Claim 8:
9. An athletic activity monitoring system, comprising:
an article of sporting equipment; and
a sensor module physically coupled to the article, the sensor module comprising:
a sensor; and
a processor configured to:
determine an initial spatial orientation of the article based on data collected by the sensor;
determine a change in a spatial orientation of the article based on data collected by the sensor; and
determine an activity metric of the article based on the change in the spatial orientation of the article,
wherein the initial spatial orientation is based on an initial orientation of the sensor module with respect to an external coordinate system,
wherein the sensor comprises an accelerometer or a magnetometer, and
wherein the initial spatial orientation of the article and the change in the spatial orientation of the article are determined with respect to at least one of a gravity vector using the accelerometer or a magnetic field vector using the magnetometer.
