Automated air mattress bed system

A mattress assembly, comprising:

• a plurality of gas-filled chambers each having a top surface, the top surfaces of the chambers collectively composing a top surface of the mattress assembly;
• a plurality of composite sensors, each composite sensor of the plurality of composite sensors being associated with a corresponding one of the plurality of the chambers, each composite sensor comprising:
• a pressure sensor arranged to measure a pressure at a wall of the corresponding chamber;
• and
• a temperature sensor arranged to measure a temperature of the corresponding chamber;
• a plurality of chamber regulators, each chamber regulator being in fluid communication with a corresponding one of the plurality of chambers, each chamber regulator being configured, during operation of the mattress assembly, to pump gas at a first temperature and gas at a second temperature to the corresponding chamber, the first temperature being greater than the second temperature;
• and
• a controller in communication with the composite sensors and the chamber regulators, the controller being programmed to:
• receive, from at least one composite sensor of the plurality of composite sensors, state data comprising pressure and temperature information for the chamber corresponding to the at least one composite sensor;
• determine, based upon the received state data, an information about a patient's position relative to the corresponding chamber;
• and
• based on the patient's position, control the chamber regulator for the corresponding chamber to modify a pressure and/or a temperature of the corresponding chamber.
