The present invention relates to thermal printing or thermography, more specifically to the generation of a mathematical model of the thermal steady state printing characteristics of a thermal printing system, and the use of such model for the driving of a thermal print head. A shaft is rotatably retained by the housing, and a rotor has a hole and keyway for producing a nonferrous hole through the shaft. In either case, the handle is always moved in the same direction that the operator wants the boat to travel. The method further comprises for at least one resource of search results, determining, using the one or more processors, a size of a data transfer required to access the one resource. The fixing member is a detachable member which fixes the other end of the cylindrical body onto the projection. The input device includes a plurality of sensor electrodes for capacitive sensing disposed in a first layer and within a sensor electrode region comprising an areal extent of the plurality of sensor electrodes.
