Patent number: 10321871Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining sleep stages and sleep events using sensor data. In some implementations, sensor data is obtained over a time period while a person is sleeping. The time period is divided into a series of intervals. Heart rate and changes in the heart rate are analyzed over the intervals. Based on the analysis of the heart rate changes, sleep stage labels are assigned to different portions of the time period. An indication of the assigned sleep stage labels is provided.Type: GrantFiled: August 26, 2016Date of Patent: June 18, 2019Assignee: Awarables Inc.Inventors: Amrit Bandyopadhyay, Gilmer Blankenship, Raghu Upender, Madhvi Upender, Chris Giles

Patent number: 9664521Abstract: 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: GrantFiled: April 25, 2014Date of Patent: May 30, 2017Assignee: TRX Systems, Inc.Inventors: Benjamin E. Funk, Jared Napora, Kamiar Kordari, Ruchika Verma, Amrit Bandyopadhyay, Carole Teolis

Patent number: 9448072Abstract: 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 (e.g., inertial navigation and signal-based methods) may be provided as input to a mapping application. The mapping application may generate position estimates for trackees using a suite of mapping tools to make corrections to the tracking data. The mapping application may further use information from building data, when available, to enhance position estimates. Indoor tracking methods including, for example, sensor fusion methods, map matching methods, and map building methods may be implemented to take tracking data from one or more trackees and compute a more accurate tracking estimate for each trackee.Type: GrantFiled: August 6, 2008Date of Patent: September 20, 2016Assignee: TRX Systems, Inc.Inventors: Amrit Bandyopadhyay, Daniel Hakim, Benjamin E. Funk, Eric Asher Kohn, Carole A. Teolis, Gilmer Blankenship

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
