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.
Method for assuring the accuracy of a motion tracking system throughout its usage without compromising the product experience.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
