摘要： In one embodiment, a centralized network management server (NMS) determines a network state of a low power and lossy network (LLN) based on resource utilization due to traffic in the LLN. The NMS also determines an admission state based on the network state, and admission control (network-wide and/or localized control) based on the admission state. As such, the centralized NMS can then administer the admission control for all nodes in the LLN, where network-wide control comprises a single control command to all nodes in the LLN, and the nodes direct admission based on the control command, and where localized control comprises a request-response exchange between the nodes and the centralized NMS, and the NMS directs admission on a per-request basis.

摘要： In an example embodiment, there is described herein an apparatus comprising an interface and logic operable receive data from a device via the interface. The logic is operable to estimate a location of the device based on data received via the interface based on a first (e.g. default) location classification. The logic is further operable to estimate a location of the device based on data received via the interface based on a second location classification responsive to a predefined trigger.

摘要： A pressure relief valve includes a housing including an inlet chamber adapted to be in communication with an outlet of a pump and an outlet chamber adapted to be in communication with a pump inlet. The housing includes a bore having a first end in communication with the inlet chamber and a main spill aperture in communication with the bore and the outlet chamber. A piston includes an orifice and an axially spaced apart aperture. The piston is axially moveable within the bore between a first position whereat the piston seals the inlet chamber from the outlet chamber, a second position whereat the inlet and outlet chambers are in fluid communication with one another via only the orifice, and a third position whereat the inlet and outlet chambers are in fluid communication with one another via the orifice and the aperture. A spring biases the piston toward the first position.
