Patent number: 7243921Abstract: A method providing a self-dispensing additive for buffering a projectile trapping medium and passivating spent projectiles trapped therein. The additive is a buffering compound formed as blocks of low-density foamed-concrete that self-dispenses the additive when contacted by the fired projectiles. The blocks contain dry components that may include one or more of low-solubility phosphate compounds, low-solubility aluminum compounds, iron compounds, sulfate compounds, and calcium carbonate mixed with a cementing material, water, and an aqueous-based foam in substantially stoichiometric amounts. The aqueous-based foam is added in a quantity sufficient to adjust the density of the block to neutral buoyancy in the projectile-trapping medium. The additive chemically stabilizes the medium while also passivating projectiles, in particular heavy-metal projectiles, trapped in the medium.Type: GrantFiled: July 12, 2006Date of Patent: July 17, 2007Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Steven L.

Patent number: 7214000Abstract: An unobtrusive on-grade barrier. One embodiment comprises a concrete-lined trench over which a biased hinged plate is affixed to an end wall of the trench. The biased hinge holds the free end of the plate against a tab affixed to the other end wall, assuring the plate does not rise above grade. The plate is supported for vehicle passage by a sliding mechanism energized by an actuator controlled by a controller that may be automated or operated by security personnel. The barrier may be configured so that vehicles may approach from either end. Upon authorizing access to the driver, the vehicle is permitted to pass over the supported plate. If the driver is not authorized access, the support is slid out of the way and any vehicle attempting to pass slides into the trench. Embodiments may include means for clearing the trench of a trapped vehicle.Type: GrantFiled: November 3, 2004Date of Patent: May 8, 2007Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Charles P.

Patent number: 7200243Abstract: A method that facilitates identification of features in a scene enables enhanced detail to be displayed. One embodiment incorporates a multi-grid Gibbs-based algorithm to partition sets of endmembers of an image into smaller sets upon which spatial consistency is imposed. At each site within an imaged scene, not necessarily a site entirely within one of the small sets, the parameters of a linear mixture model are estimated based on the small set of endmembers in the partition associated with that site. An, enhanced spectral mixing process (SMP) is then computed. One embodiment employs a simulated annealing method of partitioning hyperspectral imagery, initialized by a supervised classification method to provide spatially smooth class labeling for terrain mapping applications. One estimate of the model is a Gibbs distribution defined over a symmetric spatial neighborhood system that is based on an energy function characterizing spectral disparities in both Euclidean distance and spectral angle.Type: GrantFiled: June 26, 2003Date of Patent: April 3, 2007Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Daniel M.

Patent number: 7194389Abstract: A procedure automatically resolves vertical differences commonly found when merging and combining Digital Elevation Models (DEMs) from different collection and production systems. These systems may employ technologies used in single pass Interferometric Synthetic Aperture Radar (IFSAR), LIght Detection And Ranging (LIDAR), and photogrammetry, as well as DEMs derived from contour based elevation data and GPS point data. This procedure employs sophisticated software checking routines for automatically identifying horizontal and vertical datums used by the differing systems as well as any geoid models employed by them. Normally, all of these sources use different vertical datums and may use different horizontal datums. A preferred embodiment of the present invention automatically recognizes the vertical datums, including those that are associated with the geoid models and the 3-D datums that conventional GIS does not support at present.Type: GrantFiled: March 25, 2003Date of Patent: March 20, 2007Assignee: The United States of America as represented by the Secretary of the ArmyInventor: James J.

Patent number: 7189281Abstract: A second-generation rotating biofilter employing microorganisms in a microbiological film (biofilm) “mineralizes” contaminants, such as VOCs and odoriferous contaminants. Contaminated fluid, such as air from manufacturing processes, is directed radially outward from a perforated pipe through porous foam attached to the pipe. The pipe serves as the axis upon which layers of foam suitable for supporting formation of biofilms are placed. In one embodiment, an octagonal-shaped drum incorporates eight baskets. In each basket, foam is layered outwardly from the pipe in trapezoidal-shaped layers each of approximately 3.8 cm thickness, each layer separated by air gaps of approximately 1.3 cm to prevent clogging. Seven layers in each of eight baskets comprise the octagonal drum. When the drum is sprayed on one side, water soaks the media and it is heavier on that side, thus facilitating rotation of the drum. Further, the biofilms are supplied with moisture and supplemental nutrients as needed.Type: GrantFiled: August 4, 2004Date of Patent: March 13, 2007Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Byung J.

