US12618634 - Muzzle flash simulator and method for generating light trail

The patent describes a muzzle flame simulator designed for toy air guns, which generates a light trail through a combination of a projectile sensor, a controller, and multiple illuminating components that emit light of varying colors and intensities. The system activates upon detecting a projectile, utilizing preset control signals to create a realistic visual effect that simulates a muzzle flash.
