  • Publication number: 20240023826
    Abstract: An aerosol spirometer and a method of operating an aerosol spirometer. Comparison of lung function data that has been acquired by the aerosol spirometer to a known, idealized exhalation aerosol concentration profile of healthy lung operation may be used to fill in missing lung function data that arises out of resistance-based and compliance-based inhomogeneities in both aerosol penetration and aerosol deposition, where the inhomogeneities may be mathematically correlated to time constant data that in turn may be directly correlated to ventilation. This data, when added to the idealized exhalation aerosol concentration profile, produces a more complete data-informed exhalation aerosol concentration profile from which an inference may be made about possible lung dysfunction of an individual using the aerosol spirometer. A machine learning model may be trained on the lung function data to provide a predictive inference related to either an onset or worsening of the lung dysfunction.

    Abstract: The present systems and methods provide a mechanism to assess viewer behavior, features of stimuli, and the interaction between viewer behavior and stimuli. The systems and methods described herein for quantifying blink response and blink inhibition provide moment-by-moments measurements of viewer engagement by measuring what is or is not engaging enough to warrant viewers' inhibition of blinking. The present disclosure describes measures of visual scanning, eye movements, blink data, and blink timing data to derive a measure of how engaged a person is with what he or she is looking at. Blink-related data as a measure of viewer engagement provides a mechanism for determining the most engaging spatial and temporal aspects of a stimulus.

  • Publication number: 20240023869
    Abstract: A method includes receiving multiple electrophysiological (EP) signals acquired by multiple electrodes of a multi-electrode catheter that are in contact with tissue in a region of a cardiac chamber, and respective tissue locations at which the electrodes acquired the EP signals. The region is divided into two sections. Using the EP signals acquired by the electrodes, local activation times (LAT) are calculated for the respective tissue locations, and found are: a first section of the two sections having a smaller average LAT value, and a second section of the two sections having a higher average value. Determined are a first representative location in the first section, and a second representative location in the second section. A propagation vector is calculated between the first and second representative locations, that is indicative of propagation of an EP wave that has generated the EP signals. The propagation vector is presented to a user.
