    Abstract: In a dual-gradient drilling apparatus, a subsea solids processing unit includes a housing, a solids processing mechanism disposed in the housing between a drilling mud inlet and a drilling mud outlet, and a flushing mechanism configured to flush the solids processing mechanism with a flushing fluid. A subsea solids processing unit may be controlled by rotating the solids processing mechanism in a forward direction and increasing a drive torque when a measured speed of the solids processing mechanism is below a desired rotation speed. The desired rotation speed may be decreased when a measured torque exceeds a selected maximum and a rotation direction of the solids processing mechanism may be reversed when the measured speed falls below a selected minimum.

    Abstract: Systems and methods for accumulating data relating to the performance of one or more components of a read channel are described. In one aspect, a programmable channel quality monitor is operable to accumulate performance data corresponding to a recorded test data sequence spanning two or more data sectors of the magnetic medium. The channel quality monitor preferably is incorporated in a disk drive system. A method of accumulating performance data from a read channel also is described. In accordance with this inventive method, an original test data pattern is written to multiple data sectors of the magnetic medium. The original test pattern is read from the multiple data sectors of the magnetic medium to produce a readback test pattern. In this method, performance data relating to a comparison of the original test pattern and the readback test pattern is accumulated.
