An electronic locking system is operable to prevent a firearm from firing. The firearm includes an operating mechanism. The electronic locking system includes a power source configured to store electrical energy used to operate the electronic locking system; and a power generation element configured to generate electrical energy as a result of an operation of the operating mechanism, wherein at least a portion of the electrical energy generated by the power generation element is received by the power source.

An apparatus, device, or method may detect or track aim direction or motion of a firearm and display information indicative of such aim direction or motion. Sequence of bullet strikes on a real or virtual target by multiple gunshots may be determined. A method may comprise detecting one or more gunshots of the firearm discharging live ammunition, measuring or determining aim directions or motions of the firearm before, during, and/or after the one or more gunshots, recording these measurements or determinations, and generating output for displaying images on a display.

The projectile-launcher operation monitoring device includes at least one displacement-sensor and a processor coupled with the displacement-sensor. The displacement-sensor acquires measurements relating to the displacement of the projectile-launcher and to produce a sampled time signal of values relating to the displacement. The processor receives from the displacement-sensor the sampled time signal to determine projectile-launcher operation parameters therefrom, by employing a deep-learning system. The deep-learning system includes an encoder receiving sample-frames from the sampled time signal producing codes relating to the sample-frames. Each of the codes is a vector of values relating to the probabilities of features in the received sample-frames.

Various types of structures, along with associated systems, are disclosed herein and configured for responding to an energy wave for changing a state of a mechanism to which said structures are operatively coupled. In at least one embodiment, the structure provides a material selectively changeable upon exposure to the energy wave to cause at least a portion of the material to mechanically degrade from a first state to a second state. When the material is in the first state, the material forms a mechanical or electrical link with the mechanism such that a force or an electrical current can be transmitted through the structure. When the material is in the second state, degradation of at least the portion of the material disrupts the mechanical or electrical link and inhibits transmission of the force or electrical current through the structure.

A weapons system is comprised of a human transported weapons subsystem, and a drone weapons subsystem. The human transported weapons subsystem is comprised of a targeting subsystem providing for selection of a selected target, a computational subsystem, and a communications subsystem. The drone weapons subsystem has munitions with positioning and firing capability thereupon, and has communications with the human transported weapons subsystem. The targeting subsystem utilizes communications with the drone weapons subsystem; and, the computational subsystem determines where the drone weapons subsystem is and where the selected target is and where the drone weapons subsystem needs to be located in order for the drone weapons subsystem to aim the munitions to strike the selected target. The human transported weapons subsystem communicates to the drone weapons subsystem to provide information on aim of the munitions from the drone weapons subsystem and communicates to provide activating positioning of the drone weapons subsystem and firing of the munitions from the drone weapons subsystem, responsive to the computational subsystem. The drone weapons subsystem, responsive to communications from the human transported weapons subsystem, fires the munitions from the drone weapons subsystem aimed at the selected target.

A military vessel may include a directable weapon and an antenna. The antenna can be swiveled from a first position, in which the antenna is disposed essentially vertically, into a second position, in which a height of the antenna above the military vessel is reduced to increase a directing range of the directable weapon compared to the first position. A method for operating a military vessel with a directable weapon and an antenna may involve swiveling the antenna from a first position, in which the antenna is disposed essentially vertically, into a second position, in which the height of the antenna above the vessel is reduced to increase the directing range of the weapon compared to the first position.
