An image processing device controls a local resource, retrieves data files from a network, generates partial images from data included in the data files, and displays an image by combining the plurality of partial images. The central policy server includes a central database storing configuration information for the remotely situated policy enforcers. The coolant gas then exits the de-superheater and flows into the evaporatively cooled condenser coil where the coolant is further cooled and condenses into a liquid before finishing the air conditioning circuit by consecutively moving through an optional coolant receiving chamber, a thermal expansion valve, an evaporator, and returning to the compressor. Magnetic bodies are mounted on opposite sides of the Hall element to concentrate the magnetic field through the Hall sensor. Subsequent communications with the SU during the period are conducted using the optimum communications link.
