\u2018SPRolife\u2019 is a new and distinct variety of miniature rose plant, classified as a miniature climber. Non-flat portions are formed in both sides in a width direction of each of inner electrode layers. The method effectively allows selective orientation and reorientation of distinct ferromagnetic layers of a subset of the magnetoresistive elements on the substrate. Two private keys may be generated\u2014a first private key based on the at least one unique mobile identifier and a second private key based on the at least one unique vehicle telematics unit identifier. In another embodiment, mean MPI levels corresponding to respective transmitted intensity levels are generated and used to control slice levels of a slicer in order to compensate for MPI. The second carriage and the first carriage are releasably coupled to one another so the second carriage is moveable relative to the first carriage when the coupling of the first carriage and the second carriage is released.
