1. A method comprising:
- receiving, at a central controller of an air mattress system, a plurality of air pressure values;
determining a rate of air pressure decrease using the plurality of the received air pressure values;
comparing the determined rate of air pressure decrease to a threshold value;
determining, based on the comparison, whether a user of the air mattress transitioned out of or onto the air mattress system; and
responsive to determining whether a user of the air mattress transitioned out of or onto the air mattress system, calculating a rolling average of recent received air pressure values to confirm the determination of whether a user of the air mattress transitioned out of or onto the air mattress system.

Abstract
In one example, this disclosure describes a method including receiving, at a central controller of an air mattress system, a plurality of air pressure value, determining a plurality of average values using the plurality of the received air pressure values, calculating a difference value between a first one of the plurality of average values and a second one of the plurality of average values, comparing the difference value to a threshold value, determining, based on the comparison, whether a user of the air mattress system moved.

1. A method comprising:
-
receiving, at a central controller of an air mattress system, a plurality of air pressure values; determining a rate of air pressure decrease using the plurality of the received air pressure values; comparing the determined rate of air pressure decrease to a threshold value; determining, based on the comparison, whether a user of the air mattress transitioned out of or onto the air mattress system; and responsive to determining whether a user of the air mattress transitioned out of or onto the air mattress system, calculating a rolling average of recent received air pressure values to confirm the determination of whether a user of the air mattress transitioned out of or onto the air mattress system. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A method comprising:
-
receiving, at a central controller of an air mattress system, a plurality of air pressure values; determining a rate of air pressure decrease using the plurality of the received air pressure values; comparing the determined rate of air pressure decrease to a threshold value; determining, based on the comparison, whether a user of the air mattress transitioned out of or onto the air mattress system, wherein comparing the determined rate of air pressure decrease to a threshold value comprises determining that the rate of change is a negative value indicating a decrease in air pressure; and responsive to determining whether a user of the air mattress transitioned out of or onto the air mattress system, calculating a rolling average of recent received air pressure values to confirm the determination of whether a user of the air mattress transitioned out of or onto the air mattress system.

11. A air mattress system comprising:
-
an inflatable air mattress; and a central controller comprising; a processor configured to; receive a plurality of air pressure values; determine a rate of air pressure decrease using the plurality of the received air pressure values; compare the determined rate of air pressure decrease to a threshold value; determine, based on the comparison, whether a user of the air mattress transitioned out of or onto the air mattress system; and responsive to determining whether a user of the air mattress transitioned out of or onto the air mattress system, calculating a rolling average of recent received air pressure values to confirm the determination of whether a user of the air mattress transitioned out of or onto the air mattress system. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
