This volume collects three autonomous comparative analyses, each examining the comparison between the microbiological diagnostic device described in the Berretti Patent (IT 1,183,052 / US 4,643,974, Sclavo S.p.A., filed January 5, 1984) and a subsequent technological system that uses colored arcs as a visual cognitive tool. The three comparisons address: the arc indicators of the Boeing 767 EICAS (1982), the Apple Watch Activity Rings system (2015), and the HMDS of the Lockheed Martin F-35 (2015). Each comparison demonstrates that the Berretti Patent formalizes a cognitive principle — the static arc with indirect mobility — distinct in nature, function, and historical priority from any subsequent system. The volume documents the generality of this principle across three radically different technological domains: commercial avionics, consumer wearables, and military avionics.
Rodolfo Berretti (Sun,) studied this question.
