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 fire-rated reveal piece and wall assemblies or other assemblies that incorporate the fire-rated reveal piece, in which the reveal piece can include an intumescent or other fire-resistant material strip. The reveal can be attached adjacent to a corner, flange or leg of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement. A fire spray material can be applied over a portion of the reveal piece.

Certain example embodiments relate to an acoustic wall assembly that uses active and/or passive sound reverberation to achieve noise-disruptive functionality, and/or a method of making and/or using the same. With the active approach, sound waves in a given frequency range are detected by a sound masking circuit. Responsive to detection of such sound waves, an air pump (e.g., speaker) is used to pump air in the wall assembly to actively mask the detected sound waves via reverberation and/or the like. The wall assembly may include one, two, or more walls, and the walls may be partial or full walls. With the passive approach, sound waves in a given frequency range are disrupted via features (e.g., holes, slits, etc.) formed in and/or on a wall itself. These techniques may be used together or separately, in different example embodiments.

Fire or sound blocking components are configured to resist the transmission of fire, heat or sound through a gap in a wall assembly. The components can be elongate and have a profile of a consistent cross-sectional shape along the length of the component. In some arrangements, the component is configured to provide fire or sound blocking to a dynamic head-of-wall joint of a wall assembly. In other arrangements, the component is configured to provide fire or sound blocking to a reveal gap within or along an edge of a wall assembly.

An object handling system is described, the system having two substantially perpendicular sets of rails forming a grid above a workspace, the workspace having a plurality of stacked containers. The system includes a series of robotic load handling devices operating on the grid above the workspace, the load handling devices having a body mounted on wheels. The robotic devices can move around the grid under instruction from a computing device, the robotic devices being moved to a point on the grid above a stack of containers and then, using a lifting device, engage and lift a container from the stack. The container is then moved to a point where the objects in the container can be accessed. Modifications to the workspace and grid are described that allow vehicles and roll cages to be used to move stacks from the workspace to a point outside the workspace or from outside the workspace into the workspace.

A roll-up wall system including a frame having a longitudinal axis, a first roller disposed in the frame, a second roller disposed in the frame, and a tube disposed in the frame. A screen may be connected to the tube. The screen may be supported by the first roller and the second roller. Further, the screen may be movable between a first configuration and a second configuration. In the first configuration, the screen is rolled around the tube which is spaced a first distance from the first roller. In the second configuration, the screen forms a barrier adjacent the frame, and the tube is spaced a second distance from the first roller. The second distance may be less than the first distance. Also, the roll-up wall system may be an acoustic barrier which achieves a Sound Transmission Class rating ranging from approximately 31 STC to approximately 53 STC.

A channel strut includes a support member with a first tab and a second tab coupled to the support member. A layer of material, such as foam, is disposed on the channel strut. The support member has a low profile and is configured to be attached to successive wall studs via the first and second tabs. The channel strut is attached to wall studs proximate a location with frequent occurrences of sound and vibration, such as studs behind kitchen cabinets, behind door stops, or behind dresser drawings. The layer of material is configured to provide a damping force to reduce sound and vibration at the installed location.

A framing assembly is disclosed including an acoustic framing arrangement and a plurality of tracks. The acoustic framing arrangement interconnects a top track with a bottom track. The acoustic framing arrangement includes a pair of studs positioned in back-to-back configuration and mechanically joined using a connector. The connector includes a vertical portion that extends between the pair of studs and a base portion that connects to the tracks. When assembled, the acoustic framing arrangement creates space between the pair of studs and positions the studs in an offset configuration to improve wall stud acoustic performance.

A system for reversibly dividing a space is disclosed. Independent panels, with track followers attached to both narrow sides, move along parallel tracks. The panels start in an overhead storage space. The tracks are shaped such that as the panels move from the storage space into the space to be divided, one panel stops higher and the next panel slides down and then under the first panel. These panels preferably form a single-plane divider in the space.

A freestanding booth comprising a plurality of upstanding peripheral walls, a roof and a base upon which the booth stands in use, one of the walls defining an opening that is closed by a door, wherein the base extends along a basal edge of a plurality of the walls but does not extend across the opening.
