| Method and System for Tracking Movement of a Person with Wearable Sensors | EP3946048A1 | 2023-12-07 | |
A method that enables the distinction of two movements that, despite having different characteristics, exhibit similar limb orientations. |
| Correction of Heading Errors of Inertial Measurement Units of a Motion Tracking System | US11774246B2 | 2023-10-03 | |
Method for correcting the mismatch between the actual movement and the one sensed by the inertial sensors due to magnetic disturbances and soft tissue artifacts. |
| Estimation or Verification of Distance of a Target with Angle of Arrival or Angle of Departure Data | US11726165B1 | 2023-08-15 | |
A method that utilizes wireless signals from different devices in specific spots to figure out how far something is from a main device by looking at the angles of these signals. |
| Method and system for determining a correct reproduction of a movement | US20230004236A1 | 2023-08-08 | |
Method for determining not only whether a physical therapy exercise was correctly performed but also the specificities of any incorrect movement that might have been attempted. This method and variations thereof are applicable to the vast majority of physical therapy exercises. |
| Determination of cause of disconnection of sensors of a motion tracking system | EP3984008B1
| 2023-05-17 | |
A method for determining if the cause of losing the connection to the motion trackers is the fact that the patient moved away from the tablet. |
| Wireless Connections Between Devices of Motion Tracking System and Authentication of a User Thereof | EP3993693B1 | 2023-04-05 | |
A method for establishing connections between the motion trackers and the tablet based on the variation of the values of signal strength of the motion trackers. The objective is to automatically discover the motion trackers assigned to the user in order to avoid the connection to other devices that could be nearby. |
| Gyroscope Drift Estimation and Compensation with Angle of Arrival of Electromagnetic Waves | US11609102B1 | 2023-03-21 | |
A method to estimate the drift that gyroscopes of Inertial Measurement Units (IMUs) accumulate over time so that the same may be compensated relative to the measurements of other gyroscopes or IMUs. |
| Magnetometerless detection of incorrect attachment and calibration of motion tracking system | EP3903065B1 | 2022-11-09 | |
Method for detecting and avoiding magnetic disturbances as well as perform body-to-sensor calibration (the process in which the difference between the limb orientation and the sensor orientation is estimated) without suffering from lack of accuracy due to magnetic disturbances. |
| Control of a Motion Tracking System by User Thereof | EP3953801B1 | 2022-06-29 | |
A method for distinguishing the patient’s voice in an environment were several people are speaking. |
| Method and system for determining a correct reproduction of a movement | US11372484B2
US20230004236A1 | 2022-06-28 | |
Method for determining not only whether a physical therapy exercise was correctly performed but also the specificities of any incorrect movement that might have been attempted. This method and variations thereof are applicable to the vast majority of physical therapy exercises. |
| Method and system for calibrating sensors | EP3847418B1 | 2022-01-12 | |
Method for assuring the accuracy of a motion tracking system throughout its usage without compromising the product experience. |
| Method and device for synchronizing data packets from embedded data sensors monitoring body motion of a patient | EP3804420B1 | 2021-12-15 | |
Technique to synchronize data blocks originating from multiple motion sensors without depending on an external synchronization source or requiring the user to execute a synchronization procedure. |
