Patent ID: 8749899

Claim:
A system for enabling viewing in an environment, wherein the environment includes a partition for partitioning the environment from an external environment, and the partition includes an exterior surface and an interior surface, comprising: an exterior housing, adapted to be positioned on the surface of the partition and to be slidably moveable thereabout, including a frame, which frame further has a central opening for enabling viewing the environment therethrough, wherein the exterior housing includes a magnet therein having a facing surface adapted to face the exterior surface of the partition, which facing surface has a polarity, and wherein the system further comprises an interior housing, adapted to be positioned on the interior surface of the partition and to be slidably moveable thereabout in alignment and coordination with and under the control of slidable movement of the exterior housing, including a frame which includes a magnet therein having a facing surface adapted to face the interior surface of the partition, which facing surface has a polarity, wherein the polarity of the exterior housing frame magnet facing surface and the interior housing frame magnet facing surface are the opposite of each other and interact so as to enable the movement of the exterior housing to control the movement of the interior housing, and wherein the interior housing frame further has a central opening for enabling viewing the environment therethrough, wherein the interior housing is comprised of buoyant material, enabling it to float if it becomes separated from the exterior housing during use, and wherein the interior housing further includes sealed airspace.
