Sleep monitoring system
Sleep systems having embedded sensors are described. In one aspect, a sleep system includes a mattress and one or more force sensors embedded within the mattress. The force sensors are positioned within the mattress to sense movement of an occupant of the mattress. The sleep system also includes one or more processors coupled with the one or more force sensors. At least one of the processors is configured to determine sleep state information for the occupant based on data obtained from one or more of the force sensors.
1. A sleep system comprising:
one or more force sensors associated with a mattress, the force sensors being positioned to sense an occupant of the mattress;
a memory storing characteristic information associated with a plurality of predetermined sleep positions; and
one or more processors coupled with the one or more force sensors and the memory, at least one of the processors being configured to determine, by comparing the data obtained from the force sensors to the characteristic information and based on information about relative probabilities of sleep positions, a sleep position associated with the occupant.
2. The sleep system of claim 1 , wherein the characteristic information represents a force distribution pattern for each of the plurality of sleep positions.
3. The sleep system of claim 1 , wherein the one or more processors are further configured to separately determine a sleep position for a second occupant based on data obtained from one or more of the force sensors that are positioned to sense the second occupant.
4. The sleep system of claim 1 , wherein the information about the relative probabilities of sleep positions is used by the one or more processors to resolve an ambiguity based on the data obtained from the force sensors.
5. The sleep system of claim 1 , wherein the one or more processors are further configured to store the sleep position associated with the occupant in memory.
6. The sleep system of claim 5 , wherein the one or more processors are further configured to store timing information in association with the stored sleep position.
7. The sleep system of claim 6 , wherein the timing information is a time when the occupant entered or exited the stored sleep position.
8. The sleep system of claim 1 , wherein at least one of the plurality of predetermined sleep positions is a position associated with sleeping on a stomach.
9. The sleep system of claim 1 , wherein at least one of the plurality of predetermined sleep positions is selected from the group that includes:
a fetus position;
a freefall position;
a log position;
a yearner position;
a solider position; and
a starfish position.
10. The sleep system of claim 1 , wherein the at least one of the processors is provided on a mobile device.
11. The sleep system of claim 1 , wherein the at least one of the processors is provided on a server.
12. The sleep system of claim 1 wherein at least one of the plurality of predetermined sleep positions is a position associated with sleeping on a back or a position associated with sleeping on a side.
13. A sleep system comprising:
one or more force sensors associated with a mattress, the force sensors being positioned to sense an occupant of the mattress;
a memory storing characteristic information associated with a plurality of predetermined sleep positions; and
one or more processors coupled with the one or more force sensors and the memory, at least one of the processors being configured to:
determine, by comparing the data obtained from the force sensors to the characteristic information and based on information about relative probabilities of sleep positions, a sleep position associated with the occupant;
store the sleep position associated with the occupant and timing information in memory, the timing information based on when the occupant entered or exited the sleep position; and
determine, based on the timing information and the stored sleep position, a most common sleep position over a period of time.
14. The sleep system of claim 13 , wherein the one or more processors are further configured to store the most common sleep position in memory.
15. The sleep system of claim 13 , wherein the one or more processors are further configured to output the most common sleep position via an output interface.
16. The sleep system of claim 13 , wherein at least one of the plurality of predetermined sleep positions is a position associated with sleeping on a back or a position associated with sleeping on a side.
17. The sleep system of claim 13 , wherein the at least one of the processors is provided on a mobile device.
18. The sleep system of claim 13 , wherein the at least one of the processors is provided on a server.
19. The sleep system of claim 13 , wherein at least one of the plurality of predetermined sleep positions is selected from the group that includes:
a fetus position;
a freefall position;
a log position;
a yearner position;
a solider position; and
a starfish position.
20. The sleep system of claim 13 , wherein at least one of the plurality of predetermined sleep positions is a position associated with sleeping on a stomach.
