A level shifter is disclosed and includes at least four Type 1 transistors and at least four Type 2 transistors. One example of a method is performed in connection with a laser of an optoelectronic transceiver. Additionally, the implant may be \u201cmatched\u201d to provide the implant with similar physical andor chemical properties as the host tissue. Provided on the label is a connector-connection indication which indicates an orientation of the battery-side connector to be connected along with a battery-housing indication which indicates a shape and a housing orientation of the battery to be housed in the housing part. Rotation of the cam around an axis perpendicular to the main axis provides angular displacement of the distal end assembly relative to the main axis. At least one plate is secured within the body tip pocket and has inboard and outboard surfaces.
