TRX Systems is pleased to announce that we have been awarded patent 9,395,190, Crowd Sourced Mapping with Robust Structural Features. This newest patent complements two patents TRX was awarded in May (9,322,648 & 9,297,658), enhancing IP protection for the NEON indoor location technology.
TRX delivers location and mapping services for industrial, public safety, defense and other applications using platforms with embedded low cost sensors (wearables, cellular devices). These sensors have the benefit of delivering location everywhere - not just in buildings with beacons or other networked infrastructure. However, without corrections, low cost sensors (e.g., those typically found in cellular devices) that are inherently subject to inertial drift, magnetic interference, and other error, would provide severely degraded information and subsequently poor location accuracy over any reasonable durations indoors.
The NEON Location Assistance Data provides effective 3D navigation map information provides constraints or corrections for the sensor data, enabling delivery of robust location estimates. The NEON Location Assistance Databsae consists of a database of geo-referenced, uniquely described features in the multi-dimensional sensor space (e.g., including structural, RF, and magnetic data) that are collected automatically as a person walks through a building. The features collected are sent to TRX’s location assistance data server where the new features are merged into the global map. The feature information can be used to create structural building models and signature maps as one or more tracked subjects traverses a building, and these maps are used to improve 3D user location estimates as user's operate within buildings, underground, and in other environments wihtout access to reliable GPS.
The NEON location and mapping service is being extended to create a global database of indoor navigation maps ("location assistance data") through crowd-sourcing and data fusion technologies. These navigation maps enable improved indoor location and heading accuracy by providing critical location corrections for any customers interested in sharing such location assistance data.
TRX Systems has a total of 13 patents in the U.S. as well as 12 from other countries protecting its unique approaches towards delivering ubiquitous location.
