Based on a difference image of three temporally consecutive frame images, a moving object region where a moving object is displayed and a background region are extracted from a central frame image. A dielectric resonator is also provided which includes a resonator main body formed from the composition. The compensating network is arranged for counteracting coupling between the antenna radiating elements. The cable carrier is dimensioned to contain at least one cable extending through the support arm, a first end fixed relative to the support arm and a second end extending towards the hub. The patterned dry film layer is used as an electroplating mask to electroplate a circuit layer on the portion of the seed layer exposed by the patterned dry film layer.
