Abstract: Augmented reality apparatus and methods of use are provided with secure persistent digital content linked to three-dimensional location coordinates. More specifically, the present method links a physical location with digital content to enable a user interface with augmented reality that combines aspects of the physical area with a three-dimensional location specific digital content. According to the present method, digital content remains persistent with a location even if visual aspects of the location change.

Abstract: Apparatus and methods of artificial intelligent based provision of digital content where and when the digital content is needed based upon where an agent is located and a purpose for accessing the content. A location of a user seeking to access the digital content may be used that enables access to the content. Persistent digital content is linked to location coordinates. A physical onsite location may be linked with digital content to enable provision of a user interface with augmented reality that combines aspects of the physical area with location specific digital content. In addition, access to digital content may be limited to users in defined access areas.

Abstract: Apparatus and methods of artificial intelligent based provision of digital content where and when the digital content is needed based upon where a user is located and a purpose for accessing the content as well as credentials of a user seeking to access the digital content. Persistent digital content is linked to location coordinates. More specifically, the present invention links a physical onsite location with digital content to enable a user interface with augmented reality that combines aspects of the physical area with location specific digital content. In addition, access to digital content may be limited to users in defined access areas.

Abstract: A method of providing a suspended ceiling in a storage tank involves building a deck on the floor of the storage tank and raising it into place by using an external hoist mechanism. The hoist mechanism is connected to the deck by cutting holes in the roof of the tank and feeding cables through the holes. The cables are attached to a series of extenders, such as metal bars, that are fixed to lift points on the deck. The extenders are long enough so that, once the ceiling is raised to its final position, portions of the extenders project into the holes in the roof. The ceiling is then fixed in position by securing the extenders to the roof. After the ceiling is secured in position, the holes in the roof are sealed.

Abstract: A storage structure, particularly for fluids but also useful for storing solids, which in one embodiment includes at least a portion thereof comprising a structural wall having opposing sides, at least one said side having an insulating and protecting built-up layered finish covering which retards heat transfer, the passage of water vapor through the insulation and/or the condensation of water on the one said side, the built-up layered finish covering including a layer of insulation positioned on the one said side of the wall; a solid unitary vapor barrier layer applied to the outer surface of the insulation board as a viscous liquid or paste which hardens into a solid layer; a reinforced stucco basecoat layer applied onto the vapor barrier layer; and a stucco topcoat layer applied onto the stucco basecoat layer.

Abstract: Apparatus and method for depositing a bed of polymeric insulating foam on a horizontal or sloped surface. The apparatus rolls on the surface being insulated and while it moves forward, lateral bands of insulating foam are sequentially and rapidly deposited by spraying a foamable liquid from a nozzle mounted on a carriage reciprocally moving on a track on the apparatus.
