A reamer for use in minimally invasive hip replacement surgical approaches is provided. The organic insulator including the composition for preparing an organic insulator has increased charge mobility and an increased onoff current ratio, thus exhibiting improved properties, and the organic thin film transistor manifests uniform properties due to the absence of hysteresis. Embodiments of the invention use telephone identifying information such as the calling party’s number to identify, or create, user profiles for customization. The only AFM pinning layer employed is in the biasing layer structure so that when the magnetic spins of the AFM pinning layer are set the orientations of the magnetic moments of the AP pinned layer structure are not disturbed. The first data stream is transmitted to the receiver device when the phase of the first clock signal differs from the phase of the second clock signal by greater than the predetermined amount.
