Patent number: 10746488Abstract: An intrinsically safe firearm may include a handle and a frame connected by a pivot pin. One or more latches of the firearm can temporarily fix the firearm in a stowed orientation or a deployed orientation. In the deployed orientation, a magazine of the firearm can be removed from the handle; a slide of the firearm can be removed from the frame; a magazine safety allows a firing pin to strike a primer of a round in the firearm; and a trigger of the firearm is accessible to discharge the round in the firearm. In the stowed orientation, the magazine is not removable from the handle; the slide is not removable from the frame; the magazine safety prevents the firing pin from striking the primer; and the trigger of the firearm is not accessible.Type: GrantFiled: August 1, 2019Date of Patent: August 18, 2020Inventor: Brent Ford Regan

Patent number: 10746495Abstract: An impulse launcher is provided with a motor to store rotational kinetic energy in a flywheel. The stored kinetic energy is released using a planetary gear transmission that links the flywheel to a drive shaft. The kinetic energy is released when the planetary gear carrier is decelerated using a brake. The planetary gear carrier deceleration forces rotational acceleration of the drive shaft and deceleration of the flywheel. The drive shaft turns a primary drive sprocket and a secondary drive sprocket which pulls a studded drive belt which in turn drives a projectile located between the studded belt and a guide. The planetary gear system and belt drive allow rapid transfer of energy from the flywheel to a projectile.Type: GrantFiled: August 28, 2019Date of Patent: August 18, 2020Inventor: Thomas J Gieseke
