Classification: CPC G  H | IPC G  H

Claim 11:
12. The user input device of claim 1 wherein the control system is further configured to:
receive revolutions-per-second (RPM) data corresponding to a free-wheeling friction associated with the wheel that is in rotation;
determine a rotational rate-of-decay of the wheel in rotation and a corresponding baseline resistance of rotation;
modulate an amount of electrical current supplied to the magnetizing coil in the electropermanent magnet assembly to change a torque curve for the wheel based on a difference between the rotational rate-of-decay and a reference rate-of-decay, the electropermanent magnet assembly providing a magnetic resistance to rotation of the wheel, and the torque curve providing one or more braking profiles for the wheel.
