A combination awning and shutter (1) having at least two panels (4, 5, 15, 16, 17) of substantially rectangular configuration foldably attached along contiguous sides so that when folded together and supported by support rods (8) or scissor hinges (18) and brackets (19) can be maintained in an angular awning position and when unfolded act as a storm or security shutter over a window or door opening and further securable by the support rods secured in eye bolts (11) on each side of an opening.

In example implementations, a track of a vertically stacking door is provided. The track includes a vertical track, a track coupling coupled to the vertical track, a first curved track portion coupled to the track coupling, a second curved track portion coupled to the track coupling, and a ramp coupled to the vertical track before the track coupling.

A single panel roll-up door comprising a panel, Roller brackets, rollers, a left roller series, a right roller series. Further the back side of the panel, wherein the surface of the back side of the panel comprising a first plateau, a first recessed channel, a plateau, a recessed channel, and a last recessed channel. Wherein the single panel roll-up door is coupled to a framed opening of a container, and the panel of the single panel roll-up door can be selectively in an opened position or closed position. When in the opened position the panel rest in the guide tracks in parallel.

Embodiments of the present disclosure provide adjustable lighting devices for use in photography lighting systems. In one embodiment, an adjustable lighting device comprises at least two panel sections and a light element. The at least two panel sections are each configured to act as a light reflector or flag, and are rotatably coupled to each other such that each panel section is freely rotatable relative to its one or more adjacent panel sections. The light element is coupled to one side of a first panel section of the panel sections, and configured to direct light substantially in a direction away from the one side of the first panel section.

A barrier system includes a roll-up barrier comprising a plurality of slats hingedly connected, a guide system, and a drive system. Each slat of the plurality of slats includes a central portion having a first thickness, a top portion, and a bottom portion. At least one of the top portion or the bottom portion having a second thickness less than the first thickness. The top portion of each slat overlaps the bottom portion of an adjacent slat forming an overlapping region having the first thickness when the barrier is in a closed configuration. The guide system is configured to guide movement of the roll-up barrier. The drive system configured to transition the roll-up barrier between open and closed configurations along the guide system.

A folding hanger includes a hook extending from an upper end of a hinge pin for suspending the pin. First and second hanger arms each have proximal and distal ends and define a support surface therebetween. Each proximal end has a stop. A knuckle having a hole extends from each proximal end. The pin passes through the holes along an axis, coupling the arms and hook whereby the arms are movable between extended and folded configurations. The stops abut when the arms are extended, and are separated when folded. The hanger has a center of gravity when the arms are extended and suspended by the hook such that the axis is angled relative to vertical in a first direction and the stops bias abutting. The arms each have a center of gravity such that angular movement of the axis past an unstable equilibrium causes the arms to move toward folded.

In one embodiment, an adjustable lighting device comprises at least two panel sections and a light element. The at least two panel sections are each configured to act as a light reflector or flag, and are rotatably coupled to each other such that each panel section is freely rotatable relative to its one or more adjacent panel sections. The light element is coupled to one side of a first panel section of the panel sections, and configured to direct light substantially in a direction away from the one side of the first panel section.

A door and window floodproofing assembly for preventing flood waters from entering a building includes an inflatable sealer apparatus and a battery cover apparatus. The inflatable sealer apparatus comprises a sealer body having a sealer front side, a sealer back side, and a sealer perimeter defining a sealer inside. The sealer inside is inflatable and dimensioned to fit within a door jamb or a window frame. A sealer flap is flexibly coupled to the sealer perimeter adjacent the sealer back side. The battery cover apparatus comprises a panel having a panel front side, a panel back side, and a panel perimeter. A plurality of latches is coupled to the panel front side adjacent the panel perimeter. A plurality of receivers is selectively engageable with the plurality of latches. Each receiver is coupled to the door jamb or the window frame.

This disclosure presents a safe high speed roll-up door with spiral brackets. To enable a high speed operation, robust spiral brackets having efficient spacing are provided to guide the plurality of sectional slats. Durable and low noise signature rollers are used. A unique assembly configuration of the slats and the tracks guiding the rollers enable quick replacement of each individual roller without disassembling the door. A double-belt counter weight mechanism balances the door and incorporates safety sensors that prevent loosening the belts when the door is jammed. The belts are further adjustable using ratchets such that adjustment for the horizontal balance as well as weight position is made effortless. In all, the high speed roll-up door using sectional slats performs faster and quieter, withstands greater loads, and lasts longer than other existing roll-up doors with spiral brackets.

A solar powered smart window includes a light diffuser configured to convert an incident direct solar radiation to a diffusive light toward interior direction, a light diffuser positioner, a driving mechanism, a solar panel, and a control unit. The control unit moved the light diffuser from a predetermined opened position to a closed position and to hold the light diffuser at the closed position with latch mechanism, when the output power of the solar panel exceeds a threshold for over a duration time. The controller releases the latch mechanism and to cause the light diffuser to return to the predetermined opened position when the output power lowers below threshold for over the duration time. A method includes storing a predetermined condition, monitoring the output power, comparing the output power with the predetermined conditions, making decision whether a positional transition is necessary, and causing the transitional transition or maintaining current position.
