This research aims to compare the Berretti Patent microbiological diagnostic device with three modern technological systems using arc indicators.
Conducted comparative analyses of the Berretti Patent and Boeing 767 EICAS, Apple Watch Activity Rings, and F-35 HMDS.
Examined the cognitive principles of the static arc with indirect mobility across different technologies.
Analyzed historical priorities related to the development of each device.
Demonstrated that the Berretti Patent introduced a unique cognitive principle not replicated in later systems.
Confirmed that arc indicators function differently in commercial avionics, consumer wearables, and military avionics.
Highlighted the historical significance of the Berretti Patent's design over subsequent technological developments.

Abstract

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.
