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 24):
An electromagnetic firing system for a firearm, the firing system comprising:\n a frame; a striking member supported by the frame and movable between a rearward cocked position and forward firing position for discharging the firearm; a pivotable sear configured to selectively hold the striking member in the cocked position; an electromagnetic actuator trigger mechanism supported by the frame, the trigger mechanism configured to create a dual loop magnetic flux circuit and comprising:\n a stationary yoke comprising an electromagnet coil operably coupled to an electric power source, the coil having an energized state and a de-energized state; \n a rotating member pivotably coupled to the stationary yoke about a pivot axis, the rotating member movable between an unactuated position engaging with the sear and an actuated position disengaging the sear; \n a trigger operably engaged with the rotating member and manually movable by a user for applying an actual trigger force on the rotating member; and \n a permanent magnet generating a static magnetic flux holding the rotating member in the unactuated position, the permanent magnet generating a static magnetic flux creating a primary resistance force opposing movement of the trigger when pulled by the user; \n a programmable microcontroller operably coupled to the power source and communicably coupled to a trigger sensor configured to sense the applied trigger force, the microcontroller when detecting the applied trigger force being configured to transmit an electric pulse to the electromagnet coil of the trigger mechanism; the electromagnet coil when energized generating a secondary magnetic flux interacting with the static magnetic field, the secondary magnetic field being configurable by the user via the microcontroller to increase or decrease the primary resistance force when the trigger is pulled by the user.
