Improvements in a cosmetic equipment shield that provides a cosmetic shield that can cover all of the equipment that can exist on the roof of a building is disclosed. The cosmetic shield convers the roof equipment on one or more sides to improve the visual appearance of the building. The shield allows air movement through the cosmetic shield. The metal strips are staggered, offset or otherwise configured so they prevent viewing through the metal strips or louvers, but allows air flow. The cosmetic equipment shield is secured to the roof to resist most weather conditions from rain to wind, hot temperatures and freezing temperatures. The cosmetic equipment shield is configured for nearly infinite straight walls and can also include angle brackets to change the direction of the shield to 90 degrees or 270 degrees or can be angled slightly in a curved appearance.

A mobile terminal booth with a sound masking function includes a sound absorbing panel which partitions a space as viewed from the above to provide a place where a user of a mobile terminal can have a telephone conversation; a speaker provided to emit sounds to an outside of the mobile terminal booth; and a masking sound generation unit provided to emit a masking sound through the speaker. The harsh-sounding high frequency components of the masking sound which is output from the speaker are attenuated so that the masking sound gives less uncomfortable feeling to persons surrounding the mobile terminal booth.

An exemplary robotic parking device of the present disclosure includes a number of stacks of containers. The stacks being positioned within a frame structure including uprights and a horizontal grid disposed above the stacks. The grid having substantially perpendicular rails on which load handling devices can run. Cars or vehicles are positioned in containers and are moved into and out of the stacks by the robotic handling devices running on the grid. The cars are put into the grid at entry points that may be positioned at points under the stacks.

A composite stud wall panel assembly, which can be used alone as a blast panel or as a module for wall or roof structures, comprises a frame including a plurality of spaced apart metal studs and metal crossbars interconnecting the studs; and a cementitious aggregate panel, one side of the metal studs being embedded in and permanently connected to the panel along the length of the studs.

An enhanced acoustic cell for use in acoustic panels is provided. The provided enhanced acoustic cell has a parabolic-shaped cell floor and a receiving object suspended at its focal point. Components of the enhanced acoustic cell may be easily replicated and installed into a face sheet comprising an array of a plurality of interconnected acoustic cells. The provided acoustic cell, and arrays thereof, may be produced using an additive manufacturing (AM) technology.

A wall panel for a quick assemble wall system may include a first upright post and a second upright post. The wall panel may also include a lower stretcher for connecting the first upright post to the second upright post and an upper stretcher for connecting the first upright post to the second upright post. The wall panel may include at least one frame for placement within the first vertical post, the second vertical post, the lower stretcher, and the upper stretcher. The wall panel may include a first retractable latch located on the at least one frame, the first retractable latch adapted to engage at least one of the first upright post, second upright post, lower stretcher, or upper stretcher. A frame for a quick assemble wall system and a method of assembling a quick assemble wall system are also described.

A robotic parking device is described. The device includes a number of stacks of containers as shown in FIG. 3, the stacks being positioned within a frame structure including uprights and a horizontal grid disposed above the stacks, the grid having substantially perpendicular rails on which load handling devices can run. Cars or vehicles are positioned in containers that are moved in to and out of the stacks by the robotic handling devices running on the grid. The cars are put in to the grid at entry points that may be positioned at points under the stacks.

A system and method for handling shipping containers is described. The container handling system includes a crane, the crane having crane load handling devices. The container handling system includes a conveyance device, the conveyance device including transversal load handling devices. The system provides storage and sortation for storing the containers in a series of stacks disposed beneath a grid, the grid having a series of load handling devices operable thereon. The crane load handling device removes a container from a ship, transports it to transversal load handling device operable on a conveyor. The container is moved on the conveyor to a transfer point where it is collected by a robotic load handling device for transport to the storage and sortation area.

A building element includes a sheet of a rigid material and at least one nonlinear energy sink including a blade with two end parts and a nonlinear spring function intermediate part, a mass fixed to the nonlinear spring function intermediate part of the blade, and a fixing element allowing the two end parts of the blade to be fixed to a solid support in such a way that the nonlinear spring function intermediate part can oscillate about its position of equilibrium or its positions of equilibrium. The nonlinear energy sink is fixed rigidly to the sheet by the fixing element. The building element can be contained in a partition wall. Additionally, such an energy sink or building element can be used for reducing the acoustic transparency of a wall.

A modular, reusable temporary enclosure system is particularly suited for the renovation of buildings having stacked concrete floors supported by steel and/or concrete columns. The system consists of a set of track components, one fastened to the floor, and one fastened to the ceiling. Columns assembled from rigid panels are supported and aligned between these components. The panel edges are connected to one another by an interfacing spline assembly. To ensure that the components can be brought up to the construction site by elevator, individual panels are shorter than the full distance between the floors.
