More Information
Summary:The invention provides a system (10) for configuring an air flow into and/or out of an air mask (32) for configuring atmospheric conditions of air within the mask. The system includes a sensing means (14) and an air flow control means (16). A controller (20) receives readings from the sensing means and based on these controls the air flow level in order to move a level of the sensed atmospheric parameter towards a pre-set target level. The controller implements an iterative adjustment procedure, adjusting a level of the air flow in multiple steps, using feedback from the sensing means to guide each step.
