Patent number: 10508920Abstract: In an embodiment, a method and system are provided for determining a pedestrian position via dead reckoning on a portable device carried by the pedestrian (or “user”). The device has at least a processor, a 3D accelerometer, and a 3D gyroscope. The 3D accelerometer, and a 3D gyroscope are sampled to calculate device orientation, and then 3D accelerometer samples are gathered during a sensor time frame and an average step frequency is calculated. The user's speed and direction of movement are estimated and a device velocity is calculated relative to a prior device velocity via dead-reckoning. The estimated device velocity is corrected for drift and the pedestrian position is calculated based on the corrected estimated current device velocity.Type: GrantFiled: November 4, 2014Date of Patent: December 17, 2019Assignee: XSENS HOLDING B.V.Inventors: Giovanni Bellusci, Jeroen D.

Publication number: 20190331493Abstract: In an embodiment of the disclosed principles, a strap down integration (SDI) system includes a gyroscope that provides gyroscope data samples and an accelerometer that provides accelerometer data samples. A timing capture module associates a timestamp in a common time-base to data samples, and an SDI module linked to the timing capture module processes the timestamped data samples to produce orientation and velocity increments. In an embodiment, the SDI system also includes a priority buffer for storing the data stream produced by the timing capture module prior to provision of the data stream to the SDI module. The SDI module may output SDI motion increments at a time specified in an output request via an output request sample placed in the incoming data stream and having a timestamp in the common time-base.Type: ApplicationFiled: April 25, 2018Publication date: October 31, 2019Applicant: XSENS HOLDING B.V.Inventors: Giovanni Bellusci, Sanjay Bhandari, Raymond Zandbergen, Matteo Giuberti, Laurens Slot

Patent number: 10415975Abstract: A method of tracking the motion of a moving object having a plurality of linked segments is provided. The method uses a limited set of sensing units that are coupled to one or more of the segments to receive one or more sensor signals from the sensing units. Based on the sensor signals, the method estimates a 3D orientation and predicts a 3D position of the segments at a tracking module. The method further communicates the 3D orientation and the 3D position of the segments to a database module, and associates a pose of the object to the 3D orientation and the 3D position of the segments.Type: GrantFiled: January 9, 2014Date of Patent: September 17, 2019Assignee: XSENS HOLDING B.V.Inventors: Giovanni Bellusci, Hendrick J.

Patent number: 10222450Abstract: An integrated inertial motion capture system includes external position aiding such as optical tracking. The integrated system addresses and corrects misalignment between the inertial (relative) and positioning reference (external) frames. This is especially beneficial when it is not feasible to rely on magnetometers to reference the heading of the inertial system. This alignment allows effective tracking of yaw in a common reference frame for all inertial sensing units, even those with no associated positional measurements. The disclosed systems and methods also enable an association to be formed between the inertial sensing units and positional measurements.Type: GrantFiled: October 12, 2015Date of Patent: March 5, 2019Assignee: XSENS HOLDING B.V.Inventors: Giovanni Bellusci, Jeroen Hol, Per Slycke

Patent number: 9523576Abstract: A technique for calculating magnetic field information from a magnetic sensor employs a sensing unit containing the magnetic sensor and another sensor capable of providing a measure of change in orientation. The method includes sampling a magnetic field at points in time and sampling the other sensor at each point in time. The method then entails rotating to a common time instant the magnetic field samples using the orientation of the sensing unit estimated by means of the other sensing modality in order to eliminate variations between magnetic samples due to changes in orientation of the sensor unit within such time interval. The magnetic samples, corrected for the sensor rotation in such interval, are used to calculate magnetic field related information specific to the given time interval and the magnetic field related information is communicated to a receiver at a rate lower than the sample rate.Type: GrantFiled: September 17, 2012Date of Patent: December 20, 2016Assignee: XSENS HOLDING B.V.Inventors: Giovanni Bellusci, Pieter Laurens Slot, Hendrik Johannes Luinge

Patent number: 8981904Abstract: A method, controller and system in accordance with various aspects of the present disclosure facilitate reduced energy consumption in a motion sensing device having an inertial measurement unit (IMU), with a strap down integration unit, and an application processing unit (AP). The system and method include rounding velocity increments and orientation increments at the inertial measurement unit, thereby producing a remainder values. The remainder values are added to subsequent velocity increments and orientation increments prior to rounding of those values, and so on. In this way, while motion granularity is slightly decreased, there is no drift of integration errors over time.Type: GrantFiled: March 27, 2012Date of Patent: March 17, 2015Assignee: Xsens Holding B.V.Inventors: Hendrik Johannes Luinge, Giovanni Bellusci, Freerk Dijkstra
