Abstract
Systems and techniques are described herein for determining sleep adequacy in a non-invasive manner. In accordance with one embodiment of the present invention, this may be done by determining waking electroencephalogram (EEG) power density of a user. Described herein is a sleep quality measuring device configured to be worn by a user that includes EEG sensors configured to contact an occipital aspect of the user's head to determine an EEG power density of the user to determine sleep adequacy.
Claims20
A sleep quality measuring device, comprising:
- a body, configured to couple to a head of a user, wherein the body comprises a body occipital portion formed to be disposed next to an occipital aspect of the head of the user;
- an electroencephalogram (EEG) sensor, disposed on the body occipital portion and configured to contact the occipital aspect when the sleep quality measuring device is worn by the user to detect EEG readings from the occipital aspect of the head of the user and output corresponding EEG data;
- and
- a controller configured to perform operations comprising:
- receiving the EEG data from the EEG sensor;
- determining, from the EEG data, a current alpha power of the user;
- comparing the current alpha power to a reference alpha power;
- determining a sleep adequacy rating based on the comparing;
- and
- outputting the sleep adequacy rating.
7 more elements
A method comprising:
- receiving, within a threshold period of time after a user has awoken when the user is free of sleep associated drugs, electroencephalogram (EEG) data from a sleep quality measuring device worn on a head of the user, wherein the sleep quality measuring device is formed to dispose an EEG sensor of the sleep quality measuring device to contact an occipital aspect of the head of the user when the sleep quality measuring device is worn on the head of the user;
- determining, from the EEG data, a current alpha power of the user;
- comparing the current alpha power to a reference alpha power;
- determining a sleep adequacy rating based on the comparing;
- and
- providing an adjustment to a sleep treatment schedule based on the sleep adequacy rating.
