Abstract

Sleep mask for reducing sleep inertia. In an embodiment, the sleep mask comprises a foam layer having a shape that covers both of a human subject'"'"'s eyes so as to attenuate ambient light. Visual stimulation element(s), configured to emit light, are positioned between the foam layer and the subject'"'"'s eyes. In addition, a plurality of sensors positioned on the forehead of the subject collect electroencephalogram (EEG), electrooculogram (EOG), and electromyogram (EMG) signals. A soft exterior cover houses the foam layer, the visual stimulation element(s), and the sensors. The sleep mask further comprises processor(s) that determine and record each sleep stage of the subject, determine when to wake the subject, and, when it is determined to wake the subject, control the visual stimulation element(s) to wake the subject using emitted light.

Claims

1. A sleep mask for reducing sleep inertia, the sleep mask comprising:

a foam layer having a shape that, when the sleep mask is worn by a human subject, covers both eyes of the human subject so as to attenuate ambient light;

one or more visual stimulation elements that, when the sleep mask is worn by the human subject, are positioned between the foam layer and the eyes of the human subject, wherein the one or more visual stimulation elements are configured to emit light;

a plurality of sensors that, when the sleep mask is worn by the human subject, are positioned on a forehead of the human subject and are configured to receive a plurality of signals from the human subject, wherein the plurality of signals comprise an electroencephalogram (EEG) signal, an electrooculogram (EOG) signal, and an electromyogram (EMG) signal;

a soft exterior cover that houses at least the foam layer, the one or more visual stimulation elements, and the plurality of sensors;

a memory; and

at least one processor that, when the sleep mask is worn by the human subject, is configured to

determine each sleep stage of the human subject,

record each determined sleep stage in the memory,

determine when to wake the human subject, and,

when the at least one processor determines to wake the human subject, control the one or more visual stimulation elements to emit light to wake the human subject.

2. The sleep mask of claim 1, wherein the sleep mask, when worn by the human subject, covers both ears of the human subject so as to attenuate ambient noise.

3. The sleep mask of claim 1, wherein the foam layer comprises one or more cuts that house the one or more visual stimulation elements.

4. The sleep mask of claim 1, wherein the soft exterior cover comprises fabric.

5. The sleep mask of claim 4, wherein the fabric comprises a polyester blend.

6. The sleep mask of claim 1, wherein each of the one or more visual stimulation elements comprises a light-emitting diode.

7. The sleep mask of claim 1, wherein determining each sleep stage of the human subject comprises matching one or more of the plurality of signals to a pattern.

8. The sleep mask of claim 1, further comprising one or more communication interfaces for transferring data.

9. The sleep mask of claim 1, further comprising one or more vibration elements configured to emit vibrations.

10. The sleep mask of claim 9, wherein the at least one processor is further configured to control the one or more vibration elements to emit vibrations to guide the human subject towards an awake state.

11. The sleep mask of claim 9, wherein the at least one processor is configured to determine whether to control the one or more visual stimulation elements or the one or more vibration elements to affect a sleep state of the human subject.

12. The sleep mask of claim 1, wherein the at least one processor is configured to determine one or more of a duration, intensity, and pattern of the light emitted by the one or more visual stimulation elements.

13. The sleep mask of claim 1, wherein determining when to wake the subject is based on at least one determined sleep stage of the human subject.

14. The sleep mask of claim 1, further comprising an interface for defining one or more personalized rules to be executed by the at least one processor, wherein the one or more personalized rules are configured to be calibrated to the human subject.

15. The sleep mask of claim 14, wherein the at least one processor is configured to determine a strategy for implementing a desired sleep architecture based on the one or more personalized rules.

16. The sleep mask of claim 1, wherein the emitted light is configured to guide the human subject towards an awake state.

17. The sleep mask of claim 16, wherein the at least one processor is configured to control the one or more visual stimulation elements to awaken the human subject gradually.

18. The sleep mask of claim 1, further comprising one or more audio elements configured to emit sound, wherein the at least one processor is further configured to control the one or more audio elements to emit sound to guide the human subject towards an awake state.

19. The sleep mask of claim 1, wherein the at least one processor is configured to control the one or more visual stimulation elements to awaken the human subject within a predetermined period of time.

20. The sleep mask of claim 1, wherein the emitted light is blue light.

21. The sleep mask of claim 1, further comprising an interface for communicating with one or more external controls, wherein the one or more external controls influence one or more environmental conditions in an environment of the human subject.

22. The sleep mask of claim 1, further comprising one or more cooling elements that are configured to, when the sleep mask is worn by the human subject, cool at least a portion of the human subject.

23. The sleep mask of claim 1, wherein the at least one processor is configured to provide a graphical user interface to a user.
