there is a automation plant in the Sandpoint area that makes bar scan readers. as far as food processing stuff, you would be better employed in CDA. It has some very nice areas around it to commute from.
Maybe you’re thinking of Encoder Products Company on US-95 in Sagle? We drive by there all the time.

Also, McCallister Technical Services on Sherman in the heart of CdA. They do custom controls & automation work. I stopped in and talked to them a month ago — it’s a fascinating company.
