Abstract: Described herein are methods and systems for processing gas streams. The gas streams may comprise a methane-containing gas stream, such as an exhaust stream. The systems and methods of the present disclosure may process the methane-containing gas stream using one or more processing units including a biological filtration unit and a thermal oxidizer to generate an output stream which has a lower concentration of methane than the methane-containing gas stream.

Abstract: A multiple unit surface effect vehicle movable through an aquatic environment is provided including connected units and lift fans. The multiple unit surface effect vehicle may further include a coupling system and/or a plurality of skirt portions connecting one of the connected units with another of the connected units. The multiple unit surface effect vehicle includes the connected units connected to form a continuous movable unit movable in an aquatic environment. Each connected unit includes a forced air containment chamber defined within each of the connected units. The forced air containment chambers of each of the connected units are connected to form a continuous pressurized air cushion. The lift fans force air into the forced air containment chamber to pressurize the continuous pressurized air cushion.

Abstract: A ship and associated methods of operation. In an example embodiment, a method of operating a ship includes providing multiple vessels each having a first deck attached to two spaced-apart hull sections. The deck and hull sections define a cavity when the vessel is afloat. A plurality of like coupling mechanisms are provided, each suitable for joining two of the vessels. First and second vessels are joined along starboard and port sides of the deck of the second vessel with one of the coupling mechanisms. Joining is effected by attaching a first of the hull sections on the first vessel to the deck of the second vessel along the port side of the second vessel, and attaching a second of the hull sections on the first vessel to the deck of the second vessel along the starboard side of the second vessel. When coupled to one another the deck of the second vessel is positioned between the first and second hull sections of the first vessel.

Abstract: A head restraint for supporting a user's head with respect to the head rest portion of a seat. The head restraint has a headband strap for placing over the head across the forehead of the user. An anchor band is secured around the head rest portion of the seat. A righthand securement strap is affixed between the strap placed over the head of the user and the anchor band. Similarly, a lefthand strap is affixed between the strap placed over the head of the user and the anchor band.
