A controller in electrical communication with the at least one pair of electrodes is included and the control may also be configured to measure a conductivity or impedance between the pair of electrodes and to determine a gastric residual volume of the stomach based on the measured conductivity or impedance.

An electronic apparatus includes an array of microphones for detecting audible sounds generated by a patient and for generating audio information representing the detected audible sounds, a first beamformer having a first adaptability speed and configured to generate first audio information and first noise information from the audio information, a second beamformer having a second adaptability speed which is slower than the first adaptability speed, the second adaptive beamformer configured to generate second audio information and second noise information from the audio information, an audio classification unit for generating audio classification information based on the first audio information, a head movement detection unit for generating head movement information based on at least one of the second audio information, the first noise information, and the second noise information, and a diagnosis unit for determining a sleep apnea diagnosis based on the audio classification information and the head movement information.

Disclosed herein are systems and methods for detecting snore and automatically adjusting a bed system to a position intended to mitigate the snore. The bed system can include a mattress, an adjustable foundation, and a controller having a processor. The processor can be configured to generate, in response to sensing snoring from a user of the bed system, instructions for tilting the adjustable foundation to a predetermined position such that an angle between a head portion of the adjustable foundation and the ground is greater than an angle between a foot portion of the adjustable foundation and the ground. The ground can be a horizontal plane. The predetermined position can be a position intended to mitigate snore.

The invention relates to a device for detecting physiological sounds, the device comprising a thin film, and a first conductive element for conducting sounds, the conductive element being located on the thin film. In some embodiments, the said detection device comprises a cavity; the thin film is a part of the cavity. Wherein the volume of the cavity is variable; wherein the said volume of the cavity is reduced, either when the conductive element contacts the skin of a human or a mammal, or before the conductive element contacts the skin of a human or a mammal, or after the conductive element contacts the skin of a human or a mammal. The device of the inventions can significantly improve the detection sensitivity and resolution of physiological sounds, and can give early diagnosis pathological sounds, for example, heart failure can be detected by means of heart sound diagnosis.

Provided herein is a method and system for the estimation of apnea-hypopnea index (AHI), as an indicator for Obstructive sleep apnea (OSA) severity, by combining speech descriptors from three separate and distinct speech signal domains. These domains include the acoustic short-term features (STF) of continuous speech, the long-term features (LTF) of continuous speech, and features of sustained vowels (SVF). Combining these speech descriptors may provide the ability to estimate the severity of OSA using statistical learning and speech analysis approaches.

The present invention is directed to multimodal communications means for transmitting signals representing physiological, performance, and contextual information associated with a subject. In an exemplary embodiment, the multimodal communications means includes multiple radio subsystems (or modes) that enable connection to an external monitoring device to be acquired in a wide range of settings where a single radio mode would be ineffective. Additionally, combining the multimodal communications means of the invention with real-time data-processing allows the communications functionality to be engaged only when data determined to be relevant to the user is identified.

According to embodiments of the present invention, an air conduction sensor for detecting a sound from a user is provided. The air conduction sensor includes a housing comprising an opening, wherein a rim of the opening is configured to at least substantially attach to a skin or a clothing of the user; a microphone coupled to the housing such that there is an air gap between the microphone and the skin or the clothing, and wherein the microphone is configured to detect the sound. A system and a method for monitoring a health condition of a user are also provided.

This document describes a system for determining positioning of an intubation tube in a patient. The system can include a first acoustic sensor configured to be disposed to listen to one of a lung and a stomach of the patient and to provide a first signal. The system includes a signal processing unit, coupled to the first acoustic sensor, configured to analyze spectral components of the first signal and determine whether a frequency of the spectral components of the first signal are characteristic of sounds induced by ventilation via the intubation tube of airflow to the lung or the stomach of the patient.

Wearable physical health testing systems and associated devices and methods are disclosed herein. A wearable system configured in accordance with embodiments of the present technology can include, for example, a communications hub, and a plurality of physical health testing devices. The communications hub and the plurality of physical health testing devices can integrated into an article of clothing, such as a jacket, a shirt, or a body suit. The physical health testing devices are in wired and/or wireless communication with the communications hub. Each physical health testing device is configured to generate physical health data of a user and to transmit generated physical health data to the communication hub and/or a user's mobile device. The wearable system provides an automated physical exam that can be performed at user's homes or other convenient locations.
