Abstract: A distributed hash table infrastructure is described that supports pluggable modules for various services. Transport providers, security providers, and other service providers may be swapped, providing flexibility in supporting various devices and networking configurations.

Abstract: Systems and methods storage of adding a node entry to a routing table of an inquiring node of a data network are disclosed herein. An inquire message is transmitted to a publishing node. The publishing node can be configured to publish a routing entry which can be added by nodes of a network. An acknowledgment response can be received from the publishing node. The roundtrip time elapsed between transmitting the inquire message and receiving the response can be measured by the inquiring node. For all node registration entries in the routing table of the inquiring node a determination of whether the inquiring node is closest in locality to the publishing node than to a node corresponding to each node registration entry can be performed. Such determination can be made based on (a) the roundtrip time between nodes (b) node IP address prefix matching.

Abstract: A pump comprises a stator and at lest one rotor mounted within a housing. The housing comprises a first fluid channel extending about the rotor, the rotor comprising at least one second fluid channel. A first sensor is configured to output a signal indicative of the temperature of the stator, and a second sensor is configured to output a signal indicative of the temperature of the rotor. The temperature of fluid in the channel is controlled depending on the magnitude of signals output from the sensors.
