Abstract:
An electromagnetically variable firing system for a firearm is disclosed which may include a trigger assembly or mechanism comprising an electromagnetically-operated control device which allows the user to select and adjust the trigger pull force-displacement profile electronically. In one embodiment, the control device may be an electromagnetic trigger mechanism comprising an electromagnetic snap actuator operated via a microcontroller. The microcontroller is configurable by a user to adjust the trigger force-displacement profile according to preset user preferences. The microcontroller energizes the actuator during a trigger pull according to a preprogrammed trigger force and/or displacement setpoint aided by a trigger sensor(s). The energized actuator creates a magnetic field which dynamically increases or decrease the trigger force required to fully actuate the trigger to discharge the firearm. In other embodiments, the control device may be an electromagnetic magnetorheological fluid actuator.

Claim (Index 1):
An electromagnetically variable trigger force firing system for a firearm, the firing system comprising:\n a frame; a striking member supported by the frame for movement between a rearward cocked position and forward firing position for discharging the firearm; an electromagnetic actuator trigger unit affixed to the frame and comprising:\n a stationary yoke comprising an electromagnet coil; \n a rotating member movable about a pivot axis relative to the stationary yoke and operable for releasing the striking member from the cocked position to the firing position; \n a trigger operably engaged with the rotating member, the trigger manually movable by a user from a first position to a second position which rotates the rotating member for discharging the firearm; and \n a permanent magnet generating a static magnetic field in the stationary yoke and rotating member, the static magnetic field creating a primary resistance force opposing movement of the trigger when pulled by the user; \n an electric power source operably coupled to the coil; the electromagnet coil when energized generating a user-adjustable secondary magnetic field interacting with the static magnetic field, the secondary magnetic field operating to change the primary resistance force dynamically during a trigger pull event initiated by the user.
