DYNAMIC SAMPLING

摘要

A wrist-worn athletic performance monitoring system, including an analysis processor, configured to execute an activity recognition processes to recognize a sport or activity being performed by an athlete, and a sampling rate processor, configured to determine a sampling rate at which an analysis processor is to sample data from an accelerometer. The sampling rate processor may determine the sampling rate such that the analysis processor uses a low amount of electrical energy while still being able to carry out an activity classification process to classify an activity being performed.

1. A non-transitory computer-readable medium comprising computer-executable instructions that when executed by a processor is configured to perform at least:
receive acceleration data representing movement of an appendage of a user at a sampling rate processor located on a device configured to be worn on an appendage of a human, wherein the acceleration data was obtained by an accelerometer located on the device while the accelerometer is operating at a first sampling rate; based, at least in part, on the received acceleration data itself, classify the acceleration data into one of a plurality of activity categories representing an activity being performed by the user; and based upon at least the classified activity category, selecting a second sampling rate from a plurality of sampling rates for operating the accelerometer during the activity being performed by the user.
