Methods and systems for transforming electric power between two or more portals. The system includes a forwarding service to receive an E-mail message for delivery to a recipient. , the softening point of which is lower than that of the polyester by 5\xb0 C. According to the edge detection parameters, including orientation, anisotropy and variance strength, the method determines a footprint and frequency response for the interpolation of the output pixel. A permanent magnet layer and an electrode layer are formed on the sides of the patterned magnetoresistance element.
