Abstract: An apparatus and method for mounting a wind turbine and blade assembly on the upper end of a wind turbine tower. In one aspect the apparatus generally includes a ginpole that is used to assemble the tower and a lifting frame or truss that is removably secured to a top bay assembly of the tower using the ginpole. The lifting frame or truss is operated using either cables or hydraulic rams and extends fore of the tower when the frame or truss is in a first position and generally above the tower when in a second position. When in the first position, a wind turbine or blade assembly can be hoisted to the top of the tower. The wind turbine or blade assembly is then moved into position for mounting to the tower as the frame or truss is pivoted to a second position. When the turbine and blade assembly are secured to the tower, the frame or truss is disconnected from the tower and lowered to the ground followed by the ginpole being lowered to the ground.

Abstract: The disclosed invention is utilized for mounting a wind turbine and blade assembly on the upper end of a wind turbine tower. The invention generally includes a frame or truss that is pivotally secured to the top bay assembly of the tower. A transverse beam is connected to the frame or truss and extends fore of the tower when the frame or truss is in a first position and generally above the tower when in a second position. When in the first position, a wind turbine or blade assembly can be hoisted to the top of the tower. The wind turbine or blade assembly is then moved into position for mounting to the tower as the frame or truss is pivoted to a second position. When the turbine and blade assembly are secured to the tower, the frame or truss is disconnected from the tower and lowered to the ground.

Abstract: A structural tower having a space frame construction for high elevation and heavy load applications is disclosed, with particular application directed to wind turbines. The structural tower includes damping or non-damping struts in the longitudinal, diagonal or horizontal members of the space frame. One or more damping struts in the structural tower damp resonant vibrations or vibrations generated by non-periodic wind gusts or sustained high wind speeds. The various longitudinal and diagonal members of the structural tower may be secured by pins, bolts, flanges or welds at corresponding longitudinal or diagonal joints of the space frame.

Abstract: The disclosed invention is utilized for mounting a wind turbine and blade upper end of a wind turbine tower. The invention generally includes a frame or tally secured to the top bay assembly of the tower. A transverse beam is e frame or truss and extends fore of the tower when the frame or truss is in a first erally above the tower when in a second position. When in the first position, a blade assembly can be hoisted to the top of the tower. The wind turbine or blade n moved into position for mounting to the tower as the frame or truss is pivoted to n. When the turbine and blade assembly are secured to the tower, the frame or ected from the tower and lowered to the ground.

Abstract: An isometric testing apparatus for performing isometric strength tests on individual muscles or joints of a patient includes a base, a seat coupled to the base, a vertical member coupled to the base, a horizontal arm coupled to the vertical member, and a force measuring device coupled to the horizontal arm. The base is configured for conserving space and allowing for placement proximal a corner. The chair is adjustably coupled to the base and may be adjusted to be located within the testing area, outside the testing area, and adjacent the testing area so that the chair may be used as needed or moved out of the way. The force measuring device is adjustably coupled to the base through the horizontal arm and vertical member and is horizontally and vertically adjustable for proper placement of the force measuring device. The force measuring device is pivotally mounted to the horizontal arm and pivots in a vertical plane to correct for any deflection of the vertical arm.

Abstract: First and second incline sensing devices measure the bending motion of the first body region and the second body region, respectively, in relation to gravity to provide range of motion determinations. With the incline sensing devices held against their respective body regions, a practitioner zeros a digital display provided on the device and the patient performs a range of motion exercise while the practitioner notes the angular value which is continuously updated on a display. The device is small, easily handled, and self contained. Numerous structures are provided to extend the useful life of an internal battery which provides power to all the components. The device utilizes programmed array logic components, which are reliable and consume very little power, to calculate the different between the orientation with respect to gravity of the two incline sensing devices. The difference is shown on a liquid crystal display.
