Certain exemplary embodiments can provide a system, machine, device, manufacture, circuit, composition of matter, and/or user interface adapted for and/or resulting from, and/or a method and/or machine-readable medium storing machine-implementable instructions for, activities that can comprise and/or relate to, controlling the amount of energy delivered to a projectile from a source of compressed gas.

Systems, devices, and/or methods for launching a projectile

A tunable mass coupled to a body subjected to forced vibrations that reduces the vibration amplitudes of the body in the forced vibration frequency band. The mass includes a container having a plurality of cavities with grooves in the lower surfaces and notched side walls. Each cavity is filled with spherical elements which are restrained by the grooves and notches. The tunable mass is constructed to respond in a spring like manner so that vibration frequencies of the mass are tunable to provide counter vibrations in the forced vibration frequency band. Vibration frequency amplitude reduction is provided by vibrations of the mass that are in phase opposition to the vibrations of the body.
