Aspects of the present disclosure correspond to managing premises by processing input data, such as the appliance's operational and usage profiles and/or individual's health and behavior profile. One aspect of the present disclosure related monitoring aspect based on processing the appliance's operational and usage profiles. For example, the appliance's operational parameters together with sensor data associated with the appliances can be utilized to monitor the premises. Another aspect of the present disclosure related to generating command instructions for the individual (e.g., premise user) based on the individual's health and behavior profile. For example, the usage of the appliances can provide to the individual one or more commanding instructions based on the individual's health and behavior profile.

Managing local sensor data based on profile information

A wind turbine with improved response to wind conditions is provided. Blade flap angle motion is accompanied by a change in pitch angle by an amount defining a pitch/flap coupling ratio. The coupling ratio is non-constant as a function of a flap angle and is preferably a substantially continuous, non-linear function of flap angle. The non-constant coupling ratio can be provided by mechanical systems such as a series of linkages or by configuring electronic or other control systems and/or angle sensors. A link with a movable proximal end advantageously is part of the mechanical system. The system can provide relatively large coupling ratios and relatively large rates of coupling ratio changes especially for near-feather pitches and low flap angles.

Method and apparatus for controlling pitch and flap angles of a wind turbine

A wind turbine is configurable with at least one blade is pitched to provide relatively high sensitivity to wind direction or sheer so as to perform a rudder function which moves the blades such that the vertical plane defined by the blade ends is substantially parallel to the wind direction. In one aspect, the wind turbine has at least two different blades having two different blade pitches. In one embodiment, the rudder action configures a two bladed wind turbine such that a non-rudder blade, having a pitch different from the rudder blade, has its free end pointing substantially directly into the wind, providing relatively low cross-sectional resistance to the wind and accordingly relatively low load.

Rotor pitch control method and apparatus for parking wind turbine

A structure and method for transferring load, particularly bending load, from a blade to a blade hub, such as for use in a wind turbine device, is provided. In one embodiment, the structure includes two or more spaced-apart annular rings, respectively contacting the inner surface of a blade root end, and the outer surface of a hub spindle, with a web extending therebetween.

Wind turbine rotor blade root end

A wine turbine with blades having a high lift-to-drag ratio is provided. A hydraulic or other control system is used to control cone angle, such as in response to flap moment. Pitch of blades is controlled, such as in relation to the blade flap angle. Teeter motion is controlled preferably as a function of teeter angular velocity.

Rotor device and control for wind turbine

The presser wheel support comprises a depending support arm pivotally connected to the end of a cantilevered arm projecting at a downward slope in the tailing direction from a net hauler sheave frame member preferably in the form of a transverse suspension plate overlying the net hauler sheave. A fluid operated jack interacting between the hauler sheave frame and the support arm generally in the common plane of the hauler sheave and presser wheel urges the wheel yieldably against netting descending in the main hauler sheave groove so as to increase the hauling traction and hauling force exerted on the netting to avoid slippage and damage of netting.
