1. A control device comprising:
- an electric motor;
an unbalanced weight positioned on a shaft of the electric motor; and
a controller configured to;
receive a signal from the electric motor, the signal being generated at electrical terminals of the electric motor during movement of the unbalanced weight on the shaft while the control device is in a low-power state in which the electric motor is not actively driven; and
selectively change a state of the control device responsive to the signal.

10. In a controller of a control device, a method of changing a state of the control device, the method comprising:
-
while the control device is set in a low-power state, triggering an interrupt responsive to detecting from a motor of the control device a voltage that is greater than a threshold voltage, the voltage being generated during movement of an unbalanced weight on a shaft of the motor; and setting the control device to a normal state responsive to the interrupt. - View Dependent Claims (11, 12, 13)

14. A game controller, comprising:
-
a rumble motor; a drive module configured to drive the rumble motor; a signal filter configured to receive input from the rumble motor; an amplifier configured to receive input from the signal filter; a comparator configured to receive input from the amplifier; and a controller configured to; selectively connect the rumble motor to the drive module and the signal filter via a switching element responsive to a state of the game controller; send an output signal to the drive module to drive the motor during a normal state; and receive an input signal from the comparator to selectively change the state of the control device responsive to the input signal during a low-power state. - View Dependent Claims (15, 16, 17, 18, 19)
