An IP router is integrated with an LRTR. Independently, the pointer is defined to point to a second feature. A filter is arranged to filter the intermediate frequency signal. Further, the attaching member and a back portion of the front layer define a spine structure that extends to the tips of the mirror. The spacing between the blow head and the mold is defined by a Pressure Profile which is responsive to the sensed pressure within the mold. In the apparatus, a substrate pre-heater pre-heats the substrate.
