    Abstract: Methods and devices are described for providing localized secure navigation in conjunction with near field communication access control systems. In one potential embodiment, a mobile device such as a cell phone may communicate with a door access control point using near field communication to receive location access system information. The mobile device may then authorize download and execution of a local secure navigation module from a location access system using the location access system information for use in receiving location assistance data, based on an authentication level associated with the mobile device. Such location assistance data may be used by the local secure navigation module to provide location assistance when the mobile device is in a secure location. The location of the mobile device may then be tracked using at least the location assistance data and the communication with the door access control point.

    Abstract: Techniques for displaying navigation information on a mobile device are provided that include a method that includes obtaining an indication of a position and an indication of a direction associated with the mobile device, using the indication of the position, the indication of the direction, information regarding identities of POIs within a geographic region of interest, and information regarding areas associated with the POIs to determine at least one relevant POI, of the POIs, that is associated with the position and direction, and displaying at least one visual indication associated with each of the at least one relevant POI on the mobile device. The appearance of the at least one visual indication is dependent on at least one of a distance from the mobile device of the relevant POI associated with the visual indication or presence of a known physical barrier between the mobile device and that relevant POI.

    Abstract: A digital map having a routing path is created. Points in at least a majority of a linear length of the path may be constrained so that they are disposed substantially equidistant between structural features that are bounding navigable spaces in a structure. The creating of the path may include selecting a connected component corresponding to some or all of the navigable spaces. A morphological process may be performed on the connected component to create the path.

    Abstract: Methods, systems, computer-readable media, and apparatuses for image-based status determination are presented. In some embodiments, a method includes capturing at least one image of a moving path. At least one feature within the at least one image is analyzed and based on the analysis of the at least one feature, a direction of movement of the moving path is determined. In some embodiments, a method includes capturing an image of an inclined path. At least one feature within the image is analyzed and based on analysis of the at least one feature, a determination is made whether the image was captured from a top position relative to the inclined path or a bottom position relative to the inclined path.
