A cardiac rhythm management system provides for the trending of a third heart sound (S3) index. The S3 index is a ratio, or an estimate of the ratio, of the number of S3 beats to the number of all heart beats, where the S3 beats are each a heart beat during which an occurrence of S3 is detected. An implantable sensor such as an accelerometer or a microphone senses an acoustic signal indicative heart sounds including S3. An S3 detector detects occurrences of S3 from the acoustic signal. A heart sound processing system trends the S3 index on a periodic basis to allow continuous monitoring of the S3 activity level, which is indicative of conditions related to heart failure.

A system is provided for monitoring patients with dysphagia, or swallowing impairments, that monitors muscle movement during intensive swallowing exercises to provide adjuvant visual feedback from surface electromyography.

Systems and methods for detecting a medical condition using a mobile computing device are provided. In some aspects, a computer receives sound measurements generated at a microphone. The computer receives thorax movement measurements recorded by a motion measurement unit in parallel with recording the sound measurements at the microphone. The computer determines a relationship between the sound measurements and the thorax movement measurements. The computer determines a medical condition based on the relationship between the sound measurements and the thorax movement measurements. The computer provides an output representing the medical condition.

A device for generating sensory stimuli, corresponding to sensory stimuli emanating from a reference person, for a child comprises a receiving unit for receiving a data stream from a device for acquiring sensory stimuli, emanating from a reference person, and a transducer unit, which is coupled to the receiving unit and is controllable by the data stream. The transducer unit generates at least either body-borne sound, which corresponds to the heart sounds, described by the data stream, of the reference person, or movements, which correspond to the movements, described by the data stream, of the reference person, or airborne sound, which corresponds to the airborne sound generated by the reference person and is described by the data stream.

The present disclosure provides a computer implemented method for automatic detection of teeth clenching and/or teeth grinding in a dataset representing the level of biting force vs. time of a subject, the method comprising the steps of a) calculating a threshold level of biting force assigned to time t=t.sub.1 based on a background level determined from the dataset at a prior time t=t.sub.1T.sub.back, where T.sub.track is a first predefined period of time,b) checking the level of biting,and if the level of biting force at time,t, exceeds the threshold level assigned to time t for a second predefined period of time, T.sub.clench/grind, then assigning an event of teeth clenching to time t,c) if an event of teeth clenching has been assigned to time t, then either waiting a predefined period of time 10 T.sub.wait,or waiting until the level of biting is below the threshold for another predefined period of time T.sub.end, d) if no events of teeth clenching and/or teeth grinding have been assigned for a third predefined period of time T.sub.silence, then repeating steps a)-c),e)if events of teeth clenching and/or teeth grinding have been assigned for a third predefined period of time T.sub.silence, then repeating only steps b)-c).

A bio-vibration device for use by a user having a finger for sensing vibration signals in an individual includes a finger coupler device, a vibration sensor and a communications circuit. The vibration sensor is affixed to the finger coupler device and is configured to be pressed against a selected site of the individual so as to sense a vibration signal therefrom. The communications circuit is responsive to the vibration sensor and is configured to transmit the vibration signal to a remote device.

Systems, methods, and devices include a multi-sensor scanning device for characterizing a health parameter. A scanning portion formed at an end of the multi-sensor scanning device includes a first sensor assembly. The first sensor assembly has a glass section forming a contact surface and/or one or more LEDs operable to provide electromagnetic waves to an interior of the glass section.

Systems, methods, and devices include a platform with a transparent material which defines a first measurement surface. Light surfaces are positioned to provide light into the transparent material and cause a Frustrated Total Internal Reflection (FTIR) event responsive to contact at the first measurement surface. The system also includes one or more wearable devices having a base material operable to cover a portion of a human body. An inner surface of the base material defines a second measurement surface. Furthermore, one or more sensors disposed on the base material are operable to collect data at the second measurement surface. Additionally, the health parameter monitoring system presents at the display, such as a virtual reality (VR) headset, locomotion regimen information. The system collects first health parameter data from the first measurement surface based on the FTIR event; and/or second health parameter data from the second measurement surface.
