The invention relates to an aiming method, aiming system and computer program product utilized in the aiming method where also a real-time bullet velocity of a fired shot by a sniper rifle is utilized. The bullet velocity is measured in a suppressor in real-time for each fired shot. The suppressor sends the measured bullet velocity to a data logger of the sniper rifle. The data logger updates a bullet trajectory to a target after each fired shot and on the bases of an updated bullet trajectory the data logger sends new reticle setting to an optical scope connected to the sniper rifle.

The invention relates to a device for determining a motion characteristic of a projectile ejected from a toy gun. The device comprises a body defining a channel for receiving a moving projectile from the toy gun; a detecting unit configured to detect motion of the projectile in the channel; and a processing module configured to generate data defining a motion characteristic of the moving projectile based on the detected motion of the projectile in the channel. The invention also relates to a device assembly having the described device, and a support releasably connectable with and provides support to the device. The support is movable between an extended configuration and a retracted configuration. When in the extended configuration, the support is adapted to stand freely on a surface to support the connected device; and when in the retracted configuration, provides a handle to allow the device to be held.

A waveguide arrangement for measuring the speed of a projectile during passage through a weapon barrel arrangement includes a main waveguide and at least one auxiliary waveguide. The main waveguide has a cross-section suitable for the passage of the projectile. The auxiliary waveguide extends adjacent to the main waveguide and is connected to the main waveguide via an opening. An isolator is arranged in the auxiliary waveguide. The waveguide arrangement is particularly suited for large-caliber ordinance and has at least one coupler extending at least partially in the isolator. The speed of the projectile in the main waveguide is measured at a frequency below the limiting frequency. The transmitting coupler is arranged at a spacing distance from the muzzle in order to prevent an exit of the generated signal from the weapon barrel arrangement.

An electric-field sensor is provided that includes a voltage-controlled capacitor and generator circuitry. The voltage-controlled capacitor is influenceable by an electric field created by a target located a distance from the solid-state electric-field sensor. The generator circuitry is configured to generate a modulated voltage for driving the voltage-controlled capacitor to produce a modulated capacitance as the voltage-controlled capacitor is influenced by the electric field to enable measurement of the electric field. In this regard, the voltage-controlled capacitor and generator circuitry are configured such that, in operation, an electric field of the target causes a change in the modulated capacitance and a current flow through the voltage-controlled capacitor. An electric potential of the target, then, is measurable as a function of the change in magnitude of the current flow through the voltage-controlled capacitor.

A muzzle-mounted chronograph for measuring velocities of projectiles launched from firearms. The chronograph includes a sensor module and a controller. The sensor module includes a first and second coils and a device for applying a stable magnetic field to the first and second coils. The controller determines a velocity of a projectile passing by the first and second coils based on detected variations in magnetic fields at the first and second coils.
