Definitions

• the present invention relates to a method of slumber de- tection (sleep-onset), i.e. a method to be used for surveying an individual, preferably continuously, in order to establish the moment when said individual is about to fall asleep or is about to loose consciousness.
• sleep-onset a method to be used for surveying an individual, preferably continuously, in order to establish the moment when said individual is about to fall asleep or is about to loose consciousness.
• the invention is particularly adapted for use within such technical areas in industry, transport or other technical areas in which individuals are engaged in surveying and/or control ⁇ ling functions having a monotonous character and in which the falling asleep or the loss of consciousness results in imminent danger or in a highly risky situation.
• Individuals who more frequently encounter such situations are e.g. car drivers, air ⁇ craft pilots, locomotive drivers, industrial process supervisors etc.
• detectors and detecting methods e.g. the so called "dead man's grip"; the method of attaching an accel erometer on the head of an individual (head drop); the detection of the eye movements of an individual ; the detection and analysis of the pattern of output signals produced by an individual (e.g. the movements of the steering wheel or of a control lever).
• the object of the present invention is to provide a 5 : method of slumber detection which is highly reliable and which opens up for the possibility of designing a slumber detection system which is simple, reliable and which, at least in the near future, will be well suited for mass production.
• the invention is based on the knowledge of the possi ⁇ bility of detecting immediately from EEG-signals (Electro
• Magnetometers having such a sensitivity and such in ⁇ terference suppression which renders possible the detec ⁇ tion of magnetic fields generated by the v ery small nerv
• a SQUID thus provides a possibility of directly inter ⁇ linking an individual and an apparatus via magnetic fields.
• the price of a SQUID is, at least today, probably to high for mass application.
• said hyper sensitive magnetometer is attached in a position for continuously detecting the signal pattern caused by feeble variations in the magnetic field of the brain of said individual.
• the magnetometers used are magnetometers based on a combina ⁇ tion of fibre optics and magnetostrict ve alloys having a sensitivity of 10 "12 to lO -13 Tesla.
