Golf clubs and golf club heads having digital lie and/or other angle measuring equipment
First Claim
1. A non-transitory computer-readable medium having computer-readable instructions that when executed by a processor perform a method comprising:
- collecting angular rate data from three gyroscopes located within a golf club head, wherein each of the three gyroscopes measures rate data along a different orthogonal axis;
collecting data from three accelerometers, wherein each accelerometer collects data along one of the three orthogonal axes associated with the gyroscopes;
upon determining that an impact event has occurred, identifying data for processing;
processing the identified data, wherein the processing comprises;
resolving the identified angular rate data to obtain space-fixed coordinates;
calculating roll and pitch data;
utilizing the roll and pitch data and the space-fixed coordinates to calculate at least one of a lie angle, a club face angle, and a loft angle of the club head; and
wherein at least a portion of the roll and pitch data are calculated using the formula;

Abstract
Golf club heads having sensors configured to measure one or more swing parameters are provided. The golf club head may include several gyroscopes and accelerometers. In one embodiment, the club head contains three gyroscopes that measure angular rate data along different orthogonal axes. At least one gyroscope may an analog gyroscope. Accelerometers may provide data regarding the three orthogonal axes associated with the gyroscopes. The club head may further include software and/or hardware that perform computer-executed methods for determining one or more swing parameters. Exemplary club heads may include a display device for displaying an output of the swing parameter(s). Further aspects of the invention relate to novel methods and algorithms for calculating measurements relating to the swing parameters.
