A system and method is provided for handling the collation of linguistic symbols of different languages that may have various types of compressions. The first contact pin includes a mating end, a body having a first body portion and a second body portion, a pair of ear portions and a pair of first blocking portions. The emitting unit and the receiving unit define a protected zone between them. A second gate, spaced apart from the first gate, overlies the N-well. During the forcible release of the object, the air around the absorption pad may be drawn into the pad holder, thus reducing or preventing the potential contamination by impurities of the object as well as the equipment around the object.
