Embodiments of the invention relate to structural panel systems, and in particular in-frame fluted panel systems. The in-frame fluted panel systems allow for improved strength and/or ductility within a reduced wall thickness by installing the fluted panels within the framing of the support members in various configurations. The in-frame fluted panel systems further allows for easier construction and lower costs than conventional systems that have fluted panels located outside of the support members.

A novel system and related methods for sequentially deploying, in automated or semi-automated fashion, a strip of a plurality of truss bays with integral solar panels from a moving carrier onto a surface being traversed, resulting in a long, contiguous truss structure laid upon on the surface. The solar panels are angled at a predetermined orientation for solar operation at the deployment location. The carrier is easily and quickly reloaded with another set of truss bays for repeated deployment of a series of strips of solar truss structures in a solar array. The solar array thus is constructed in substantially less time and with substantially less labor that conventional support racking in the filed using prior art piece-wise assembly operations.

A support column extends in a longitudinal dimension and includes a plurality of outer hollow longitudinal structures. Each longitudinal structure defines an interior passage extending along a length of the longitudinal structure. The support column includes a plurality of inner members. The plurality of outer hollow longitudinal structures are aligned end-to-end along a single axis. The interior passages of the plurality of outer hollow longitudinal structures cooperate to define an interior passage of the support column. The inner members are aligned end-to-end along the single axis within the interior passage of the support column so that opposed longitudinal ends of each of the inner members extend to respective longitudinal ends of each adjacent inner member. At least one end of at least one inner member is longitudinally offset from every longitudinal end of the plurality of outer hollow longitudinal structures.

Device, systems, and methods for boom deployment and/or boom stowage are provided in accordance with various embodiments. Some embodiments may facilitate root control of a boom utilizing a variety of tools and techniques. Some embodiments may facilitate boom tip control. Some embodiments may include a boom and a boom spool. Some embodiments include one or more devices that may include: one or more compliant components, one or more boom spreaders, one or more stabilizing tabs, one or more spool locks, one or more boom tip guides, one or more root clamps, and/or a single consolidation roller. Some embodiments include methods that may utilize one or more of the noted devices.

A flooring system is provided comprising a plurality of (identical) floor panels, which are mechanically connectable to each other along at least one pair of adjacent first and second opposite joint edges. The panels comprise locking elements for connecting said panels in both horizontal and vertical direction. In order to consider the often occurring situation that in panels—especially when stored under changing external conditions, especially changing humidity—might warp, the (vertical) locking element in the panels is constructed with a (slight) play, so that in the event that two panels have slightly different warp nevertheless can easily and reliably be mechanically connected with each other omitting the need to exert an excess of force to fit the panels.

Various embodiments provide for bistable collapsible tubular mast (Bi-CTM) booms. Various embodiments provide CTM booms that may be bistable in nature, thereby achieving intrinsic benefits bistability may bring. Bistability may be achieved in various embodiments through specific combinations of the thin-shell cross-section geometry and the composite laminate selected for each thin-shell segment Additionally, in various embodiments, the thin-shell geometry of each boom half may be different. Various embodiments may include combinations of circular, ellipsoidal, or parabolic segments that form each shell.

Construction unit (1) for building up a frame (2), wherein the frame (2) comprises at least two girders (3a, 3b) and multiple uprights (4), wherein the construction unit (1) comprises a first construction profile (4), a second construction profile (5) and a third construction profile (6), wherein the first construction profile (4) is provided to serve as an upright (4) and the second and the third construction profile (5, 6) are each provided to be part of a respective girder (3a, 3b), wherein each construction unit (1) is provided to form only one upright (4) of a frame (2) and that multiple such construction units (1) are provided to be successively interconnected so that the first construction profiles (4) of successively construction units (1) extend at a distance from one another.

An adjustable header assembly includes a first piece of material and a second piece of material and at least one bracket. The first piece of material has a fixed length and the second piece of material has an adjustable length. In operation, the length of the second piece of material is adjusted until the second piece of material is proximate wall studs. The second piece of material is then coupled to the studs and the at least one bracket is coupled to the first and second pieces of material.

A deck framing system includes a perimeter support member that has a joist support wall and a web wall extending perpendicularly from the joist support wall and an overhang wall extending perpendicularly from the web wall. First and second joist support brackets include a joist support portion and a pair of attachment wings, where each one of the pair of attachment wings contacting the web wall of the perimeter support member. First and second joists each include a deck support wall and a lower wall. The deck support walls of the first and second joists are disposed between the overhang wall and the joist support portions, and the lower walls are disposed between the joist support portions and the joist support wall.
