    Abstract: A wireless mesh network is configured to manage a power grid. Each node within the wireless mesh network is configured to detect and classify voltage fluctuations in power supplied by an upstream transformer coupled to the power grid. When a given node detects a particular type of fluctuation (i.e., an “event”), the node generates a timestamped event classification that reflects the type of event and a time when the event occurred. A server configured to manage the wireless mesh network receives timestamped event classifications from each node within the wireless mesh network and then performs a time correlation with the received timestamped event classifications to determine which nodes detected similar events. When two or more nodes detected the same event at similar times, the server determines that those nodes are coupled to the same transformer.

    Abstract: One embodiment of the present invention sets forth a technique for transmitting data in a listen before talk (LBT) wireless transmission regime. A digital radio receiver is configured to simultaneously receive and decode digital data transmissions from multiple radio channels. A digital radio transmitter is configured to listen to the multiple radio channels prior to transmitting digital data on a selected one of the multiple channels, based on locally determined channel occupancy. Optimal LBT efficiency is achieved within the set of multiple channels, thereby improving overall transmission efficiency between the transmitter and the receiver.

    Abstract: An electronic electric meter for use in a networked automatic meter reading environment. The meter includes a meter microcontroller, a measurement microcontroller, a communication microcontroller and spread spectrum processor, and a plurality of other communication interface modules for communicating commodity utilization and power quality data to a utility. The meter measures electricity usage and monitors power quality parameters for transmission to the utility over a spread spectrum local area network (LAN) to a remotely located gateway node. The gateway node transmits this data to the utility over a commercially available fixed wide area network (WAN). The meter also provides direct communication to the utility over a commercially available network interface that plugs into the meter's backplane or bus system, bypassing the local area network communication link and gateway node.

    Abstract: Methods include those by which nodes in a Frequency Hopping Spread Spectrum (FHSS) wireless network may be flexibly configured for beacon transmission and reception. The method may allow for any node to synchronize to any other node's given frequency to receive one or more beacon (broadcast) packets from that node at the designated period. The method may include sending, by a first node, a message to one or more neighbor nodes and responding, by the one or more neighbor nodes, with a message to the first node, the response message including a beacon frequency, a beacon transmit time and information about the current hopping sequence. The first node periodically programs its receiver to the beacon frequency at the beacon transmit time and uses the hopping sequence to receive information including at least one of routing information and timing updates for hopping channel synchronization from the one or more neighbor nodes.

    Abstract: A node residing within a wireless mesh network is configured to transmit a state transition message to a downstream node also residing within the wireless mesh network. The state transition message indicates a new operating state for the downstream node. Upon receipt of the state transition message, the downstream node may transition to the new operating state and then transmit an acknowledgement message back to the node that sent the state transition message. Alternatively, the downstream node may transmit the acknowledgement message back to the node that sent the state transition message first, and then transition to the new operating state.

    Abstract: A system and method is presented for broadcasting from a utility node a request for network routing information, receiving at the utility node routing information from neighboring utility nodes in response to the broadcast request, and registering the utility node with an access point that provides ingress and egress to and from the network. A node is selected to function as a proxy gateway for one or more other nodes in the network. A new utility node becomes connected to one or more utility networks by registering with the proxy gateway. The proxy gateway transmits registration requests and registration information from each node to a back office server and/or a Domain Name Server via an access point for which the proxy gateway functions as its proxy.

    Abstract: The service phase of the electrical connection to a customer endpoint device located within a power distribution system is determined by various techniques. At the feeder level, the system may be programmed to induce disturbances, thereby causing missed zero crossings at the customer endpoint devices. The pattern of these disturbances is a controlled one, designed specifically to avoid causing noticeable disruption even to sensitive devices, but to be unusual enough that it is statistically unlikely to be naturally occurring. The monitoring of the zero crossing information is used to determine the phase of the service line to the customer endpoint devices.
