Abstract: This disclosure provides techniques for the creation of maps of indoor spaces. In these techniques, an individual or a team with no mapping or cartography expertise can contribute to the creation of maps of buildings, campuses or cities. An indoor location system can track the location of contributors in the building. As they walk through indoor spaces, an application may automatically create a map based on data from motion sensors by both tracking the location of the contributors and also inferring building features such as hallways, stairways, and elevators based on the tracked contributors' motions as they move through a structure. With these techniques, the process of mapping buildings can be crowd sourced to a large number of contributors, making the indoor mapping process efficient and easy to scale up.

Abstract: Methods and systems are described for determining the elevation of tracked personnel or assets (trackees) that can take input from mounted sensors on each trackee (including barometric, inertial, magnetometer, radio frequency ranging and signal strength, light and GPS sensors), external constraints (including ranging constraints, feature constraints, and user corrections), and terrain elevation data. An example implementation of this method for determining elevation of persons on foot is described. But this method is not limited to computing elevation of personnel or to on foot movements.

Abstract: Disclosed herein are methods and systems for mapping irregular features. In an embodiment, a computer-implemented method may include obtaining tracking data that has dead reckoning tracking data for a tracked subject along a path and performing shape correction on the tracking data to provide a first estimate of the path.

Abstract: A method and apparatus for providing mapping data in a network are disclosed. For example, the method receives coordinate data from a customer mobile endpoint device, and processes the coordinate data against at least one existing map. The method then identifies a route associated with the coordinate data as a candidate new route if the route is not previously known on the at least one existing map.

Abstract: Disclosed herein are methods and systems for fusion of sensor and map data using constraint based optimization. In an embodiment, a computer-implemented method may include obtaining tracking data for a tracked subject, the tracking data including data from a dead reckoning sensor; obtaining constraint data for the tracked subject; and using a convex optimization method based on the tracking data and the constraint data to obtain a navigation solution. The navigation solution may be a path and the method may further include propagating the constraint data by a motion model to produce error bounds that continue to constrain the path over time. The propagation of the constraint data may be limited by other sensor data and/or map structural data.

Abstract: A system and method for receiving a geocode request for a location including a textual description of the location, selecting a test for geocoding the location, geocoding the location using the selected test and determining a bounding area around the location indicating at least one maximum distance range from the location.

Abstract: A least-cost path between a pair of nodes A and B of a network is realized by segmenting the network into three or more segments, with nodes A and B being in different ones of the segments, with the third or more other segments being interposed between the segments to which nodes A and B belong, concurrently process the different segment to identify paths and their associated costs, and processing results generated by the different processing units to compute the least-cost path. Advantageously, the segmenting is chosen to equalize the work load of the different processing units so that the units finish their task roughly at the same time.

Abstract: A secure system for creating digital receipts, while minimizing the amount of data that is encoded in the digital receipt. The digital receipt provides authentication for a transaction. A digital receipt may be printed in the form of a code. The digital receipt digitally encodes a transaction identification code, a transaction amount or number of units authorized, and a digital signature. The digital receipt may be scanned or read to verify the authenticity of the transaction.
