The disclosure relates to “leg carriage” type trusses, which rely for shipping on elevation by a pair of U-shaped wheeled temporary supports, each having two legs connected by a low horizontal member. The upper ends of the legs are inserted in receiving sleeves installed in the four corners of the truss structure. The clearance between the outer dimensions of the leg and the inner dimensions of the sleeve impact the ease with which legs can be inserted and removed, as well as the lateral “play” in the connection between the leg and truss, which impacts its stability in handling and therefore safety. The disclosure addresses the previous conflict between the two objects by the use of asymmetrical clearances. A relatively relaxed tolerance in the elongated axis of the truss eases insertion and removal. A lesser relative tolerance across the axis of the truss width has no significant impact on leg insertion and removal yet improves stability.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex. The lagoon includes a surf feature and surrounding the lagoon are entertainment, educational, sports, and commercial facilities. The complex has a controlled public access and provides the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon having a surf feature. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

A modular platform system includes a plurality of tiles, legs, beams, and brackets. Peripheries of the tiles and top surfaces of the beams are configured so that the tiles can snap on to the beams, allowing for easy creation of a platform. The beams, legs, and brackets are all configured so that the beams and legs are easily connected together for platform system creation.

Described herein is a multi-purpose portable platform stage for elevating a platform of the stage over a surface on which the stage is placed, that can be converted by a single person individually without assistance from an operational configuration in which one or more persons can stand, move and operate on the platform without the platform collapsing, and in which one or more objects can be placed and used on the platform, by or without such persons, without the platform collapsing, to a portable configuration in which the single person can carry the stage individually without assistance.

A motorized, rotatable treadmill and a system for creating the illusion of user movement while the user is stationary with respect to an environment as the user walks or otherwise moves on an endless track of the treadmill. The user can then travel an unlimited distance in unlimited directions while remaining stationary in physical location. The speed of the treadmill is precisely controlled and/or precisely matched with movement of a camera and a real-world speed of movement of the user and the distance the user travels on the belt to create the illusion of movement of the person being filmed. When the treadmill is provided within an LED virtual film set or green screen set, background imagery is added to further supplement the movement in a selected environment.

The user can then travel an unlimited distance in unlimited directions while remaining stationary in physical location. The speed of the treadmill is precisely controlled and/or precisely matched with movement of a camera and a real-world speed of movement of the user and the distance the user travels on the belt to create the illusion of movement of the person being filmed. When the treadmill is provided within an LED virtual film set or green screen set, background imagery is added to further supplement the movement in a selected environment.

Aspects of the disclosure provide a method, an apparatus and a system for augmented reality. In an example, an apparatus includes an imaging device, processing circuitry and a display device. The imaging device generates a first image of a surrounding environment of the apparatus. The processing circuitry processes first image data of the first image and second image data of a second image to fuse the first image and the second image into a fusion image. The second image includes an object that is not in the surrounding environment. The display device then displays the fusion image.
