An apparatus for selecting random length boards for nesting into a single row of predetermined lengths includes an accumulating conveyor with longitudinal tracks positioned adjacent a storage rack with the longitudinal channels aligned with the tracks. Variations in current, from high to low and from positive to negative, are timed to coordinate with the thermal time constant of the conductor or cable. The elongated handle has an open end. Once affixed, the RFID device remains an integral part of the wristband. The location determination logic determines a revised estimated location based on the measured signal strengths and the revised transmit power for the wireless device.
