    摘要: An inflatable barrier allows separating air in a first space from air in a second space to provide containment.
    The inflatable barrier may include an inflatable bag with edge seals in the form of parallel tubes. The bag receives air from an air mover through a first opening. It has a carrier for a vent that releases air while the bag stays inflated. A tension rod prevents the bag from bulging out of shape. The bag may be hung from an expandable rod. An internal channel may route air through the whole bag.
    The inflatable barrier may comprise an outer sleeve and two or more inflatable inner chambers. The circumference of a main sleeve matches the circumference of a combination of the inner chambers. The inner chambers include an air inlet/outlet. The outer sleeve may have connector halves to couple the barrier with another barrier, or to couple the main sleeve with a top, a bottom, or an extension.

    摘要: Embodiments herein relate to a ground sealing arrangement for a portable flood barrier further comprising a vertical wall. The ground sealing arrangement is arranged to be positioned on the ground. The ground sealing arrangement comprises a main sealing layer forming a main body of the ground sealing arrangement. The main sealing layer is impermeable to water. The ground sealing arrangement further comprises a bottom sealing layer arranged on a ground-facing underside of the main sealing layer. The bottom sealing layer is attached to the main sealing layer at a distance L from a peripheral edge of the main sealing layer which is most distal from the first edge of the ground sealing arrangement such that the bottom sealing layer has a free end extending from the point where the bottom sealing layer attaches to the main sealing layer towards the peripheral edge of the main sealing layer, and comprises a highly flexible and/or glutinous material which is stretchable and sticks to the ground when the material is soaked with water.

    摘要: An improved bi-fold shutter that includes a more efficient coupling mechanism at a hinge point suited to facilitate opening and closing the bi-fold shutter with greater ease. In one embodiment, the shutter may be designed for a window such that the shutter, when closed, is relatively close to the face of the associated window, and when open, forms an awning or overhang. The shutter includes an improved coupling mechanism at a hinge point between a first shutter portion and a second shutter portion. The improved hinge point shifts a direction of force needed to maneuver the shutter when moving the shutter from one position to another. The shift in opening and closing force directions improves the efficiency by which the shutter can be operated. In some embodiments, the shutter may be hand-operated. In other embodiments, the shutter may be powered.

    摘要: 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.

    摘要: A window locking apparatus includes a proximal cross brace, a distal cross brace, a first track brace, and a second track brace. The first track brace is positioned parallel to the second track brace. The proximal cross brace is perpendicularly positioned in between the first track brace and the second track brace. The distal cross brace is perpendicularly positioned in between the first track brace and the second track brace, wherein the proximal cross brace and the distal cross brace are positioned offset of each other. The proximal cross brace is rotatably connected to the first track brace and removably mounted to the second track brace. The distal cross brace is rotatably connected to the first track brace and removably mounted to the second track brace. The removable connections of the second track brace allows the window locking apparatus to be installed or removed from a window.
