An attempt to counter successful attacks through Starfleet shielding by the Borg and other races, auto-modulating shields are designed to immediately adapt to the characteristics of incoming fire. The system relies on advanced computational algorithms spread across the entire shield generator network. Working together, generators can monitor and analyze the smallest of variances across the entire grid and, using this information, hypothesize the correct new frequency modulation to tune the shields to. The process takes approximately 0.3 microseconds.
