    Abstract: A method and apparatus for transferring tubular stands between a substantially horizontal position on the catwalk and a substantially vertical position at the rig floor entry. In one embodiment of the invention, this is accomplished by moving bundles of individual tubulars to the process area, where a stand make-up/break-out machine, also called a bucking machine, makes up the tubular stands. The bucking machine aligns and stabs the connections and makes up the connection to the correct torque. The tubular stand is then transferred from the bucking machine to a stand storage area or to a trolley pick-up area. When additional stands are needed by the drilling operation, a trolley is moved into position over the trolley pick-up area to retrieve the stands previously placed in the trolley pick-up area. The stands are clamped to the trolley and the trolley is moved from a substantially horizontal position to a substantially vertical position at the rig floor entry. A vertical pipe-racking machine transfers the stands to the traveling equipment. The traveling equipment makes up the stand connection and the stand is run into the hole. The operation can also be reversed to remove stands from the rig floor entry and break out the stands in a horizontal position.

    Abstract: The present invention provides an intraocular lens (IOL) having an optic with a posterior and an anterior refractive surfaces, at least one of which has an aspherical profile, typically characterized by a non-zero conic constant, for controlling the aberrations of a patient's eye in which the IOL is implanted. Preferably, the IOL's asphericity, together with the aberrations of the patient's eye, cooperate to provide an image contrast characterized by a calculated modulation transfer function (MTF) of at least about 0.25 and a depth of field of at least about 0.75 Diopters.

    Abstract: In one aspect, the present invention provides a method of designing a diffractive ophthalmic lens (e.g., an intraocular lens (IOL)) that includes providing an optic having an anterior refractive surface and a posterior refractive surface, wherein the optic provides a far-focus power (e.g., in a range of about 18 to about 26 Diopters (D)). A truncated diffractive structure can be disposed on at least one of the surfaces for generating a near-focus add power (e.g., in a range of about 3 D to about 4 D). And the diffractive structure can be adjusted so as to obtain a desired distribution of optical energy between the near and far foci for a range of pupil sizes.
