ABSTRACT:
Closure member control systems, including door control systems for barrier housings, and associated methods are disclosed. One aspect of the invention is directed toward a closure member control system that includes a closure member positioned to cover a portion of an opening in a structure (e.g., a barrier housing). The closure member has a closed position where the closure member covers the portion of the opening and an open position where the closure member does not cover the portion of the opening. The system further includes a control device operatively coupled to the closure member that urges the closure member to remain in the closed position when the closure member is in the closed position and urges the closure member to remain in the open position when the closure member is in the open position. In certain embodiments, the control device can include at least one forcing mechanism.
