    摘要: Systems, apparatus and methods are presented for sensing or estimating a tilt angle, in which a current flowing in an eccentric mass motor is sensed, and a detector circuit assesses the amplitude of a synchronous component of the motor current and provides an output signal or value indicating a tilt angle relative to a gravitational axis at least partially according to the amplitude of the synchronous component of the motor current.
