A system, comprising: a storage workspace including a first framework defined by a series of first uprights, the first uprights supporting a grid of two substantially perpendicular sets of rails; and a plurality of containers for storing objects, wherein the plurality of containers are arranged in stacks, each stack of containers is located underneath a grid space in the workspace; and a grid extension including a continuation of the two substantially perpendicular sets of rails, and wherein the plurality of containers can be moved by one or more load handling devices between the storage workspace and an area beneath the grid extension, wherein the area beneath the grid extension is configured for positioning a roll cage such that containers can be placed or removed from the roll cage.

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.

Foam wall structures and methods for making them are described. The wall structures include a frame, a sheet metal sheathing overlying a front surface of the frame, a foam panel overlying the sheet metal sheathing, and a foam layer disposed in a cavity defined by the frame and the sheet metal sheathing. Buildings that include such wall structures are also described.

A cubicle topper includes a rectangular body including a bottom side configured to extend along a top surface of a cubicle wall, a top side parallel to and opposite the bottom side, two short sides that are perpendicular to the bottom and top sides and opposite to each other, and a plurality of body slots formed in the bottom side, and a plurality of legs configured to connect the rectangular body to the cubicle wall, each of the legs including: a body connector piece including a leg slot configured to slide into a respective body slot to thereby connect the leg to the rectangular body, and a cubicle gripper piece including two protruding members configured to grip opposite side surfaces of the cubicle wall and a flat inner surface formed between the two protruding members, the flat inner surface configured to rest on the top surface.

A sealing profile can be used for an edge joint formed between a floor and adjacent cladding of drywall. The sealing profile has a base body for sealing the edge joint. The base body has an upper portion close to the cladding and an opposite bottom portion. The upper portion has an upper side which forms a support for the cladding. The sealing profile also has a lateral fastening portion running towards the base body for fastening the sealing profile to a lateral holding rail of the drywall. The fastening portion is only firmly connected to the base body via the bottom portion. The base body also has a side surface which is directly opposite the fastening portion and which is not connected to the opposite region of the fastening portion. Drywall can contain such a sealing profile.

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 vehicle for use with an object handling system, the object handling system including two substantially perpendicular sets of rails forming a first grid, a plurality of first uprights supporting the first grid, a plurality of containers arranged in stacks, each stack being located underneath the first grid, one or more robotic load handling devices configured to drive on top of the rails of the first grid, the one or more load handling devices including means for removing or replacing at least one container from the stacks. The vehicle includes two substantially perpendicular sets of rails forming a second grid substantially at the top of the vehicle above a storage space for carrying containers. The second grid interfaces with the first grid to allow the one or more load handling devices to drive from the rails of the first grid onto the rails of the second grid.

A storage system is described where goods are stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked out. Each container may be provided with connectors having a push fit male connector located at a top edge of the container and a female connector at a bottom edge of the container. Adjacent containers in a stack can be linked by routing means, which form moldings on each container. The connectors can also have spring-loaded contacts. The provision of these services within individual containers rather than across the system as a whole, allows for flexibility in storage whilst reducing cost and inefficiency.

A noise reduction apparatus can include a frame and multiple spaced apart panels positioned adjacent to each other. Each of the panels or only one of the spaced apart panel elements may have holes therein to receive acoustic waves for absorbing the waves between the panels. The panels can be attached to a frame or other connection structure so that the arrangement of panels can be hung over a work space or positioned in a work space (e.g. in a wall, formed as a partition or wall, included as part of shelving, etc.). The panels can also be incorporated into a light fixture that may hang from a ceiling or be attached to some other type of support (e.g. a table, a base, etc.). The panels can be composed of glass, wood, or other type of material.

Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.
