SELF-CONTAINED BREATHING APPARATUS, COMPONENT THEREOF, AND BATTERY COMPARTMENT THEREFOR

Abstract: a digital display device is provided. for example, a digital display device may include a rigid housing, a compressible layer over at least a portion of the rigid housing, and a rigid cover. the rigid housing defines an internal chamber and an opening to a battery compartment. the battery compartment is adapted to receive a battery in a position with a longitudinal axis of the battery being substantially parallel to the opening. the compressible layer defines an opening that is coterminous with the opening to the battery compartment. the rigid cover is selectively attachable to the rigid housing such that, when the rigid cover is selectively attached to the rigid housing, at least a portion of the compressible layer is sandwiched between the rigid cover and the rigid housing and at least a portion of the rigid cover at least partly compresses a corresponding portion of the compressible layer.
