Patent number: 6414606Abstract: Adding a quantity of metallic shot or particles of other materials having a high dielectric constant to the thermoplastic paint in the mixing pot of ordinary roadway marker fixation equipment, which extrudes the paint and applies same to the roadway surface, enhances the MMW radiometric visibility of the marker without adverse effect to the affixation equipment. Vehicles containing MMW radiometers directed down toward the roadway surface moves along the roadway surface is able to automatically sense microwave/millimeter wave energy from a marker in the vehicles path. In one system, the sensed energy is used in conjunction with other apparatus to assist to guide the vehicle within a traffic lane. In another system, the sensed energy is decoded and displayed as pertinent information for the vehicle's driver.Type: GrantFiled: August 11, 2000Date of Patent: July 2, 2002Assignee: TRW Inc.Inventors: M. Larry Yujiri, Bruce I. Hauss, Bill H. Quon, James E. Eninger

Patent number: 6195057Abstract: A submarine antenna assembly comprises a tubular body having a removable end cap, a mast stowable in the body and extendible therefrom and having elements mounted thereon, a penetrator stowable in the body and movable therefrom by the mast upon removal of the end cap, the penetrator being adapted to bore through an ice layer, and an inflatable ring stowable in the body and movable therefrom by the mast upon the removal of the end cap. First and second capsules are in the body for retaining and releasing gas, the first capsule being adapted upon opening thereof to pressurize the body to blow off the end cap to permit movement of the mast, the ring, and penetrator out of body, and the second capsule being adapted to inflate the ring to hold the penetrator in engagement with an undersurface of the ice layer. An electronics assembly is disposed in the body and includes message retention and transmitting means in communication with the mast, and timer means in communication with the capsules.Type: GrantFiled: August 20, 1999Date of Patent: February 27, 2001Assignee: The United States of America as represented by the Secretary of the NavyInventors: Jeffrey S. Kornblith, James E. Eninger, James M. Zamel, Samuel Kuo Kan

Patent number: 5400688Abstract: A missile defense system generates a change in density in the air path of a missile. The density change is created by a high-pressure water system which can be generated by a water jet or a body of water explosively created from a water surface. When operating against a waterborne missile, the density of the water medium is changed. The change in density creates an effective barrier against an incoming missile.Type: GrantFiled: August 24, 1993Date of Patent: March 28, 1995Assignee: TRW Inc.Inventors: James E. Eninger, Peter D. Lohn, H. Wilhelm Behrens

Patent number: 5319376Abstract: An improved ice penetrating arctic buoy for release from a submarine submerged under a layer of ice includes a Global Positioning System navigational processor receiver and/or a Emergency Position Information Radio Beacon and/or surveillance apparatus, an antenna for transmission and/or reception of appropriate RF frequencies, such as Global Positioning System or other R.F. frequencies found in the environment above the ice or EPIRB R.F. frequencies originating in the buoy into the environment above the ice. Convertor means converts navigational information and/or other information outputted from said Global Positioning System receiver into coded corresponding information and an on board transmitter sends such coded information acoustically or optically and/or electrically to the submarine via an underwater data link.Type: GrantFiled: December 1, 1992Date of Patent: June 7, 1994Assignee: TRW Inc.Inventor: James E. Eninger

Patent number: 5246078Abstract: Improved ice penetrator apparatus includes protective apparatus for the thermochemical ice penetrator to prevent an undesired explosive sound producing chemical reaction between water and the material of said ice penetrator, particularly while the penetrator is resident in a buoy tube prior to release. The protective apparatus at least partially covers the thermochemical ice penetrator and forms a unitary assembly therewith. The characteristic of the protective material is such that it is non-reactive to the ice penetrator material, typically lithium and/or a sodium lithium alloy, and to water. The protective apparatus may assume any of a diving bell, clam shell and banana skin structural form.Type: GrantFiled: January 10, 1992Date of Patent: September 21, 1993Assignee: TRW Inc.Inventors: John B. Kryger, James E. Eninger, Lee R. Miller, Lee D. Bergerson, Richard L. Prossen

Patent number: 5116268Abstract: A flotation gimbal for a buoy which comprises a flotation bladder connected o the buoy by a pair of looped risers. The risers are anchored to the buoy by a guide in which the risers are allowed to freely move to maintain even tension on the risers as the position of the flotation bladder is tilted.Type: GrantFiled: June 10, 1991Date of Patent: May 26, 1992Assignee: The United States of America as represented by the Secretary of the NavyInventors: James E. Eninger, James M. Zamel, Richard L. Prossen

Patent number: 4651834Abstract: A thermal ice penetration method and apparatus for melting a hole through ice preferably utilizing thermochemical heating by exothermal reaction between water supplied at least in part by the melting ice and a thermochemical reactant, preferably lithium and/or other alkali metal or alkali metal alloy. A number of ice penetration systems and devices are disclosed which utilize the thermal ice penetration to deploy payloads, such as sensors, transducers, antennas, instruments, weapons, or the like, through polar ice either downwardly from the ice surface into the water below the ice or upwardly from the underside of the ice through the ice surface.Type: GrantFiled: August 9, 1985Date of Patent: March 24, 1987Assignee: TRW Inc.Inventors: James E.
