A console with adjustable pivoting arms. A predetermined length of the detected portion of the audio track corresponding to the first content feature is extracted from the audio track. Workload control modifies workload and scheduling to reduce power transients and subsequent temperature deviations. The thin SiO2 or SixGeyOz interfacial layer is sufficiently thin and discontinuous to offer little resistance to gate current flow yet has sufficient O to effectively block upward Ge diffusion during heat treatment to thereby allow silicidation of the subsequently deposited layer of cobalt. The voice-activated hands-free camera holder system includes a voice-activation assembly and a manual controller unit enabling the user to manipulate the micro-camera such that both hands of the user remain free for use during the procedure while providing the user with an ideal vantage angle for observation. The first stimulating component and the second stimulating component are in a parallel relationship to each other, to be used as prescribed by a physician, therapist and persons having special expert professional knowledge in the field.
