Abstract: A new and improved helical band actuator (HBA) is provided with a closed conduit upon a radially innermost edge portion of its first elongated fastening band that can accommodate electrical power wiring, as well as fiber optic cables, such that electrical power and computer control data can be transmitted from an electrical power source (EPS) and a central processing unit (CPU) to a powered component supported upon a load-bearing platform being elevated or raised by the new and improved helical band actuator (HBA).

Abstract: Disclosed is a method for converting the area of federally protected wetlands, like those located between the Anacostia River's edge and the boundary of the Washington Metropolitan Area Transit Authority's (WMATA) Anacostia Metrorail Station's property line, into a right-of-way or a specific travel route for the safe passage of hovercraft passenger ferry that is non-destructive of the environmentally sensitive nature of the land used as a right-of-way.

Abstract: Methods and systems are disclosed for monitoring foreign visitors, detecting visa overstays and collecting intelligence, particularly useful in countering international terrorism. The methods and systems employ internet, self-reporting techniques and automated data processing.

Abstract: A bulk unloading station is formed by two elongated modules stacked one on top of the other. Each module has a frame with pillars and when the upper module is stacked on the lower module the pillars on the upper module align with the pillars on the lower module. The modules are sized for shipment by truck or railroad car to the bulk unloading site. The lower module contains fluid transfer equipment. Unloading arms, with fluid conduits connectable to a fluid containing vehicle at one lateral side of the station, are mounted on the upper module. Conduits extending between the lower module and the upper module include removable segments at the juncture of the modules.
