A video game processing apparatus for controlling progress of a video game is provided. The instrument includes an activation member that is operable to selectively activate the blade and a controller that is operable to select the energy level at which the blade will be activated. In a second clock frequency multiplier, a flexible-injection-rate injection-locked oscillator locks to super-harmonic, sub-harmonic or at-frequency injection pulses, seamlessly transitioning between the different injection pulse rates to enable a broad input frequency range. The feature extractor receives an audio signal and extracts recognition features. The element is preferably formed by compressing an amount of loose particles of one or several solid combustible materials, such as among others wood waste and sawdust, without adding any binding agent.
