Abstract
A mobile device operable in multiple navigation modes and includes navigation devices, a mode selection module, and a power management module. The navigation devices provide respective data associated with at least one of movement, a position, and a location of the mobile device. Each of the navigation devices is individually operable in an active mode and at least one of an inactive mode and a sleep mode. The mode selection module receives the respective data and selects one of the navigation modes based on the data received from one of the navigation devices. Each of the navigation modes corresponds to different ones of the navigation devices operating in the active mode. The power management module, based on the selected one of the navigation modes, transitions the navigation devices between the active mode and the at least one of the inactive mode and the sleep mode.
