Stevenson screens may also be known as a cotton region shelter, an instrument shelter, a thermometer shelter, a thermoscreen, or a thermometer screen. Its purpose is to provide a standardised environment in which to measure temperature, humidity, dewpoint, and atmospheric pressure. It is white in color to reflect direct solar radiation.

Passively adapted to the temperate-arid climate of southern California, the major design feature of the Solar Umbrella is a shading solar canopy. Rather than deflecting sunlight, this contemporary solar canopy uses 89 amorphous photovoltaic panels to transform the sunlight into usable energy, providing 95% of the residence's electricity. At the ...
Two clear view screens on the navigation bridge of a tugboat. 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.
Electric screens can be wall-mounted, ceiling-mounted or ceiling recessed. These are often larger screens, though electric screens are available for home theater use as well.
