Issued 2019-10-15
Inflatable Air Mattress System With Detection Techniques
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.
- 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.
