System And Method For Characterizing The Sleep Of An Individual
The invention relates to a system for characterising the sleep of an individual, the characterisation system comprising: a measuring device for measuring a brain activity signal representing the brain waves; a central electronic unit for identifying, in a range of frequencies of between 9 and 16 Hz, a smaller range of sleep spindles of the individual, the smaller range of sleep spindles comprising the brain wave frequencies of the sleeping individual, having an amplitude higher than 15 μV and a duration of between 0.5 seconds and 2 seconds, and comparing, with a threshold, at least one parameter of the brain activity signal of the awake individual in the range of frequencies corresponding to the smaller range of sleep spindles; and a communication interface connected to the central unit and used to emit a warning signal perceptible by the individual when the parameter of the brain activity signal in the range of frequencies corresponding to the smaller range of sleep spindles exceeds the threshold.

- 1. System for characterization of sleep of an individual, the system for characterization comprising:
a measuring device adapted to measure a brain activity signal representative of the brain waves, an electronic central unit adapted to: identify, in a range of frequencies from 9 to 16 Hz, at least one reduced range of sleep spindles specific to the individual, the reduced range of sleep spindles comprising frequencies of brain waves of the sleeping individual having an amplitude greater than 15 μV and a duration comprised between 0.5 second and 2 seconds, compare at least one parameter of the brain activity signal of the awake individual in the range of frequencies corresponding to the reduced range of sleep spindles, to a threshold, a communication interface linked to the central unit and adapted to emit a warning signal perceptible to the individual when the parameter of the brain activity signal in the range of frequencies corresponding to the reduced range of sleep spindles exceeds the threshold.
- 11. Method for characterization of sleep of an individual comprising the steps consisting in:
measuring a brain activity signal representative of brain waves. identifying, in a range of frequencies from 9 to 16 Hz, at least one reduced range of sleep spindles specific to the individual, the reduced range of sleep spindles comprising frequencies of brain waves of the sleeping individual having an amplitude greater than 15 μV and a duration comprised between 0.5 second and 2 seconds, comparing at least one parameter of the brain activity signal of the awake individual in the range of frequencies corresponding to the reduced range of sleep spindles, to a threshold, and emitting a warning signal perceptible to the individual when the parameter of the brain activity signal in the range of frequencies corresponding to the reduced range of sleep spindles exceeds the threshold.
