Abstract: A method can be provided that includes measuring sound waves using a sound measuring device, determining, at a central controller of an air mattress system, one or more parameter values of the sound waves, comparing the one or more parameter values with values, ranges, or patterns indicative of snoring, identifying a snoring state of a user, and initiating, with the central controller, a change to one or more adjustable features of 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.

Abstract: A method and system may include transmitting a signal to a pump of an air mattress to set the pressure of the air mattress to an initial pressure; receiving, at a central controller, a user preference condition for an automatic adjustment of the pressure in the air mattress; receiving, at the central controller, an indication that the air mattress is empty; and based on determining that the user preference condition has been met and receiving the indication: detecting a change in the pressure of the air mattress beyond a threshold value; and based on the detection, adjusting the pressure of the air mattress to the initial pressure.

Abstract: This disclosure describes, among other things, techniques for waking a user by changing the user's sleep environment. In one example, a method includes receiving, at a central controller of an air mattress system, at least one user alarm setting, generating, via the central controller, at least one instruction based on the received user alarm setting, and transmitting, from the central controller, the at least one instruction to a first component of the air mattress system to adjust a feature of the first component.

Abstract: Methods and devices for monitoring the position of a subject are disclosed. One such method includes sensing pressure waves generated by the subject moving on a divided bladder comprising interleaved portions, generating signals indicative of the pressure waves for each of the interleaved portions, and sending the signals to a processor. The method further includes determining the position of the subject based on the difference between the signals from each of the interleaved portions and generating a pattern for the subject. The pattern includes the presence and/or position of the subject over time. The method further includes predicting an action such as an exit of the subject from the divided bladder based on comparing a current pattern for the subject to previous patterns for the subject.
