A glass substrate and a shadow mask are put tightly together by inserting the glass substrate between a magnet and the shadow mask made of magnetic material. The non-volatile memory has a pseudo pass function of returning a pass as a status even if a bit error reaching allowable number of bits occurs after at least one of a write or erase sequence is completed. In one embodiment, multiple sensors sense, in alternative ways, a parameter that corresponds to a physical state of interest. The generated ingress packet hash values and the egress packet hash values are then compared. Desirable processing improvements can be obtained with the solution processible hardmasks. During a subsequent bending operation, pressure values resulting from this nomogram are applied to the compensation cylinders according to the forces measured at the side frames.
