Abstract: Electronic systems for controlling submersible pumps are provided herein. In certain configurations, a pump system includes three or more submersible pumps used for pumping fluid from a reservoir, sensors used for generating sense signals indicating a fluid level of the reservoir, and a control circuit for selectively activating the pumps based on the sense signals so as to control pumping of fluids from the reservoir. In certain implementations, the control circuit is operable in a plurality of user-selectable operating modes associated with different pump activation sequences in response to the fluid level of the reservoir rising.

Abstract: A method and associated system are provided for removing a drive train component, such as a gearbox, from a rotor shaft uptower in a wind turbine, wherein the component is supported by transversely extending mounting arms at mount locations on the wind turbine frame. The drive train component is supported from above or below and the mount locations. At each mount location, a removal fixture is installed that includes an actuator that moves linearly essentially parallel to the rotor shaft. The mounting arms are simultaneously engaged with the respective actuators, which are controlled to linearly push the mounting arms until the drive train component disengages from the rotor shaft.

Abstract: Systems and methods that mitigate inventory overstock of a retail product are provided. The systems and methods receive inventory information for the retail product and determine, according to the inventory information for the retail product, whether a number of stock cover days is greater than a stock cover days threshold. It is also determined, according to the inventory information for the retail product, whether a projected inventory is greater than an overstock units threshold. When the number of stock cover days is greater than the stock cover days threshold, and when the projected inventory is greater than the overstock units threshold, it is determined whether another store location is ordering the retail product, and when another store location is ordering, an overstock rebalancing alert is provided to a user.

Abstract: The present disclosure is directed to systems and methods for removing or installing a pitch bearing of a wind turbine. The method includes installing a first pulley block at an up-tower location of the wind turbine and configuring a second pulley block with the pitch bearing. A pulley cable is routed from a ground location over the first pulley block to the second pulley block such that the second pulley block is configured to slide along the pulley cable. The method also includes rotating the pitch bearing to a tilted position. Thus, the method further includes lowering or lifting the pitch bearing in the tilted position so as to prevent the pitch bearing from colliding with the tower.

Abstract: A network authentication system and method is described for authenticating multiple profile accesses from a single remote device. A device remote from a web server, yet connected to the web server via, for example, the Internet, can allow multiple users to register their profiles within the device. The profiles are registered using a pre-existing user ID and password corresponding to, for example, the user's financial accounts. Multiple profiles and, specifically, the indicia of those profiles, can appear on the display of the remote device allowing each user the ability to select their own registered profile. Access to a profile is granted when the user enters their private PIN. Once the PIN is entered, the private information such as financial account information will be securely forwarded from the web server to the remote device.

Abstract: A method for removing a rotor blade from a wind turbine may generally include installing a blade sock around an outer perimeter of the rotor blade, coupling a support cable to the blade root, lowering the rotor blade relative to the hub using the support cable, coupling at least one pulley cable between the rotor blade and a winch using at least one pulley, moving the pulley cable relative to the pulley to lower the rotor blade relative to the hub, applying a force through the blade sock as the pulley cable is moved relative to the pulley in order to control an orientation of the rotor blade and further lowering the rotor blade to a location on or adjacent to the support surface.

Abstract: The present disclosure is directed to a system and method for lifting and/or removing a rotor blade to and from a wind turbine. In one embodiment, the system includes an up-tower pulley mounted on an up-tower location of the wind turbine, first and second ground winches, a pulley cable from the first ground winch over the up-tower pulley and attached to the rotor blade, a guide line attached between an up-tower location of the wind turbine and the second ground winch, a guide pulley mounted on the guide line, and a guide cable from the guide line over the guide pulley to the rotor blade. Thus, the guide pulley is configured to move along the guide line during lifting and removing of the rotor blade so that the guide cable can control an orientation of the rotor blade relative to the tower during lifting and removing of the rotor blade.
