  • Biased control unit
    Patent number: 11753888
    Abstract: A control unit includes a rotatable tubular body that rotates around a spindle. A torque transfer unit may be attached to the tubular body and the spindle. A force applied to the torque transfer unit by a biasing element may control a first torque applied by the tubular body to the spindle. The first torque is independent of a rotational velocity of the tubular body. A second torque is applied to the spindle with a torque generator, the second torque controlling the net torque. Controlling the net torque allows the absolute orientation of the control unit to be controlled.
    Type: Grant
