Abstract: A method of preparing a coated nanoparticle can include decomposing a compound to produce a nanoparticle, oxidizing the nanoparticle to produce an oxidized nanoparticle, and coating the oxidized nanoparticle with a zwitterionic ligand to produce the coated nanoparticle. The coated nanoparticle or the nanoparticle can be used in magnetic resonance imaging.

Abstract: A system for removing undesirable compounds from contaminated air includes a biofilter having a fuzzy logic based controller. A contaminant, such as hydrogen sulfide, is removed from contaminated air by passing the contaminated air through the biofilter.

Abstract: A rescue mission is initiated by deployment of an unmanned water surface vehicle some distance from a location at which an overboard person may be in distress. The water surface vehicle is self-propelled under signal responsive or remote manual control for directionally guided travel toward the distress location, at which a raft stored in the vehicle is ejected and inflated so as to floatingly support thereon the person to be rescued. The deployed raft is then moved from the vehicle for delivery to a rescue location.

Abstract: Equipment to be carried on marine vessels during sea travel, is mounted on the table of a test machine through which shock wave induced motion to be experienced by such equipment during the sea travel is simulated and applied to the equipment carrying table by means of coil springs. Such simulated motion is initiated from a position of the table to which it is displaced and from which it is selectively released through a latch device.

Abstract: An unmanned floating platform is provided for continual surveillance at a station-keeping position at sea. The platform is equipped to dispatch an unmanned vehicle to conduct at least one of observation and rendezvous. The platform includes a hull, first and second hangers, and a liquid storage compartment. The hull has a submerged portion and a floating portion. The first hanger is equipped for stowing, deploying and retrieving a self-propelled unmanned vehicle and is substantially disposed in the floating portion. The second hanger houses equipment for electrical power and on-board functions. The liquid storage compartment supplies fuel to the on-board equipment and to the unmanned vehicle. For static stability, the compartment is disposed in the submerged portion. The platform may also include a superstructure for housing sensor equipment. The superstructure can be disposed above at least one of the first and second hangers. The second hanger may additionally house a tetherable observation aerial post.
