Patent number: 11607143Abstract: 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: GrantFiled: April 6, 2020Date of Patent: March 21, 2023Assignee: VERILY LIFE SCIENCES LLCInventor: David He

Patent number: 11596317Abstract: Embodiments for protecting low-pressure blood pressure sensors in high-pressure fluid flow applications by equalizing pressure on both sides of a pressure sensor's diaphragm during high pressure are disclosed. A sensor protection device may include a pressure sensor assembly, a housing, and a plunger assembly.
