Publication number: 20240078266Abstract: As an example, a system includes a hierarchical tag database that includes a plurality of tags arranged according to a hierarchical data schema for a number of tag hierarchies, and tags within each level of a respective tag hierarchy have a different specificity relative to each other level of the respective tag hierarchy. The data can also include profile tag data for a given user. The system can also include a processor configured to access the media and execute the instructions to expand each of the stored profile tags for the given user to provide an expanded profile tag data set for the given user, in which the expanded profile tag data set includes each of the assigned profile tags and each one or more higher-level tag in each associated tag hierarchy to which each of the assigned profile tags belongs.Type: ApplicationFiled: September 6, 2023Publication date: March 7, 2024Inventors: Jeffrey B.

Publication number: 20220160307Abstract: Systems and methods are described herein for estimating and filtering electrophysiological signals. In some examples, a noise filtering system can be employed to receive at least one electrophysiological signal. A signal segment extractor of the system can extract a signal segment of interest from the electrophysiological signal. The system employs a signal segment noise calculator to evaluate the extracted signal segment of interest to estimate a noise in the signal segment of interest. The estimated noise can be provided to a signal segment filter of the system to determine a surrogate noise estimate for at least one remaining signal segment of the electrophysiological signal for noise filtering the at least one remaining signal segment. The signal segment noise calculator can be configured to filter the signal segment of interest based on the estimated noise and the filtered signal segments can be combined to provide a filtered electrophysiological signal.Type: ApplicationFiled: June 9, 2021Publication date: May 26, 2022Inventors: QINGGUO ZENG, JEFFREY B. ADAIR, BRIAN P. GEORGE, QING LOU, TIMOTHY G. LASKE

Patent number: 10729345Abstract: For example, one or more non-transitory computer-readable media includes executable instructions to perform a method. The method includes defining a plurality of spatial regions distributed across a geometric surface. At least one wave front that propagates across the geometric surface is detected based on electrical data representing electrophysiological signals for each of a plurality of nodes distributed on the geometric surface over at least one time interval. An indication of conduction velocity of the wave front is determined for at least one spatial region of the plurality of spatial regions during the time interval based on a duration that the wave front resides within the at least one spatial region. Slow conduction activity is identified for the at least one spatial region based on comparing the indication of conduction velocity relative to a threshold. Conduction data is stored in memory to represent each slow conduction event.Type: GrantFiled: May 4, 2018Date of Patent: August 4, 2020Assignee: CARDIOINSIGHT TECHNOLOGIES, INC.Inventors: Qing Lou, Jeffrey B.
