A method for providing electrical stimulation to a user as a user performs a set of tasks during a time window, the method comprising: providing an electrical stimulation treatment, characterized by a stimulation parameter and a set of portions, to a brain region of the user in association with the time window; for each task of the set of tasks: receiving a signal stream characterizing a neurological state of the user; from the signal stream, identifying a neurological signature characterizing the neurological state associated with the task; and modulating the electrical stimulation treatment provided to the brain region of the user based upon the neurological signature, wherein modulating comprises delivering a portion of the set of portions of the electrical stimulation treatment to the brain region of the user, while maintaining an aggregate amount of the stimulation parameter of the treatment provided during the time window below a maximum limit.

A technique to detect an eye potential of a wearer of an eyewear by using an electrode abutting on the glabella of the wearer has been known, but it is desirable to surely cause the electrode to abut on the glabella so as to prevent deterioration in the detection accuracy of detecting a biosignal indicating an eye potential, myogenic potential, brain wave or the like. In view of this, an eyewear including: a frame; a first electrode that abuts on a glabella of a wearer of the eyewear; and an electrode holding unit that holds the first electrode such that a distance between the frame and the first electrode is changeable is included.

According to an aspect of the present inventive concept there is provided a method for eye tracking, comprising: capturing a sequence of digital images of an eye of a user; outputting data including said sequence of images to an image processing unit; processing said data by the image processing unit to determine a sequence of positions of the eye, each position being indicative of a gaze direction, acquiring biosignal data representing an activity of the eye; and in response to detecting closing of the eye based on the acquired biosignal data, pausing at least one of said capturing, said outputting and said processing. A system for implementing the method is also disclosed.

A system and method for the acquisition and analysis of physiological data, such as for example, electrophysiological data including but not limited to EEG, EKG, EMG EOG, and biomechanical data relating to breathing and/or respiration to provide further insight to the person's health and/or behavior. A plurality of self-contained sensors having an electrically-conducting interface, an amplifier, an analog to digital converter, and a wireless transceiver may be used. Each of the self-contained sensors may be about the size of a watch battery. A sensor array embedded within a conductive fabric may also be used to detect physiological data. The conductive fabric may be included a plurality of conduct nodes rising out of a surface of the conductive fabric or may be a quilted meshwork having a plurality of sections, each section forming a conductive surface for detecting physiological data.

A method and apparatus for diagnosing and/or treating mood disorders, such as depression, is provided. Right vestibular function in subjects diagnosed with a mood disorder is diminished compared with subjects who do not have a mood disorder. Accordingly, a method and apparatus for determining right vestibular function in a subject is provided, from which a diagnosis of a mood disorder may be determined. Stimulation of the vestibular system of a subject diagnosed with a mood disorder may reduce symptoms of the mood disorder in the subject. A method and apparatus for registering a subject's response to stimulation of the vestibular system and providing therapeutic vestibular stimulation based on the subject's response is provided. A subject's response to stimulation of the vestibular system may be based on measurements of nystagmus in the subject.

To provide a biological signal measuring equipment that can perform the measurement in the same manner as the case of measuring a wave motion of a short period, even in the case of measuring the wave motion of a long period generated in a head portion. A biological signal measuring equipment used in the measurement of the biological signal in a head portion, has a jaw contact portion that comes into contact with a forehead; an occiput contact portion that comes into contact with the occiput; and a supporter that is interposed in a front and rear direction of the head portion and is supported by the head portion by using the jaw contact portion and the occiput contact portion as ends.

A multi-electrode array with individually isolated electrodes each configurable for a target-containing carrier and a method for fabricating the array are disclosed. In an exemplary embodiment, the array includes a substrate; and a plurality of electrodes disposed on the substrate. Each electrode of the plurality of electrodes has a conductive tip-end and an insulated remainder. A first electrode of the plurality of electrodes has a first configuration selected to bring a conductive tip end of the first electrode in proximity to a first target structure, and a second electrode of the plurality of electrodes has a second configuration selected to bring a conductive tip end of the second electrode in proximity to a second target structure. The first configuration and the second configuration are different. A first contact of the plurality of contacts may be electrically coupled to the first electrode through the substrate.

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.

Unique methods and bio-imaging systems are introduced herein for self-automated self-operable biomedical devices and methods for bio-signal monitoring, such as electrocardiograms (ECG), heart rate, and other vital signs, requiring no trained medical assistance or minimal assistance. In particular, methods and devices disclosed herein may require no dedicated medical resources, generate diagnostic quality results, and provide for motion artifact correction without inducing discomfort or irritation. Moreover, long term recording is realizable. Such methods and devices reduce the backlog of patients at out-patient wards as well as emergency response in remote areas.
