    摘要: A method, computer program product, and client computer for allowing a user to modify one or more best-fit data points included within a first best-fit curve to define one or more modified best-fit data points. The first best-fit curve defines a volatility of an option, with respect to a strike price, for a first chronological period. A reference point along the first best-fit curve is determined. A Cartesian offset, with respect to the reference point, is determined for each of the modified best-fit data points.

    摘要: There is disclosed a system and method of formulating a batch comprising at least two ingredients. The ingredients are admitted to a container to partially fill it. The quantities of the ingredient in the container are determined, and a ratio of a target quantity to the determined current quantity for at least one ingredient is calculated. The next quantity of that ingredient to be admitted to the admixture is calculated by multiplying the target quantity by the calculated ratio to determine a corrected quantity. The corrected quantity of the ingredient is admitted to the admixture, and a quantity of another ingredient is admitted to the admixture to adjust the proportion of ingredients to the target formulation. These steps may be repeated until the batch is completed.

    摘要: This invention relates to an improved holder for a fishing rod. typical fishing rod holders are difficult to quickly and accurately adjust. Some even require the use of a tool to adjust. The claimed invention teaches a rod holder with a convenient adjustment mechanism that allows a user to adjust the angle of the rod holder in two planes without the use of a tool and with only one hand.

    摘要: A releasable locking assembly including a housing, a body defining a longitudinally extending flow bore having a first end and a second end disposed within the housing, a window defined through a radial wall of the body, a locking segment having an outer convex surface of a first radius defined by distance from a first axis, and an inner concave surface of a second radius defined by distance from a second axis different than the first axis, the locking segment disposed at least in part in the window, and a support member disposed within the body and moveable between a position where the support member drives the locking segment into engagement with the housing and a position where the support member unsupports the locking segment with regard to engagement with the housing.

    摘要: An open tip downhole expansion tool including a frustoconical member having a base at a diametrically smaller portion of the frustoconical member and a tip at a diametrically larger portion of the frustoconical member, the member having a radially outer zone and a radially inner zone and having an axial length extending from the base to the tip; an outer void in a material of the member along a length of the radially outer zone; and an inner void in a material of the member along a length of the radially inner zone, the outer and inner voids being located at different positions along the axial length of the frustoconical member, the outer and inner voids each causing the frustoconical member to present a first resistance to deformation when the voids are open and a higher resistance to deformation of the frustoconical member when the voids are collapsed.
