ABSTRACT:
The present invention provides a system for controlling ambient pressure within an enclosed environment. The system is comprised of means for outputting a first signal, generally of a predetermined value. That signal is received in a detecting and comparing means which determines the relative change in the signal over time. Based upon the determination of the signal change, a second signal is generated. The second signal is received by an active device which is capable of altering the ambient pressure within the enclosed environment and responds to the second signal.
