Abstract: A zirconium polymer composition comprising a zirconium polymer selected from the group consisting of polymeric zirconium oxychloride, polymeric zirconium acetate, and polymeric zirconium nitrate and having metal particles thereon is beneficial to aid in the removal of biological contaminants, such as bacteria, virus, yeast, algae, and amoeba, from fluids, including air and water. In this composition, the metal is selected from the group consisting of aluminum (Al), antimony (Sb), arsenic (As), barium (Ba), silicon (Si), boron (B), copper (Cu), gold (Au), lead (Pb), mercury (Hg), nickel (Ni), silver (Ag), thorium (Th), tin (Sn), zinc (Zn), and mixtures thereof, and the metal particles are about 0.001% by weight to about 30% by weight of the composition. These zirconium polymer compositions are used in methods for removing biological contaminants from fluids.

Abstract: PVC compositions disclosed herein comprise PVC resin, a rare earth compound, and an inorganic flame retardant. These PVC compositions demonstrate an improved flame retardance and have UL94 classification with a sample thickness of about 0.8 mm of V-2 or higher. The rare earth compound can be rare earth hydroxides, hydrated rare earth oxides, and mixtures thereof. The inorganic flame retardant can be antimony trioxide (ATO), magnesium dihydroxide (MDH), aluminum trihydrate (ATH), and mixtures thereof. The combination of the rare earth compound and inorganic flame retardant forms a synergistic partnership.

Abstract: A particulate oxide composition comprising cerium oxide, trivalent dopant, and optional additional metal oxide, other than cerium oxide and trivalent dopant, is beneficial to aid in the removal of biological contaminants, such as bacteria, viruses, fungi, protozoa (e.g., amoebae), yeast and algae. This particulate oxide composition contains more cerium oxide than trivalent dopant and has a unique depth profile in which the average trivalent dopant to Ce ratio at about 0 nm to about 3.5 nm from the surface of the particulate composition is greater than the trivalent dopant to Ce ratio at about 15 nm from the surface of the particulate composition. These trivalent doped cerium oxide compositions can be used to remove these biological contaminants from fluids, including air and water, and from solid surfaces. Also described are methods of using compositions containing these trivalent doped cerium oxide compositions to remove biological contaminants.

Abstract: Embodiments of the invention permit flight paths (current and planned) to be viewed from various orientations to provide improved path and terrain awareness via graphical two-dimensional or three-dimensional perspective display formats. By coupling the flight path information with a terrain database, uncompromising terrain awareness relative to the path and ownship is provided. In addition, missed approaches, path deviations, and any navigational path can be reviewed and rehearsed before performing the actual task. By rehearsing a particular mission, check list items can be reviewed, terrain awareness can be highlighted, and missed approach procedures can be discussed by the flight crew. Further, the use of Controller Pilot Datalink Communications enables data-linked path, flight plan changes, and Air Traffic Control requests to be integrated into the flight display of the present invention.

Abstract: A system for multi-modal cockpit interface during surface operation of an aircraft comprises a head tracking device, a processing element, and a full-color head worn display. The processing element is configured to receive head position information from the head tracking device, to receive current location information of the aircraft, and to render a virtual airport scene corresponding to the head position information and the current aircraft location. The full-color head worn display is configured to receive the virtual airport scene from the processing element and to display the virtual airport scene. The current location information may be received from one of a global positioning system or an inertial navigation system.

Abstract: Methods, apparatus and computer program products can generate light weight but highly realistic and accurate colored models of three-dimensional colored objects. The colored model may be generated from a second plurality of points that define a coarse digital representation of the surface and at least one texture map containing information derived from a first plurality of colored points that define a fine digital representation of the surface. This derivation is achieved by mapping points within the texture map to the fine digital representation of the three-dimensional surface. Colored scan data may be used to construct the fine digital representation as a triangulated surface (i.e., triangulation) using a wrapping operation.

Abstract: A wall ironing ring (8, 11, 14) for use in cooperation with a punch (1) to reduce the thickness of a sidewall of a cup (17) drawn from a laminate of a polyester film and sheet aluminum or sheet aluminum alloy has a frusto conical entry surface (24) to the ring which converges at an angle between 1.degree. and 4.degree. to a central axis perpendicular to the plane of the ring and terminates at a land of short length, measured at said axis; and divergent exit surface extends from said land at an angle in the range from 5.degree. to 15.degree.. The ironing ring may be made from a material having a thermal conductivity greater than 50 W/m.degree.C. used in cooperation with a like ring of smaller land diameter held apart from the first ring by a spacer (7) in which coolant is applied to the cup.
