A circuit device and method for designing a serial link receiver, which accommodates a wide input voltage range and provides tolerance to high termination voltages. A spin plate extends substantially across the separation chamber adjacent to the lower end thereof. A dummy memory cell circuit is operative to draw current from the source line responsive to the n bit data word such that a total current drawn by the memory cell array and the dummy memory cell circuit during a program operation is given by n* a current drawn by one of the n memory cells. The fibrous streams are charged along all or at least a portion of their route from the point of discharge to the surface of the collector. The retainer ring has a spherical outer surface which forms a ball joint with a spherical socket cavity within the head to enable the head to be angled relative to the shank. At least a portion of the electrical power capacity of the electric generation unit may power a water purification unit such as a vapor compression distillation unit, and heat output of the electric generation unit may supply heat to the water purification unit.
