Patent number: 11730391Abstract: A breath analyte device includes a breath volume in fluid communication with a sampling volume. The device also includes a sampling sensor configured to generate a breath signal that varies in response to changes in gas pressure (e.g., sound waves) in the breath volume and one or more analyte sensors configured to generate one or more analyte signals that vary in response to a concentration of one or more target analytes present in the sampling volume. A control unit is configured to determine a time at which to measure the concentration of target analytes in the sampling volume based on the breath signal and measure the concentration of the target analytes based on the analyte signals at the determined time. The device may also include a pump configured to motivate gas from the breath volume into the sampling volume prior to measuring the concentration of the target analytes.Type: GrantFiled: June 28, 2022Date of Patent: August 22, 2023Assignee: Readout, Inc.Inventors: Timothy V.
