1. A method comprising:
- detecting motion by an inertial sensor included in a mobile device;
determining, by the mobile device, whether the motion has a motion signature indicative of a user activity that the mobile device is configured to monitor;
when the motion does not have a motion signature of a user activity that the mobile device is configured to monitor, entering a sleep mode.

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.

5. A method for a mobile device comprising:
-
receiving acceleration data that meets stepping criteria from an accelerometer included in the mobile device; incrementing a step count in a step count buffer; when at least one of a) the step count is below a step count threshold, or b) a current user cadence fails to match a step cadence of a user profile, using a default step cadence window to identify a time frame within which to monitor for a next step; and when the step count is at or above the step count threshold, determining a dynamic step cadence window and using the dynamic step cadence window to identify the time frame within which to monitor for the next step. - View Dependent Claims (6, 7, 8, 9, 10, 11)
