A computer implemented method, data processing system, and computer usable program code are provided for detecting printer conditions. For some embodiments, the CAM device is continuously sampled to generate sampling signals indicating the number of active states and number of compare operations performed during each sampling period. The locking guide is formed by pressing a plate member having a predetermined thickness. However, the lock restores when the terminal fitting is inserted completely, and locks the terminal fitting in the cavity. Local changes may be, for example, local reduction in RMS of high frequency components, for example, during a stress test. Methods and devices are provided by which a device or apparatus can generate a sterilizing plasma such that a stethoscope, or portion of a stethoscope, can be placed within or near the device or apparatus so that the plasma disinfects andor sterilizes andor decontaminates at least a portion of the stethoscope.
