Systems and methods for noninvasive spectral-spatiotemporal imaging of cardiac electrical activity

A system and method for non-invasively generating a report of cardiac electrical activities of a subject includes determining, using cardiac electrical activation information, equivalent current densities (ECDs). The ECDs are assembled into time-course ECD information and a spectrum of the time-course ECD information is analyzed to determine peaks for spectral characteristics of atrial fibrillation (AF). The spectral characteristics of AF are correlated with potential electrical sources of the AF and a report is generated indicating the potential electrical sources of the AF spatially registered with the medical imaging data.

Physiologic signal analysis using multiple frequency bands
10820820 · 2020-11-03 · ·

Described herein are implantable systems and devices, and methods for use therewith, that distinguish between different signal components of interest in sensed physiologic signals with high sensitivity and specificity. Such a method can include obtaining a sensed signal using an IMD and using a plurality of different filters that are parallel to one another to simultaneously filter the sensed signal, and/or copies thereof, to produce different filtered signals. Where each filter has a respective passband that does not substantially overlap with the passband(s) of the other filter(s), each of the different filtered signals will be indicative of different frequency content of the sensed signal. Additionally, amplitudes of temporally aligned peaks in at least two of the different filtered signals can be detected, and one or more peaks of the sensed signal can be classified based on the detected amplitudes of the temporally aligned peaks in the different filtered signals.

MODIFICATION OF BEHAVIOR OR PHYSICAL CHARACTERISTICS THROUGH VISUAL STIMULATION
20200337577 · 2020-10-29 ·

A system and a process are provided for evaluating subliminal pixel patterns and identifying trigger patterns, which are pixel patterns that trigger a response in subjects exposed to the pattern. Each pixel pattern is embedded in a digital video or a digital still image. Pixel patterns that are found to induce reactions in subjects are identified as trigger patterns and are flagged for re-testing. Re-tested trigger patterns that repeatably induce reactions are identified as positive trigger patterns and are studied further. Variations are made to a positive trigger pattern to determine whether small changes can affect how a subject responds when exposed to that positive trigger pattern. A positive trigger pattern is evaluated to determine whether it can induce an emotional, a physical, and/or a behavioral change in the subjects and, if so, the positive trigger pattern is applied to a real-world situation.

The computer system further comprises a segment comparator for determining if the segment of maximum fatigue is consistent with the assumed maximum fatigue segment, and a limit setter for setting the segment of maximum fatigue as a revised assumed maximum fatigue segment, if the segment of maximum fatigue is inconsistent with the assumed maximum fatigue segment, and supplying the EEG classifier trainer with the revised assumed maximum fatigue segment. The computer system further comprises a model output module for setting the EEG classifier as the EEG model for discriminating between alert and fatigue states in segments of EEG data, if the segment of maximum fatigue is consistent with the assumed maximum fatigue segment.
