Apparatus and methods of arranging ground pins and signal pins in a card connector includes arranging a signal pins and ground pins in a card connector into at least six columns divided between a primary side and a secondary side of the connector. The inventive arithmetic unit collectively processes an input data string, which has generally been processed bit by bit, by four bits at a time, whereby a CRC arithmetic operation can be speeded up. Each winding has a reduced diameter so that the windings collectively form a funnel having a conical shape and an inherent bias. In turn, the BTSs serving the two cells may receive these DSC transmissions and responsively switch from operating in a first mode to operating in a second mode in which both BTSs continue receiving the access terminal’s data. The cradle is fastened to a holder, and a gasket is provided between the cradle and the holder. The chemical mechanical planarization pad may include a first component including a water soluble composition and water insoluble composition exhibiting a solubility in water of less than that of the water soluble composition, wherein at least one of the water soluble and water insoluble compositions of the first component is formed of fibers.
