摘要： A wearable device for sensing vital signs includes a housing defining an interior cavity. An optical unit is positioned inside the interior cavity. The optical unit includes one or more light emitters that emit optical signals, at least one polarizer orientated to block optical signals having a predetermined polarity direction, and one or more light sensors that receive optical signals that pass through the at least one polarizer. An acoustic unit is positioned inside the interior cavity, and has a microphone to receive acoustic signals that enter into the interior cavity. The acoustic signals are used to non-invasively estimate blood pressure.

摘要： The proposed technology relates to a method for indicating a risk for coronary artery disease. A sound recording is obtained (100) covering a plurality of heartbeats, a plurality of heart sounds are identified (200) in the sound recording, and a plurality of segments are obtained (300) from the sound recording. A frequency power measure is determined (400) based on the signal strength of a first frequency window of a period in the diastole, an amplitude of the fourth heart sound is determined (500) based on the plurality of heart sounds and the plurality of segments, and an indication of a heart rate variability is determined (600) based on the plurality of heart sounds. The indication of the risk for coronary artery disease is then determined (700) based on the frequency power measure, the amplitude of the fourth heart sound, and the indication of the heart rate variability.

摘要： A chest-worn sensor device, such as a device for daily at-home monitoring of cardiopulmonary health conditions, includes an audio and/or visual interface that provides cues to assist a user in performing a measurement sequence. The sensor device may detect whether there are any body posture issues or device contact issues. In response to detecting an issue, the sensor device provides and audio and/or visual cue to the user indicating the issue. The sensor device may provide additional cues throughout the measurement sequence, such as a cue that a measurement is being taken, a cue for the user to change body posture, and a cue for the user to remove the sensor device.

摘要： 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.

摘要： A lightweight inflatable vest is provided with embedded listening devices. Once inflated, the vest enables a physician to hear amplified lung sounds and heart beats and rhythms of a patient wearing the vest, via connection to a smart phone application, through a patient portal, or the like. By using the device on a patient, a physician is provided with an accurate way to perform a respiratory and heart health assessment of the patient during a telehealth visit.

摘要： A metallic diaphragm disk incorporating a piezoelectric material bonded thereto and operatively coupled to a base rim of a housing provides for closing an open-ended cavity at the first end of the housing. At least one inertial mass is either incorporated in or attached to the housing. A plastic film adhesively bonded to at least one of an outer rim of the housing or an outer-facing surface of the disk provides for receiving an adhesive acoustic interface material to provide for coupling the housing to the skin of a test subject.
