Claim 14:
15. A system comprising:
a bed having a mattress comprising an air chamber; and
a central controller comprising:
an enclosure configured to enclose one or more elements of the central controller;
a plurality of sensors including at least one pressure sensor in fluid communication with the air chamber of the mattress;
a pump configured to add air to the air chamber of the mattress when a pump motor is energized;
a power supply connected to the pump motor;
a network interface configured to interact with an external server for processing of data;
one or more processors; and
computer memory storing instructions that, when executed by the one or more processors of the central controller, cause the central controller to perform operations comprising:
receiving, from the at least one pressure sensor, pressure data indicative of pressure applied to the air chamber by a person on the mattress;
determining, from the pressure data sensed by the at least one pressure sensor, a first central tendency of air pressure values;
determining, from the pressure data sensed by the at least one pressure sensor, a second central tendency of air pressure values;
calculating a difference between the first central tendency and the second central tendency;
determining movement based on the difference between the first central tendency and the second central tendency;
transmitting first data determined from data sensed by one or more of the plurality of sensors to the external server for analysis; and
receiving, from the external server, second data that has been analyzed and filtered.
