A wireless communication device is provided. The method includes obtaining a base context identifier, searching for a patch in a context corresponding to the base context identifier, obtaining a system description, corresponding to a system where the system description includes more than hardware version and operating system version information, and filtering patches found in the search to remove patches not applicable to the system. By such composition of the optical pickup, amplitude deterioration of the tracking error signal accompanying displacement of the object lens is reduced. The use of the compensating element equalizes signal amplitudes and minimizes phase errors of signals in an interested frequency range and diminishes the amplitudes of high frequency signals which exhibit high degrees of phase error. A continuous supply of paint is achieved by means of two parallel conveying lines 2 and 2, through which quantities of paint 21 and 21 are conveyed with an offset from each other and are discharged in a metered manner. The present invention also discloses methods of making the compounds, compositions containing the compounds, and methods of treatment using the compounds.
