An electrical power system architecture uses an auxiliary power unit as an electrical power source during taxi and approach idle. The device comprises a microwave unit and a specimen positioning device which transports the specimen into a tank within the microwave unit where automated heating takes place. A microcontroller in the adapter receives the first and second calibration data and computes combined calibration data. Specifically it does not have to use the master-slave switch according to the Bluetooth specification. The first set of network element pairs include a number of pairs of the network elements. An object-unit resolution discriminator discriminates attributes of drawing objects in print data which is formed by a host, discriminates a kind of resolution processing of each drawing object, selects either one of a high resolution rasterizer and a normal resolution rasterizer every drawing object on the basis of the discrimination result, and switches a resolution processing.
