摘要： A blink detection apparatus includes an eyelid state index value measurement unit configured to chronologically measure an eyelid state index value, and a signal processing device. The signal processing device is configured to determine that a blink occurs when a change width of the measured eyelid state index value from a baseline that is a reference value of the eyelid state index value in a case where eyelids are in an opened state exceeds a magnitude of a threshold from the baseline, to count the number of times when the change width of the measured eyelid state index value from the baseline exceeds the magnitude of a tentative threshold from the baseline, and to set the threshold to a tentative threshold at which change in the number of times with respect to the tentative threshold is minimal.

摘要： A head set (2) comprises a brain electrical activity (EEG) sensing device (3) comprising EEG sensors (22) configured to be mounted on a head of a wearer so as to position the EEG sensors (22) at selected positions of interest over the wearers scalp, the EEG sensing device comprising a sensor support (4) and a flexible circuit (6) assembled to the sensor support. The sensor support and flexible circuit comprise a central stem (4a, 6a) configured to extend along a center plane of the top of the head in a direction from a nose to a centre of the back of a wearers head, a front lateral branch (4b, 6b) configured to extend across a front portion of a wearer's head extending laterally from the central stem, a center lateral branch (4c, 6c) configured to extend across a top portion of a wearer's head essentially between the wearer's ears, and a rear lateral branch (4d, 6d) configured to extend across a back portion of a wearer's head. The sensor support (4) comprises a base wall (401) and side walls (402) extending along edges of the base wall to form an essentially flat “U” shaped channel (403) in which the flexible circuit (6) is inserted and the base wall comprise EEG sensor orifices (404) to allow access to the EEG sensor contacts or electrodes on the flexible circuit.

摘要： The present disclose generally relates to systems and methods for active titration of one or more cranial or peripheral nerve stimulators to treat obstructive sleep apnea. The active titration can be accomplished in an automated fashion by a closed-loop process. The closed-loop process can be executed by a computing device that includes a non-transitory memory storing instructions and a processor to execute the instructions to perform operations. The operations can include defining initial parameters for the one or more cranial or peripheral nerve stimulators for a patient; receiving sensor data from sensors associated with the patient based on a stimulation with the one or more cranial or peripheral stimulators programmed according to the initial parameters; and adjusting the initial parameters based on the sensor data.
