Methods and apparatus are provided for improving the accuracy and streamlining the process of preparing an imaged flexographic printing sleeve. The application agent may be associated with a 1-8YY toll-free number or other national or international telephone number. A second voltage follower of the amplifier amplifies without being saturated even if an input signal voltage approaches a ground potential when the input signal voltage is less than the bias voltage, but does not amplify when the input voltage is at least equal to the bias voltage. The electrode may be connected to a first conductive region of the electrode communication device and wherein upon movement by the patient or the conductive array, the electrode is connected to a second conductive region of the conductive array. The drive circuit controls the rotary motor so that the cover moves back and forth repeatedly in a substantially linear motion along the guide between a shutter closed position and a shutter open position over the imaging sensor array. An introducer straightens the distal portion for introduction into the patient.
