The disclosed technology generally relates to a hearing device configured to adjust its settings when it detects the hearing device user is experiencing stress related to the hearing device applying a processing scheme. The hearing device can use vital signs of the hearing device user to determine whether a user is stressed. The hearing device can also determine whether the user has become stressed as a result of applied setting or an applied processing scheme of the hearing device based on a change in the vital sign of the hearing device user. The disclosed technology also includes a method for reducing stressing when using a hearing device.

A computer-implemented diabetes management method includes a first determination of an insulin bolus related to one or more obtained glucose values and optionally the expected carbohydrate content of a meal to be ingested, a re-calculation of an insulin bolus in consideration of a user's body parameter information as measured by a body-worn sensor, providing a notification to the user if there is a significant deviation between the two calculated bolus amounts, and a user input whether the calculated insulin bolus or the re-calculated insulin bolus is selected by the user for bolus administration.

An ear-wearable electronic device comprises a motion sensor configured to generate motion information and a first respiration rate estimated using the motion information. A

PPG sensor is configured to generate PPG data and a second respiration rate estimate using the PPG data. A processor is configured to produce a respiration rate estimate using the first and second respiration rate estimates. A communication device is configured to communicate the respiration rate estimate to one or both of an external electronic device and a cloud database.

A wearable device includes a housing with a window and an electronic module supported by the housing. The electronic module includes a photoplethysmography sensor, a motion sensor, and a signal processor that processes signals from the motion sensor and signals from the photoplethysmography sensor. The signal processor is configured to remove frequency bands from the photoplethysmography sensor signals that are outside of a range of interest using a band-pass filter to produce pre-conditioned signals, and to further process the pre-conditioned signals using the motion sensor signals to reduce motion artifacts from footsteps during subject running. The device includes non-air light transmissive material in optical communication with the photoplethysmography sensor and the window that serves as a light guide for the photoplethysmography sensor. The window optically exposes the photoplethysmography sensor to a body of a subject wearing the device via the non-air light transmissive material.

The present invention is directed to a wearable system wherein elements of the system, including various sensors adapted to detect biometric and other data and/or to deliver drugs, are positioned proximal to, on the ear or in the ear canal of a person. In embodiments of the invention, elements of the system are positioned on the ear or in the ear canal for extended periods of time. For example, an element of the system may be positioned on the tympanic membrane of a user and left there overnight, for multiple days, months, or years. Because of the position and longevity of the system elements in the ear canal, the present invention has many advantages over prior wearable biometric and drug delivery devices.

An earpiece having light sources and optical sensors arranged to obtain physiological data from the tragus of an ear. At least one extra light source or optical sensor is provided such that there is redundancy. The redundancy allows for misalignment of the earpiece while still having sufficient number of light sources and optical sensors to continuously obtaining physiological data.

The present invention relates to a physical performance assessment method including the steps of: collecting a patient's motion acceleration signals for the patient's motion analysis measured from a motion acceleration sensor attached to the patient's head through a motion measurement module; and deriving a plurality of motion parameters based on the collected motion acceleration signals through a motion analysis module.

Embodiments herein relate to ear-worn devices that can track exposure to hearing degrading conditions and/or provide notifications or warnings regarding the same. In an embodiment, an ear-worn device is included having a control circuit, a microphone in electrical communication with the control circuit, an electroacoustic transducer for generating sound in electrical communication with the control circuit, and a power supply circuit in electrical communication with the control circuit, wherein the ear-worn device is configured to track exposure to hearing degrading conditions over time via at least one of the microphone and a sensor package and wherein the ear-worn device is configured to store data regarding the tracked exposure. Other embodiments are also included herein.

A closed loop system using in-ear infrasonic hemodynography and method therefor are disclosed. The system includes an in-ear biosensor system that detects biosignals including infrasonic signals of an individual, and sends the biosignals to an analysis system that identifies physiological data from the biosignals that is associated with the autonomic nervous system of the individual. External sensors can detect other physiological data of the individual during environmental conditions and under different stimuli, and send the other data and the context under which it was detected to the analysis system. The analysis system can train a machine learning model with the identified physiological data in conjunction with the other physiological data, execute actions in response to new information to adjust the autonomic nervous system of the individual, optimize their performance on tasks, and train the individual to adjust their autonomic nervous system in response to new stimuli.

A measurement apparatus includes a plurality of sensors wearable on different parts of a human body and a controller configured to acquire an output value of each of the sensors. The sensor each outputs an output value to calculate the same type of biological information by optical measurement, the controller selects either the sensor on the basis of each output value of the sensors, and determines a measured value of the biological information on the basis of an output values of the sensors selected.
