Abstract: In one aspect, a method for assembling a tower section of a lattice tower structure for a wind turbine on a tower assembly fixture may generally include installing a first trolley onto a first fixture arm of the fixture and installing a second trolley onto a second fixture arm of the fixture. In addition, the method may include securing a first support leg of the tower section to the first trolley, securing a second support leg of the tower section to the second trolley and coupling at least one secondary support member between the first and seconds support legs.

Abstract: A system for assembling a tower section of a lattice tower structure for a wind turbine may generally include a tower assembly fixture having a plurality of radially extending fixture arms, wherein each fixture arm extends between a first end and a second end. In addition, the system may include a plurality of trolleys. Each trolley may include a base frame configured to be coupled to one of the fixture arms between its first and second ends and a leg mount pivotally coupled to the base frame. The leg mount may be configured to be coupled to a bottom end of a support leg of the tower section such that, when each of the support legs is coupled to its respective leg mount, the support legs are supported above the tower assembly fixture at a substantially vertical orientation.

Abstract: One of the major structural components in a space frame tower is the tower leg. A novel and nonobvious tower leg structure is provided which provides significant advantages and benefits over previously available structures.

Abstract: A bolt connection assembly is provided that is particularly well-suited for connecting structural members of a lattice tower structure for a wind turbine. The bolt connection assembly includes a bolt component having a head and a shaft and a structural bore component having a bore defined therethrough for receipt of the bolt component. The shaft includes a knurled surface such that the knurled surface defines an outermost shaft diameter. Moreover, the knurled surface includes a plurality of knurls, each defining a non-arcuate edge. The bore defines a bore diameter, wherein the outermost shaft diameter is greater than the bore diameter. In an assembled state of the bolt component and the structural bore component, the bolt component may be inserted within the bore such that the knurled surface may be deformed to friction fit within the bore diameter.

Abstract: A removable modular connector housing is disclosed and claimed for use in an electronic device and two devices that are insertable in the modular removable connect or integral thereto. The removable connector is particularly suited for insertion within a thin-architecture communications card such as a PCMCIA card. A standard interface scheme between the removable modular connector includes a multiple-pin socket and/or a multiple-runner array that is external to the housing of the removable modular connector. The removable modular connector is suited for various types of devices including land line jacks, video interfaces, cable connects, and other electronic devices that are connectable to larger systems such as computers, cameras, and hand-held digital assistants.

Abstract: The present invention relates to a system for interconnect modularity of an electronic communication card such as a PCMCIA card where a printed circuit board has a peninsular electrical lead configuration upon a finger section thereof and an electronic device that is slidably disposed upon the peninsular lead configuration. The electronic device preferably has a standardized footprint and the device may be an electrical interconnect such as a cable, a jack such as an RJ-11 jack, an IRDA transceiver, a combination cable and 4-pin connector, and an electronic video interface. The system provides a solution to insufficient spacing between tip and ring leads and remaining leads on a 15-pin connector required by various international safety standards. The system may also include a translucent portion of the electronic device and a light source that, in combination provide a visual diagnostic output for the user.
