Abstract: A method serving as a catalyst and tool for improving the fundamental processes vital to a community by applying a quantitative, interlaced, simultaneous, multi-disciplinary, systems engineering approach to improve and maximize achievement of goals and processes occurring within a city or greater extended community, such as, a large watershed area. The method involves a specifically designed facility, a computer-based mathematical model, and an exemplary methodology for public participation based on the mathematical relationship and interdependencies of the educational activity, economic development, ecological preservation, environmental issues, research activity, and entertainment and recreation activity of the community.

Abstract: A non-circular, mechanically variable optical attenuator using a pair of specially constructed polarizing elements with means enabling a gradual transition from un-crossed polarization vector fields to crossed polarization vector fields using a linear motion with respect to one another. The polarizing elements whose polarization axis varies with spatial position on the element have a polarization vector field that is a function of position on the element. Specifically, the two polarizing elements have a defined orientation of polarization axes or vectors on the polarization vector fields that vary with spatial location on the polarizing element such that when aligned light passes, and when the polarization axes are crossed, light is attenuated. The present attenuator has a practical application for dimmable mirrors or windows by providing a variable optical attenuator that is purely mechanical and non-circular in shape.

Abstract: A truck bed organizer comprising two base sides, a rear base end, and a front cab base end. Each base side has a base side rod and two base side legs ending in base side feet. The rear base end has a rear base end rod and two rear base end legs ending in rear base end feet. The front cab base end has a front cab base end rod and two front cab base end legs ending in front cab base end feet. The base side rods, rear base end rod, and front cab base end rod form a substantially rectangular shape upon which an elevated flat platform is optionally attached. A base brace optionally provides structural support as desired. An alternative embodiment of the truck bed organizer comprises an elevated flat platform, a means for positioning the platform, and a substantially empty storage cavity below the platform.

Abstract: A method for making fluid elasticity measurements using an extensional viscometer (100) is disclosed, where stress is not directly measured but is inferred from an accurate measurement of the change in the rate of flow of a liquid during passage through a vertical capillary (104). The flow rate changes when the liquid jet, also called the liquid filament, leaving a first capillary (104), is stretched by the application of vacuum forces. Steady flow is established almost instantly by using a constant liquid head (102, 118) above the capillary, and the flow rate is determined by timing the interval for liquid to drain between two marks (110, 112) on the liquid reservoir surface. Extensional viscosity can be calculated as a ratio of the tensile stress and stretch rate of the liquid at different axial positions.

Abstract: An apparatus including first and second sections of a sanding block slidably interconnected and adapted for use with a continuous belt, and a resilient member interposed between the first section and second sections such that the resilient member both selectively repels the first and second sections one from the other while securing the first and second sections in a desired position relative to one another. The resilient member is rotatably connected to the first section of the sanding block such that the resilient member moves between alternate rotational positions. The resilient member produces variable pressure on the second section of sanding block depending on the rotational position of the resilient member. The resilient member includes a lever for securing the second section of sanding block in a position relative to the first section of sanding block.

Abstract: A self interlocking block system wherein blocks with one or more apertures are interconnected by inserting a hollow peg through the aligned apertures of two vertically adjacent blocks such that a portion of the hollow peg extends into the aperture of the top block and a portion of the hollow peg extends into the aperture of the bottom block, resulting in a vertical shaft extending from the top row of blocks through the bottom row of blocks to the base surface. The vertical shafts may be filled with one or more vertical support bars and/or filler material to provide additional support.

Abstract: A system for authorizing vehicle and passenger entry into a secure area while the vehicle is moving is disclosed. The vehicle passenger authorization system verifies the identity of the vehicle and its occupants while the vehicle is moving, thereby eliminating the need for the vehicle to stop as it approaches a secure area. Vehicle imaging technology is used to identify the vehicle. Biometric technology is used to confirm the identity of the occupants of the vehicle. By combining the biometric information of the occupants with the vehicle identification, an efficient and safe means for automatically controlling the flow of traffic into secured areas is disclosed.

Abstract: A conveyor belt cleaning system being a torsion blade holder assembly having a mounting sub-assembly and a blade support sub-assembly. The mounting sub-assembly has a first hollow member and a second member situated at least partially therein with torsion elements in the plurality of spaces or cavities between the first hollow member and the second member. The blade support sub-assembly, in which a scraper blade is secured, is attached to the second member such that when the scraper blade meets resistance while scraping the surface of a conveyor belt, the torsion elements are compressed and the blade support sub-assembly with the scraper blade rotates away from the conveyor belt.

Abstract: A fireplace including a fire box having a means for producing flames, a trough positioned in front of or around the fire box, and a hood positioned above the fire box and extending out from the fireplace beyond a front opening in the fire box. Positioned in the trough is a plumbing assembly having a pump and piping for transporting water from the trough upward and through an opening in the hood positioned above the fire box. The hood extends outward beyond the fire box such that water will fall freely in front of the fire box containing the flames and into the trough. One or more nozzles may be connected to the piping near one or more openings in the hood to adjust the trajectory of the water as it falls from the hood.

Abstract: A fluid drive conversion system having a plurality of flat foils rotatably connected to a vertical shaft such that the foils are generally vertical in position, pivot about a vertical axis, are a predefined distance, at least about one quarter of the width of a foil, from the vertical shaft thereby creating a central space. In operation, fluid flows through the central space and simultaneously pushes the back side of at least one foil while pushing the front side of one or more remaining foils, resulting in all of the foils rotating about the vertical shaft and contributing to the generation of usable energy. A wing is pivotally connected to the distal end of each radial arm and a bottom radial arm wherein each wing is in a general vertical orientation. The fluid drive conversion system employs either a conventional gear system, a conventional pulley system, or an electrical generation assembly using magnets, coils, and a means for harnessing an electrical current.

The first end of the main container is concave in shape and adapted to correspond to the generally circular shape of the connector container. A shielding wall is formed by interconnecting a connector container of a first modular wall component into a first end of a second modular wall component. The main container and connector container are hollow and are adapted to be filled with a filler material.
