Methods for Controlling Devices Along a Bindery Line

      Disclosed is a computer program for controlling different
devices along a demographic bindery line.  In a bindery line a number
of devices may exist along the bindery line for modifying or guiding
a book.  These devices may include:

o   Divert Gates
o   Ink Jet Printers
o   Verification Sensors
o   Card Inserters
o   Label Applicators

      Because these devices may be placed anywhere along the line,
their action may not be synchronized with the action of the pin
clock, which indicates when the line has moved forward one cycle.
Instead, a method is required that allows the device to be controlled
or read once per cycle, at a point in the phase of the cycle where
the device is config- ured or calibrated.

      In order to control a bindery device accurately, the position
of the line needs to be monitored at a high rate.  As a minimum, the
line position should be sampled at least 3 times per cycle of the
line.  In the current implementation, the sampling rate is every 20
milliseconds which translates to 10 samples per cycle for a 16 inch
centered line running at 300 books per minute.

      The basic means of controlling the device is to check the
position of the line encoder on each sample.  The line encoder
increases during the cycle, and is reset to zero at each pin clock.
Thus, when checking the encoder, and it is found to have exceeded the
configured value of the device, the devic...
