A processing apparatus includes a chuck table for holding a plate-like workpiece under suction. The servo sensors are configured to sense the transitions, and servo detection logic detects the relative timings of the laterally extending transitions sensed by the laterally displaced servo sensors as the magnetic tape is moved in the longitudinal direction. The logic interconnects are connected to the logic circuit and the metal capacitor plates are connected to the eDRAM cell. An inference engine analyzes the data in order to determine if the data corresponds to an actionable event relevant to the user. The cross beam is supported by die cut recesses in the upper edge of opposing side walls or by extensions extending from the sides of the cross beam. A logical client residing in a web server is extended with a proxy logical client residing in the thin client.
