Abstract: An improved golf putter is provided. In one aspect, the putter has an isolated face. The face is connected to a semicircular support member forming a semicircular aperture between the face and the support member. A pair of ribs is connected to the semicircular support member and forms a first aperture therebetween. A first wall is connected to the pair of radial ribs and to a second wall. The first wall and the second wall are separated by a connecting wall, and form at least two apertures therebetween. A plurality of gaps is formed between the first wall and the face. The plurality of gaps structurally isolates the face from the structure thereby forming an improved golf putter.

Abstract: An expandable tubular includes a plurality of leaves formed from sheet material that have curved surfaces. The leaves extend around a portion or fully around the diameter of the tubular structure. Some of the adjacent leaves of the tubular are coupled together. The tubular is compressed to a smaller diameter so that it can be inserted through previously deployed tubular assemblies. Once the tubular is properly positioned, it is deployed and coupled or not coupled to a previously deployed tubular assembly. The tubular is useful for all types of wells and boreholes.

Abstract: A method is disclosed of providing an optimal minimum mass topology for a structure based on a set of design criteria including at least one support point and at least one force to be applied to the structure. The method includes the steps of: identifying a plurality of nodes within a structure design domain, and assigning an initial density value to said plurality of nodes; conducting a finite element analysis on the nodes; determining one of a stress intensity or strain energy values for each node; ranking the nodes by relative stress intensity or strain energy values; adjusting the density value for each node; and repeating the steps of conducting a finite element analysis on said nodes, wherein the step of adjusting each density value for each node is performed according to a family of statistical distribution functions that gradually transition to a bimodal distribution wherein nodes are either fully dense or effectively void thereby providing an optimal topology.

Abstract: A golf club head designed to act under impact load as a bridge comprising a face; an inertial support system; a rear structure; and a force transfer system, under impact load the force transfer system, in cooperation with the inertial support system, elongating the rear structure and controlling the bending of the face, the pattern of bending of the face being a substantially bridge-like pattern of bending or a substantially modified bridge-like pattern of bending.

The method also includes the step of repeating the steps of conducting a finite element analysis on the nodes, determining the stress intensity value for each node, ranking the nodes by relative stress intensity values, and adjusting the density value for each node until a termination criteria is realized, thereby providing an optimal topology.
