Claims19
A mobile communication device comprising:
- an optical rotary device comprising an optical sensor configured to sense rotation of the optical rotary device;
- and
- a processor coupled to the optical rotary device, the processor configured to determine whether the optical rotary device is rotating via the optical sensor and remove power from the optical rotary device when it is determined that the rotary device is not rotating.
A method for conserving power in a device that includes an optical rotary device, comprising:
- determining whether the optical rotary device is rotating via the optical sensor;
- and
- removing power from the optical rotary device when it is determined that the rotary device is not rotating.
