摘要： An embodiment of the invention provides an AC motor that is driven by an AC voltage. The AC motor includes a motor coil, a switch circuit, a position detector and a controller. The motor coil receives the AC voltage to drive an axis of the motor. The switch circuit is coupled to the motor coil and controls a current passing through the motor coil. The position detector detects the position of a motor rotor to output a polarity signal. The controller controls the switch circuit according to the polarity signal and the AC voltage to make the current to be a first current with a first direction or a second current with a second direction.

摘要： Conic Section Compass (CSC) is a hand-held drawing device. It applies a mathematics concept. CSC can be used to draw circles, ellipses, parabolas, hyperbolas or make surface curvatures of these types. Given a specific mathematics formula of the mentioned curves, users can draw a well defined curve with CSC (just like a compass to drawing a circle).
