In one embodiment of this invention, identical communicating node elements are constructed and placed throughout a power delivery network. Each of these node elements supplies features and options that facilitate peer-to-peer communications, data and service aggregation, propagated interfaces and distributed computational power. The network of interacting node elements, built with a common architecture, gives the power delivery network advanced capabilities for utilities and customers. These advanced capabilities include self-healing, highly secure communications, real-time interactions between any devices, and so on.

Atomic self-healing architecture in an electric power network

The invention presents a novel method to channel estimation in OFDM systems. The embodiment of this invention is a block of new logic and modifications performed to other components of the system, added to any existing OFDM receiver, which utilizes information available from other blocks as found in the receiver. This logic would improve the units' error rate because of the improved channel quality estimations it makes available. This improvement is made possible because both channel noise data and channel signal data are used in the estimation process. This data goes through a learning process over time and multiple data blocks for further improvements in the quality of the estimate. This improvement is possible without any direct communications with other remote units, but it could be used in a multi-node environment to improve the performance of the system as the whole.

Method and system of channel analysis and carrier selection in OFDM and multi-carrier systems

Power line communication ('PLC') signals are transmitted between a head-end PLC transceiver coupled to multiple remote PLC transceivers over a electric power and communications distribution network in accordance with a timing controlled PLC data frame which determines how much bandwidth is allocated to downstream transmission from the head-end to the remotes and to upstream transmissions from one or more of the remotes to the head-end. The configuration of the timing controlled data frame can be dynamically modified to achieve higher bandwidth for the downstream traffic and to satisfy changing bandwidth needs of each remote.

Method and system for timing controlled signal transmission in a point to multipoint power line communications system

Fault detection and power network quality monitoring are performed for a power line network using power line communications ('PLC') signal transceiving and data processing capabilities. Power line signals are continuously received and processed to obtain signal data representative of power line network operating conditions that are expressed in the received power line signals. The harmonic content and noise signature of the signal data are evaluated with reference to known fault signature data and power line network topology properties for detecting and identifying the location of an existing or anticipated fault in the power line network and assessing power transmission quality of the network.

Method and system for power line network fault detection and quality monitoring

System, apparatus and method for connecting a passive optical network ('PON') to a power line communications ('PLC') network using a PLC HeadEnd installed at the PON to provide for distribution of high speed, broadband data communications services available on the PON to the PLC network using high speed, broadband PLC data signals. Where the PLC HeadEnd is installed on a medium voltage power distribution network, a PLC bypass unit is installed at a medium voltage/low voltage power transformer in the PLC network to provide PLC signal connectivity between the MV and LV networks. A PLC residential gateway is installed at each end user facility, such as a home or business, desiring broadband service available on the PON.
