Maybe so, but somewhat related.  Anyhow that's how they did it.

I was just trying to suggest that the device might provide solutions for
other problems.

 In 1983 and 1984 I had a consulting business repairing Diamond egg
processing equipment.  I repaired all the electronic boards and took
care of the electrical and mechanical problems the full time mechanics
couldn't handle.

The three plants I worked for in Boulder, Parker, and Hudson processed
all of the eggs for King Sooper, Safeway, and Albertson's respectively,
in Colorado.

The CMOS logic boards crapped out all the time.  They had been sending
them to California for $25 flat rate repair or having mechanics replace
scooted 4000 series chips until the egg packer worked right while trying
to run production.

I built a test fixture I could plug the boards into and simulate the egg
packer.  Later I wrote a Forth program for my VIC-20 that acted as a
slow logic analyzer.  Diamond's design had a race condition problem in
the shift registers that remembered whether an egg carton should be
closed if had been detected that it did not have a full dozen eggs in
it.  I later came up for a fix for it.

Then we were going to use a linear photo detector to detect checks and
cracked eggs to replace the four human candlers behind black curtains
bending over 24 300 watt halogen lights as eggs rolled over them.

That was all before the PIC and other microcontroller.
