An access tower has two mutually spaced side parts extending from a base part to the top part; and inclined cross parts each extending from one side part to the other. The method continues by partitioning the streaming data into a first data stream and a second data stream. The selected metadata preference and the selected notification preference are transmitted to a hosting system. The wafer saw may also be used to simultaneously sever and electrically isolate conductive traces that extend over adjacent semiconductor devices from connective lines therefor. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.
