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 16):
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; an electromagnetically adjustable trigger mechanism operably coupled to the striking member for discharging the firearm, the trigger mechanism comprising an electromagnetic actuator including:\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 for movement between an unactuated and actuated positions, the rotating member operably coupled to the striking member for moving the striking member from the cocked position to the firing position; \n a trigger movably coupled to the stationary yoke and interacting with the rotating member, the trigger manually movable by a user from a first actuation position to a second actuation position which rotates the rotating member for discharging the firearm; and \n a permanent magnet generating a static magnetic flux in the yoke and rotating member, the 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 electromagnetic actuator of the trigger mechanism and pre-programmed with a trigger force setpoint, the microcontroller configured to:\n receive an actual trigger force applied to the trigger by a user and measured by a trigger sensor communicably coupled to the microcontroller; \n compare the actual trigger force to the preprogrammed trigger force setpoint; and \n selectively energize the electromagnetic actuator based on the comparison of the actual trigger force to the trigger force setpoint; \n wherein the electromagnet coil when energized generates a user-adjustable secondary magnetic flux interacting with the static magnetic field, the secondary magnetic field operating to increase or decrease the primary resistance force when the trigger is pulled by the user.
