A dampening device for an automated samplingdispensing device. The catalysts have a high open frontal area structure and composition advantageous for use in high particulate matter environments such as coal-fired industrial applications. The structure defines a pattern of radiation intensity. The scheduler maintains a plurality of QoS queues, which are then dequeued with a WFQ scheduler, which can be based on standard technology or a simplified low-cost implementation. The AMBA AHB allows the DSP to control the PLC operations without interference with high-speed data transfers.
