A foldable modular wall system includes a track, one or more stationary wall modules, and one or more foldable wall modules. The foldable wall modules are pivotally and slidably connected to the track such that the foldable wall modules can be selectively moved between a closed confirmation and an open configuration. The foldable modular wall system can also include power hinge jumpers through which electrical wires can nm to power electronic components embedded in or disposed on the foldable wall modules.

A system for pulling wire behind a wall is provided. One embodiment comprises a cylindrical weight defined by an outside diameter and a first length, and a tubular body with a hollow interior defined by an inside diameter that is greater than the outside diameter of the cylindrical weight and a second length that is greater than the first length. A distal end of the tubular body includes a tip configured to penetrate a material that is behind the wall, wherein when oriented in a vertical position behind the wall, and wherein in response to drawing the cylindrical weight upward through the tubular body and then releasing the cylindrical weight, the cylindrical weight travels downward towards the distal end of the tubular body and impacts the tip such that momentum of the downward travelling cylindrical weight is transferred to the tip, thereby driving the tubular body downward through the material.

A track assembly for a rail-mounted component of a vehicle includes a rail cartridge slidably coupled with a track and defines a first slot. A first electrical connector is positioned within the rail cartridge. A connection cartridge defines a channel. The connection cartridge includes first and second sidewalls joined by a bottom wall. A second electrical connector is positioned within the channel and is configured to selectively engage with the first electrical connector. An actuation member is positioned within the channel and is movable between first and second positions. The actuation member is biased to the first position. An actuator is operably coupled with the actuation member to selectively move the actuation member into the second position against the bias.

A power distribution system is disclosed. The power distribution system may include a power skid configured to be installed in a raised floor configuration. The power skid may include a support structure, a floor coupled to the support structure and located on top of the support structure, and one or more enclosing elements disposed along a boundary of the power skid and coupled to the support structure.

A ridge vent may cover a ridge slot in a roof of the structure to provide ventilation. A housing having a length, a width and a height that are sized to fit through a ridge slot of the roof includes a top a top portion proximal to the ridge vent, a bottom portion proximal to the interior of the structure and opposite to the top portion, and at least one wall extending between the top portion and the bottom portion. A securing mechanism is connected to the top portion of the housing to secure the housing within the ridge slot. An electronics bus is positioned within the housing and has an interface that enables operation of modular electronic devices that are removably positioned within the housing.

A cable tray and method of use is provided with the cable tray having a bottom extending along a horizontal panel with two opposite side edges. A pair of side walls attaches to the two opposite side edges. A first positioning rack extends between the side walls. The first positioning rack is orthogonal to the tray bottom and the side walls. A second positioning rack extends between the side walls. The second positioning rack is orthogonal to the tray bottom and the side walls. A first foot bar affixes to an underside of the tray bottom. The first foot bar is vertically aligns with the first positioning rack. A second foot bar affixes to the underside of the tray bottom. The second foot bar vertically aligns with the second positioning rack. Each of the first positioning rack and second positioning rack includes cable support apertures.

A mounting bracket assembly including at least one mount configured to be connected to a structure, a distribution harness configured to mount at least one electrical receptacle, and at least one bracket. The at least one bracket is configured to at least partially extend around the distribution harness and removably connect the distribution harness to the at least one mount.

An automotive bus bar module includes a flat plate-shaped bus bar arranged to extend over electrodes of two adjacent unit batteries of a plurality of linearly arranged unit batteries of a battery assembly to electrically connect the electrodes to each other, a plurality of electric wires arranged to extend along an arrangement direction of the unit batteries, one of the plurality of electric wires being connected to the bus bar and an electric wire holding plate made of resin and arranged to extend over an upper surface of the bus bar, the electric wire holding plate holding the plurality of electric wires in a state of being parallel to each other and arranged planarly such that the plurality of electric wires extend along the arrangement direction of the unit batteries.
