Abstract: A method for replacing an existing generator frame that supports a generator of a wind turbine includes removing the generator from atop the existing generator frame. The method also includes dismounting a control cabinet of the wind turbine from the existing generator frame. More specifically, the control cabinet is electrically connected to one or more wind turbine components via a plurality of cables. The method further includes relocating and securing the control cabinet to an uptower location within a nacelle of the wind turbine with the plurality of cables remaining electrically connected. As such, the method includes removing the existing generator frame from within the nacelle. Moreover, the method includes installing a new generator frame in place of the removed existing generator frame. Thus, the method also includes remounting the control cabinet to the new generator frame.

Abstract: In a multiple-input, multiple-output (MIMO) enabled mesh network, streams for transmitting data from a node to a destination node are controlled based on next hop latency and available stream capacity at neighboring, next hop nodes. Routing information maintained and dynamically updated at each node includes latency information associated with each next hop for transmission from the node to a given destination node and current available stream capacity for such next hop nodes. A controller at the node utilizes that information to select one or more next hop nodes to which the data is forwarded as well as to determine a number of streams that may be initiated with each selected next hop node.

Abstract: A sensor profile based data aggregation method for aggregating data in a sensor network, which includes a plurality of sensor nodes, is provided. This method includes steps of determining types of sensors included in the sensor nodes, and generating a sensor profile that includes information on each type of the sensors. The information includes a filtering criterion and aggregation operators defined for the each type of the sensors. Once the sensor profile is created, the profile is parsed into a header file, and the header file is compiled with other sub-modules to generate a sensor profile based aggregation module. The sensor profile based aggregation module is installed in each of the sensor nodes. Whenever, sensor data is received in the sensor node, the data is filtered according to the filtering criterion defined in the sensor profile, and data aggregation is simultaneously with given operators.

Abstract: A small office/home office base transceiver station (SOHO BTS) server capable of managing interference by correlating pilot strength measurements sent by mobile devices and directing the attenuation settings for each transmit path. An array of antennas coupled to an array of transmit paths are selectively activated one at a time. When a transmit path is activated, the SOHO BTS server sets the associated variable attenuator to its maximum level. The SOHO BTS server detects whether a radio environment report or and a pilot strength measurement message (PSMM) containing information about a mobile station's pilot strength is present. When the pilot strength is greater than a predetermined value, the SOHO BTS server increases the setting on the attenuator. Otherwise, the SOHO BTS server decreases the attenuator setting until such pilot strength information is available or if the lowest attenuator setting has been set. The other transmit paths are also tested accordingly.

Abstract: A method, apparatus, and article of manufacture provide the ability to render an edge effect for an object. An object is obtained in a computer-generated rendering having vector geometry. An interior geometry is created for a fill of the object. Contour geometry is created for an outline stroke that covers an edge of the object. A proximity to the edge of the object is calculated for each pixel of the object and each pixel of the contour geometry. An effect is then rendered based on the proximities.

Abstract: A small office/home office base transceiver station includes an acoustic sensor array. Directions from which acoustic signals are detected are presumed to correspond to the interior of the building within which the base transceiver station is located, and with human activity within that interior, while directions from which few or no acoustic signals are detected are presumed to correspond to proximate outside walls. Transmit power gain for directional antenna array elements used for communications are then set to reduce transmission of power in directions that might result in interference with adjacent base transceiver stations.

Abstract: An apparatus and method is disclosed for selecting a handoff target base station in a wireless network. The apparatus comprises a handoff controller within a wireless mobile station that selects an optimal target base station for handoff based on pilot signal strength measurements of at least two candidate base stations and one of: a location of the wireless mobile station, a velocity of the wireless mobile station, and a direction of motion of the wireless mobile station. The present invention uses more than just pilot strength measurements to select an optimal target base station for handoff. Incorporating position location information in the handoff decision causes the handoff decision to be more reliable. This reduces the number of unnecessary handoffs and results in better system performance.

Abstract: Beamforming techniques to limit radiated power where there is the potential for interference with macro-cellular coverage or with adjacent mobile stations. Smart antenna beamforming techniques (including the use of angle of arrival information) are combined with access probe information to determine the direction for radiated power and the level of the needed transmitted power as well for the small office or home (SOHO) environment. The placement of RF power in the SOHO specific to where it is needed, minimizes radiating power in directions where it will cause interference with macrocell coverage. In addition, the beamforming techniques provide a base transceiver station with an economical method to quickly solve coverage issues internal to a SOHO, without introducing interference external to this coverage environment. In addition, there specific placement of the RF power where it is needed provides an increase in spectral efficiency of a deployed network.

A sensing component is disposed along a surface of the mobile communications device, proximal to the array of antenna elements. A processor component is communicatively coupled to the sensing component. An implementation element is communicatively coupled to the processor component, and to the array of antenna elements. The sensor component generates data characterizing the proximity of a foreign object to the array of antenna elements; which the processing component uses to determine a configuration for the array of antenna elements. The implementation element modifies the array of antenna elements, responsive to the configuration determined by the processor component.
