Claim Text:
1. A mobile device comprising: an inertial sensor configured to provide inertial sensor data; a processing device; and a storage device storing computer-executable instructions which, when executed by the processing device, cause the processing device to: identify that the mobile device is within an entrance anchor location associated with a dead zone; activate the inertial sensor in response to arrival of the mobile device at the entrance anchor location; identify that the mobile device is within an exit anchor location associated with the dead zone; determine that a delay has elapsed since identifying that the mobile device is within the exit anchor location, the delay comprising a threshold amount of time during which the mobile device is not within the dead zone; and deactivate the inertial sensor in response to determining that the delay has elapsed and the device has not re-entered the dead zone.
