A catheter securement device holds a medical article by securing an anchor member to an attachment region of a neonate. Methods for treating a hepatitis virus in a patient comprising administering an effective amount of the compound of formulas are also presented. The communication apparatus is further configured to convert sound waves, vibrations, solar energy, wind force and pressure force into electrical energy communicable to a battery cell. The actual path value is used for reading out a speed limiting value from a data table, which is stored in the automation system and which represents a stepped limiting value curve and for comparing the actual speed value with the read out speed limiting value. The control signal is enabled when one of the non-invertedinverting strobe signals is higher than the reference voltage and the other is lower than the reference voltage, and disabled when the non-invertinginverting strobe signals are the same logical level.
