An apparatus to enable the flow of high speed gases through the apparatus, the apparatus including modifying a metal hose which can be a metal hose or a corrugated metal hose having an exterior braid and an interior liner. The reading device includes: a radiation source for emitting radiation which exposes a coded data portion on the interface surface; an image sensor for sensing the exposed coded data portion; a force sensor coupled to a nib of the reading device; and a processor for determining product identity data andor position data. In this way, a low-pressure region is created over the wafer and the wafer is suspended within the cooling station, without directly contacting any surface for support. A switcher activates the light emission elements in at least one of the element arrays while deactivating the others.
