Title:
METHOD AND APPARATUS FOR POWER SAVING SCHEME IN A LOCATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2014/121431
Kind Code:
A1
Abstract:
An approach is provided for providing efficient power saving schemes for a device and any associated sensors thereon while allowing for various levels of functionalities. A device determines a distance from a location of a device on a route to a checkpoint location on the route based, at least in part, on mapping data associated with the route. Then the device causes an initiation of a sleep mode of operation for at least one location sensor associated with the device. Further, the device causes an initiation of an active mode of operation for the at least one location sensor based, at least one in part, on a determination that the device has substantially traveled the distance, a portion of the distance, or a combination thereof.
