  • Patent number: 10643639
    Abstract: The present disclosure describes a system and method for determining cardiac parameters and physiological conditions of a user by analysing speech samples of said user. A user device of the user may record specifics of speech and use these specifics of speech as a speech sample of user's utterance. The user device may transmit the speech samples to a backend system. The system may isolate phonation segments from the speech samples. The system may filter one or more phonation segments. The system may isolate uttered speech segments from one or more phonation segments. The system may perform an acoustic-phonetic analysis of the uttered speech segments. The acoustic-phonetic analysis may use plurality of features for the analysis. The IPA phonemes may be used to derive speech markers that correspond to specific cardiac parameters and physiological conditions. The system may generate a resulting report after analysis which is transmitted to the user.

  • Patent number: 10599192
    Abstract: This application relates to a portable electronic device including a first sensing module and a second sensing module that are both in communication with a processor. The portable electronic device can include access ports that are formed in the housing, where the first and second sensing modules are capable of receiving an external stimulus by way of the access ports. A plate is positioned in the housing between a wall of the housing and the sensing modules. The plate and the wall define non-linear flow paths between the access ports to the first and second sensing modules. The non-linear flow paths can transmit the external stimulus to cause at least one of the first or second sensing modules to provide a detection signal to the processor that causes a display unit to present a notification that corresponds to the external stimulus.

  • Patent number: 10362997
    Abstract: A system (100) for monitoring and diagnosing heart conditions includes a sensor array (102) with accelerometers, an electrocardiogram sensor, and a system to synchronously capture and process (103, 105, or 106) composite heart signals. The system performs separation, identification and marking (201-205 or 501-509) of the signals, to extract information in cardiac vibrations. Machine learning, auditory scene analysis, or spare coding approaches can be used to resolve source separation problems. Analysis of the composite signals separates different vibration signals (302, 303, 304, 305), identifies streams for particular valve signal, and marks them with event time information with respect to a synchronous electrocardiogram signal (306). The psychoacoustic analysis mimics human auditory processing to enhance hearing of heart valve sounds by separating valve vibrations from the composite signal, and providing extraction, identification, marking and display of individual valve signals.

    Abstract: The present invention is an esophageal stethoscope with a temperature sensor and earpiece. An esophageal stethoscope has a tube with a first end and a second end, where a sound-transmitting hydrophobic cuff covers the first end of the tube. The first end of the tube has a plurality of lateral openings and a thermistor extending from the first end but within the cuff. The second end of the tube is attached to a connector and has a temperature sensor sub-assembly that extends out of the second end and is connected to the thermistor. A monoscope tube is attached to the connector at a first end and has a memory foam earpiece at a second end. The monoscope tube also preferably has a clip near the earpiece. To facilitate sound transmission, monoscope tubes of different ID sizes are used.

  • Publication number: 20150119741
    Abstract: A method of distinguishing sleep period states that a person experiences during a sleep period, the method comprising: using a non-contact microphone to acquire a sleep sound signal representing sounds made by a person during sleep; segmenting the sleep sound signals into epochs; generating a sleep sound feature vector for each epoch; providing a first model that gives a probability that a given sleep period state experienced by the person in a given epoch exhibits a given sleep sound feature vector; providing a second model that gives a probability that a first sleep period state associated with a first epoch transitions to a second sleep period state associated with a subsequent second epoch; and processing the feature vectors using the first and second models to determine a sleep period state of the person from a plurality of possible sleep period states for each of the epochs.
