Abstract: A device which can be fixed to the edge of a panel, for example a sound-absorbing panel formed by heat-bonded synthetic fibers, is disclosed. The device includes a body with a longitudinal through-hole and two walls which define a cavity for enclosing the edge of the panel. The through-hole communicates with the cavity. The through-hole is configured to guide a threaded element (screw or the like) towards the cavity so that the threaded element engages at least with the edge of the panel so that it expands towards the walls of the cavity and is firmly retained by them.

Abstract: An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.

A power supply is coupled to the box and the power supply selectively supplies power to an extrinsic electronic device.

Abstract: A beam-receiving masonry unit bears an outdoor condenser component of a split air conditioning system. The masonry unit generally includes first and second faces each having at least one opening defined by one or more structurally supportive edges. The first face, the second face, and the space between them are sized to incorporate the unit into a block wall or foundation. The openings are positioned to receive a condenser support beam, and the structurally supportive edges in the faces bear the condenser support beam. The unit resists rotation of the beam after the unit is incorporated into a block wall or foundation. A fill opening allows cementitious fill to enter into the unit to bond the unit to a block wall or foundation.

Abstract: A pushing-out apparatus for an extendible mast includes a mast storing unit, a mast pushing-out unit and a mast pushing-out driving unit. The storing unit stores an extendible mast including stages of foldable trusses in a state that the stages are folded. The pushing-out unit is stored in the storing unit around the stage-folded mast stored in the storing unit. The driving unit moves the pushing-out unit to a projecting position in an outside of the storing unit while the stages of the mast are folded, sequentially extend out the folded stages of the mast stored in the storing unit by the pushing-out unit from the storing unit and push out the extended stages from the pushing-out unit of the projecting position in a side of the pushing-out unit opposing to the storing unit.

Abstract: Photovoltaic mounting systems and coupling assemblies for mounting photovoltaic modules are provided. The mounting systems may include short extruded base members that are mounted onto the supporting surface at approximate locations on the supporting surface, and coupling assemblies that may slide along the length of the base members during installation and be locked at particular positions on the length of the base members. The coupling assemblies may be coupled to connectors that in turn couple to two photovoltaic modules. In operation, the installer may first determine approximate locations on which to mount the base members and mount all required base members, and then, place the coupling assemblies at desired locations, lock the coupling assemblies at the desired locations, position the photovoltaic modules in the connectors of the coupling assemblies, and move to the next set of coupling assemblies.

Abstract: A reconfigurable modular partition system having a plurality of different types of interchangeable (wall or ceiling) modules with different types of compatible connection components, each connection component being configured to align with another connection component at an interface to form an interface connection (e.g., channel) for securing the connection components together with one or more universal connection interface members. The interface is configured for on-demand reconfiguration without laborious alteration to aspects of the partition system, modules, and components thereof. Reconfiguration of modules is facilitated by removing the universal connection interface member from the channel, thereby releasing the attachment mechanism and allowing rearrangement of the module(s). Replacement of the universal connection interface member secures the reconfigured modules in place in the rearranged partition system.

Abstract: The expansive soil resistant foundation system includes a foundation frame having footings forming a grid pattern. The grid pattern contains a plurality of spaces within the pattern. Each space defines a main swell duct. Each main swell duct may be provided with one or more sub-swell ducts. The swell ducts permit free expansion and contraction of the expansive soil. A vent extends from each swell duct to expel trapped air. A drainage system is distributed throughout the foundation frame to eliminate accumulation of underground water. The swell ducts, vents, and the drainage system alleviate potential pressures that can be exerted on the foundation from the expansion and contraction of the expansive soil, which can lead to cracks and structural failure.
