Abstract: A conditioning mechanism is placed forwardly of the cotton harvesting mechanism on a cotton harvester. Opposing elements compress portions of the cotton plant to compress the cotton bolls and deform the cotton boll hulls. The deformation loosens the cotton fiber relative to the hulls to improve the ability of the harvesting mechanism to harvest the seed and fiber. In one embodiment, differential surface velocity of the opposing elements improves boll opening and fiber orientation for more effective spindle contact.

Abstract: An apparatus and method provides the capability of mirroring storage from a primary system to a mirrored system in a way that uses parallelism in the mirrored system to maximize the efficiency of writing data to the mirrored storage for operations that do not conflict while serializing operations that do conflict. The mirroring of the present invention is “logical mirroring”, which does not require identical disk drives, and which supports mirroring between geographically remote locations to protect against catastrophic site failure. Parallelism is achieved in the mirrored system by dividing the virtual address space into multiple ranges, and by assigning a group of tasks to each range. When an operation is received on the mirrored system, the virtual address range that the operation affects is determined, and the operation is then delegated to the task group that corresponds to the affected virtual address range. By dividing the virtual address space into ranges, tasks in different ranges (i.e.
