The present invention relates generally to peptide molecules and to derivatives, homologues, analogues and mimetics thereof capable of inducing or facilitating analgesia or partial analgesia alone or in combination with other analgesic molecules. The cartridge includes a rear portion and a forward portion with a reduced diameter while the rear portion is dimensioned to fit into the breach of a rifle and defines a hollow chamber or interior volume for a mass of gun powder and primer. A V etching reaching down to a predetermined depth of the trench structure is subsequently performed in order to produce a V-profile. A serial to parallel data converter within the memory bank couples the parallel data from either half to the serial data path core. When the spool is in the opposite axial position, the spool can engage a feature on the housing that locks the spool from rotation while engaging electrical contacts mounted on the spool with stationary contacts mounted on the housing. The second device generates information related to precompensation based on the first signal.
