An apparatus and method for a dry disconnect coupling. A differential voltage that appears between the piezoelectric head and the first resistor and between the capacitor and the second resistor is amplified, so that the acoustic-system admittance of the piezoelectric head can be detected with a high SN ratio. The PAT information includes alias and location information necessary to locate a desired path for the alias. The adjustable end is adjusted via a spring-loaded button that is located on the broom, and which can lock upon one of a plurality of holes located on the respective adjustable end. In certain embodiments, the Na+\u2014K+-2Cl\u2212 co-transporter is NKCC1.
