A module for an electrical distribution system is provided. A tilt meter adapted to measurably detect a tilt of the support bearing is coupled to the support bearing, where the tilt is defined as an angular difference in bearing orientation between a first bearing position and a second subsequent bearing position that is cause by an axial thrust on the rotary body. A card-holder unit has first and second card-holding compartments lying in horizontal planes that are vertically spaced. A method for manufacturing an external fluid-filled catheter pressure transducer describes connecting sections of tubing to an inverted sensor module, and providing a reference port for the inverted sensor module. At the same time, the low input impedance of the common-basegate PA reduces the voltage swing at the transmitter output and prevents the transmitter output from being compressed or modulated. The number of entries available in the SWQ are monitored by the ULP so that it does not overwrite any valid entries.
