Methods and apparatus for detecting a magnitude of a voltage at a face of a conducted electrical weapon (CEW). The magnitude of the voltage may be used to determine whether a pulse of a stimulus signal was delivered to a target. Structures for detecting the magnitude of the voltage may include structures that provide a stimulus voltage.

The invention belongs to a weapon namely to the automatic weapons without ammunition. Particularly it belongs to the weapons using the energy of the explosion mixture gas, flammable liquid or other mixture in the combustion chamber as a mover of bullets. A weapon without ammunition, arranged according to the bullpup scheme, contains: the barrel; the receiver in the form of a cylinder rolling in a rectangular box; the trigger mechanism; the piston for supplying combustible mixture to the combustion chamber and for cooking the compressed air in the mixing tube. This piston is connected by a rod with the piston gas tube; the cylinder full of compressed gas, flammable liquid or other mixture; the drum with several chambers of internal combustion in the form of elongated cylinders. When moving to the trunk a drum is pushed by the nozzle of the lower chamber in the rear part of the bullet and toilet it in the trunk from the top of the camera. This occurs by the rotation around its own axis and longitudinal movement along this axis; the ignition mechanism consisting of a piezoelectric element and the spark; the secondary ignition system consists of a battery and a capacitor; the venting mechanism with the gas tube and piston, in which the gases are directed toward the muzzle; the return mechanism; the multi-function ammunition cartridge of extended capacity, feeding the bullets into the machine vertically. There is a function of the butt, and when you transfer the spare magazines on the body of the soldier there is a function of armor plates.

Systems, devices, apparatus and methods for providing a semi-automatic rifle with ammunition magazine, having a docking port/station for allowing a semi-automatic pistol to be inserted. The trigger on the pistol can be used to fire the rifle and use the rifle ammunition. When the rifle ammunition is depleted, the pistol can be removed and separately fired using its' own ammunition.

A method of threat detection includes illuminating a scene with short-wavelength infrared (SWIR) illumination and receiving a return of the SWIR illumination reflected back from the scene. The method includes analyzing the return of the SWIR illumination to detect presence of man-made optics in the scene. Illuminating, receiving, and analyzing can be performed by a device, e.g., a rifle-mounted laser device.

A tactical device has a barrel having a first end, a second end, and a through hole that extends between the first end and a second end. A barrel housing has a first end, a second end and a through hole that extends between the first end and the second end. The barrel second end is configured to be inserted into the barrel housing first end and is axially moveable with respect to the barrel housing. A firing pin is mounted in the barrel housing through hole proximate the barrel housing second end and has a protrusion that extends toward the barrel housing first end. The tactical device has a safety means for maintaining the barrel in a first position in which the firing pin is spaced apart from the barrel second end.
