P. Nadeau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multiple source-detector pair photoplethysmography (PPG) sensor
    Patent number: 11779231
    Abstract: Systems, devices, and methods for tracking one or more physiological metrics (e.g., heart rate, blood oxygen saturation, and the like) of a user are described. For example, one or more light sources and one or more light detectors may be positioned on a wearable device such that light can be emitted towards the user's skin and further such that light reflected back to the wearable device can be measured and used to generate values for the one or more physiological metrics.
    Type: Grant
    Filed: July 2, 2021
    Date of Patent: October 10, 2023
    Assignee: FITBIT, INC.
    Inventors: Kyle P. Nadeau, Chris H. Sarantos, Kevin Pu Weekly, Javier L. Prieto, Peter W. Richards, Paul Francis Stetson, Aniket Sanjay Deshpande
  • Light field management in an optical biological parameter sensor
    Patent number: 11206989
    Abstract: Structures and techniques are provided for shaping or steering a light field for an optical biological parameter sensor such that the light is partially or wholly collimated and enters a person's skin at an oblique angle to the person's skin such that the light has a direction component oriented towards or away from a photodetector of the optical biological parameter sensor.
