Abstract: Certain iridium compounds which may comprise an iridium(III)-ligand complex having the general formula: (C?N)2—Ir—(N?N). (C?N) and (N?N) may each represent a ligand coordinated to an iridium atom. The iridium compounds may have a primary phosphorescent photoluminescence peak wavelength in the near-infrared (IR) range. Also, organic devices that use certain iridium compounds. The organic device may comprise an organic layer and the organic layer may comprise any of the iridium compounds disclosed herein. Also, organic devices that use certain metalloporphyrin compounds. The metalloporphyrin compounds may comprise a core porphyrin structure with four pyrrole rings. The metalloporphyrin compounds may have a primary phosphorescent photoluminescence peak wavelength in the near-IR range.

Abstract: A winch for use in a heave compensation system has a winch drum (42) driven by an AC asynchronous motor (50) via a gearbox (52). The motor (50) is controlled by a variable speed control (58) as a function of heave speed. The motor (50) and its drive train, and the winch (42), are chosen to have low inertia. The winch pays out and reels in to compensate for heave substantially instantaneously, without the need for prediction of wave patterns.

Abstract: In order to carry out a three-dimensional reconstruction of an object acquired by a series of conical projections on a two-dimensional multidetector, the object is estimated by a sampled function. The sampled function is projected and the projections of the sampled function are compared with the measurements resulting from acquisition on the 2D multidetector. A new estimation of the object is deduced therefrom and these operations are repeated until the comparison is satisfactory. In order to project, the sampled three-dimensional object is decomposed on a space of Gaussian basis functions. The contribution of the basis functions is computed for each image of the projection images, these contributions being equal to the integral of the product of the basis functions and of a support for illumination of the image element.
