Abstract
Golf performance and equipment characteristics may be determined by analyzing the impact between a golf ball and an impacting surface. In some examples, the impacting surface may be a golf club face. The impact between the golf ball and the surface may be measured based on sound and/or motion sensors (e.g., gyroscopes, accelerometers, etc.). Based on motion and/or sound data, various equipment-related information including golf ball compression, club head speed and impact location may be derived. Such information and/or other types of data may be conveyed to a user to help improve performance, aid in selecting golf equipment and/or to insure quality of golfing products.
Claims21
A non-transitory computer readable medium storing instructions that, when executed, cause an apparatus to:
- receive first sound data generated from an impact of a first golf ball with a golf club swung by a user;
- receive second sound data generated from an impact of a second golf ball with the golf club swung by the user,
- analyze the impact data to:
- determine whether a predefined frequency is included in the first sound data;
- determine whether the predefined frequency is included in the second sound data;
- determine a head speed of the golf club based on whether an audio signal of the predefined frequency is included in the first sound data and the second sound data and generate an output specifying one or more characteristics of the impact.
A method comprising:
- receiving first sound data generated from an impact of a first golf ball with a golf club swung by a user;
- receiving second sound data generated from an impact of a second golf ball with the golf club swung by the user,
- analyzing the impact data to:
- determine whether a predefined frequency is included in the first sound data;
- determine whether the predefined frequency is included in the second sound data;
- determine a head speed of the golf club based on whether an audio signal of the predefined frequency is included in the first sound data and the second sound data and generating an output specifying one or more characteristics of the impact,
- wherein the first golf ball is differently constructed than the second golf ball.
A method comprising:
- receiving first sound data generated from an impact of a first golf ball against a face of a golf club, wherein the data includes an audio signal;
- receiving second sound data generated from an impact of a second golf ball against the face of the golf club, wherein the first golf ball is differently constructed than the second golf ball;
- analyzing each of the first sound data and the second sound data to determine whether a specified frequency is included in each of the first sound data and the second sound data;
- and
- generating an output based on the analysis of the first sound data and second sound data, the output including a determined golf club head speed.
