Claim 0:
1. A system comprising:
a bed having a mattress comprising an air chamber; and
a central controller comprising:
an enclosure configured to enclose elements of the central controller;
a pressure sensor in fluid communication with the air chamber of the mattress;
a pump configured to, responsive to activation by a pump motor, add air to the air chamber of the mattress when the pump motor is energized;
a power supply connected to the pump motor and configured to selectively energize 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 pressure sensor, pressure data indicative of pressure applied to the air chamber by a person on the mattress;
determining, from the pressure data, a rate of change value indicative of change over time of the pressure data;
comparing the rate of change value to a movement threshold value;
responsive to determining that the rate of change value is greater than the movement threshold value, determining that the person is moving on the mattress;
transmitting the pressure data to the external server for analysis; and
receiving, from the external server, second data that has been analyzed and filtered.
