A sleep-monitoring cap includes interconnected electrodes embedded within a body of the sleep-monitoring cap. The interconnected electrodes are located at positions across a central transverse region, below and along a side of each eye, and on a rear mid-region of a person's head when wearing the sleep-monitoring cap. The sleep-monitoring cap includes a vibratory device embedded within the sleep-monitoring cap, wherein the vibratory device is connected to the interconnected electrodes. The sleep-monitoring cap includes processing circuitry embedded within the sleep-monitoring cap. The processing circuitry is configured to monitor, convert, process, and store brain wave activity retrieved by the interconnected electrodes from the person wearing the sleep-monitoring cap; determine whether the monitored brain wave activity includes low amplitude mixed-frequency waves and if so, activate the vibratory device; determine whether the monitored brain wave activity includes theta waves followed by vertex sharp waves and if so, activate the vibratory device.

This invention mainly discloses an EOG-based sleep staging method which is used to improve of an accuracy of automatic sleep judging result. The method may be executed by a processor and comprises steps of reading a to-be-test data having a variation depending on time of EOG generated by a user during a sleep process; acquiring a plurality of eye movement characteristics based on a variation of the EOG of a period, with the characteristics including an eye movement ratio, a blink count, a low frequency power ratio, a high frequency power ratio, an alpha rhythm ratio, a spindle rhythm ratio, a delta rhythm ratio and an average amplitude of eletrooculogram (EOG) signals; and determining a sleep state of the period is a “WAKE stage”, a “REM stage”, a “S1 stage”, a “S2 stage”, or a “SWS stage” based on the EOG characteristics. Furthermore, a computer readable medium with stored programs, and electronic apparatuses are provided.

The present disclosure provides electroretinography devices configured to detect biopotential signals from an eye of a subject. In some embodiments, the device is configured to prevent the subject's eyelids from closing over the device when placed in contact with the anterior surface of the subject's eye. In some embodiments, the device has a Young's modulus of no more than about 50 MPa. In some embodiments, the device includes a diffusing or refracting element configured to scatter, focus or diverge incident light. In other embodiments, the device includes a void through which incident light can enter the subject's eye without passing through any portion of the device.

An electrode sensor is provided. The electrode sensor can include a conductive sensor area that is at least partially covered by hydrogel. The hydrogel can be conductive and adhere to skin. A receptacle can form an open container surrounding the conductive sensor area and the hydrogel.

The present invention relates to a device for assessing the ability of a person to carry out one or more activities, comprising an input unit for receiving physiological and/or behavioural data of the person, the physiological and/or behavioural data being related to one or more first level activities, a determination unit for determining a performance grade of the person regarding each first level activity based on the received physiological and/or behavioural data, and an assessment unit configured to assess an ability grade of the person to carry out one or more second level activities based on the determined performance grade, wherein each second level activity relates to one or more associated first level activities, wherein the assessment unit is further configured to output information indicative of the assessed ability grade.

Disclosed is an audio-headset for acquisition of a bio-signal from a subject, including a first earpiece; a second earpiece; an arch connecting the first earpiece and the second earpiece; the arch including a hub (4); wherein the arch, the first earpiece and the second earpiece are configured so that the earpieces are placed over a subject's ears when the audio headset is worn by the subject; and at least one posterior branch (1) having a first end extending from the hub and a second free end; the at least one posterior branch (1) including a concave surface with a radius of curvature, a collapsed state when the headset is not worn by the subject and an expanded state when the headset is worn by the subject.

Methods of analysis to extract and assess brain data collected from subject animals, including humans, to detect intentional and unintentional brain activity and other unexpected signals are disclosed. These signals are correlated to higher cognitive brain functions or unintended, potentially adverse events, such as a stroke or seizure, and to translation of those signals into defined trigger events or tasks.
