Patent number: 8430762Abstract: The present invention relates to a method for conserving power for a shot tracking device for attachment to a golf club. The method involves transmitting a plurality of signals from a shot tracking device attached to a golf club. The shot tracking device is enabled to determine that a threshold number of signals has been transmitted by the shot tracking device and a receipt signal has not been received by the shot tracking device, which in turn deactivates the shot tracking device until a predetermined event occurs.Type: GrantFiled: December 15, 2010Date of Patent: April 30, 2013Assignee: Callaway Golf CompanyInventors: Joseph Balardeta, Scott Denton

Patent number: 8425340Abstract: The presented invention relates to a method for determining the effectiveness of a golfer's swing without the requirement of the club head making contact with a golf ball. More specifically, the present invention relates to a measurement and analysis system comprising a first module that attaches to the club head and captures measurement receiver signal strength data during the entire swing time line and may capture motional data on same time line, further first module wirelessly communicates bi-directionally with a second module that is further connected to a user interface device and computational engine where feedback results are derived and conveyed to the golfer. The system provides comprehensive feedback for a swing characterization time line referenced to the spatial domain using receiver signal strength measurements that may be in combination with motional and dynamics orientation measurements.Type: GrantFiled: November 6, 2011Date of Patent: April 23, 2013Assignee: Golf Impact LLCInventor: Roger Davenport

Publication number: 20130090180Abstract: A golf practice mat includes an impact sensor disposed in a vicinity bounding the location of where a golf ball would be placed for striking. The golf practice mat may also include, for example, a “crosshair” target imprint that is disposed on a golf club impact sensor portion of the practice surface and indicates the point/line of contact that the club face should hit the ground after the ball has been struck with the club head in a descending blow. A microcontroller receives and analyzes the output of the impact sensor and generates a display/output message that is coupled to a display that is, for example, embodied on the golf practice mat to provide user shot-related feedback. The display may indicate, for example, the user's golf club, the estimated distance the ball will travel depending upon the impact data analyzed, the club chosen by the user, input backswing data and/or a three-dimensional simulation of the resulting golf stroke.Type: ApplicationFiled: October 12, 2012Publication date: April 11, 2013Inventor: Mark Edward Nusbaum

Patent number: 8414411Abstract: An instrumented golf club system and methods are disclosed. A variety of golf swing parameters are measured by the instrumented golf club and wirelessly transmitted to a portable computer device. The portable computer device generates a user interface that displays the golf swing parameters against preferred golf swing parameters. The instrumented golf club system allows a golfer to receive feedback in real time while playing golf.Type: GrantFiled: May 6, 2010Date of Patent: April 9, 2013Assignee: Nike, Inc.Inventors: John T. Stites, Gary Tavares, Carl Madore, Mike Kelly, Raymond J. Sander, Jeffrey A. Hadden, Jeffrey R. Held, Garrick L. Maenle, Gregory S. Kramer, Chad E. Bouton, Clifford N. Dodson, Patrick K. Hoffman

Publication number: 20130079171Abstract: A putting stroke training system identifies a preferred putting stroke and facilitates training for a golfer to repeat the preferred putting stroke. The training system includes a grid box with a fixed side wall and a movable side wall. The movable side wall is positionable relative to the fixed side wall into alignment with the preferred putting stroke. The training system also includes an alignment sensor attachable to a putter head. In some embodiments, the alignment sensor signals when the putter head deviates from the preferred stroke.Type: ApplicationFiled: November 19, 2012Publication date: March 28, 2013Inventor: Norman Douglas Bittner
