  • FLEXIBLE TRACKER SYSTEMS
    Publication number: 20180256282
    Abstract: An apparatus and method for tracking the position of one or more connected rigid bodies using markers attached to the rigid bodies by flexible connectors. Systems based on this method are comprised of flexible connectors, a position tracking system and a data processing algorithm to determine the positions and orientations of the rigid bodies. Variations in the methods of attachment of the flexible connectors, the means by which flexibility in the connector is produced, and in the layout of the markers are presented.

  • Flexible tracker systems
    Patent number: 10010381
    Abstract: An apparatus and method for tracking the position of one or more connected rigid bodies using markers attached to the rigid bodies by laterally compliant connectors. Systems based on this method are comprised of laterally compliant connectors, a position tracking system and a data processing algorithm to determine the positions and orientations of the rigid bodies. Variations in the methods of attachment of the laterally compliant connectors, the means by which lateral compliance in the connector is produced, and in the layout of the markers are presented.
