    • The present invention is such that a doll equipped with a plurality of auxiliary magnetic poles is inserted into a hermetically-sealed container filled with liquid and the container is circumferentially arranged with variable magnetic poles whose polarities are determined by electromagnets, whereby attraction or repulsion is applied on each portion of the doll. The polarity of each variable magnetic pole can be arbitrarily controlled by adjustment of direction of current flowing in the electromagnets to enable the doll in the container to be driven in various types of motions. Therefore, the motions of the doll can be expressed in various interesting types including dancing to the accompaniment of music without recourse to making the doll in a complicated robotic shape.

    • A light-emitting diode (LED) driver used to power at least one LED with an alternating current (AC) voltage source is provided. The LED driver includes a rectifying unit applying N-fold higher voltage than the voltage from the AC voltage source to the LED. The rectifying unit includes a first charging unit to charge a first voltage, and a second charging unit to charge a second voltage. The first voltage includes the voltage at the AC voltage source during a first half-cycle of one AC voltage cycle, and the second voltage includes the first voltage and the voltage at the AC voltage source during the second half-cycle of the AC voltage cycle. Accordingly, the LED driver may improve light-emitting efficiency and reduce flicker of LEDs.
