Patent number: 7162528Abstract: A Collaborator computer collaborative environment (CCE) instantiated by a computer network includes N Collaborator CCE clients and a Collaborator CCE server. Each of the N Collaborator CCE clients generates message objects each including a nested group identifier and an associated privilege level; the Collaborator CCE server filters the generated message objects and routes only those message objects to an Nth Collaborator CCE client that is a member of the respective group having the group identifier and that has a privilege greater than or equal to the associated privilege level. Corresponding software is also described.Type: GrantFiled: October 1, 2002Date of Patent: January 9, 2007Assignee: The United States of America as represented by the Secretary of the NavyInventors: Adam J.

Patent number: 6971300Abstract: A reloadable launcher for use with rocket-propelled projectiles. An inner and outer tube define a concentric tube arrangement with at least one gas flow channel being defined therebetween. A ring is fixedly coupled to a first end of the outer tube that is adjacent to the breech end of the inner tube. The ring defines a keyway and an annular channel that lies between the keyway and the first end of the outer tube. A cap having a concave inner surface terminates in a peripheral edge that defines a key shaped for passage through the keyway of the ring. When the cap's key is aligned with and moved axially through the keyway, the key resides in the annular channel adjacent the first end of the outer tube. A link is hingedly coupled on one end thereof to the ring to permit the cap to be moved such that a projectile can be loaded into the inner tube from the breech end thereof. The link is also rotationally coupled to the cap's central portion such that the cap can be rotated thereabout.Type: GrantFiled: November 25, 2003Date of Patent: December 6, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventor: John F.

Patent number: 6895850Abstract: A pressure-released brake assembly restrains a projectile in a launch tube prior to launch and automatically releases the projectile at launch. A brake assembly housing defines cavities that extend substantially radially out from the projectile when the housing is attached thereto. A brake pad adjoins the housing and has holes formed therethrough with each hole being aligned with one of the housing's cavities. Means are provided for positioning a loose-fitting pin partially in each of the brake pad's holes and partially in a correspondingly aligned housing cavity. When a launch pressure is generated in the projectile's launch tube, the launch pressure acts on each pin via the holes in the brake pad. The launch pressure causes the positioning means to fail and drives each pin out of engagement with the brake pad to effectively uncouple the brake pad from the housing.Type: GrantFiled: September 9, 2003Date of Patent: May 24, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: James Dennis Hagan, James N.

Patent number: 6842242Abstract: A method for controlling both the scattering and absorption of electromagnetic waves. The method is based on prescribing the sizes of the particles that are suspended in a specified medium and a ratio of the refractive indices of the particles and the medium. This method can be used in applications that require maximizing or minimizing scattering of electromagnetic waves. The present method can also be used in applications that require maximizing or minimizing absorption of electromagnetic waves. Further, the invention provides control of backscattering (radar cross section) and, controlling any combination of scattering, absorption and backscattering of electromagnetic waves. Applications for the present method include stealth technology, friend or foe identification, and defensive screening.Type: GrantFiled: November 12, 2003Date of Patent: January 11, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: Nancy L.

Patent number: 6776369Abstract: Guidance of a gliding vehicle is disclosed. A method of the invention allows the range of the glide phase of a gliding vehicle to be maximized, while satisfying final flight path angle and aimpoint requirements. The method controls the time-of-flight of the gliding value to a desired value. The time-of-flight control can correct for winds, off-nominal launch conditions, and rocket motor variations, among other factors. Both time-of-flight control and range and cross-range maximization can be achieved by the inventive method, utilizing a compact closed-loop approach.Type: GrantFiled: November 14, 2003Date of Patent: August 17, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Craig A.

Patent number: 6734558Abstract: A semiconductor device having a barrier film comprising an extremely thin film formed of one or more monolayers each comprised of a two-dimensional array of metal atoms. In one exemplary aspect, the barrier film is used for preventing the diffusion of atoms of another material, such as a copper conductor, into a substrate, such as a semiconducting material or an insulating material. In one mode of making the semiconductor device, the barrier film is formed by depositing a precursor, such as a metal halide (e.g., BaF2), onto the substrate material, and then annealing the resulting film on the substrate material to remove all of the constituents of the temporary heteroepitaxial film except for a monolayer of metal atoms left behind as attached to the surface of the substrate. A conductor, such as copper, deposited onto the barrier film is effectively prevented from diffusing into the substrate material even when the barrier film is only one or several monolayers in thickness.Type: GrantFiled: August 20, 1998Date of Patent: May 11, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Michael F. Stumborg, Francisco Santiago, Tak Kin Chu, Kevin A. Boulais

Patent number: 6622415Abstract: An adjustable sight assembly for attachment to a firearm is provided. A base with a recessed portion has a plate that loosely fits within the recessed portion. A windage adjustment assembly cooperating with the base and a first end of the plate i) effects side-to-side movement of the plate within the recessed portion of the base, and ii) defines a pivotal coupling of the plate to the base at the first end thereof. A second end of the plate moves along an arc when the plate is pivoted about the first end thereof. An elevation adjustment assembly cooperating with the base and the second end of the plate effects elevation of the plate's second end. A sight is pivotally coupled to the plate such that the sight can lie against the plate when not in use and can be rotated approximately 90° to extend vertically from the plate when in use.Type: GrantFiled: July 19, 2002Date of Patent: September 23, 2003Assignee: The United States of America as represented by the Secretary of the NavyInventors: Michael M.

Patent number: 6622632Abstract: The present invention controls the polar ejection angle of fragments in a fragmenting warhead. The warhead's detonators are initiated non-simultaneously to produce corresponding detonation waves in the warhead's explosive material. The detonation waves interact to control the polar ejection angle of fragments formed when the warhead's casing ruptures. Specified times of detonation for each of the detonators can be selected/adjusted after the warhead is deployed.Type: GrantFiled: March 1, 2002Date of Patent: September 23, 2003Assignee: The United States of America as represented by the Secretary of the NavyInventor: Timothy L.
