A connector assembly includes a signal array with conductors including inner and outer conductive elements. With respect to elements to which a HIGH voltage is applied for a long time, a plurality of elements are connected in parallel, and at least some of the plurality of elements are driven by switching elements. The first current-collecting member, the core-body exposed portion, and the first receiving member are resistive-welded with the core-body exposed portion between the other members. Furthermore, the NIC operates to prevent placement of the data in a portion of the host memory where data has been previously placed by the NIC. By pre-acting wireless link synchronization establishment in handover before measuring stage, handover process time is reduced, system sources are saved, and handover reliability and quality are improved as well. In some embodiments, when processing source images, the source images may be downsampled during a portion of the processing to reduce computational overhead.
