  • System and method for weapon discharge inhibition
    Patent number: 8381426
    Abstract: A firing inhibition system for a firearm includes an electromechanical actuator electrically connected to a dynamic grip recognition module including at least one sensor and a microcontroller, wherein the at least one sensor is located in a portion of a firearm operable to receive grip pressure from a user and wherein the at least one sensor is operable to transmit a signal to the microcontroller, wherein the microcontroller is operable to receive programming comprising grip pressure of an authorized user and is operable to interpret whether the grip pressure of the user matches the grip pressure of the authorized user, and to send a signal to the electromechanical actuator to actuate or to not actuate.
