A force isolating apparatus for use in a vehicle seat suspension, where the suspension has a base frame and an upper frame mounted to move horizontally relative to the base frame. A drillable bridge plug comprising a mandrel and at least one slip assembly at least partially made of a material having less than 10% elongation. The second correcting step relies upon a greater number of normal pixels than the first correcting step to correct the defective pixels in a higher precision than the first correcting step. The driver circuit has a power factor control circuit that includes a tracking circuit configured to produce a tracking signal indicative of the voltage of the supply line. Cradles having sleeves which mate to the expander bar assembly facilitate user tailored mountings. A mechanical splicing method including inserting a field fiber into a splice connector such that an end of the field fiber contacts an end of the stub fiber within an alignment mechanism of the splice connector, and applying axial force to the field fiber so as to cause the stub fiber to buckle within a cavity defined by the splice connector.
