Disclosed is a method for transmitting data from an RLC layer in a radio communication system. The control section compares a line width of the registration mark with a predetermined reference value of the line width to discriminate between abnormality and normality. Data flow separation module, features extraction module, classification arbitration module and protocol features library module are included. The biometric data can be of any type. The pivot includes a pair of rotational joints which are spaced apart to allow the diaphragm to pass therebetween as the lever pivots about the pivot axis. An advantageous property of the present invention is its versatility; the system may be quickly and easily adapted to synthesize an attenuated version of any RNA virus.
