A method for preventing collisions in a physical environment for multiple players playing in a virtual reality environment comprises creating a plurality of virtual reality areas with respect to a physical environment. Each of the plurality of players are established as an active player in one of the plurality of virtual reality areas. Each of the plurality of players have an active player avatar mapped into a single virtual reality area of the plurality of virtual reality areas. Each of the plurality of players have a non-active player avatar mapped into each of the plurality of virtual reality areas where the user does not have an active player avatar. The active player avatars and the non-active player avatars are displayed in each of the plurality of virtual reality areas. A single avatar is present in each of the plurality of virtual reality areas for each of the plurality of players.

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.

The present invention relates to using interlocking spacer braces between support members to construct wood and metal framed walls, floors and building trusses. Spacer braces have indentations, extensions, fingers that interlock horizontally, vertically or diagonally between support members. The spacer braces can form diagonal and lateral wall bracing, diagonal and vertical chords within building truss with either horizontally or vertical orientations, beams, hold-downs and shear walls. The spacer braces can be installed between wood or metal framing members.

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 truss bracing system for roof trusses is disclosed. The truss bracing system comprises of a lateral brace and a diagonal brace connected through a pivot point. Both the lateral brace and diagonal brace include a first support member and a second support member where the first support member is angled relative to, and preferably perpendicular to, the second support member. The pivot point allows the diagonal brace to rotate relative to the lateral brace. That is, the truss bracing system has a closed configuration with the diagonal brace resting adjacent and parallel to the lateral brace and an extended configuration with the diagonal brace rotated relative to the lateral brace, such that the diagonal brace is angled relative to the lateral brace. Thus, the truss bracing system provides both lateral and diagonal support to the trusses to which it is attached.

A flooring installation includes at least two floor supports separated from one another by a span distance, the floor supports each having lateral, vertical side walls between which an opening is defined. A bay is defined between the floor supports. A primary subfloor is supported atop and attached to one of the at least two floor supports, the primary subfloor including an overhanging portion overhanging a portion of the bay. A spanning brace is disposed between the at least two floor supports in the bay, the spanning brace engaging on opposing ends the lateral, vertical side walls of the floor supports, one end of the spanning brace extending beneath and spaced from the overhanging portion of the primary subfloor. A recessed subfloor panel is supported atop the spanning brace, the recessed subfloor panel being supported at a lower elevation than the overhanging portion of the adjacent, primary subfloor.

A roof structure adjustable support frame system comprising a plurality of joist rails configured to adjust longitudinally; a plurality of side rails configured to adjust longitudinally between the plurality of joist rails; a plurality of corner rail connectors configured to couple a side rail to a joist rail; and a plurality of adjustable joist rail connectors. The plurality of adjustable joist rail connectors comprise a joist rail attachment configured to removably attach to an end of the joist rail, an extension support member extending longitudinally from a first end of the joist rail attachment, a hook assembly configured to move longitudinally along the extension support member and engage a roof joist to couple the joist rail to the joist; and a movable stop configured to secure the hook assembly against the roof joist.

A method is provided for supporting a recessed subfloor panel in a lowered position relative to an adjacent, primary subfloor, the primary subfloor being supported from beneath by one or more floor supports. The method includes positioning a spanning brace between a pair of floor supports and adjusting a length of the spanning brace such that the spanning brace engages and is supported by lateral, vertical sides of the pair of floor supports. A recessed subfloor panel is supported atop the spanning brace, the recessed subfloor panel being supported at a lower elevation than an adjacent, primary subfloor.

A ground anchor bracket for supporting at least one wall brace at an earth anchor includes a sleeve that has a wall structure surrounding a hollow interior that is configured to receive a stem of the earth anchor. A platform is coupled with an upper portion of the sleeve and has an upper surface that is configured to support a shoe of a wall brace. A post is coupled with the platform and the post protrudes upward from the upper surface of the platform so as to be configured to engage a slot in the shoe of the wall brace. The upper surface of the platform may be substantially planar to simulate a slab floor surface for engaging the shoe of the wall brace.
