Abstract: A vehicle includes a heat source, a duct system communicating via openings with the exterior of the vehicle and a chamber housing temperature-sensitive components of the vehicle, the openings of the duct system being arranged such that: motion of the vehicle generates a pressure difference between openings of the duct system so as to drive a cooling airflow through the chamber when the vehicle is in motion; and one opening is higher than another of the openings so as to promote a cooling airflow through the chamber by convection when the vehicle is stationary; the chamber being within sufficient proximity to the heat source so as to be capable of reaching temperatures high enough to effectively drive the convection flow and both said airflows being isolated from any airflow to the heat source.

Abstract: A mechanism for point-to-multipoint file transfer utilizes a pipeline architecture established through a set of networking messages to transfer a file from a source node to a plurality of recipient nodes. Each node in the pipeline can utilize a redundant connection to a next nearest neighbor in the pipeline to decrease the time required to recover from a node failure.

Abstract: A peer to peer discovery mechanism based on the ubiquitous TCP/IP and UDP/IP standards requires no global network configuration to allow the addition and removal of peers from the network. The resulting network architecture is scalable to a large number of processors and together with an automated Peer Voting mechanism which elects a “Prime” Peer at runtime provides a platform for use with distributed computing applications.
