Publication number: 20030144069Abstract: A method (100) and system (20) for predicting a coefficient of restitution (COR) of a golf club (30) or golf club head (36) is disclosed herein. The system (20) and method (100) are able to predict the COR in a non-destructive manner for a particular golf ball and impact speed. The system (20) and method (100) utilize a vibration sensor (24) attached to the face (34) of a golf club (30). The vibration sensor (24) is excited with an excitation device (26), and data is transmitted to an analyzer (22). A mathematical model of the golf club (30) is created allowing for the coefficient of restitution to be predicted without destroying the golf club (30).Type: ApplicationFiled: March 21, 2003Publication date: July 31, 2003Applicant: Callaway Golf CompanyInventors: Matthew J.

Patent number: 6478692Abstract: A compliant golf club head permits a more efficient impact between a golf ball and the golf club head. Material and geometry constraints of a striking plate of the golf club head can reduce energy losses caused by large strain and strain rate values of the golf ball, these constraints on the striking plate yield a measure of the impact efficiency of the golf club head. Designating a required natural frequency range of the striking plate provides improved impact efficiency between the golf ball the golf club head.Type: GrantFiled: February 15, 2002Date of Patent: November 12, 2002Assignee: Callaway Golf CompanyInventor: John B.

Publication number: 20020165040Abstract: A golf club head having a face section with a polymer surface can provide a more efficient impact between a golf ball and the golf club head. By utilizing a polymer surface with desired material properties of stress, strain and damping levels, the face section will incur higher strain and strain rate levels than the golf ball. These lower internal stresses within the golf ball yield a more efficient impact with a golf club head.Type: ApplicationFiled: May 7, 2002Publication date: November 7, 2002Applicant: Callaway Golf CompanyInventors: John B.

Patent number: 6471603Abstract: A contoured golf club face provides increased structural integrity for a given weight and size is described and shown along with a method for its design. The contoured golf club face includes a vertical stiffening region, a tapered horizontal stiffening region, four similar contoured quadrants of increasingly thinning material toward the center of each quadrant, and thickening regions at face/sole and face/crown intersection regions. The thicknesses of adjoining regions are gradually blended to provide a smooth contoured surface. The present golf club face is light weight, is structurally resistant to impact deformation, is resistant to initial and long-term failure, has its mass center located at its sweet spot, exhibits inertial axes which are aligned with vertical and horizontal axes (i.e. primary club force directions: ball impact force and club centrifugal force directions), and produces acoustical tones.Type: GrantFiled: December 3, 1999Date of Patent: October 29, 2002Assignee: Callaway Golf CompanyInventor: John B.

Patent number: 6348013Abstract: A compliant golf club head permits a more efficient impact between a golf ball and the golf club head. By allowing a face section of the golf club head to flex rearwardly during impact with the golf ball internal stresses within the golf ball are reduced to yield a more efficient impact. A thin wall section is located generally parallel with the face and near the junction with a top, bottom heel and toe sections to allow the face of the golf club head to flex rearwardly.Type: GrantFiled: December 30, 1999Date of Patent: February 19, 2002Assignee: Callaway Golf CompanyInventor: John B.
