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.

Location information provided by multiple positioning systems is combined to provide an estimated user location. In performing the combination, location information provided by the positioning system that is currently deemed more reliable is provided greater weight than the location information provided from the other positioning system(s). Alternatively, one of multiple positioning systems is selected to calculate an estimated user location. The selected system is the one that is currently deemed more reliable based on some indicia of reliability. Using either approach, an accurate estimate of a user's location can be provided both in rural areas or other sparsely-populated areas as well as in urban areas or other areas prone to high multipath effects.

A Mixer/Ejector Wind Turbine (“MEWT”) system is disclosed which routinely exceeds the efficiencies of prior wind turbines. In the preferred embodiment, Applicants' MEWT incorporates advanced flow mixing technology, single and multi-stage ejector technology, aircraft and propulsion aerodynamics and noise abatement technologies in a unique manner to fluid-dynamically improve the operational effectiveness and efficiency of wind turbines, so that its operating efficiency routinely exceeds the Betz limit. Applicants' preferred MEWT embodiment comprises: an aerodynamically contoured turbine shroud with an inlet; a ring of stator vanes; a ring of rotating blades (i.e., an impeller) in line with the stator vanes; and a mixer/ejector pump to increase the flow volume through the turbine while rapidly mixing the low energy turbine exit flow with high energy bypass wind flow. The MEWT can produce three or more time the power of its un-shrouded counterparts for the same frontal area, and can increase the productivity of wind farms by a factor of two or more. The same MEWT is safer and quieter providing improved wind turbine options for populated areas.

A method and system for preventing the control of an aircraft from the cockpit. In an exemplary embodiment, the system could be triggered externally. For example, an air traffic control (ATC) station could determine that the aircraft has deviated from its planned flight path. If personnel at the ATC station decide that the deviation is not attributable to the actions of the authorized flight crew, the personnel can transmit a signal to the aircraft that disables all normal cockpit control of the aircraft. Once normal flight controls are disabled, the aircraft may execute a preprogrammed emergency flight plan via its autopilot system, with or without the use of a flight management system (FMS). The emergency flight plan could cause the aircraft to fly to a sparsely populated area and enter a holding pattern, or it could cause the aircraft to land in a sparsely populated area or at an airport using an autoland system.

The method includes using dynamic natural disaster modeling information to estimate a spatio-temporal distribution of a parameter of a potential natural disaster, wherein the modeling information is input to an instance of a weather forecast model which computes simulation results for natural disaster parameters for an area at a given time interval and the results produced on each time step within the time interval the estimate of the spatio-temporal distribution, and using static demographic data to estimate risk of impact of the parameter of the natural disaster on a populated area based on the estimated spatio-temporal distribution, wherein the demographic data is overlayed with the estimated spatio-temporal distribution via applying a weight to each populated area based on historical natural disaster incidents and related impact for each area.

Rotor blades for wind power installations are known in many different forms. In a wind power installation the rotors or the rotor blades thereof represent the main source of sound. For reasons relating to acceptance and noise prevention laws, the aim should/must be that of minimizing the levels of sound emission as wind power installations are often also set up in the proximity of residential accommodation. The levels of sound emission which hitherto occur with a wind power installation or a wind power converter also mean that wind power installations are faced with resistance from populated areas because of the sound they produce and for that reason such installations can be accepted sometimes with difficulty or not at all as authorities responsible for planning permission refuse permission for wind power installations because of the existing environmental requirements, noise also being an environmentally polluting factor. Therefore the object of the invention is further to improve the noise emission of wind power installations. Wind power installation rotor blade comprising means for reducing the sound produced by a rotor blade, wherein the means is formed by a fluid-repellent layer and/or surface which is provided at least on a surface portion of the rotor blade.

An improved plasma arc waste processing system has a crucible formed in a horizontally elongated shape with a low-ceiling-height plenum space above a melt pool and a waste input feed arranged sideways into the crucible. The plenum space conducts the off-gases through a channel into a horizontally adjacent, thermal resonant chamber. The combined volume of the plenum space and thermal resonant chamber provides a high ratio of plenum volume to surface area of melt pool for efficient pyrolization of waste at high throughput rates. The crucible and other system components can be arranged in standard sized cargo containers, to be modularly transported and assembled in populated areas or transported to and from remote areas, such as in medical crisis zones, military deployments, and war zones. As a further improvement, a water injector is used to inject water into the plasma field to remove excess carbon and form useful gas byrpoducts.

A wireless communication network can reliably deliver high priority broadcast information from base stations to mobile terminals located deep in building and those located in scarcely populated areas that are remote from the base stations. Each of the base stations of the wireless communication network comprises a broadcast information input unit for receiving high priority broadcast information and a transmission power changing unit for changing the transmission power of the downlink common channel when high priority broadcast information is input to it. As broadcast information is input, the transmission power changing unit changes the transmission power of the downlink common channel so as to boost the effective radiation power used by the downlink common channel of the base station at places in the coverage of the base station that are subjected to a propagation loss. The effective radiation power to the mobile terminals located at places in the coverage of the base station that are subjected to propagation loss is boosted to raise the reception level of the mobile terminals located at such places.
