An oral appliance for treating sleep apnea in a user includes a mouthpiece configured for being positioned in an oral cavity of the user, and at least one pulse oximeter attached to the mouthpiece. According to an aspect, the pulse oximeter is configured to monitor actual oxygen saturation levels of hemoglobin of the user when the oral appliance is positioned in the oral cavity of the user. The oral appliance may include an additional sensor attached to the mouthpiece that includes at least one of an airflow sensor, a pressure sensor, a noise detector, and an actigraphy sensor.

Disclosed herein are breathing disorder identification, characterization and diagnosis methods, devices and systems. In general the disclosed methods, devices and systems may rely on the characterization of breath sound amplitudes, periodic breath sounds and/or aperiodic breath sounds to characterize a breathing disorder as obstructive (e.g. obstructive sleep apnea—OSA) or non-obstructive (e.g. central sleep apnea—CSA).

A BRDC sign detecting system includes: a processor, and a memory storing program instructions that cause the processor to obtain, with respect to a bovine developing bovine respiratory disease complex (BRDC) within a time period required for a fattening process, data indicating a condition of the bovine during a predetermined time period in which the bovine did not yet develop the BRDC, and obtain data indicating a condition, during a predetermined time period, of a bovine that has not developed BRDC perform machine learning with respect to a correspondence relation between the obtained data indicating the condition during the predetermined time period and information indicating whether BRDC is developed, and infer, by inputting data indicating a condition of a new bovine during the predetermined time period into a learned model generated by performing the machine learning, information indicating whether the new bovine will develop BRDC and output an inference result.

Examples disclosed herein are relevant to monitoring and treating sensory conditions affecting an individual. Sensors and intelligence integrated within a sensory prosthesis (e.g., an auditory prosthesis) can automatically obtain objective data regarding the ability of one or more of an individuals senses during day-to-day activities. A treatment action can be taken based on the objective data. Further disclosed herein are techniques relating to reducing the gathering of irrelevant sensory input and automatically transmitting relevant data to a caregiver device.

Passively monitoring a user's breathing with a device can include identifying breathing modes of the user's breathing and responsive to detecting a trigger mode based on the identifying, generating an instruction adapted to the trigger mode. The instruction can be conveyed to the user via the device. The monitoring can include determining phases of the user's breathing with the device. Determining the phases can include receiving acoustic signals generated by an acoustic sensor in response to a user's breathing and generating acoustic data comprising features extracted from the acoustic signals. Phases of the user's breathing can be determined by classifying the acoustic data using a machine learning model trained based on signal processing of motion signals generated by a motion sensor in response to human breathing motions. Though trained using signal processing of motion signals, the machine learning model is trained to classify acoustic data.

An acoustic sensor is configured to provide accurate and robust measurement of bodily sounds under a variety of conditions, such as in noisy environments or in situations in which stress, strain, or movement may be imparted onto a sensor with respect to a patient. Embodiments of the sensor provide a conformable electrical shielding, as well as improved acoustic and mechanical coupling between the sensor and the measurement site.

A breathing biofeedback device, having a microphone configured to acquire sounds of a user's breathing; a controller communicatively connected with the microphone, the controller processing the signals acquired by the microphone to produce an output signal, the controller processing the signal whereby the microphone signal is first pre-amplified to a voltage level that can be processed by an audio envelope detector circuit, the envelope detector signal is then fed into the analog-to-digital converter input of the controller allowing it to constantly sample the input volume level, the controller then controlling the output volume level fed to the headphones utilizing a digitally controlled variable-gain amplifier, wherein the output signal is not modified in any manner from the original input, except in volume; and a pair of earphones connected with the controller and configured to convey the output signal to the user.

A system for treating a patient, including a computerized device with a display and a communication interface for communicating with remote mobile devices, one or more sensors for measuring medical parameters of a user, wherein the sensors are controlled by the computerized device and transfer recorded measurements to the computerized device, an application executed on the computerized device; wherein the application allows, a remote practitioner with a remote mobile device to communicate with the computerized device to control the sensors.

Maxillary devices and Mandibular devices each have a first housing connectable to a tooth of a user or connectable or integral with a teeth covering, wherein the housing encloses an on-board circuit board and a power source. The first housing of the maxillary devices has a tooth connecting portion, a palate housing portion and/or a buccal housing portion. The first housing of the mandibular devices has a tooth connecting portion and a sublingual portion. Each of the palate housing portion and the buccal housing portion enclose a stimulator having an electrode electrically connected to the on-board circuit board and the power source, and can enclose a sensor and/or a medicament dispenser. The sublingual portion encloses a sensor and a medicament dispenser each of which are in electrical communication with the microprocessor of the on-board circuit board.

An endoscope system includes: a light source for emitting pulsed light; an endoscope device having an image sensor for capturing images of an inside of a subject in accordance with timing for generating the pulsed light; a processing device for controlling the light source and the endoscope device; first and second microphones configured to collect sound and connected to the processing device; a holding member for holding the first and second microphones at a location separated from the subject; and an acquisition unit configured to acquire positional relationships between the first microphone, the second microphone, and the subject. The processing device is configured to: extract a vibrational frequency of first sound emitted by the subject from the sound collected by the first and second microphones, based on the positional relationships; and control the light source to generate the pulsed light in accordance with the vibrational frequency of the first sound.
