A modular support frame comprises trusses, purlins transverse to the trusses, and vertical posts supporting the various trusses. A supply of wedges permits flange-type connectors to be joined to complementary connectors throughout the foundation. The trusses are arranged end-to-end in parallel rows, each row comprising at least one pair of trusses or more depending on the desired size of the foundation. Vertical posts are positioned between the ends of each of the trusses within a row and at opposing ends of the row, and each post comprises a pair of flange-type connectors at predetermined heights. Each of the trusses is terminated at either end with a pair of complementary connectors such that adjacent in-line trusses can be mounted to the post between them and the outer pair of trusses can be mounted to the posts terminated the row. Purlins extend perpendicularly between the trusses in adjacent rows to reinforce the frame. To that end, the trusses comprise flange-type connectors and the purlins are terminated at either end with complementary connectors.

An extruded aluminum deck assembly having interlocking decking plates. The decking plates of the interlocking deck assembly have horizontally opposed, interlocking outrigging flanges. The extruded decking components comprise feet depending from a planar top surface.

Improved containment mats and systems of containment mats may include multiple adjoining mats with a top surface and a bottom surface. The multiple mats may provide a modular structural mat system that may be installed at a drill site, with multiple mats placed adjacent to each other with a lap joint connecting adjacent mats. A geotextile may be used to cover the lap joints and a coating applied to the geotextile. Such a system may provide containment of potential spills, a reliable working surface for drilling operations, and relatively fast and less expensive installation.

A device for constructing a stage includes fixed stage parts and movable stage parts. The device includes a set of actuators provided to be physically connected to the movable stage parts and each including a communication module for communicating with a server. The server includes a central communication module for communicating with communication modules of the actuators. A controller is connected to the server and has an operator interface including input means and visualizing means. The controller and server are configured to generate control signals for each actuator on the basis of an input via the input means. Control signals include a safety parameter which indicates a safety level, and an operator can activate different safety levels with different keys. The device is provided to execute control signals with a safety parameter which corresponds to the activated safety level.

The invention provides a pourable composition comprising calcium sulfate hemihydrate; optionally, cement; one or more anionic surfactants selected from alkyl anionic surfactants, alkyl ether anionic surfactants, alkyl aryl anionic surfactants, and combinations thereof; one or more set accelerator additives; and water.

The invention discloses a column-beam connecting assembly capable of being manually assembled, including connecting columns and connecting beams. The connecting column is formed with an arc channel along the axial direction. The arc channel opens to the surface of the column as a groove. A number of pairs of anchor slots are shaped on both sides of the groove, and the anchor slots of the same pair are at the same height. Mounting parts for snapping into the anchor slots are shaped on both sides of the connecting beam. Half T-shaped jointing heads are provided on the outer ends of said mounting pans for connecting to the arc channel, and said jointing heads are either in the shape of a column head matching the arc channel, or in the shape of a hook head. A frame structure assembled by the connecting parts is further disclosed.

A display system is provided and include base panel, a collapsible structure, a structure connector, and a base connector. The collapsible structure includes a pair of modular display panels with a pair of panel connectors that receive one another. The structure connector includes a pair of planar body sections angled with respect to each and connects to the pair of modular display panels. The base connector connects the collapsible structure to the base panel and includes a first planar body section secured to the collapsible structure, a second planar body section positioned adjacent to the first planar body section and secured to the collapsible structure, and a third planar body section positioned adjacent to the first planar body section and the second planar body section and secured to the base panel.

Provided herein are systems and methods to configure an immersive theater environment by moving one or more screens. A movie screen can be provided with one or more actuators coupled to the movie screen, wherein the one or more actuators are configured to move the movie screen in a plurality of directions including, for example, up, down, left, right, back, forward, pitch, roll, and yaw. This system can include a processor coupled to the actuator, wherein the processor is configured to control the movement of the one or more actuators, synchronize cinema content for movement of the movie screen, process cinema content for metadata cues indicating movement of the movie screen, and track positions of the movie screen.
