DETERMINING REAL-TIME SLEEP STATES USING MACHINE LEARNING TECHNIQUES

Cardiac data defining at least inter-beat interval (IBI) sequences is received. Tagging data that defines tags of sleep-states for the IBI sequences is received. A sleep-state classifier is generated using the cardiac data and the tagging data, the generating may include: extracting the IBI sequences from the cardiac data; training a convolutional neural network (CNN) using as input the cardiac data and the tagging data to generate intermediate data; and iteratively training a recurrent neural network (RNN) configured to produce state data as output, the iterative training of the RNN using i) the intermediate data as an initial input and ii) the intermediate data and a previous state data as subsequent input.

Surgical system for detecting gradual changes in perfusion
11517183 · 2022-12-06 · ·

The present disclosure is directed to an augmented reality surgical system. The system includes an endoscope that captures an image of the region of interest of a patient and an ECG device that records an ECG of the patient. A controller receives the image and applies at least one image processing filter to the image. The image processing filter includes a decomposition filter that decomposes the image into frequency bands. A temporal filter is applied to the frequency bands to generate temporally filtered bands. An adder adds each band frequency band to a corresponding temporally filtered band to generate augmented bands. A reconstruction filter generates an augmented image by collapsing the augmented bands. The controller also receives the ECG and processes the augmented image with the ECG to generate an ECG filtered augmented image. A display displays the ECG filtered augmented image to a user.

Mean TSI feature based determination method and system

The present invention relates to a method to provide a mean temporal spatial isochrone (TSI) feature relating to an ECG feature (wave form) of interest, such as the activation of the heart from a single point (QRS), relative to the heart in a torso while using an ECG measurement from an ECG recording device. The method includes: receiving ECG measuring data from the ECG recording device; determining vector cardiogram (VCG) data; receiving a model of the heart, preferably with torso, as an input, preferably based on a request including request parameters; determining mean TSI data values representing the TSI feature relating to an electrophysiological phase representing the ECG feature, the mean TSI providing a location within the heart representing the mean location of the ECG feature at the corresponding time; positioning the mean TSI feature and preferably the vector cardiogram data points in the model of the heart and/or torso at an initial position; and rendering the model of the heart, preferably with torso, with the mean TSI feature, preferably with VCG data related to the TSI, for displaying on a display screen for interpretation of the displayed rendering.
