Patent number: 5865439Abstract: The invention is a pop-up target system wherein a three-dimensional target is raised by a knee-like action. The target may take the form of a head and torso manufactured in two parts, a front half and a back half, which are hinged at the top of the head portion and may incorporate a thick, relatively massive material which will absorb incoming bullets. The bases of the torso halves are each mounted through hinges to two separate four-wheeled platforms or trucks which are constrained by tracks or guide cables to move linearly to move the bases of the torso halves together in an upright position or apart in a flat horizontal position. The linear relative position of the torso halves is controlled by linear moving means attached to the wheeled platforms or trucks such that at the maximum separation between the torso halves, the two halves of the target lays inclined on a brace so as to be out of horizontal alignment, preferably 5 to 10 degrees out of alignment.Type: GrantFiled: August 14, 1996Date of Patent: February 2, 1999Assignee: The United States of America Army Corps of Engineers as represented by the Secretary of the ArmyInventors: William F.

Patent number: 5702203Abstract: The present invention pertains to a floating breakwater structure in the pe of a "V". This breakwater design allows for a wide range of wave periods, unlike previous floating breakwaters. The construction of the instant invention is that of a suspended curtain which deflects and redirects the waves that are incident thereto rather than absorb or reflect incoming wave energy. This design results in a substantially smaller structure with reduced mooring loads. Moreover, the floating breakwater of the instant invention allows for fast deployment that can be either shipped in sections and assembled on site or assembled in sheltered waters and towed to a site for deployment. The breakwater of the instant invention is intended for temporary coastal operations such as military force projection and sustainment, dredging, coastal civil construction and repair, oil spill recovery, and search/rescue relief missions.Type: GrantFiled: May 18, 1995Date of Patent: December 30, 1997Assignee: U.S. Army Corps of Engineers as represented by the Secretary of the ArmyInventors: Donald T.

Patent number: 5648724Abstract: An apparatus for detecting the presence, location, and extent of the moise in a roof using metallic time-domain reflectomerry (TDR) includes an electrical pulses, a transmission line embedded within the roof and connected with the pulse generator, and a signal analyzer which interprets the electrical pulses transmitted along the transmission line. When the transmission line is exposed to moisture, the dielectric constant of the transmission line changes, thereby causing a portion of the energy of the transmitted pulse to be reflected back toward the source and a portion to pass through to the end of transmission line. The distance from the source and the length of the dielectric discontinuity are determined by analyzing the round-trip travel time of the reflected pulse.Type: GrantFiled: February 8, 1996Date of Patent: July 15, 1997Assignee: U.S. Army Corps of Engineers as represented by the Secretary of the ArmyInventors: Norbert E.

Patent number: 5556230Abstract: The present invention describes a cylindrical armor unit for use in a revent structure, herein referred to as Vatia Stone. These units are shaped for: i) optimal strength, positional stability and durability; ii) interlocking along all major axes; iii) flexible interlocking capability with each other for abrupt transitions in shorelines; and iv) natural aesthetic qualities. These qualities in combination provide a significant improvement over existing structures. The Vatia Stones are uniformly placed over an erosion controlled shoreline surface and have an optimal interlocking capability between individual units for maximum stabilization. Each unit has an upper and lower surface which can be shaped geometrically to fit the natural surroundings, e.g. look like natural stone as one example.Type: GrantFiled: October 19, 1994Date of Patent: September 17, 1996Assignee: U.S. Army Corps of Engineers as represented by the Secretary of the ArmyInventors: George F.

Patent number: 5548115Abstract: A probe device for in-situ detection of contaminants such as petroleum prcts in a subsurface media such as soil. The device comprises an elongated probe housing which is driven into the media. An ultraviolet lamp located in the housing provides excitation energy which is reflected through a UV transparent window in the housing to the media by at least one reflecting element in the housing. The reflecting element allows longitudinal offset of the lamp from the window providing space for high intensity UV lamps. A radiation receiver receives fluorescent radiation emitted from contaminants in the media transmitted through the window and provides a signal for analysis equipment on the surface. A concentrating reflector between the lamp and the housing and a focusing lens between the lamp and the reflecting element collect and focus excitation energy from the lamp.Type: GrantFiled: September 29, 1995Date of Patent: August 20, 1996Assignee: U.S. Army Corps of Engineers as Represented by the Secretary of the ArmyInventors: John H.

Patent number: 5483836Abstract: Disclosed is a device for measuring lateral deformation in an material spmen which includes a generally ring shaped frame member displaced generally perpendicularly to the object being measured. The frame member itself comprises a first and a second generally arc shaped element which abut end to end. At least one spring arm member is fixed at one end on a mounting projection on the first arc shaped element and its movable end abuts a spring receiving projection from the second generally arc shaped element. Strain gauges are fixed to the spring arm member to detect changes in the flexture of the spring arm member resulting from relative movement of the two arc shaped elements which results from lateral deformation of the material specimen. A linear variable differential transformer having a lateral projection is also mounted on one of the arc shaped elements.Type: GrantFiled: October 13, 1994Date of Patent: January 16, 1996Assignee: U.S. Army Corps of Engineers as represented by the Secretary of the ArmyInventor: Stephen Kinnebrew

Patent number: 5442363Abstract: The invention provides a method and apparatus for determining the precise coordinate of a remote roving on-the-fly signal receiver with respect to a reference signal receiver. The reference signal receiver is usually fixed to the Earth's surface but the instant invention's method allows for movement of the reference signal receiver without performance degradation. The reference receiver and remote roving receiver track four or more satellites so that single difference code and carrier ranges between the receivers can be formed. The method can work with just L1 signal alone, the preferred method uses at least one code range (e.g., C/A code) and two carrier ranges (e.g., L1 and L2) with full wavelength L2--squared implementation addition code ranges if available for use. This method allows for initialization of carrier integer ambiguities whether reference or remote receiver are fixed or moving relative to each other and a robust procedure for determining integer ambiguities.Type: GrantFiled: August 4, 1994Date of Patent: August 15, 1995Assignee: U.S. Army Corps of Engineers as represented by the Secretary of the ArmyInventor: Benjamin W.

Patent number: 5358057Abstract: An improved module and assembly for sampling liquids and gases within the ground is characterized by module housings containing sampling cavities having lateral openings to the exterior of the housings. Within each lateral opening a removable insert and piston assembly is provided. The piston is displaceable between open and closed positions within the insert in response to changes in pressure from pressure and vacuum sources. When in the closed position, the piston and insert are flush with the exterior of the housing to prevent contaminants from accumulating at the opening. When the module is inserted to a desired depth in the ground, the piston is displaced to the open position and samples from the soil at the desired depth enter the sampling cavity.Type: GrantFiled: November 10, 1993Date of Patent: October 25, 1994Assignee: U.S. Army Corps of Engineers as represented by the Secretary of the ArmyInventors: John F.
