Module for observation/monitoring (1) comprising: a supporting mount (2); a telescope (3) rotatably supported by said mount (2); and an opening shelter (4), also supported by said mount (2); said shelter (4) enclosing said telescope (3) within a housing volume (5) when in a closed configuration and clearing a line-of-sight access of the telescope (3) to the external environment when in an open configuration.

A retention system may comprise a bracket, a bar system, a seal and a bonded washer. The bracket may have a first portion and a second portion. The first portion and the second portion may be operatively coupled together at an angle θ. The bracket may also have a texture. The bracket may define a mounting surface. The bar system may comprise a bar installable in the bracket. The seal may be installable in the bracket and disposed beneath the mounting surface. The bonded washer may be installable on and compressible against the mounting surface.

A control panel for an enclosed space, set into a cutout in the wall of the enclosed space, that can rotate at least 180 degrees so as to be accessible from either the inside or the outside of the enclosed space.

An immersive theater is provided having a screen oriented with respect to a pitched seating area to provide an immersive theater experience for all of the viewers. The theater can include a three-dimensional, concave shaped screen, defining a central axis that extends perpendicularly from the center point of the concave screen directed toward the seating area. The screen is oriented at a prescribed pitch angle (α) relative to the horizontal. The theater has a seating area having a plurality of seats for viewers and is set up in a stacked arrangement along a planar region and pitched at a prescribed angle (β). The seating area is further confined within a viewing area that is centered on the central axis of the screen.

Panel assemblies for movable partitions include a panel and a protective clip covering at least a portion of a bottom surface of the panel. The panel includes channels defined between lateral edge portions and a back side surface of the panel. Tabs of the protective clip are positioned within corresponding channels. Movable partitions include at least one panel and at least one protective clip, which is assembled with the at least one panel and is coupled to a back side surface of the at least one panel. Tabs of the back portion of the at least one protective clip are inserted at least partially within two opposing channels of the at least one panel. Methods of attaching a protective clip to a panel of a movable partition include positioning tabs extending from longitudinal ends of the back portion of the protective clip within channels of the panel.

A system for transmitting liquids between a stationary core and a rotatable story of a building includes an annular buffer duct having an annular lower duct portion and an upper duct portion in liquid communication with and slidingly engaging the lower duct portion via at least one interface extending along the length of the buffer duct, the lower and upper duct portions being fixed to the stationary core and the rotatable story respectively, or vice versa, so that upon rotation of the story with respect to the core, the lower and upper duct portions rotate relative to each other, the buffer duct internally defining an annular transmission chamber into which the liquid enters through one or more inlet ports formed by the upper duct portion, and from which the liquid exits through one or more outlet ports formed by the lower duct portion, the transmission chamber being at atmospheric pressure.

A system including a plurality of servers mounted in server racks and a cold aisle containment (CAC), the CAC including a roof system, wherein the roof system includes a frame, a plurality of roof panels, wherein each roof panel is connected to the frame and is rotatable with respect to the frame, and a holding mechanism for holding a first roof panel among the plurality of roof panels in a closed position, wherein each roof panel among the plurality of roof panels overlaps at least one adjacent roof panel among the plurality of roof panels, and wherein release of the holding mechanism causes each of the roof panels to rotate to an open position in a cascading manner.
