6. System and method for wireless positioning in wireless network-enabled environments. United States. 61/503,119. 2012/07/05.
Patent Status: Granted/Issued Year Issued: 2019
Inventors: Mohamed Atia and Aboelmagd Noureldin
This patent offers client/server-based system that dynamically estimates and continuously calibrates a fine radio map for indoor positioning without extra network hardware or prior knowledge of the area and without time-consuming offline surveys. A modified Bayesian regression algorithm is introduced to estimate a posterior signal strength probability distribution over all locations based on online observations from WLAN access points (AP). The significance of this research is based on a fast feature reduction algorithm developed to optimize the radio map to select the most informative APs. The system also provides reliable integrity monitoring. Two different experiments on IEEE 802.11 networks show that the dynamic radio map provides 2-3m accuracy, which is comparable to results of an up-to-date offline radio map.

Patent Status: Granted/Issued Year Issued: 2017
Inventors: Jacques Georgy and Aboelmagd Noureldin
An underwater multi-target tracking solution for multi-static active sonar systems is offered in this patent. The developed system is based on a novel Particle filtering-based multi-target tracking algorithm. The innovation of this method is based on two particle filters. The first is for target detection, and the second is for tracking the multiple detected targets by tracking the different clusters. A density-based clustering algorithm runs periodically on the first filter output and the new clusters are added in the sampling step of the second filter. The significance of this system is its ability to track number of unknown time-varying underwater targets. The method is also capable of keeping continuous tracks of the targets and working with a large number of false contacts.

Patent Status: Granted/Issued Year Issued: 2016
Inventors: Jacques Georgy and Aboelmagd Noureldin
This patent offers a robust integrated navigation system for land vehicles capable of providing reliable positioning even in challenging GPS environments. With a view to target a low-cost navigation solution, this system integrates GPS with a set of low-cost MEMS based gyroscopes and accelerometers (available in all present land vehicles) to bridge GPS outages. The development of the integrated navigation module is based on Particle filtering, which is a nonlinear filtering technique capable of accommodating arbitrary sensor characteristics, motion dynamics and noise distributions. Moreover, robust nonlinear models of MEMS sensor errors were developed to mitigate the effect of bias drifts and scale factor instabilities. This product has a significant impact on land vehicle positioning targeting continuous, reliable and accurate navigation in urban areas where GPS receivers suffer from satellite signals that are usually blocked or suffer from multi-path.
