Patent number: 9297658Abstract: Disclosed herein is the use of Wi-Fi based location estimates of a mobile device to provide global offset corrections (including automated initialization) and enhanced navigation accuracy through delivery of heading corrections. In an embodiment, dead reckoning tracking data may be received for a tracked subject. The tracking data includes a plurality of tracking points forming a tracking path of the tracked subject. A Wi-Fi position system location estimate is also obtained. The Wi-Fi position system location estimate is one of a plurality of Wi-Fi position system location estimates correlated to the dead reckoning tracking data. And a tracking related parameter is determined based on the correlation of the dead reckoning tracking data to the Wi-Fi position system location estimate.Type: GrantFiled: June 12, 2013Date of Patent: March 29, 2016Assignee: TRX Systems, Inc.Inventors: Amrit Bandyopadhyay, Daniel Hakim, Carole Teolis

Publication number: 20150285638Abstract: A system and method for recognizing features for location correction in Simultaneous Localization And Mapping operations, thus facilitating longer duration navigation, is provided. The system may detect features from magnetic, inertial, GPS, light sensors, and/or other sensors that can be associated with a location and recognized when revisited. Feature detection may be implemented on a generally portable tracking system, which may facilitate the use of higher sample rate data for more precise localization of features, improved tracking when network communications are unavailable, and improved ability of the tracking system to act as a smart standalone positioning system to provide rich input to higher level navigation algorithms/systems. The system may detect a transition from structured (such as indoors, in caves, etc.) to unstructured (such as outdoor) environments and from pedestrian motion to travel in a vehicle.Type: ApplicationFiled: April 25, 2014Publication date: October 8, 2015Applicant: TRX Systems, Inc.Inventors: Benjamin E. Funk, Jared Napora, Kamiar Kordari, Ruchika Verma, Amrit Bandyopadhyay, Carole Teolis

Patent number: 9046373Abstract: A system and method for locating, tracking, and/or monitoring the status of personnel and/or assets (collectively “trackees”), both indoors and outdoors, is provided. Tracking data obtained from any number of sources utilizing any number of tracking methods may be provided as input to a mapping application. The mapping application generates position estimates for trackees using a suite of mapping tools to make corrections to the tracking data. The mapping application further uses information from building data, when available, to enhance position estimates. Indoor tracking methods including sensor fusion methods, map matching methods, and map building methods may be implemented compute a more accurate tracking estimate for trackees. Outdoor tracking methods may be implemented to enhance outdoor tracking data by combining tracking estimates such as inertial tracks with magnetic and/or compass data if and when available, and with GPS, if and when available.Type: GrantFiled: September 14, 2012Date of Patent: June 2, 2015Assignee: TRX Systems, Inc.Inventors: Amrit Bandyopadhyay, Daniel Hakim, Benjamin E.

Patent number: 8930163Abstract: 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 14, 2013Date of Patent: January 6, 2015Assignee: TRX Systems, Inc.Inventors: Kamiar Kordari, Benjamin Funk, Jared Napora, Ruchika Verma, Carole Teolis, Travis Young

Publication number: 20140278060Abstract: 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: ApplicationFiled: February 12, 2014Publication date: September 18, 2014Applicant: TRX Systems, Inc.Inventors: Kamiar Kordari, Benjamin Funk, Carole Teolis, Jared Napora, John Karvounis, Dan Hakim, Christopher Giles, Carol Politi
