1. A control unit for a dynamic support apparatus having at least one actuator, the control unit comprising:
- a pump connected to the at least one actuator for causing actuation thereof;
a sensor detecting a pressure of the at least one actuator; and
a control system for controlling the pump, the control system in communication with the sensor and receiving a signal indicative of the pressure of the at least one actuator therefrom;
wherein the control system controls the pump to actuate the at least one actuator at least in response to the pressure detected by the sensor;
wherein the control system commands the pump to increase the pressure of the at least one actuator if the pressure detected by the sensor drops below a current pressure setpoint by more than a prescribed deadband;
wherein the control system evaluates a user activity level based at least on the signal from the sensor indicative of the pressure of the at least one actuator, the evaluation of the user activity level being based on a pressure variability as determined by a high-pass filter; and
wherein the evaluation of the user activity level is made with respect to an activity reference pressure indicative of typical activity.

Abstract
A dynamic support system includes a control system for controlling inflation and deflation of at least one actuator having an inlet connectable to the a control unit of the dynamic support system. The control unit may be in communication with a sensor and may control inflation and deflation of the at least one actuator in response to information provided by the sensor.
