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.

An intelligent audio speaker that uses a power line communication element to provide audio distribution within homes, businesses, apartment complexes, and other buildings. Multiple intelligent audio speakers may be networked together, with common control. The intelligent audio speaker may, in some embodiments of the present invention, contain enhanced ambient backlight effects to further enhance the listener's experience. In some embodiments of the present invention, an existing audio speaker is retrofitted to an intelligent audio speaker using a retrofit kit.

An integrated network adapter is operable to establish a network interface with a plurality of media types, including at least a power line network and a telephone line network, based on pre-configuration, upon initialization and dynamically during operation. The adapter further is operable to establish network interfaces simultaneously or separately with a plurality of media types and provide that a communications event can occur simultaneously or separately over a plurality of media types.

Integrated universal network adapter

A power outlet adaptor device having a housing, at least one multimedia, networking and/or communications component, and an electrical socket box including at least one electrical socket is provided. The multimedia, networking, and/or communications component is secured within the housing and provides multimedia, networking and/or communications capabilities. The electrical socket accommodates an electrical device plug. The housing fits around the electrical socket box. The electrical socket box electrically couples to the multimedia, networking, and/or communications component.

Networking and multimedia adapter for power outlets

A system and method of delivering synchronized audio and audio/video signals in the form of analog signals and streamed data over networks such a hybrid power line communications network is described. Signal magnitude matching by monitoring directly feed audio outputs is also provided.

Delay management of presentation output system and method

Powerline networks are inherently noisy and subject to power surges, spikes, and other events. Devices exist to combat these issues and protect electrical appliances that are connected downstream from the power sources for theses devices, but these devices usually also severely limit data communication that may also be desired on this network. This invention provides an intelligent, self-aware powerline conditioning and communication node that allows for, or even improves, data communication on the network, and still provides for noise reduction, line filtering, and surge protection for downstream electrical appliances.

Intelligent, self-aware powerline conditioning and communication node

When an audio distribution system is installed, it is normally required to install wiring between the audio source or sources, and all of the speakers that are installed throughout a building or structure. The installation of this wiring is normally time consuming and difficult, and can be a large cost component of the system installation. Therefore, there is a need for an audio distribution system that makes use of, and takes a benefit from, already installed electrical power wiring, or allows a lesser number of wires to be run where new installations are necessary, through the means of upgrading the system to provide uninterrupted power to the powered speakers while maintaining the ability to control lighting fixtures powered through the same wiring infrastructure.

Method and system for audio distribution in installations where the use of existing wiring is preferred

Data throughput rate in a power line communications ('PLC') system is controlled by generating PLC carrier signals in accordance with a PLC signal frame structure containing payload symbols where the payload symbol length is selected based on at least one of a PLC system channel quality and node configuration data. The selected payload symbol length determines the processing operations that a source PLC transceiver performs for generating PLC signals or that a destination PLC transceiver performs for extracting information content from received PLC signals. The payload symbol lengths can be selected to maximize the data throughput rate while maintaining compatibility with prior art PLC system protocols and standards that require a PLC signal frame structure and its payload portion to have fixed, predetermined lengths.

Method and system for maximizing data throughput rate in a power line communications system by modifying payload symbol length

Data throughput rate in a power line communications ('PLC') system is controlled by generating PLC carrier signals in accordance with a PLC signal frame structure containing payload symbols where orders of modulation are selected for the individual PLC carriers based on evaluation of at least one of a PLC system channel quality and node configuration data. The selected orders of modulation determine the processing operations that a source PLC transceiver performs for generating PLC signals or that a destination PLC transceiver performs for extracting information content from received PLC signals. The orders of modulation can be selected to maximize the data throughput rate while maintaining compatibility with prior art PLC system protocols and standards that require a PLC signal frame structure and its payload portion to have fixed, predetermined lengths.
