Abstract

A sleep onset detector comprising a mounting member (6) which is adapted to be carried or worn by a user; a radiation source (LED) and a radiation-sensitive device (TR) which are mounted on the mounting member (6) so that, when the latter is so carried or worn and the user has substantially closed his eyes, radiation from the radiation source (LED) will be reflected by an eyelid and/or eyelashes of the user so as to be directed onto the radiation-sensitive device (TR), whereas, when the user's eyes are fully open, the radiation from the radiation source (LED) will not be reflected by an eye, eyelid or eyelashes of the user onto the radiation-sensitive device (TR); and signal-producing means (3), controlled by said radiation-sensitive device (TR), for producing a signal whenever the user closes his eyes for at least a predetermined length of time. <IMAGE>
