ABSTRACT:
The present invention relates to two modules containing electronic equipment, one relatively small, and one relatively large, that will be physically connected and used for extended operation in an environment where the ambient atmosphere contains moisture filled air or some other specified environmental contaminant. An absorber such as desiccant of a prescribed amount is contained within at least the relatively large module to control the absolute humidity and/or environmental contaminants within each module during extended operation in the ambient environment. Permeable wall portions are placed in the region between the relatively small module and the relative large module to allow for moisture and/or other specified environmental contaminants to pass from the relatively small module to the relatively large module. As such, the lifespan of the small module can be extended.
