Publication number: 20230270377Abstract: Approaches to determining a sleep fitness score for a user are provided, such as may be based upon monitored breathing disturbances of a user. The system receives user state data generated over a time period by a combination of sensors provided via a wearable tracker associated with the user. A system can use this information to calculate a sleep fitness score, breathing disturbance score, or other such value. The system can classify every minute within the time period as either normal or atypical, for example, and may provide such information for presentation to the user.Type: ApplicationFiled: May 5, 2023Publication date: August 31, 2023Inventors: Suraj Gowda, Conor Joseph Heneghan, Shelten Gee Jao Yuen, Anjian Wu, Daniel Joel Freschl, Peter W. Richards, Chris H. Sarantos, Jonathan Wonwook Kim

Patent number: 10765409Abstract: Health information for a woman can be used to predict timing of events related to the woman's menstrual cycle. If available, historical cycle information for a woman can be used to predict upcoming cycle events, such as the start and stop of menstruation. To improve the accuracy of those predictions, one or more health metrics are monitored for the woman that can be correlated with the menstrual cycle. These can include, for example, the resting heart rate (RHR), blood oxygen concentration (SpO2) level, and hemoglobin concentration, among other such options. The metrics are monitored over time to determine patterns that can be correlated with menstrual cycle. This information can then be used to update the predictive model, as well as to update individual event predictions. Information about the predictions, and updates to the predictions, can be surfaced accordingly.Type: GrantFiled: June 14, 2019Date of Patent: September 8, 2020Assignee: FITBIT, INC.Inventors: Belen Lafon, Chris H.
