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 are configured to perform at least:
- collecting angular rate data from at least one gyroscope located within a golf club head,wherein the angular rate data comprises data along three different orthogonal axes;
collecting acceleration data from at least one accelerometer, wherein the accelerometer data comprises data along each of the three orthogonal axes associated with the gyroscope data;
after determining that an impact event has occurred, executing instructions comprising;
utilizing roll and pitch data and space-fixed coordinates to calculate at least one of a lie angle, a club face angle, and a loft angle of the club head.

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.
