Abstract: A novel voice-enabled directory look-up system is disclosed. In one embodiment, an operator reads the first few characters from each of the first and last names of a mail addressee. The system captures the speech as an audio signal, which is parsed into character position segments. The system determines one or more candidate characters that might have resulted in the audio signal for each character position segment. The system then expands the list of candidate characters for at least one character position to include one or more characters that sound like the original candidate characters for that character position. The candidate characters for the respective character positions are composed into a regular expression, which is applied using an inexact string matching look-up routine to a directory of records. Records with the best matches are returned in a menu for the operator. The operator selects the desired record from the menu.

Abstract: An engraver including an automatic tool changer and verification system for changing engraving tools on engraving heads. The engraver includes a turret having a plurality of workholders for holding a plurality of replacement tools. Some of the workholders are empty for replacing a worn tool from an engraving head on the engraver. When it is desired to change a tool on the engraving head, an empty tool holder is indexed to a tool changing position opposite the engraving head whereupon the worn tool is transferred from the engraving head to the tool changer. Thereafter, the tool changer is indexed to a position where a replacement tool is situated in opposed relationship with the engraving head. The tool changer includes a pneumatic system for causing the worn tools and replacement tools to be transferred between the engraving head and the tool changer. The engraver also utilizes a tool verification routine for verifying that a tool on the engraving head is the correct tool and/or is not defective.

Abstract: An engraving system for engraving printing cells in a gravure printing cylinder uses a video camera for feedback control of printing cell width. A setup procedure for the engraving system involves engraving an isolated test cell and a series of adjacent test cells, the latter being engraved under steady state engraving conditions. The isolated test cell is located through a search sequence which establishes a strobe control count for a strobe trigger unit. The strobe control count then is adjusted for steady state engraving by acquiring and centering a steady state test cell. Cell width is measured by creating video runtable sets for a plurality of overlapping video boxes and finding a maximum connected run length which meets predetermined acceptance criteria.
