A structural lattice includes a rectangular base defined by four periphery beams, and two non-diagonal beams that divide the rectangular base in four quadrants. The structural lattice further includes a diagonal reinforcement strut system overlaid on the rectangular base and having at least two intersecting sets of diagonal beams forming an open-and-closed cell architecture.

A nacelle of a wind turbine is disclosed. The nacelle comprises a rear frame structure (1) comprising a plurality of truss assemblies (2) being connected to each other at connecting regions (3). At least one of the truss assemblies (2) comprises at least one beam structure (4), the beam structure (4) comprising at 5 least a first beam member (5) and a second beam member (6) being arranged substantially in parallel to each other, thereby defining a longitudinal direction of the beam structure (4). The first (5) and the second (6) beam members are retained to each other by a retaining means (12). The retaining means (12) is configured to enable the first beam member (5) to slide relative to the second 10 beam member (6) along the longitudinal direction, e.g. by means of oblong slits (11) formed in the first beam members (5) and bolts (12) extending through the oblong slits (11) and being attached to the second beam members (6).

A ceiling tile clip includes a top wall, a pair of parallel, spaced side walls that extend downwardly from opposite edges of the top wall and flanges at lower edges of the side walls that extend outwardly. The top wall includes a threaded opening in the center thereof. The ceiling tile clip is configured to be attached to an elongated ceiling grid member by a threaded member that threadedly engages the threaded opening. The elongated ceiling grid member has side surfaces and lower flange portions. When the ceiling tile clip is attached to the elongated ceiling grid member, the top wall of the ceiling tile clip is above the elongated ceiling grid member, the side walls of the ceiling tile clip are alongside the side surfaces of the elongated ceiling grid member and the flanges of the ceiling tile clip are above the flange portions.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

A curved brace is described herein. In some embodiments, the curved brace includes a base plate that has a proximal segment with one or more fastener apertures that is configured to confront a vertical post, a distal segment located distal to the proximal segment that includes one or more fastener apertures that is configured to confront a lateral beam and a curved middle segment located between the proximal and distal segments. A support plate with a curved base as well as a curved free edge may be attached to the base plate. The curved middle segment of the base plate may have an apex facing the apex angle formed at the connection of the lateral beam to the support beam. Methods of using and manufacturing the curved brace are also described.

A structural lattice includes a rectangular base defined by four periphery beams, and two non-diagonal beams that divide the rectangular base in four quadrants. The structural lattice further includes a diagonal reinforcement strut system overlaid on the rectangular base and having at least two intersecting sets of diagonal beams forming an open-and-closed cell architecture.

A structural bracket assembly for a residential or commercial trellis. The structural bracket assembly comprises an aluminum mounting plate securable to a vertical wall having a support member extending outwardly therefrom at an angle and terminating with an end plate. Plywood is fastened to the top and the bottom of the support member. Roofing material is fastened to the upper piece of plywood, and a soffit panel is secured to the lower piece of plywood. A frieze board is secured to the vertical wall beneath the lower piece of plywood to conceal the mounting plate, and a hollow rafter tail is secured to the soffit panel. In one embodiment, the rafter tail is spaced apart from a support bracket by a cross beam.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

A fracture caused by fatigue of a connecting portion positioned at a corner of a reinforcing frame directly secured to a frame is avoided regardless of a relative displacement that occurs in the frame upon disposing the reinforcing frame made of steel, which has an elevational shape surrounding the frame along an inner circumferential surface of the frame and a cross-sectional shape with a flange on a side of the frame, in a structure plane of the frame of a column and a beam of reinforced concrete structure, and joining the reinforcing frame to the inner circumferential surface of the frame. A reinforcing frame is constituted of a column portion along a column of a frame, a beam portion along a beam, and a connecting portion that is joined to the column portion and the beam portion, and connects the column portion to the beam portion. The connecting portion has a flange with a part close to the column portion and the beam portion formed to be shaped along an inner circumferential surface of the frame, and a part of the flange facing a corner of the frame formed into a shape in which a void is formed between the part and the corner of the frame.

A system for generating a virtual reality environment includes a mocap suit having a plurality of sensors for generating at least one mocap suit output responsive to movement of an individual within the mocap suit within the virtual reality environment. At least one virtual reality player headset generates at least one virtual reality headset output responsive to actions of a player within the virtual reality environment. A virtual reality controller receives the at least one mocap suit output and the at least one virtual reality headset output and generates the virtual reality environment for display in the at least one virtual reality player headset. The virtual reality controller selectively generates an avatar associated with the mocap suit responsive to the at least one mocap suit output. The avatar being selectively inserted into the virtual reality world responsive to a first input and selectively removed from the virtual reality environment responsive to a second input.
