摘要： A network system includes a main network implementing a conventional network protocol and a BPD subtree implementing a custom network protocol. The main network comprises a plurality of MPD nodes, the conventional network protocol being configured for MPD nodes. The BPD subtree comprises a plurality of BPD nodes, the custom network protocol being configured for BPD nodes. The custom network protocol defines smaller and simpler subtrees relative to the conventional network protocol. As a result, the custom network protocol defines less complex functions relative to the conventional network protocol, including functions for discovery, messaging, and loop management. A root node of the BPD subtree is connected with an MPD node of the main network and one or more descendant nodes of the BPD subtree. The root node implements the conventional network protocol and the custom network protocol.

摘要： One embodiment of the present invention sets forth a technique for evaluating connections between nodes in a mesh network. The technique includes determining, at a first node, one or more first accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via an established parent node and with receiving messages from the target destination via the established parent node; determining, based on the one or more first accumulated message success rates, that a search for a different parent node should be performed; identifying a plurality of potential parent nodes; computing, for each potential parent node, one or more second accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via the potential parent node and with receiving messages from the target destination via the potential parent node; and based on the second accumulated message success rates, selecting a new parent node from the plurality of potential parent nodes or maintaining the established parent node

摘要： Techniques are provided for ad-hoc authenticated group discovery and data sharing in a mesh network. A group of devices is created without leaving a security gap due to the open communication needed to establish the discovery of the devices forming the group. The group can be authenticated autonomously following network discovery of the devices. Instead of requiring global pre-assigned keys for authentication, the devices in the group are authenticated with signatures and certificate passing thereby providing strong security. The efficiency of data sharing between the devices of the network, such as a mesh network, can also be increased. One or more devices may act as a bridge device between devices of a same group that are not in direct wireless communication with each other to reduce re-broadcasts within the mesh network.

摘要： A metrology device includes a housing, a lower support structure, a PCB coupled to the lower support structure, and a cover coupled to the lower support structure and the housing. The housing supports the cover in three coordinate directions. The lower support structure includes a first pillar that supports the PCB and mechanically couples with the cover. The first pillar causes the PCB to stand off from the lower support structure and causes the cover to stand off from the PCB. The metrology device also includes a second pillar that extends from the lower support structure to a base to cause the lower support structure to stand off from the base. The cover has a non-circle shape, and a cross section of the housing at a same elevation of the housing as an elevation of the cover within the housing is a circle.

摘要： A device and method for sending a configuration setting update to a networked endpoint device are provided. A head-end device in a communication system receives, from an endpoint device, a version audit that includes version information associated with parameter values set at one or more hierarchical level assignments for one or more applications used at the endpoint device, sends, to the endpoint device, a data packet including one or more parameter updates, and receives, from the endpoint device, an error message in response to the endpoint device failing to receive the data packet or an acknowledgement of receipt of the data packet.

摘要： A method for synchronizing time may include receiving initial time information including an initial timestamp from a first device, adjusting a clock of the device with the initial time information, storing the initial time information as an earliest possible time, receiving additional time information, including a second timestamp, from a second device, and evaluating the additional time information. When the evaluated additional time information includes information that is unacceptable, the method may further include adjusting the clock with the second timestamp, and replacing the earliest possible time with the second timestamp. When the evaluated additional time information includes information that is acceptable, the method may further include adjusting the clock with the additional time information, and replacing the earliest possible time with the additional time information. The initial time information and additional time information may be respectively determined based on reconciled time data received from two or more proximate devices.

摘要： An agent, of a distributed intelligence application, generates feature data for a feature. A baseline configuration of parameters is processed, associated with the distributed intelligence application, to determine a first set of parameters. The baseline configuration of parameters and a modified configuration of parameters are processed to determine a second set of parameters. The modified configuration is associated with the distributed intelligence application and indicates a difference from the baseline configuration. A snapshot of dynamic data is processed according to an algorithm using the first set of parameters to determine a first result and using the second set of parameters to determine a second result. The first result and the second result are each provided with a respective indication of the configuration used to generate the result.
