An extracorporeal therapy machine removes blood from a patient in order to treat the blood and then return the blood to the patient. According to a preferred embodiment of the present invention, during operation of a multiprocessor data processing system, a service processor updates firmware in the multiprocessor data processing system from a first firmware setting to a second firmware setting. The method includes the addition of liquid carboxylic acids and a centrifugation step. The code position detector is provided with a code frame detector detecting a code frame which defines a fixed region of the 2-dimensional codes, and determining a dot of a target pixel as being a corner dot of the code frame. Optionally, an encapsulation film is formed on the silicon film after the GCIB process and the etching process or the annealing process. The proportions by weight of components and in the blend are in the range of about 30:70 to about 70:30 and the proportion by weight of component to the sum of components and is in the range of about 0.
