An audio coding device that optimizes quantization parameters for fast convergence of iterations. The PWM module controls switching of an inverter that powers a motor. The optical film set is disposed on the back plate. A first process of the pair of processes is allocated from a first node in the multi-node system to a second node in the multi-node system that hoses a second process of the pair of processes. The submunition may also comprise an elongated pendulum having a hollow core sized to receive said elongated delay member, the elongated pendulum adapted to be movable between a locked position that mitigates likelihood of inadvertent detonation of the explosive payload and an unlocked position that enables detonation of the explosive payload. The air passage as well as the wear of this spring-loaded brake can be monitored reliably and in a simple manner by means of a measuring device which continuously monitors the change in the relative position of the housing parts.
