The invention relates to the field of wireless communications, more particularly to a method of and device for switching between antennae in communication with a diversity receiver, each of the antennae receiving signals transmitted from a single source. More specifically, the invention relates to a system for associating particular calibration information with a particular radiographic image. The apparatus further includes a movable back gage assembly that works in combination with the joggle die system to allow an operator to accurately position the workpiece between the joggle dies at a preselected position. Then, a plurality of N-type semiconductor materials and a plurality of P-type semiconductor materials alternatively arranged on the electrodes are formed. The article has an upper particle free polymer material having a toe region and an ankle region. The herein probes may be very useful in systems and methods that benefit from probes having resolution capabilities less than the dimensions of the objects to be analyzed.
