Patent ID: 8082707

Claim:
A vibration damping system, comprising: a window structure that comprises two separate layers of material that are both substantially transparent at visible optical wavelengths for humans, said two separate layers being spaced-apart from one another by a first distance in an arrangement by which at least portions of said two separate layers are substantially parallel to one another, thereby forming a space between said two separate layers of material of said window structure in which said space includes a gaseous material; wherein said first distance is in the range of 0.001 inches (0.025 mm) to 0.050 inches (1.27 mm), inclusive so as to provide air-film vibration damping for said window structure; and wherein said thickness of the two separate layers of material is in the range of 0.050 inches (1.27 mm) to 1.00 inches (25.4 mm), inclusive.
