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 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;
initiating a timer upon determining that the user of the air mattress system moved;
stopping the timer upon determining that the user of the air mattress system has stopped moving; and
wherein an accumulated time in the timer represents a total amount of time that the user has moved.
2. The method of claim 1 , wherein the average values are rolling average values.
3. The method of claim 1 , determining a sleep quality index based on the accumulated time.
4. The method of claim 3 , further comprising:
upon determining the sleep quality index, displaying the index to the user.
5. A bed system comprising:
an inflatable air mattress having at least a first bladder;
and
a central controller comprising:
a processor configured to:
receive a plurality of air pressure values of the first bladder;
determine a plurality of rolling average values of the first bladder using the plurality of the received air pressure values of the first bladder;
calculate a difference value between a first one of the plurality of rolling average values of the first bladder and a second one of the plurality of rolling average values of the first bladder;
compare the difference value to a threshold value;
determine, based on the comparison, whether a user of the air mattress system moved;
calculate a pressure change value using a difference between a first one of the plurality of the air pressure values of the first bladder received prior to the user movement beginning and a second one of the plurality of the air pressure values of the first bladder received after the user movement has terminated;
compare the calculated pressure change value to a threshold value; and
determine, based on the comparison, a position of the user of the air mattress system.
6. The bed system of claim 5 , wherein the first bladder is sized and positioned to support the user on a first side of the bed system, and further comprising a second bladder sized and positioned to support a second user on a second side of the bed system.
7. The bed system of claim 5 , wherein the central controller further comprises a pump.
8. A bed system comprising:
an inflatable air mattress;
and
a central controller comprising:
a processor configured to:
receive a plurality of air pressure values;
determine a plurality of average values using the plurality of the received air pressure values;
calculate a difference value between a first one of the plurality of average values and a second one of the plurality of average values;
compare the difference value to a threshold value;
determine, based on the comparison, whether a user of the air mattress system moved;
initiate a timer upon determining that the user of the air mattress system moved;
stop the timer upon determining that the user of the air mattress system has stopped moving; and
wherein an accumulated time in the timer represents a total amount of time that the user has moved.
9. The system of claim 8 , wherein the average values are rolling average values.
10. The bed system of claim 8 , and further comprising a pump fluidically connected to the inflatable air mattress.
11. The system of claim 8 , wherein the processor is configured to determine a sleep quality index based on the accumulated time.
12. The system of claim 11 , wherein the processor is configured to:
upon determining the sleep quality index, display the index to the user.
13. The bed system of claim 8 , and further comprising an adjustable foundation sized and configured to adjustably supporting the inflatable air mattress and a pump fluidically connected to the inflatable air mattress.
14. A method comprising:
receiving, at a central controller of an air mattress system, a plurality of air pressure values of a first bladder;
determining a plurality of rolling average values of the first bladder using the plurality of the received air pressure values of the first bladder;
calculating a difference value between a first one of the plurality of rolling average values of the first bladder and a second one of the plurality of rolling average values of the first bladder;
comparing the difference value to a threshold value;
determining, based on the comparison, whether a user of the air mattress system moved;
calculating a pressure change value using a difference between a first one of the plurality of the air pressure values of the first bladder received prior to the user movement beginning and a second one of the plurality of the air pressure values of the first bladder received after the user movement has terminated;
comparing the calculated pressure change value to a threshold value; and
determining, based on the comparison, a position of the user of the air mattress system.
15. The method of claim 14 , wherein the first bladder is sized and positioned to support the user along a length of the air mattress system.
