  • Firearm orientation and drop sensor system
    Patent number: 7188444
    Abstract: A sensor system for detecting jarring, acceleration or other application of force to a firearm, and/or movement of the firearm into an undesired orientation, which includes a sensor array mounted to a firearm. The sensor array detects the excessive acceleration and/or movement of the firearm into certain orientations and generates a sensor signal indicative of a fault condition. In response, a control system blocks or interrupts the firing sequence of the firearm to prevent inadvertent discharge of a round of ammunition by the firearm.

  • Roller sear/hammer interface for firearms
    Patent number: 7181880
    Abstract: A roller sear/hammer interface for a firearm. The sear has a roller rotatably mounted between two side plates forming a portion of the sear body. As the trigger is moved, a linkage connecting the trigger and sear causes the sear to pivot rearward such that the roller engages a notched surface formed in the hammer. This rolling action releases the hammer to strike a firing pin to fire a round of ammunition. When the trigger is released, the sear roller rolls downward into an engaged and locked position within the notch formed in the hammer.
