Patent number: 11666703Abstract: A biosensor includes an optical circuit that obtains a plurality of photoplethysmography (PPG) signals from light at different wavelengths that is reflected from or transmitted through tissue of a user. A processing circuit determines a measurement value for a nitric oxide (NO) level in blood flow using first and second PPG signals and determines an insulin response from caloric intake using the measurement value for the NO level in blood flow. The first PPG signal is obtained from light at a wavelength having a high absorption coefficient for NO in blood flow and the second PPG signal is obtained from light at a second wavelength having a low absorption coefficient for NO in blood flow. The processing circuit also determines one or more phases of digestion using at least one or more of the plurality of PPG signals.Type: GrantFiled: August 17, 2020Date of Patent: June 6, 2023Assignee: TRILINEAR BIOVENTURES, LLCInventors: Robert Steven Newberry, Matthew Rodencal

Patent number: 10672298Abstract: A blood flow simulator generates a compression and expansion in a test fluid that emulates the pressure waveform created by a heartbeat in blood flow. The blood flow simulator stores a plurality of pressure waveform files that include actual data recorded from a heartbeat, arterial pressure waveform, or venous pressure waveform. One or more of the pressure waveform files may be selected and the pressure waveform file is used by the blood flow simulator 100 to generate a pressure waveform in pressurized fluid. The pressurized fluid flows through a test site, such as a surrogate body part or an optical window or other component with material having similar properties to human tissue. Various target substances may also be added to the fluid in known concentrations for testing and configuration of medical devices at the test site.Type: GrantFiled: September 18, 2017Date of Patent: June 2, 2020Assignee: SANMINA CORPORATIONInventors: Robert Newberry, Matthew Rodencal, Nate Roth
