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 unitary apparatus configured to be worn by a user, comprising:
a power supply; a sensor configured to capture acceleration data from the appendage of the user; an analysis processor; a sampling rate processor; and a non-transitory computer-readable medium comprising computer-executable instructions that when executed by the analysis processor perform at least: receive acceleration data captured by the sensor; determine a first sampling rate of the captured sensor data, wherein the sampling rate processor is configured to select the first sampling rate with a value below an upper sampling rate in order to reduce power consumption by the analysis processor from the power supply during sampling; sampling the data captured by the sensor at the determined first sampling rate; and classifying the acceleration data into an activity category selected from a plurality of activity categories being performed by the user.
