Patent number: 7093909Abstract: There is disclosed herein a visual and thermal shield system that effectively obscures visual indicators and thermal signatures of wheel assemblies of a military vehicle to thereby address longstanding military concerns for vehicle and crew survivability. Our device is spaced outboard from the wheel and tire to maintain an insulating body of air between said shield and the adjacent axle, hub, wheel, and tire. Expeditiously, this invention also affords substantial eclipse of the complete tire profile. If a plurality of wheels exist on said vehicle, then multiple shields of this invention can be used to hinder vehicle identification and potential designation of its military purpose.Type: GrantFiled: June 13, 2003Date of Patent: August 22, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: John G Korpi, Michael J Manceor

Patent number: 6290313Abstract: An improved track end connector for a double-pin track assembly of a tracked vehicle includes a novel connector body, a bolt in the connector body, track pins held by the bolt, and a retainer ring engaging both the body and the bolt. The connector body defines a smooth bore having a relief groove holding the retainer ring. The bolt is inserted through the smooth bore until threads at one end of the bolt engage a second, threaded bore in the connector body. As the bolt screws into the threaded bore, a ramp near the bolt's head expands the retainer ring. As the bolt screws further into the threaded bore, a retention groove on the bolt is clinched by the retainer ring, so that the bolt can not unscrew from the threaded bore. A smooth shank portion of the bolt seats with concave depressions in the track pins, so that the track pins do not escape from the connector body.Type: GrantFiled: May 22, 2000Date of Patent: September 18, 2001Assignee: The United States of America as represented by the Secretary of the ArmyInventor: John G.

Patent number: 5417514Abstract: The application describes an automatically deployable terrain marking dev used to identify off-road safe-travel lanes for vehicles. The marking device has a base comprising a heavy ground engagement dish and a canister set on the ground engagement dish. The canister holds reagents of a foam formation system that can be triggered to form a expanding fluid foam that later hardens. A flexible inelastic base wall forms part of the base and mates to the ground engagement dish to form a sealed compartment containing the canister. A flexible tube frame assembly is communicated with the canister such that the tube frame assembly extends and expands during foam formation. The frame assembly thus has both a compact condition in which at least a part of the assembly folds upon a portion of the base and has an expanded condition in which the assembly is filled with hardened foam.Type: GrantFiled: January 18, 1994Date of Patent: May 23, 1995Assignee: The United States of America as represented by the Secretary of the ArmyInventor: John G.
