An exemplary hearing system that is configured to assist a user in hearing includes a behind-the-ear (BTE) component that includes a power source and an in-the-ear (ITE) component configured to fit at least partially within an ear canal of the user. The ITE component may include a microphone arranged so as to face outside of the ear canal of the user while the ITE component is worn by the user, a vent opening configured to ventilate the ear canal of the user to an environment outside of the ear canal, a receiver configured to provide an audio signal to the user based on an input audio signal detected by the microphone, and at least one of active noise control circuitry configured to reduce at least one of environmental noise entering the ear canal through the vent opening and occlusion and an active vent configured to control the vent opening.

Aspects of the present disclosure provide methods, apparatuses, and systems for closed-loop sleep protection and/or sleep regulation. According to an aspect, sleep disturbing noises are predicted and a biosignal parameter is measured to dynamically mask predicted disturbing environmental noises in the sleeping environment with active attenuation. Environmental noises in a sleeping environment of a subject are detected, input, or predicted based on historical data of the sleeping environment collected over a period of time. The biosignal parameter is used to determine sleep physiology of a subject. Based on the environmental noises in the sleeping environment and the determined sleep physiology, the noises are predicted to be disturbing or non-disturbing noises. For predicted disturbing noises, one or more actions are taken to regulate sleep and avoid sleep disruption by using sound masking prior to or concurrently with the occurrence of the predicted disturbing noises.

A method of compensating for a movement of a device worn by a user is described. The method comprises measuring, using a first sensor, a motion of a user wearing the device; measuring, using a second sensor, a motion of the device; determining a difference in the motion of the device with respect to the motion of the user; and compensating for the difference in the motion of the device with respect to the motion of the user. An electronic device for monitoring a device worn by a user is also disclosed.

A system and method for measuring the head position and postural sway of a subject is disclosed herein. The system generally includes a head position detection device, a postural sway detection device, and a data processing device operatively coupled to the head position detection device and the postural sway detection device. During the execution of the method, the position of the head of the subject is measured using the head position detection device, and the postural sway of the subject is measured using the postural sway detection device. Also, during the execution of the method, it is determined whether the subject is displacing his or her head over a prescribed range by comparing the head position information determined by using the head position measurement device to a predetermined head displacement range.

Presented is an EEG adapter device for eyewear which can be worn invisibly and continuously by the user. The eyewear adapter includes a main body configured in the form of a sleeve so that an intended temple of the eyewear can slidably fit therein, a ring configured to fit over the eyewear's temple and operable by a user to move a first EEG electrode of the eyewear adapter toward or away from the main body to ensure the first EEG electrode is adjustably positioned at FT9/FT10 of the 10-10 system. The eyewear adapter further includes a second EEG electrode and positioned in the vicinity of a bony region behind the user's ears, a third EEG electrode positioned at T9/T10 position of the 10-10 system when in use, and an electronics unit configured to receive and process EEG-related data from the first, the second, and the third EEG electrodes.

A textile-based hydrogel electrode comprises a textile-based backing layer, a conductive structure coupled to the textile-based backing layer, and a hydrogel body in contact with at least a first portion of the conductive structure, wherein the first portion of the conductive structure and the hydrogel body form an ionic interface configured to generate an electrical signal through the conductive structure corresponding to a biopotential change proximate to the textile-based hydrogel electrode.

Disclosed are novel compositions, devices, patches, systems and methods that are useful for estimating, determining, modulating and/or improving the sleep/wake and/or circadian phase of a subject (e.g., a human subject) by the dispensing of measured quantities of agents to a subject or into an environment of the subject and the continuous monitoring and/or tracking of the subject's consciousness (e.g., sleep/wake) patterns. In certain aspects, the compositions, devices, patches, systems and methods disclosed herein are capable of delivering one or more agents to a subject in response to measured consciousness patterns estimations and circadian phase estimations, thereby aligning the subject's circadian biology to the external environment and improving the quality and duration of sleep.

Novel tools and techniques are provided for assessing, predicting and/or estimating a probability that a patent is bleeding, in some cases, noninvasively. In various embodiments, tools and techniques are provided for implementing rapid detection of bleeding before, during, and after fluid resuscitation, in some instances, in real-time.

The present invention provides systems, methods, and articles for temperature conditioning a surface. An article is formed from a first layer having a plurality of openings and a second layer having a corresponding plurality of openings. At least one interior chamber constructed and configured to retain a fluid without leaking is defined between an interior surface of the first layer and an interior surface of the second layer. At least one flexible fluid supply line delivers the fluid to the at least one interior chamber. At least one flexible fluid return line removes the fluid from the at least one interior chamber. At least one control unit that is operable to selectively cool or heat the fluid is attached to the at least one flexible fluid supply line and the at least one flexible fluid return line.
