display screen 44 and the display unit 14 can be rotated
upwardly out of the line of sight of the soldier. Display
screen 44 is transparent so the soldier may see through the
screen when he is not focussing on images on the screen."
(Col. 6, lines 46-50). The various mounting arrangements in
Hanson would have taught one of ordinary skill in the art that
a camera/display could be mounted directly to a helmet or
could be mounted to headgear underneath a helmet. "According
to various embodiments of the invention, the video camera may
be responsive to visible light, infrared radiation, thermal
radiation or other particular radiation properties of the
environment which enable an accentuated view of the scene or
situation." (Col. 2, lines 12-17; see also col. 9,
lines 1-2.) Therefore, Hanson teaches one of ordinary skill
in the art that any of the cameras or night vision equipment
can be an infrared sensor camera as claimed. Hanson states
(col. 15, lines 37-39): "The invention may find a variety of
applications in the civilian environment, such as in news
reporting, fire fighting or law enforcement." Therefore, it
would have been obvious to employ the system of Hanson in a
fire fighting environment where stratified heat is present.
