Abstract: This invention presented a universal de-interlacing method and system by the motion detection, the motion adaptive interpolation, the directional edge interpolation, the 3:2 pull-downed detection and the 3:2 Pull-Downed recovery. Four-field motion detection can detect the motion area and the still area. By cooperating with the motion adaptive interpolation and the directional edge interpolation the picture possesses the very clear quality, high contrast, and high resolution. The 3:2 pull-downed detection and the 3:2 Pull-Downed recovery can detect the 3:2 Pull-Downed movie sequence and recover the interlaced fields into a progressive frames universally without too much overhead of computational power.

Abstract: A motorcycle lock is provided which includes a lock body consisting of a metal casing and a lock unit fitted into the metal casing. The lock unit includes two locking plates at the top and a lock cylinder at the bottom, and a shackle having two annular grooves around two opposite ends thereof and respectively inserted into a respective hole on the metal casing and locked by the locking plates. Turning the lock cylinder in one direction causes the locking plates to move in the reverse directions for permitting the shackle to be removed from the lock body. Turning the lock cylinder in the reverse direction causes the stop blocks of the left and right locking plates to engage the annular groove on opposing ends of the shackle for holding down the shackle.
