Clear view screen – IMU NOTES

A clear view screen or clearview screen is a glass disk mounted in a window that rotates to disperse rain, spray, and snow.
A clear view screen is typically driven by an electric motor at the center of the disk, and is often heated to prevent condensation or icing.
Clear view screens were originally developed in the mid-1930s for automobiles as a better option than standard windshield wipers .
On ships, a clear view screen is usually on the bridge and rotates at high speed (~1500 rpm). Clear view screens are also used in locomotives and rail transport.
