US Patent 7460304 Thermal vision mask

The invention is a thermal imaging camera lens that has an LCD display mounted on the opposing side of the camera, which is integrated into a fire mask visor. The fire mask visor is used in conjunction with an oxygen mask. The thermal imaging lens is directed along the same line of sight as the user's, which provides for greater ease of use in hazardous situations. However, the thermal imaging lens can be rotated to a desired angle and line of sight of the end user. A sealant can be applied to the perimeter of the thermal imaging system housing and the visor to prevent the introduction of smoke and/or hazardous gases from entering the interior side of the visor.
