1. A controller for controlling airflow into a pressure-mitigation device that includes a plurality of chambers, the controller comprising:
a structural body that includes an egress interface to which at least one tube is connectable, the at least one tube allowing the egress interface to be fluidly coupled to the pressure-mitigation device,
wherein the egress interface has a plurality of outlets, each of which is associated with a different one of the plurality of chambers;
a plurality of transducers that are housed inside the structural body and that are configured to generate a plurality of electrical signals,
wherein each electrical signal of the plurality of electrical signals is representative of a rate at which air is flowing through a corresponding one of the plurality of outlets into a corresponding one of the plurality of chambers to maintain a desired pressure; and
a processor that is housed inside the structural body and that is configured to:
examine the plurality of electrical signals to identify changes in the rates at which air is flowing through the plurality of outlets into the plurality of chambers,
infer movements of a living body that is situated on the pressure-mitigation device based on the changes in the rates at which air is flowing through the plurality of outlets into the plurality of chambers, and
establish values for a characteristic of the living body over time based on the movements.
