Abstract: A stainless steel vacuum drink container able to keep liquids at a refrigerated state for a minimum of 5 hrs. The bottle includes a stainless steel double wall vacuum insulated bottle with a freezer component, attached to the lid, and optimally placed in the liquid for the thermal exchange to keep the liquid refrigerated.

Abstract: The topology of a network is represented, or emulated, by a topology engine comprising processing elements interconnected via a connection matrix. Queries representing physical problems of the network are supplied by a host processor to the topology engine, where they are processed in the processing elements in accordance with the topology to produce responses which are returned to the host processor. In particular, the network can be a communications network and the queries can comprise search requests for determining connection paths between devices of the network. The topology engine can use processors with multiple instances so that it is more compact than the communications network that it represents.

Abstract: Method and apparatus for protection of traffic in a mesh network are disclosed. A source node sends duplicate copies of data packets of the protected traffic on physically diverse paths through the network. The data packets include a sequence number for determining their position in the protected traffic. A destination node receives the data packets from the paths, selects the next data packet in the sequence and transfers that packet to a receiving queue, while duplicate packets are discarded, and later packets in the sequence are held in a holding queue for future selection. The method does not require a synchronization function between the paths to perform a switchover in the event of a fault, and therefore the method is simple to implement. The method is also scalable to provide multiple physically diverse paths in order to achieve greater degrees of protection.

Abstract: Failures within a communications network are compensated for by establishing a set of two or more communications paths across the network between a source node and a destination node. At the source node a status of each one of the set of communications paths is maintained, and the data traffic is load-balanced across those ones of the set of communications paths having an operational status. In the event of failure of a physical network resource, a failure notification message is propagated to the source node, which registers a non-operation status of each path traversing the failed resource. Load-balancing of the data traffic continues across the remaining operational paths. Traffic may be prioritized based on service level agreements and quality of service protection guarantees.
