  • Patent number: 9319868
    Abstract: A system for detecting state transitions when apparatuses move between significant places or routes without having to employ high resolution, and high energy cost, localization technologies. Apparatuses may receive position information via lower resolution/lower energy cost localization resources, and this information may be used to determine whether the current position of the apparatus corresponds to a significant place or route. If the apparatus is determined to be positioned in a significant place or route, a further determination may be made as to whether at least one second level classifier exists for the significant place or route. Second level classifiers may be utilized to determine when apparatuses transition from one state (e.g., one significant place or route) to another. Upon detection of a state transition based on the second level classifier, a new localization configuration may be applied in the apparatus.
