Patent number: 11875519Abstract: An integrated navigation solution is provided for a device within a moving platform. Motion sensor data from a sensor assembly of the device is obtained, optical samples from at least one optical sensor for the platform are obtained and map information for an environment encompassing the platform is obtained. Correspondingly, an integrated navigation solution is generated based at least in part on the obtained motion sensor data using a nonlinear state estimation technique, wherein the nonlinear state estimation technique uses a nonlinear measurement model for optical sensor data. Generating the integrated navigation solution includes using the sensor data with the nonlinear state estimation technique and integrating the optical sensor data directly by updating the nonlinear state estimation technique using the nonlinear measurement model and the map information. The integrated navigation solution is then provided.Type: GrantFiled: August 13, 2021Date of Patent: January 16, 2024Inventors: Medhat Omr, Abdelrahman Ali, Amr Al-Hamad, Jacques Georgy, Billy Cheuk Wai Chan, Dylan Krupity, Qingli Wang, Christopher Goodall

Patent number: 10837794Abstract: Systems and methods are disclosed for characterizing on foot motion of a user with a portable device by obtaining parameters sufficient to characterize the on foot motion of the user from multiple sensor assemblies. Each additional sensor assembly may be independent of each other. The characterization of on foot motion is provided by synthesizing the parameters from the sensor assemblies. Characterization of on foot motion may include detecting a step, estimating step length, or both.Type: GrantFiled: February 9, 2015Date of Patent: November 17, 2020Assignee: InvenSense, Inc.Inventors: Medhat Omr, Jacques Georgy, Aboelmagd Noureldin

Patent number: 10302435Abstract: The present disclosure relates to a method and system for providing and enhanced navigation solution of a device within a platform (such as for example person, vehicle, or vessel of any type), wherein the device is within the platform and may be strapped or non-strapped to the platform, wherein in case of non-strapped the mobility of the device may be constrained or unconstrained within the platform, wherein the enhancement of the navigation solution is through multiple sensor assemblies, wherein the multiple sensors assemblies are not necessarily all on the device, and wherein the multiple sensors assemblies are within the platform. This method works for a navigation solution utilizing measurements from sensors (such as for example, accelerometers, gyroscopes, magnetometers etc.) whether in the presence or in the absence of absolute navigational information (such as, for example, GNSS or WiFi positioning).Type: GrantFiled: September 17, 2014Date of Patent: May 28, 2019Assignee: InvenSense, Inc.Inventors: Medhat Omr, Jacques Georgy, Aboelmagd Noureldin

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: 9719787Abstract: The navigation solution of a device may be enhanced by perforating multiple pass smoothing. Forward and backward processing of the input data may be performed to derive interim navigation solutions. One or more quantities of the interim navigation solutions may be combined to smooth the quantities. At least one additional pass of forward and backward processing may then be performed using quantities of the navigation solution that were combined to enhance the interim navigation solutions. Next, at least one uncombined quantity of the navigation solution from the enhanced interim navigation solution is combined to provide an enhanced smoothed navigation solution. Additional passes may be performed to combine other quantities of the navigation solution as desired.Type: GrantFiled: February 26, 2016Date of Patent: August 1, 2017Assignee: InvenSense, Inc.Inventors: Jacques Georgy, You Li, Medhat Omr, Christopher Goodall, Hsui-Wen Chang
