1. A method of monitoring human activity using an inertial sensor, comprising:
- continuously determining an orientation of the inertial sensor;
assigning a dominant axis;
updating the dominant axis as the orientation of the inertial sensor changes; and
counting periodic human motions by monitoring accelerations relative to the dominant axis.

Abstract
A method for monitoring human activity using an inertial sensor includes continuously determining an orientation of the inertial sensor, assigning a dominant axis, updating the dominant axis as the orientation of the inertial sensor changes, and counting periodic human motions by monitoring accelerations relative to the dominant axis.

6. A method of monitoring human activity using an inertial sensor, comprising:
-
running a device that includes the inertial sensor in a non-active mode, in which periodic human motions are buffered; switching the device from the non-active mode to an active mode, after identifying a number of periodic human motions within appropriate cadence windows; and during the active mode, counting each of the periodic human motions to enable the monitoring of human activity. - View Dependent Claims (7, 8, 9, 10)

11. An inertial sensor based device, comprising:
-
a dominant axis logic, to continuously determine an orientation of a device, to assign a dominant axis, and to update the dominant axis as the orientation of the device changes; and a counting logic to count periodic human motions by monitoring accelerations relative to the dominant axis. - View Dependent Claims (12, 13, 14)

15. A device including an inertial sensor, comprising:
-
a counting logic, to identify and count periodic human motions; a mode logic, to switch the device from a non-active mode to an active mode after a number of periodic human motions are detected within appropriate cadence windows by the counting logic; and a buffer, to buffer periodic human motions when the device is in the non-active mode. - View Dependent Claims (16, 17, 18, 19, 20)
