    Abstract: A method to find symmetries along curved paths in input scenes. The method may detect a curve in an input scene and one or more elements on that curve. The method may define and group points for the one or more element on the curve, and define a centroid for each group. The method may then parameterize a transformation in transformation space between each centroid pair in the input scene. The method may then extract transformation paths by clustering points. The method may create phantom objects in case of mirroring along curved paths to help detect the curved paths.

    Abstract: A semiconductor memory employs the redundancy memory technique and the error correction code technique and method of correcting errors. The method of correcting errors reads data bits and a checking bit from a predetermined unit of a first memory array such as a main memory array, and the data bits are checked based on the checking bit to determine if there is any error. If there is an error in the data bits, the checking bit is used to correct the error and the data bits together with the checking bit are written back to the predetermined unit. If there is still error in the data bits after the read-check-write process is repeated a predetermined number of times, the predetermined unit is marked as a faulty unit and the data bits together with the checking bit are written to a second memory array such as a redundancy memory array.

    Abstract: A motor controlling system is disclosed. The motor controlling system is integrated in an apparatus having roll-to-roll mechanism, and comprises a linear light source, N number of cameras and a modular electronic device. When a roll of continuous web material is discharged by an unwinding unit of the roll-to-roll mechanism so as to be further transferred to an inspection unit, the cameras are controlled by the modular electronic device to capture a plurality of time-consecutive material image frames. Subsequently, the modular electronic device conducts a defection inspection for a segment of the continuous web material by applying an image process to the material image frames. As a result, in case of there being at least one defect found, the modular electronic device stops a plurality of motors of the apparatus from running, thereby making the segment of the continuous web material be positioned on an inspection platform.
