An aspect of the invention relates to a garment which comprises at least a first zone and a second zone. In an embodiment, a system includes a first lead configured to be coupled to a tip wire and a second lead and the second lead to a ring wire. A second branch of another frequency converter is adapted for and operable at a second switching frequency of more than 5 kHz for outputting a supplementary alternating current generated at said switching frequency to the same winding. Both the fixed arm and the movable arm are designed to have clamping teeth on the curved inner edges to clamp large size cylindrical work pieces and the floating pads are for smaller size cylindrical work pieces and work pieces of different shape and sizes. Once the gauge is properly adjusted to the patient and locked into place, the user reads a measuring device on the gauge, which indicates the relative positions of the components of the adjusted gauge. In a more specific embodiment, the third mechanism includes a reflective backstop that is selectively positioned behind the second mechanism to reflect back-radiated energy forward of the second mechanism, thereby causing reflected electromagnetic energy to combine in phase with forward-radiated energy from the second mechanism.
