Abstract: A system for automatically increasing a capacity of a virtual space in a virtual world may include a processor and a module operating on the processor for detecting an attempt by an avatar to enter a virtual space in a virtual world. The system may also include another module for determining if an allowable number of avatars is currently in the virtual space. The allowable number of avatars may be determined by at least a capacity of a server that is hosting the virtual space. Another module may be provided for increasing a capacity of the virtual space when the allowable number of avatars is currently in the virtual space. Increasing the capacity of the virtual space may include spawning a replicate new virtual space on a different server in response to the capacity of the server that is hosting the virtual space reaching the allowable number of avatars.

Abstract: A modular air intake duct system for a vehicle including at least on intake duct and an attachment for attaching the intake duct to at least one structural member of the vehicle. The at least one intake duct is adapted to be demountably attached to a load bearing structural member of the vehicle where at least one intake duct itself is adapted to bear substantially no load. The intake duct is modular and has at least one module.

Abstract: An engine nozzle arrangement for an aircraft comprises a nozzle (18) for hot exhaust gases, and a shroud (20) for the stream of hot exhaust gases emerging from the exhaust nozzle. The shroud includes an intake for a boundary layer of air for cooling the stream of exhaust gases.
