When firefighters tackle a dangerous blaze, thermal imaging can be their greatest ally. It's usually integrated in a small handheld camera, helping team members to quickly locate civilians, peak through walls and identify safe passageways. Tyco's Scott Safety has now developed a face mask which includes an integrated thermal camera and display, called "Scott Sight." A small image is shown inside the mask -- similar to how Google Glass' would appear in your peripheral vision -- at nine frames per second, for up to four hours. The user can also switch between four different interfaces, as well as ambient and max temperature settings.
