This invention relates to the field of information reading, and more specifically, to an improved information reader in a validator which eliminates the requirement to insert an information source in a particular direction in an information reader. At least one transmission passage is defined in the patterned frame, the transmission passage extending from a base of the patterned frame to a face of the patterned frame. In response to detection of an error in a particular page of a particular block of the NVRAM array, only the particular page of the particular block is retired, such that at least two of the multiple memory blocks across which a particular one of the page stripes is distributed include differing numbers of active pages. The methods may then identify additional items within the additional activity records that are associated with this same input, and may establish similarity ratings for the two items, with the similarity ratings indicating a likelihood that documents respectively associated with the items contain synonyms. 0 kohm-cm is formed over the first IPD to a top surface of the conductive pillar.
