Appendix
1. Goggles for isolation of a user's eyes from the outside environment comprising:
a frame including a transparent portion adapted to cover at least of the user's eyes; and
a sealing pad adjacent to the frame, said sealing pad comprising a compliant and resiliently
deformable gelatinous elastomer suitable to conform under pressure to form a substantially airtight seal
between the frame and at least a portion of the user's face adjacent to the sealing pad.
37. Goggles for isolation of the user's eyes from the outside environment comprising:
a frame including a transparent portion adapted to cover the user's eyes;
a sealing pad adjacent to the frame, said sealing pad comprising a compliant and resiliently
deformable gelatinous elastomer suitable to conform under pressure to form a substantially airtight seal
between the frame and the user's face;
wherein the gelatinous elastomer is a synthetic polymer gel of the type used in the Kitecko
Ultrasound Standoff Pad manufactured by 3M Corporation of St. Paul, Minnesota;
wherein each gelatinous elastomer is sufficiently compliant that when a compressive pressure of
approximately 100 grams per square inch and approximately 3500 grams per square inch is applied to
the top surface of a thin strip of the gelatinous elastomer, the height of the strip can be compressed by
approximately 25 percent of the height of the strip; and
further comprising a thin, distortable toroidal membrane having a smooth and regular surface
which encloses the entire sealing pad in an airtight manner.
