Abstract: A lighting device is provided with input terminals that receive corresponding terminals from any one of an analog or digital dimming device or a driver configuration device. Depending on the type of connected device, different circuits are enabled by a controller to receive dimming control signals from an analog or digital dimming device, or to receive device configuration data from a multiple driver configuration device. A wireless interface circuit receives and stores configuration data via an antenna. The controller automatically detects whether one of the analog or digital dimming device or the driver configuration device is coupled to the input terminals, enables a corresponding one of the analog and digital interface circuit or the driver configuration interface circuit, and generates output current reference signals for regulating the output current from the driving circuit, said reference signals corresponding to the received dimming control signals via the analog and digital interface circuit.

Abstract: A lighting system includes various ballasts or LED drivers having respective dimming interface circuits coupled in parallel to an external dimming device. Each device includes a controller regulating output to a lighting load based on desired dimming output. Dimming interface circuits coupled are between the controller and the external dimming device, each configured to dynamically adapt a level of constant current sourced from the dimming interface circuit to the external dimming device via first and second interface terminals, based on a determined analog mode or digital mode associated with the external device. The dimming interface circuit generates dimming control signals to the controller based on dimming input signals received via the first and second interface terminals, and in a digital mode, the interface circuit generates digital pulse signals to the external dimming device via the interface terminals for bidirectional communications therewith.

Abstract: A wind turbine blade having two shell portions bonded together to form a wind turbine blade having an interior space having an axial length. A web disposed between the shell portions in the interior space and extending substantially the axial length thereof. Lightning receptors are disposed on the shell portions and a conductor is disposed in the interior space. The conductor is configured to contact the lightning receptors. One shell portion of the two shell portions has a removable section, e.g. a plug, receptor or panel, to provide access to the opposite conductor. A cable mounted on the web is configured to extend substantially the axial length of the wind turbine blade and is in electrical contact with the conductor.

Abstract: A blade for the use in the generation of power has a leading edge and a trailing edge. A first shell portion of the blade extends from the leading edge to the trailing edge. A second shell portion of the blade also extends from the leading edge to the trailing edge. A root portion of the blade is positioned proximate the wind turbine and a tip portion which extends from the root portion away from the wind turbine. A trailing edge insert is positioned between the first shell portion and the second shell portion proximate the root portion. The trailing edge insert has a surface which extends between and separates the first shell portion from the second shell portion at the trailing edge, such that the insert provides a high lift profile for increased blade efficiency.
