Publication number: 20190383606Abstract: 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.Type: ApplicationFiled: August 29, 2019Publication date: December 19, 2019Inventors: John KARVOUNIS, Jared NAPORA, Benjamin E.

Publication number: 20190371054Abstract: Systems, methods and instructions for creating building models of physical structures is disclosed. The building model may be a collection of floors defined by outlines containing regions that may be offset relative to a main region, and a collection of connectors. Connectors may have connection points for tracking, routing and sizing. Connectors may indicate elevation changes through georeferenced structural features. Signal elements may also be features that provide corrections when tracking. Feature descriptors are data that describes the structural configuration and signal elements enabling them to be matched to previously collected data in a database. User interface elements assist a user of a tracking device in collecting floor information, structural features and signal features and validating certain collected information based on previously known information. The height of floors may also be inferred based on sensor data from the tracking device.Type: ApplicationFiled: May 31, 2019Publication date: December 5, 2019Inventors: Travis Young, Daniel Hakim, Daniel Franchy, Jared Napora, John Karvounis, Jon Fetter Degges, Tim Wang, Benjamin Funk, Carole Teolis, Carol Politi, Stuart Woodbury

Publication number: 20190271547Abstract: A location and mapping service is described that creates a global database of indoor navigation maps through crowd-sourcing and data fusion technologies. The navigation maps consist of a database of geo-referenced, uniquely described features in the multi-dimensional sensor space (e.g., including structural, RF, magnetic, image, acoustic, or other data) that are collected automatically as a tracked mobile device is moved through a building (e.g. a person with a mobile phone or a robot). The feature information can be used to create building models as one or more tracked devices traverse a building.Type: ApplicationFiled: April 17, 2019Publication date: September 5, 2019Inventors: Travis YOUNG, Kamiar KORDARI, Benjamin FUNK, Carole TEOLIS

Patent number: 10393543Abstract: Methods for calibrating a body-worn magnetic sensor by spinning the magnetic sensor 360 degrees to capture magnetic data; if the spin failed to produce a circle contained in an x-y plane fit a sphere to the captured data; determining offsets based on the center of the sphere; and removing the offsets that are in the z-direction. Computing a magnetic heading reliability of a magnetic sensor by determining an orientation of the sensor at one location; transforming the orientation between two reference frames; measuring a first vector associated with the magnetic field of Earth at the location; processing the first vector to generate a virtual vector when a second location is detected; measuring a second vector associated with the magnetic field of Earth at the second location; and calculating the magnetic heading reliability at the second location based on a comparison of the virtual vector and the second vector.Type: GrantFiled: July 13, 2017Date of Patent: August 27, 2019Assignee: TRX SYSTEMS, INC.Inventors: Benjamin E.

Patent number: 10352707Abstract: 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.Type: GrantFiled: July 14, 2017Date of Patent: July 16, 2019Assignee: TRX SYSTEMS, INC.Inventors: Kamiar Kordari, Benjamin Funk, Carole Teolis, Jared Napora, John Karvounis, Dan Hakim, Christopher Giles, Carol Politi

Patent number: 10215587Abstract: A method for detecting a human's steps and estimating the horizontal translation direction and scaling of the resulting motion relative to an inertial sensor is described. When a pedestrian takes a sequence of steps the displacement can be decomposed into a sequence of rotations and translations over each step. A translation is the change in the location of pedestrian's center of mass and a rotation is the change along z-axis of the pedestrian's orientation. A translation can be described by a vector and a rotation by an angle.Type: GrantFiled: March 8, 2013Date of Patent: February 26, 2019Assignee: TRX SYSTEMS, INC.Inventors: Kamiar Kordari, Benjamin Funk, Jared Napora, Ruchika Verma, Carole Teolis, Travis Young

Publication number: 20170363426Abstract: 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.Type: ApplicationFiled: August 7, 2017Publication date: December 21, 2017Inventors: Daniel HAKIM, Christopher GILES, John KARVOUNIS, Benjamin FUNK, Jared NAPORA, Carole TEOLIS
