  • Patent number: 9080882
    Abstract: A mobile device can receive OCR library information associated with a coarse position. The coarse position can be determined by the mobile device, or by a network server configured to communicate with the mobile device. A camera on the mobile device can obtain images of human-readable information in an area near the coarse position. The view finder image can be processed with an OCR engine that is utilizing the OCR library information to determine one or more location string values. A location database can be searched based on the location string values. The position of the mobile device can be estimated and displayed. The position estimated can be adjusted based on the proximity of the mobile device to other features in the image.

  • Patent number: 9081079
    Abstract: Various methods, apparatuses and articles of manufacture may be implemented for use in one or more computing platforms to adaptively provide and/or obtain indoor navigation assistance data (INAD) update(s) for use by a mobile device. An INAD update may, for example, comprise a subset of INAD available for an indoor environment. Such a subset may be determined based, at least in part, on a bounded region in an electronic map of the indoor environment. Such a bounded region may, for example, have a shape and/or a size based, at least in part, on at least one parameter indicative of a motion state of the mobile device.