Patent number: 7158240Abstract: Apparatus for determining the thickness of a configuration having flat, parallel surfaces that are transparent, or nearly so, to pre-specified types of energy. Embodiments comprise a mechanism for illuminating a front surface with an energy source and mechanisms for measuring reflections of the illumination from a parallel back surface. The energy is contained in a spectrum of wavelengths, the energy being refracted in components at unique wavelengths, e.g., different colored light bands, and similarly reflected from the back surface. The measuring mechanisms, e.g., spectrometers, determine the relative lateral displacement between two spectral lines in the refracted and reflected beams to enable determination of thickness. Other characteristics of the material of the configuration may be ascertained, e.g., chemical composition is ascertained by measuring the intensity of responses at multiple wavelengths and comparing this to responses of known materials.Type: GrantFiled: June 16, 2004Date of Patent: January 2, 2007Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Charles C.

Patent number: 7141815Abstract: Arrays of optical fibers connected to specially configured electronics, e.g., a phototransistor, an LED, an amplifier, a detector, and display, software and PCMCIA A/D board available on a personal computer, are used to obtain continuous real-time acquisition, processing, and visualization of change in a media occurring in natural environments. Alternatively, many of the individual circuit elements above may be replaced with a power meter. In a specific application, data are collected on the depth of sediment below a body of water. As the sediment depth is changed by an event, the ends of the optical fibers in the array display a different reflection or transmission coefficient indicating that water has replaced sediment or vice versa. By knowing which of the optical fiber ends in the array is indicating the changed reflection or transmission coefficient, scour depth or silt accretion may be estimated. A method of employment of the system is also described.Type: GrantFiled: January 30, 2004Date of Patent: November 28, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Norbert E.

Patent number: 7128498Abstract: In one application for containing and remediating contaminants in sediments, employing a geocomposite eliminates the need for a thick cap or removal and subsequent ex situ treatment of the sediment. A geocomposite with at least one layer of reactive material is placed over the area to be remediated. A layer of available surcharge materials such as sand, gravel, or riprap covers the geocomposite. The weight of the surcharge materials causes pore water to flow from the sediment through the reactive layer or layers. Contaminants may be trapped in this reactive layer or layers. A top or bottom layer, or both a top and bottom layer, may be provided to inhibit incursion from outside the sediment layer, while permitting appropriate flow direction of pore water into the reactive layer or layers.Type: GrantFiled: August 2, 2005Date of Patent: October 31, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Thomas Clair Sheahan, Akram N.

Patent number: 7058544Abstract: A knowledge-based condition survey inspection (KBSCI) framework and procedure for use with an engineering management system (EMS) that tailors types of condition survey inspections (CSIs) and inspection intervals to empirically-established life cycles of component-sections. Embodiments of the invention facilitate proactive life cycle management, scheduling appropriate types of CSIs only when needed. The frequency and type of inspection is tailored to items important to a facility manager, such as the importance to the operation of individual component-sections and their individual life cycle, not the overall life cycle of a system or facility. Further, additional useful information is available from the data collected to maintain embodiments of the KBCSI framework so that meaningful “What-If” analysis may be performed in support of decision makers. By tailoring CSIs to needs rather than an arbitrary inspection schedule designed to only catch deficiencies, significant life cycle cost savings are realized.Type: GrantFiled: July 9, 2004Date of Patent: June 6, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Donald R. Uzarski, Michael N. Grussing

Patent number: 6990360Abstract: A system, and method of its use, provides for detecting patterns that exist within a geographic area due to the presence of an orderly array of objects. In a preferred embodiment, the system uses an irregular array of transceivers to illuminate an area suspected of containing a minefield. Typically, these minefields are arranged in an orderly arrangement. Exploiting the Bragg Effect, the transceivers, each configured as a surface wave radar, illuminate an area with RF energy that is scanned in carrier frequency within the HF band (3–30 MHz) at a pre-specified interval. At the frequency that corresponds to the Bragg Effect, a significantly increased signal level occurs that indicates the presence of a pattern such as one might expect from reflections from numerous objects arranged orderly. By processing these returns judiciously, the minefield's size, location, perimeter, and even the location of individual mines may be determined.Type: GrantFiled: November 2, 2001Date of Patent: January 24, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Henry Berger, Edmundo Simental
