Abstract

An air mattress adjustment method includes adjusting the air mattress to a received user pressure setting, learning a level of pressure in the air mattress at a first plurality of times with respect to the user pressure setting, monitoring the level of pressure in the air mattress at a second plurality of times, determining that the pressure of the air mattress at one of the second plurality of times is out of range, and based on the determining, adjusting the pressure of the air mattress.

First claim

What is claimed is:

1. A system comprising:
a bed having a mattress that is adjustable and configured to support a user during a sleep session;
a pressure sensor configured to sense user pressure on the mattress and to generate pressure readings;
a controller comprising one or more processors and memory, the controller configured to:
receive the pressure readings from the pressure sensor;
determine, from the pressure readings, an orientation of the user;
determine, from the pressure readings, a current sleep-state of the user occupying the bed;
determine that a desired sleep-state of the user is different than the current sleep-state;
access data defining a plurality of adjustment-allowed sleep-states that each define a sleep-state in which the user is occupying the bed and in which it has been identified that the mattress is permitted to be adjusted for the user;
responsive to a determination that the current sleep-state is one of the adjustment-allowed sleep-states while the user is occupying the bed:
select an adjustment to the mattress based on the determined orientation; and
adjust the mattress according to the selected adjustment, having an effect of encouraging the user to transition to the desired sleep-state; and

responsive to a determination that the sleep-state is not one of the adjustment-allowed sleep-states while the user is occupying the bed, not adjusting the mattress.

2. The system of claim 1 , wherein to adjust the mattress according to the selected adjustment, the controller is further configured to:
issue a command to a pump that is in fluid communication with the mattress and that is configured to change air-pressure of the mattress.

3. The system of claim 1 , wherein possible sleep-states include at least one of the group consisting of awake, Rapid Eye Movement (REM), deep sleep, light sleep, and restless.

4. The system of claim 1 , wherein the determined orientation of the user is one of the group consisting of on-back, on-side, and on-stomach.

5. The system of claim 1 , wherein the current sleep-state of the user occupying the bed is of the group consisting of rapid eye movement (“REM”) and non-rapid eye movement (“NREM”).

6. A controller comprising one or more processors and memory, the controller configured to:
receive pressure readings from a pressure sensor configured to sense user pressure on a mattress of a bed and to generate pressure readings, wherein the mattress is adjustable and configured to support a user during a sleep session;
determine, from the pressure readings, an orientation of the user;
determine, from the pressure readings, a current sleep-state of the user occupying the bed;
determine that a desired sleep-state of the user is different than the current sleep-state;
access data defining a plurality of adjustment-allowed sleep-states that each define a sleep-state in which it has been identified that the mattress is permitted to be adjusted for the user;
responsive to a determination that the current sleep-state is one of the adjustment-allowed sleep-states while the user is occupying the bed:
select an adjustment to the mattress based on the determined orientation; and
adjust the mattress according to the selected adjustment, having an effect of encouraging the user to transition to the desired sleep-state; and

responsive to a determination that the sleep-state is not one of the adjustment-allowed sleep-states while the user is occupying the bed, not adjusting the mattress.

7. The controller of claim 6 , wherein to adjusting the mattress according to the selected adjustment, the controller is further configured to:
issue a command to a pump that is in fluid communication with the mattress and that is configured to change air-pressure of the mattress.

8. The controller of claim 6 , wherein possible sleep-states include at least one of the group consisting of awake, Rapid Eye Movement (REM), deep sleep, light sleep, and restless.

9. The controller of claim 6 , wherein the determined orientation of the user is one of the group consisting of on-back, on-side, and on-stomach.
