Patent number: 11957451Abstract: Breath sensor calibration methods and apparatus are described herein where a breath sensor device may generally comprise a sampling unit having a housing configured to receive a sample breath from a user and a sensor positioned within the housing. A processor in electrical communication with the sensor may be configured to determine a dissipation time when the sensor is exposed to a near-constant concentration level of CO detected from the breath sample down to an ambient level of CO detected. The processor may also be configured to calculate a time constant based on the dissipation time and a reduction from the near-constant concentration level to the ambient level. Furthermore, the processor may also be configured to apply the time constant to a transient response of the sensor to account for drift in calibrating the sensor.Type: GrantFiled: December 23, 2020Date of Patent: April 16, 2024Assignee: Pivot Health Technologies Inc.Inventors: Allen Jameson, Brian Herold, Eric Tridas

Patent number: 11931172Abstract: A circadian health system (CHS) provides for improving the health of Alzheimer's patients and other persons by controlling their exposure to circadian lighting. Circadian sensor devices (CSDs) are distributed in a living space, e.g., at about eye-level positions on respective walls of room. Each CSD includes a spectral sensor for measuring the intensity of light at various wavelength bands. Captured spectra can be compared to circadian light signatures so that the sources of circadian light can be identified. The identifications then allow predetermined high-resolution, e.g., 5 nm, spectra in the circadian wavelengths of 450-500 nm to be determined. The spectra can then be used to control circadian lighting to provide prescribed doses of circadian stimulus.Type: GrantFiled: January 12, 2021Date of Patent: March 19, 2024Assignee: Blue Iris Labs, Inc.Inventor: Erik Russell Page
