A method includes obtaining at least one breathing audio sample of a user captured using earbuds worn by the user. The method also includes converting the at least one breathing audio sample to a breathing spectrogram configured as an image. The method further includes processing the breathing spectrogram using a trained multi-task convolutional neural network (CNN) to identify a breathing rate and a breathing depth of the user. In addition, the method includes outputting the breathing rate and the breathing depth of the user.

In one embodiment, a method includes accessing, from a first sensor of a wearable device, motion data representing motion of a user and determining, from the motion data, an activity level of the user. The method includes selecting, based on the activity level, an activity-based technique for estimating the breathing rate of the user, which is used to determine a breathing rate of the user. The method further includes determining a quality associated with the breathing rate and comparing the determined quality with a threshold. If the determined quality is not less than the threshold, then the method includes using the determined breathing rate as a final breathing-rate determination for the user. If the determined quality is less than the threshold, then the method includes activating a second sensor of the wearable device and determining, based on data from the second sensor, a breathing rate for the user.

A cloud or other network-based multimodal dialogue system is used to conduct automated screening interviews by engaging with conversational AI over a device of the user's choice (smartphone, tablet, laptop) from the comfort of their home. A screening interview will typically guide a user to blow towards a microphone, use signals from the microphone to calculate amplitudes, and use the amplitudes to calculate a flow rate and a flow volume. Contemplated systems and methods can be deployed in an automatically scalable cloud environment allowing it to serve an arbitrary number of end users at a very small cost per interaction. No special devices unique to the task are needed, which makes the technology accessible to a vast number of users. The technology can be natively equipped with real-time speech and video analytics modules that extract a variety of features of direct relevance to clinicians, thus allowing for measurement of multiple subsystems (motoric, phonatory, resonatory) in conjunction with lung function.

A wearable cardioverter defibrillator (WCD) having a processor configured to receive a signal indicating a position and/or movement of the ambulatory patient while the ambulatory patient is wearing the support structure receive the ECG signal, determine from an ECG signal whether a shock criterion is met, determine a confirmation time period and/or a response time period based on the position and/or movement of the ambulatory patient, determine from the ECG signal whether the shock criterion is met after the confirmation time period has elapsed, cause the user interface to generate the shock alert signal based on the shock criterion determined after the confirmation time period has elapsed, and control the discharge circuit to discharge the stored electrical charge when a predetermined time period has elapsed after the shock alert signal.

The present invention solves a problem that it is difficult for conventional information processing apparatuses to obtain objective information on the gut condition. An information processing apparatus 100 includes: a sound information acquiring unit 141 that acquires sound information regarding abdominal sounds, which are sounds emanating from the abdomen, of a user; a gut score acquiring unit 149 that acquires a gut score related to a gut condition of the user, using input information containing the sound information acquired by the sound information acquiring unit 141 and learning information prepared in advance; and a gut score output unit 161 that outputs the gut score acquired by the gut score acquiring unit 149. Accordingly, it is possible to obtain objective information on the gut condition.

Embodiments detect obstructive sleep apnea (“OSA”) by a user. Embodiments receive audio data emanating from the user while the user is sleeping, the audio data including multiple distinct frequency bands. Embodiments analyze the audio data to detect patterns in frequency content that matches two or more formants of a plurality of formants, the two or more formants indicating a position of a tongue of the user. Based on the analyzing, embodiments determine when the tongue has moved from a forward position to a rear position in an oral cavity of the user. Embodiments generate a signal indicating an OSA episode when it is determined that the tongue has moved from a forward position to a rear position.

A system having a scope with a longitudinal length extending between a proximal end and a distal end includes a plurality of markers spaced along the longitudinal length. The system also includes a disassociation and positioning device that is configured to enhance unsedated transnasal endoscopic procedures by at least partially occluding the vision of a patient while enabling body cavity access, and optionally record and sense body functions such as temperature, heart rate and oxygenation of the blood stream. The system further includes a sensor integrated into the distraction device, wherein the sensor is configured to detect the markers on the longitudinal length of the scope.

A method of monitoring respiration with an acoustic measurement device, the acoustic measurement device having a sound transducer, the sound transducer configured to measure sound associated with airflow through a mammalian trachea, the method includes correlating the measured sound into a measurement of tidal volume and generating at least one from the group consisting of an alert and an alarm if the measured tidal volume falls outside of a predetermined range.
