There is provided a noise suppressing device for suppress a noise component included in an input signal. The method includes correlating the dimensions of a first set of at least one control pattern printed in a lithographic resist layer, measured at three or more locations on or within the pattern which correspond to differing dose, defocus and blur sensitivity. The idlers allow low-friction operation of the abrading system to be provided at the very high abrading speeds used in high speed flat lapping with raised-island abrasive disks. The token comprises out-of-band token communication means set to validate user authentication by establishing a communication channel between the token and the server, the communication channel bypassing the browser. The resiliency system retrieves the error correction information for the memory location and re-creates the data of the memory location. The printed circuit board has a recess in the area of the measuring opening, and the injection molding compound encloses the attachment area of the pressure cell on the printed circuit board.
