A system, method and computer program product provides for power line communications (PLC) over electric power lines includes a device mountable near an electrical distribution transformer (DT) to provide a high speed interface and communicates with one or multiple access devices, which provide low speed interfaces for analog signals or digital signals over RS 232, RS 485, optical, wireless and Ethernet. The device transmits data to/from these access devices over the electric lines to other repeaters over one or more wires of an electrical line or over multiple lines, and serves to strengthen and improve signal quality. Upon detecting a wire or line is having problems carrying data, the data is sent over other wires, and upon power line failures, wireless backup to mobile/GSM and WiMax networks is utilized. The device permits utilities and others to read electric meters, monitor the power quality of the distribution grid and detect power losses/failures/outages, and permits telecom service providers and others to provide a communications link to cell phone towers, WiFi Access Points and enable broadband Internet and telephony in rural, remote or sparely populated areas.

Systems, methods, and apparatus embodiments for electric power grid and network registration and management of active grid elements. Grid elements are transformed into active grid elements following initial registration of each grid element with the system, preferably through network-based communication between the grid elements and a coordinator, either in coordination with or outside of an IP-based communications network router. A multiplicity of active grid elements function in the grid for supply capacity, supply and/or load curtailment as supply or capacity. Also preferably, messaging is managed through a network by a Coordinator using IP messaging for communication with the grid elements, with the energy management system (EMS), and with the utilities, market participants, and/or grid operators.

The communication system of one embodiment is for communicating data through a power distribution system having a medium voltage power line and low voltage power line and comprises a first device comprising a first wireless transceiver, a first modem in communication with the first wireless transceiver and the medium voltage power line. The system may also comprise a second device comprising a second wireless transceiver in wireless communication with the first wireless transceiver; and a second modem in communication with the second wireless transceiver and the low voltage power line.

A process control management method in a computer system for configuring and supervising a process plant includes providing an interactive user interface to manage a plurality of objects in the process plant, where each of the plurality of objects corresponds to a physical or logical entity in the process plant, including generating a navigation pane to display a set of selectable items, each in the set of selectable items corresponding to a respective one of the plurality of objects, and generating a command pane to display a set of selectable controls, each in the set of selectable controls corresponding to a task to be performed on at least one of the plurality of objects in the process plant; receiving a selection of one of an item in the set of selectable items via the navigation panel and a control in the set of selectable controls via the command panel; determining an operational context based on the received selection, wherein the operational context corresponds to one of a range of actions applicable to the selection if the selection is an item selection, or a range of items to which the selection is applicable if the selection is a control selection; and adjusting one of the navigation pane or the command pane according to the operational context, including displaying a subset of selectable items in the navigational pane, wherein each in the subset of selectable items is within the range applicable to the selection, if the selection is a control selection, and displaying a subset of selectable controls in the command pane, wherein each in the subset of selectable controls is within the range applicable to the selection, if the selection is an item selection.

PCT No. PCT/RU95/00241 Sec. 371 Date Jan. 27, 1998 Sec. 102(e) Date Jan. 27, 1998 PCT Filed Nov. 10, 1995 PCT Pub. No. WO97/05557 PCT Pub. Date Feb. 13, 1997An electronic gaming system is disclosed that includes a central computer station, a plurality of peripheral computer stations, and a data exchange network for coupling the peripheral computer stations to the central computer station. The central computer station includes an administrative subsystem, a player's registration subsystem, a game accounts managing subsystem, an information tabulating, storing and searching subsystem, a game recording subsystem, a scoring subsystem, a wagering and betting subsystem, an executive gaming subsystem, an electronic payment subsystem, an information protection subsystem, a secure communications subsystem, and a game selection subsystem. Each of the peripheral computer stations include a subsystem for admitting and registering players with the central computer station and a gaming interface subsystem. To ensure security of the electronic gaming system, a player seeking to enter the system transmits an encoded message from their peripheral computer station to the central computer station that includes a set of key attributes associated with the player. The central computer station decodes and compares the transmitted set of key attributes with individual information previously stored in the information protection subsystem in order to identify each player during registration based upon the set of key attributes transmitted by each player. The system may automatically control money transactions with each player's bank accounts based upon the player's scoring and wagers in each selected game.
