1. An apparatus comprising:
- a processor; and
memory storing computer readable instructions that, when executed, cause the apparatus to;
receive data generated from an impact of a golf ball against a face of a golf club, wherein the data includes motion sensor data from at least one of;
a gyroscope and an accelerometer;
wherein the motion sensor is mounted on the golf club below a center of gravity of the golf club;
analyze the impact data to determine one or more characteristics of the impact between the golf ball and the face of the golf club, including filtering the motion sensor data and generating a response spectrum from the filtered motion sensor data; and
generate an output specifying an impact location of the golf ball on the face of the golf club;
wherein analyzing the impact data further comprises comparing the response spectrum to a first reference response spectrum for a first location on a golf club face.

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.

10. A system for determining an impact location of a golf ball on a face of a golf club, comprising:
-
a motion sensor including at least one of a gyroscope or an accelerometer for generating motion sensor data relating to motion of the golf club; wherein the motion sensor is mounted on the golf club below a center of gravity of the golf club; a computing apparatus including a processor; memory storing computer readable instructions that, when executed, cause the computing apparatus to; receive data generated from an impact of a golf ball against a face of the golf club, wherein the data includes the motion sensor data generated by the motion sensor; analyze the motion sensor data from the impact to determine one or more characteristics of the impact between the golf ball and the face of the golf club, including filtering the motion sensor data, generating a response spectrum from the filtered motion sensor data; and generate an output specifying an impact location of the golf ball on the face of the golf club; and an output device providing at least one of visual, audio, textual, or haptic information relating to the impact location of the golf ball on the face of the golf club; wherein analyzing the motion sensor data from the impact further comprises (a) comparing the response spectrum to a first reference response spectrum for a first location on the face of the golf club and (b) comparing the response spectrum to a second reference response spectrum for a second location on the face of the golf club upon determining that the response spectrum does not match the first reference response spectrum. - View Dependent Claims (11, 12, 13, 14, 15, 16)
