VERSATILE SENSORS WITH DATA FUSION FUNCTIONALITY
First Claim
1. A fitness sensing system configured to be supported by a subject, the fitness sensing system comprising:
- an intelligent activity monitor comprising an accelerometer;
a heart-rate sensor; and
a processor in communication with the accelerometer and heart-rate sensor, wherein the processor is configured to process data received from the accelerometer and heart-rate sensor to compute a fitness metric Fm value that comprises a ratio of a pace P of an activity performed by the subject and a heart-rate H of the subject performing the activity.

Abstract
Apparatuses and methods are disclosed for identifying with a single, small, intelligent activity monitor a particular type of activity from among a plurality of different activities. The monitor may include a multi-axis accelerometer and microcontroller configured to combine and process accelerometer data so as to generate features representative of an activity. The features may be processed to identify a particular activity (e.g., running, biking, swimming) from among a plurality of different activities that may include activities not performed by a human subject. An intelligent activity monitor may be configured to operate as a versatile sensor, or to operate in combination with a versatile sensor, to further receive and process physiological data and compute a fitness metric for a subject.
