The next two Popular Science articles both mention Honeywell engineering manager Norman Stauffer, whose name is on most of the groundbreaking auto-focus patents, including the patent for the Visitronic system used in the Konica C35AF. At the time he worked in Denver; he retired from Honeywell in 1992 and today lives in Grand Lake, Colorado, where his hobby is taking astronomical pictures. You can buy his book, Sky Shots From Grand Lake, here.

(There's more about Stauffer's patents on the Minolta Maxxum 7000 page.)

This first Popular Science article appeared in the December 1977 issue:

The next article, from the Decenber 1980 issue, lists 6 other 35mm cameras that, like the Konica C35AF, use Honeywell's Visitronic system: Canon AF35M, Fujica Flash Auto Focus, Mamiya 135AF, Minolta Hi-Matic AF, Rolleimat AF, and Yashica Auto Focus.
