Patent number: 7369158Abstract: The present invention is directed to a launch monitor system that measures flight characteristics of an object moving in a predetermined field-of-view. The system includes a support structure, a lighting unit, a camera unit disposed on the support structure, and a calibration assembly. The calibration assembly includes a calibration fixture and at least one telescoping member. A first end of the telescoping member is coupled to the support structure and a second end is contactable with or coupled to the fixture. In an extended position of the telescoping member, the calibration fixture is in the field-of-view of the camera unit. In a retracted position, the calibration fixture out of the field-of-view. The calibration fixture further includes contrasting markings. In another embodiment, the system includes a frame and the launch monitor is pivotally suspended from the frame so that it self-levels. The present invention further includes a method of calibrating a launch monitor having a calibration fixture.Type: GrantFiled: July 16, 2004Date of Patent: May 6, 2008Assignee: Acushnet CompanyInventors: William Gobush, Diane I.

Patent number: 6682441Abstract: Golf balls are disclosed having novel dimple patterns determined by the science of phyllotaxis. A method of packing dimples using phyllotaxis is disclosed. Phyllotactic patterns are used to determine placement of dimples on a golf ball. Preferably, a computer modeling program is used to place the dimples on the golf balls. Either two-dimensional modeling or three-dimensional modeling programs are usable. Preferably, careful consideration is given to the placement of the dimples, including a minimum distance criteria so that no two dimples will intersect. This criterion ensures that the dimples will be packed as closely as possible.Type: GrantFiled: November 15, 2002Date of Patent: January 27, 2004Assignee: Acushnet CompanyInventors: Douglas C. Winfield, Kevin M. Harris

Patent number: 6682442Abstract: Golf balls are disclosed having novel dimple patterns determined by a plurality of connected polygon regions. A method of packing dimples using the connected polygons is also disclosed. For each disclosed dimple pattern, connected polygons extend from a pole of the golf ball towards the parting line. Dimples are positioned on the golf ball surface according to the pattern of connected polygons and then the remaining space of the golf ball is filled with dimples. This results in a golf ball having a dimple pattern that has some uniformity but also some variance.Type: GrantFiled: February 8, 2001Date of Patent: January 27, 2004Assignee: Acushnet CompanyInventor: Douglas C.

Patent number: 6609983Abstract: Golf balls are disclosed having novel dimple patterns determined by polyhedrons and intersecting great circles that connect points on the polyhedral segments. A method of packing dimples according to positions of the polyhedron and the intersecting great circles is also disclosed. For each disclosed dimple pattern, dimples of varying size are positioned along the edges of a polyhedron and then dimples of varying size are positioned where great circles that connect points on the edges of the polyhedral segments intersect. Any remaining space on the golf ball surface is filled with dimples. This results in a golf ball having a dimple pattern that has some uniformity but also some variance.Type: GrantFiled: March 5, 2001Date of Patent: August 26, 2003Assignee: Acushnet CompanyInventor: Douglas C.

Publication number: 20030056567Abstract: The present invention discloses an apparatus and method for quantifying the stiffness of a golf ball or golf ball core that would be experienced during typical use (i.e., impact) while also measuring the contact time. Preferably, the invention comprises an air cannon for shooting an object horizontally against a block. The velocities of the object towards and away from the block can be measured by two light gates separated by a given distance. The contact time can also be measured by optical sensors located at the block. The measured times and calculated velocities can then be used to calculate the coefficient of restitution and contact time of the object. These quantities can be further used to gauge the dynamic stiffness and resilience of a golf ball, or portion thereof, typically under conditions of normal use.Type: ApplicationFiled: September 19, 2001Publication date: March 27, 2003Inventors: Laurent C.
