Abstract: A dimmer mechanism is movable by a motor that is powered by solar-charged supercapacitors between a first configuration, in which the dimmer mechanism blocks little of the interior of a skylight tube to maximize light throughput into a room, and a second configuration, in which the dimmer mechanism blocks more of the interior of a skylight tube to reduce light throughput into the room.

Abstract: Embodiments are described of devices for concealing and/or protecting a portion of a member, such as the base of a post, which devices can be easily applied to the member at any time. These embodiments include a plurality of components adjustably connected to one another so as to provide a snug fit of the device against the member to be protected, regardless of initial variations from the expected dimensions of the member. Further device embodiments are self-adjusting to provide a snug fit regardless of subsequent changes in the dimension of the member over time.

Abstract: In a tubular skylight, an Aluminum sheet having corrugations that may be in a waffle pattern is formed with a hole that is pressed into a curb which is fastened over the turret of a roof-mounted skylight flashing. Roof tiles above the dome of the skylight are placed onto the sheet, while below the dome the sheet is placed over roof tiles and manually conformed thereto, owing to the corrugations. Any water that leaks past tiles above the dome will be directed by the sheet around the curb and down onto the tops of tiles that are below the dome, thereby providing a water seal for the skylight. Clips can be used to hold the lower edge of the sheet onto the tiles.

Abstract: A valve for selectively blocking the light passageway of a skylight includes a cylindrical shroud and first and second semicircular butterfly valve elements that pivot on respective axles within the shroud to selectively block the skylight. The axles can ride on a common motor-driven cam between a horizontal orientation to block the skylight and a vertical orientation to allow light to pass. The motor can be powered by a universal power supply that can operate at anywhere from below 100 volts to above 270 volts.
