Abstract: Flexible storage sheets of a laminar file assembly are sensed in multiple by stationary sensors. Resultant signals are used to control operation of a partitioning blade mechanism relative to randomly selected sheet interfaces and to verify integrity of such operation. Sheets unmasked by a cursor mask registered with the blade tip are sensed in multiple by stationary optics and photoelectronics. The photoelectronic signals are repeatedly sampled, staticized and counted by shifting and counting electronics. The count derived from each sample represents the instantaneous location of the blade tip relative to the sheets. The counts are used to indicate: sheet stability (e.g., for predictive or extrapolative control relative to continually moving sheets), instantaneous location of a specific sheet interface relative to the partitioning mechanism and/or integrity of a partitioning operation currently in progress. Due to the multiple sensing organization subject apparatus is virtually insensitive to transient error in the sensors or electronics. Errors are not cumulative since the count derived from each sample represents a complete information (addressing) entity.

Abstract: A system for computerizing changes to engineering drawings by separating graphical and textual information in a digital representation of a drawing so that desired changes can be made to the digital representation. Separation is accomplished by scanning the document and analyzing it element by element until all objects have been separated one from another. Special purpose circuitry is provided to test for connectivity between one state bits in a single row and adjacent one state bits in the directly neighboring row.
