Abstract: There may be situations in which a ship at sea is lost and GPS is not available due to jamming, and neither a position fix nor GPS is available. A system and method allow estimation of ship position (SPOS) using only single radar range measurements and satellite ephemeris data. The same radar can determine ship velocity using radar range rate information.

Abstract: There may be situations in which a ship at sea is lost and GPS is not available due to jamming, and neither a position fix nor GPS is available, or the heading and attitude sensors are degraded. A system and method allow estimating a ship's heading and pitch using radar range measurements, multiple antennas and satellite ephemeris data.

Abstract: A lower electrode dressing tool for a projection welding machine is disclosed. The present invention includes a rotary dresser that refurbishes a projection welding lower electrode. The dresser utilizes the lower electrode's locating pin that stabilizes the dresser as its rotating cutting elements reshape and resurface the lower electrode. This allows for smoother and more accurate performance of the dresser.

Abstract: A lower electrode dressing tool for projection welding machine is disclosed. The dresser includes a rotating cutting mechanism that includes multiple cutting elements. The rotating cutting mechanism has an opening and locating pin in the interior of the mechanism that seats and stabilizes a lower electrode of a projection welding machine against the dresser. While the dresser is in motion, the multiple cutting elements ride against and dress the flat upper surface of the lower electrode.

Abstract: A vehicle moisture barrier comprises a formed barrier film and one or more bend flaps. The bend flaps may be bent along a bend axis formed by a deformation created at a junction line between the bend flap and the barrier film. The distal or free end of the bend flap contacts a trim panel to provide a stiffening force proximate to a raised rib extending from the opposite side of the barrier to promote sealing of the raised rib when a drawn form opposite to the raised rib is not provided to promote such sealing.

Abstract: A dry nutritional meal replacement composition based on the formulation comprising inter alia a protein blend comprising protein concentrate in an amount of about 4.0-86.0% by weight; a blend comprising a cellulose gel and carboxymethyl cellulose gum in an amount of about 2.3-93.0% by weight; a vitamin blend in an amount of about 0.1-12.0% by weight; a mineral blend in an amount of about 0.1-19.0% by weight; a natural or artificial sweetener in an amount of about 0.1-80.0% by weight; dietary fibers other than the cellulose blend in an amount of up to about 66% by weight; and an effective amount of a flavoring agent, alone, or in combination with a coloring agent. The composition, when mixed with an ingestable liquid, such as milk, and shaken at low shear forms a shake, and when mixed at high shear forms a mousse. When ingested, the mixed composition elicits satiety and can be used as a total meal replacement without adverse gastrointestinal disturbances.

Abstract: An accurate and constantly updated attitude instrument is provided for aiaft. The pitch and roll angles are calculated from two sets of velocity measurements, one set being derived from signals received from orbiting navigational satellites and the other set from on-board equipment which determines the aircraft's axial velocities. The on-board equipment may be a Doppler ground-speed sensor or an inertial system using accelerometers, the outputs of which are integrated to derive the axial velocities.

Abstract: An accurate and constantly updated heading reference is provided for movee vehicles, particularly aircraft. The heading is calculated from four velocity measurements, two of which are obtained from signals received from orbiting satellites, and two from on-board equipment which determines the vehicle's along-track and cross-track velocities. The on-board equipment may be a Doppler ground-speed sensor or an inertial velocity sensor using accelerometers, the outputs of which are integrated.
