Abstract
An aviator's night vision system (10) includes a small, compact, portable battery pack (68) separate from, and unattached to, a helmet (12), but comprising a container housing a battery (78) with a goggle assembly receptacle of the type that is mounted on the helmet. The goggle assembly receptacle of the portable battery pack housing includes engaging means (86 & 88), electrical contacts (90 & 92), and an orientation ridge (106) of the same type found on the helmet mounted receptacle (14). With this small portable battery pack, a goggle assembly can be removed from the helmet mounted goggle-assembly receptacle, snapped onto the portable battery pack receptacle, and thereafter used by hand for enhancing night vision.
