  • Magnetic-based motion monitoring for two objects sharing common joint
    Patent number: 11169001
    Abstract: A method is provided for monitoring relative positions of two objects sharing a common joint during motion between the two objects. An electromagnet is positioned on a first object and a magnetic sensor is positioned on a second object. The electromagnet's power or polarity is cycled during a monitoring session in accordance with a periodic schedule of alternating power-on/power-off periods or alternating-polarity periods, respectively. The magnetic sensor's output during one or more of the power-off periods or the alternating-polarity periods is used to remove environmental magnetic interference to dynamically determine the distance between the electromagnet and the magnetic sensor where the determined distance and the north pole orientation of the electromagnet are indicative of relative positions of the first object and the second object.
