Contextual vocabulary and methods of use are provided herein. A silicon-based wafer support tower is particularly useful for batch-mode thermal chemical vapor deposition and other high-temperature processes, especially reflow of silicate glass at above 1200\xb0 C. Various optical fiber devices may be achieved if the aforementioned optical fiber is used along with acoustic wave generating means and a mode dropper or a mode selective coupler. This method comprises determining real time need for access to the device and prioritizing access using a rate monotonic scheduling. A control is positioned on the resuscitation control system that can be operated by a rescuer to indicate that the patient is ready for application of a defibrillation shock, and the resuscitation control system pauses at least about a second, more preferably at least about two seconds, between operation of the control by the rescuer and application of a shock to the patient.
