Abstract: A transmitting element for generating a magnetic field for tracking of an object includes a first spiral trace that extends from a first outer origin inward to a central origin in a first direction. A second spiral trace can extend from the central origin outward to a second outer origin in the first direction. The second spiral trace can extend from the central origin to the second outer origin in the first direction. The first spiral trace and the second spiral trace can be physically connected at the central origin to form the fluorolucent magnetic transmitting element and at least a portion of the first spiral trace overlaps at least a portion of the second spiral trace.

Abstract: A tool for reducing vibrations in wind turbine blades at standstill includes an elongate sleeve formed of a net-like material for fitting over the blades, wherein the sleeve is formed with at least one protruding structure extending along at least a part of the length of the sleeve having an undulating form, and which is arranged so that when the sleeve is fitted on a blade the protruding structure or structures lie at the leading and/or trailing edge of the blade. A method for securing wind turbine blades against oscillations is also disclosed.

Abstract: A wind turbine blade for a wind turbine includes an elongate body having a root end, a tip end, a leading edge, a trailing edge, a pressure side and a suction side, wherein the elongate body defines a longitudinal axis extending along a length of the elongate body from the root end to the tip end. The elongate body includes a pre-bend configured such that when the wind turbine blade is mounted on the wind turbine and orientated in an operative position, the blade generally curves in an upwind direction such that the tip end of the blade is positioned more upwind than the root end of the blade. The curve that defines the longitudinal axis of the elongate body has an inflection point between the root end and the tip end of the blade. A method of making such a wind turbine blade is also disclosed.

Abstract: The present invention provides systems and methods for production of activatable diazo-derivatives for use in labeling nucleotides. Labeling nucleotides is accomplished by contacting a stable hydrazide derivative of a detectable moiety with an activating polymer reagent which is used to directly label the nucleotide sample. Labeling occurs on the phosphate backbone of the nucleotide which does not perturb hybridization of the labeled nucleotide with its anti-sense strand. Since the method involves direct labeling, all types of nucleotides can be labeled without prior amplification or alteration.

Abstract: A blade (20) for a wind turbine (10) generally includes a shell body (26) extending between a leading edge (30) and a trailing edge (32), an inner spar (36) supporting at least a portion of the shell body (26), and a damping element (42) coupled to the inner spar (36). The damping element (42) is configured to adjust the structural pitch of the blade (20) to dissipate edgewise vibrations of the blade (20). The damping element (42) may be incorporated into the spar (36) upon manufacture of the blade (20) or installed as a retro-fit modification to existing blades (20).
