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.
Claims15
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.

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.
