Methods and systems of providing power to a central processing unit provide for enhanced surge protection during CPU current consumption going from high current to low current consumption. Ultrasound matching layers or variable curvature geometries are employed at the tip aid in transferring the energy from the tip to the tissue. The generated output color values correspond to colors perceived by the human visual system for the same image as that captured by the image capture device. The absorbent assembly can include a fastening component disposed at an end region, the first fastening component adapted for refastenable engagement to the inner attachment member.
