Patent number: 10267646Abstract: The present disclosure relates to a method and system for estimating varying step length for on foot motion (such as for example walking or running). The present method and apparatus is able to be used in anyone or both of two different phases depending on the embodiment. The first phase is a model-building phase done offline to obtain the nonlinear model for the step length as a function of different parameters that represent human motion dynamics, the model is built using a nonlinear system identification technique. In the second phase the nonlinear model is used to calculate the step length from the different parameters that represent human motion dynamics used as input to the model. These parameters are obtained from sensors readings from the sensors in the apparatus. This second phase is the more frequent usage of the present method and apparatus for a variety of applications.Type: GrantFiled: January 30, 2014Date of Patent: April 23, 2019Assignee: InvenSense, Inc.Inventors: Medhat Omr, Ahmed Wahdan, Jacques Georgy, Aboelmagd Noureldin

Patent number: 9562965Abstract: A two-filter based method of detecting and tracking a target that can track an unknown and time-varying number of targets, while keeping continuous track, even in scenarios with large number of false contacts or missing measurements, is provided. More specifically, a first filter provides target detection, a second filter provides target tracking of the detected targets, and a clustering technique that operates after the first filter. The first filter starts with a uniform distribution over the surveillance area and resets periodically after the clustering technique is run. When the clustering technique runs, it detects the clusters corresponding to the different targets and passes them to the second filter that tracks these targets.Type: GrantFiled: May 4, 2011Date of Patent: February 7, 2017Inventors: Jacques Georgy, Aboelmagd Noureldin

Patent number: 9423509Abstract: A moving platform INS range corrector (“MPIRC”) module and its method of operation for providing navigation and positioning information. The module comprises: means, such as a receiver, for receiving a first set of absolute navigational information from an external source (such as satellites in case of GNSS); an inertial sensor unit for generating a second set of navigational information at the module; and a transceiver, for receiving and/or transmitting signals and estimating distance measurement from a known position and receiving position coordinates. The navigational information is used by a processor programmed with a core algorithm, to produce a navigation solution (which comprises position, velocity and attitude). The system has the following attributes: the solution is produced seamlessly, even if one source of navigational information is temporarily out of service; the accuracy of the solution is assisted by use of distance and position coordinate measurement from a known position.Type: GrantFiled: June 27, 2011Date of Patent: August 23, 2016Assignee: Trusted Positioning Inc.Inventors: Jacques Georgy, Zainab Syed, Chris Goodall, Naser El-Sheimy, Aboelmagd Noureldin
