The disclosed embodiments relate to a method and system for regeneration of a catalyst. The system includes a multiaxially movable arm, a fiber optic cable, a laser source, a focusing head, a focus lens, and a shield. A pedestal portion is formed on the base plate, and a channel to cool down electronic parts such as a diode is formed inside the pedestal portion. Timing alignment and power level control among each of many field units and the base station is achieved by analyzing coded transmissions received at the base station in a corresponding time slot as transmitted by each field unit. This series of processing allows access to an address in the memory array specified by a count on an address counter.
