Classification: CPC G | IPC G

Claim 17:
18. A display comprising:
a wheel configured to be rotated around an axis perpendicular to a rotating plane;
a plurality of light emitting circuits attached to the wheel;
a gyroscopic sensor mounted on the wheel and configured to measure angular velocity of the wheel while the wheel is being rotated;
an accelerometer mounted on the wheel and configured to measure acceleration of the wheel while the wheel is being rotated; and
a controller programmed to:
determine zero-crossings of a value of the acceleration resolved along the rotating plane;
determine the angular position of the wheel based on the measured angular velocity and the zero-crossings; and
set a display property of the plurality of light emitting circuits based on the angular position.
