Method and apparatus are disclosed to allow non-wireless transmission or reception of data from one device to at least another device. In particular, the present invention presents p21-activated protein kinase PAK I, also known as protease activated protein kinase I which has been purified to apparent homogeneity. A coupler on the housing is automatically actuated upon the axial displacement of the cutting blade and the housing on the drive shaft. Accordingly, the head section of each even -numbered gripper is placed between the connection sections of two adjacent odd -numbered grippers. Some embodiments of the brace include provisions for accommodating horizontal movement of the rear impact guard. The compensator includes a means for phase-shifting and a means for exponentiation to generate a compensation signal such that the linearity error distortion signals are canceled in the system output while maintaining the desired fundamental signal.
