Abstract: In a method of associating a single entity with multiple electronic devices, a server accesses user data collected via internet communications with a plurality of electronic devices. Each item of user data includes a location signature and a unique identifier. The server determines an intersection of location between two electronic devices of the plurality of electronic devices based on the user data accessed from the two electronic devices. The user data is accessed from a first of the two electronic devices has a first unique identifier that is different than a second unique identifier of the user data accessed from a second of the two electronic devices. Based on the intersection of location, a single entity is associated with both the first unique identifier and the second unique identifier.

Abstract: Systems and methods are disclosed for determining location information for a portable device by identifying interactions indicating proximity between the user and a plurality of items. Each item may be associated with a known location to establish anchor points such that a route traversed by the portable device may be generated from the established anchor points and motion sensor data output by the portable device.

Abstract: Systems and methods are disclosed for refining a coarse location determination by detecting patterns of motion sensor data that may be associated with predetermined locations. One or more geofeatures may be identified that cause a mobile device associated with a user to detect a distinguishable pattern of sensor data when the user interacts with the object. Accordingly, a coarse location may be refined using information associated with the geofeature, such as the location of the geofeature.

Abstract: Systems and methods are disclosed for providing a plurality of navigation solutions using a portable sensor device associated with a user. Motion sensor data may be used to derive a first navigation solution using the obtained sensor data under a first set of processing conditions navigation solution and to derive at least a second navigation solution using the sensor data under a second set of processing conditions, wherein the second navigation solution is refined as compared to the first navigation solution. As such, the second navigation solution may represent a more accurate or more complete solution, with the first navigation solution may represent a reduced expenditure of resources. The system includes the portable sensor device and optionally may include an auxiliary device associated with the user and/or remote processing resources.
