Publication number: 20200323450Abstract: Various examples are described for detecting heart rate and respiratory rate by using measurements of light applied to skin through an article. For example, a sensor application obtains a set of measurements of light. The application compensates for a contribution of the article based on one or more known optical properties of the article. The sensor application further determines, from the set of measurements of light, a periodic change in amplitude. The sensor application identifies the periodic change in amplitude as a heart rate having an identical periodicity. The sensor application identifies a respiratory rate as equal to the rate of change of the heart rate.Type: ApplicationFiled: April 6, 2020Publication date: October 15, 2020Applicant: Verily Life Sciences LLCInventor: David He

Publication number: 20190340515Abstract: Various examples are described for using a movement sensor to detecting an activity of an infant. In an example, an activity classification system includes a sensor configured to measure the activity of an infant and an external monitor. The monitor receives, from a sensor, a time series of data comprising an inertial measurement for each a time period. The monitor determines, from the time series and by using a predictive model, an activity from a list of identified activities. Examples of identified activities are deep sleep, light sleep, sitting, awake, nursing, or bottle feeding.Type: ApplicationFiled: April 12, 2019Publication date: November 7, 2019Applicants: Verily Life Sciences LLC, The Procter & Gamble CompanyInventors: Anupam Pathak, David He, Marty Gardner, Blanca Arizti

Publication number: 20180205627Abstract: Techniques are provided for automatically accounting and apportioning of observed service execution times. In an embodiment, the computers determine a total amount of time to process a request. The computers determine which services are called in order to process the request. The called services include a first service and a second service. The computers determine a first amount of time that the first service spends in response to processing the request and a second amount of time that the second service spends in response to processing the request. The computers calculate a first percentage for the first service based on the first amount of time and the total amount of time and a second percentage for the second service based on the second amount of time and the total amount of time.Type: ApplicationFiled: January 4, 2016Publication date: July 19, 2018Inventors: Toon Sripatanaskul, Thomas Goetze, Ritesh Maheshwari, David He, Ruixuan Hou
