Abstract: The present description relates generally to methods and systems for detecting cardiovascular conditions using a foundation model. In one example, a method includes obtaining a synchronized ECG signal and a PCG signal from a patient, converting the PCG signal to a PCG mel-spectrogram, entering the ECG signal and the PCG mel-spectrogram as input to a trained specialized model configured to output a classification output based on the ECG signal and the PCG mel-spectrogram, the trained specialized model trained with labeled ECG and PCG signal pairs using a foundation model trained with unlabeled ECG and PCG signal pairs, and storing the classification output in memory and/or displaying the classification output on a display device.

Abstract: Various methods and systems are provided for an automated clinical exam workflow. In one example, method comprises performing a signal quality check of an electronic stethoscope at a first recording location on a subject, recording physiological data for an exam at the first recording location via the electronic stethoscope in response to the signal quality check satisfying a quality threshold, and outputting a signal quality alert in response to the signal quality check not satisfying the quality threshold. In this way, clinically relevant data may be obtained with reduced user effort and fewer manual inputs.

Abstract: The present disclosure provides methods, devices, and systems for determining a state or condition of a subject. A method for determining a state or condition of a heart of a subject may include using a monitoring device comprising a plurality of sensors comprising an electrocardiogram (ECG) sensor, an audio sensor, and other sensors to measure data including ECG data and audio data from an organ of the subject and transmitting the data wirelessly to a computing device. A trained algorithm may be used to process the data, such as the ECG data, the audio data, and other data to determine the state or condition of the organ of the subject. More specifically, the trained algorithm can be customized for a specific indication or condition. An output indicative of the state or condition of the heart of the subject may be provided on the computing device or monitoring device.

Abstract: A primary ion source subassembly for use with a secondary ion mass spectrometer may include a unitary graphite ionizer tube and reservoir base. A primary ion source may include a capillary insert defining an ionizer aperture. An ionizer aperture may be centrally arranged in an outwardly protruding conical or frustoconical surface, and may be overlaid with a refractory metal coating or sheath. Parameters including ionizer surface shape, ionizer materials, ionizer temperature, and beam stop plate orifice geometry may be manipulated to eliminate ghost images. A graphite tube gasket with a dual tapered surface, or an externally threaded graphite tubular connecting body, may promote sealing of a source material cavity.

Abstract: A method for querying metadata associated with media, such as multimedia and/or streaming media, on a computer network includes separating the metadata into keywords. The keywords are compared with valid keywords. A score is calculated in accordance with the degree of similarity between the keywords and valid keywords. If the degree of similarity is above a threshold, the metadata is qualified as valid metadata. Valid metadata is available for comparison and correction of other (invalid) metadata.

Abstract: This invention relates to the recording and display three-dimensional (3D) images, notably in real-time video capture. This invention focuses on the ability to alter vergence instantaneously through software in order to amend disparities caused by differences between focal length and vergence distance. No mechanical means are necessary for amending both horizontal and vertical disparity. The ability to vary vergence allows selected images to be made to appear behind, level with, or in front of a display screen. While the invention is useful for consumer displays in television and films, the invention may also be used, for example, for visualizing weather, for mapping, for seismic surveys or for aircraft flight control. It is applicable, in real time, throughout the electro-magnetic spectrum particularly in the visible, infra-red and microwave portions.

Abstract: By defining an angular separation in a train of sequential images, and using an interlaced sequence of pairs of images matched by that defining angle, it is possible to create live 3D video from a single camera mounted on a remote vehicle as though in the in the immediate vicinity of the object being viewed. Such a camera can be mounted on a moving vehicle such as a plane or a satellite In addition, computational power is provided to adaptively (and predictively) smooth out motion irregularities between these image pairs, so that smooth 3D video may be obtained. Continual feature-based correlation between successive frames allows corrections for various transformations so that there is a one-on-one correspondence in size, projection, orientation, etc. between matched frames, which enables capture and display of smooth 3D video.

Abstract: The Lexyl Online Group Reservations System is a network computer system and method in which a groups travel coordinator may gather information from Internet hotel booking engines and hotels in their desired destinations worldwide. The invention accomplishes this by collecting all necessary information from the group travel coordinator. It then uses this information to conduct a search of the Internet for rooms fitting the group coordinators needs. Once its search is completed, the system will automatically notify the hotel group managers through electronic mail. The group managers are then invited through this electronic mail invitation to enter the system and view the group travel coordinators booking needs. Once they have the required information, the system allows the hotel managers to respond with all necessary information about their hotel for the group travel coordinator to make their decision.
