Abstract: Smart membranes are integrated into a small, unmanned surface vessel to enable the efficient, automated cleanup of oil spills. Such a vessel has the potential to provide a low-cost, modular solution for day-to-day oil-spill cleanup operations, especially in confined aquatic areas (e.g., under piers or in the small spaces between marine vessels and piers). The membranes are provided on the surface of a conveyor belt that circulates the membranes through the surrounding body of water for oil collection, as well as through an internal reduction chamber of the vessel for oil release. The smart membranes are adapted to attract and repel oil in response to low-voltage commands applied across the conveyor belt, using a process that is repeatable for a number of cycles, offering high efficiency and long durability. Segments of the conveyor belt can be electrically isolated from one another to allow disparate electrical potentials to be imposed thereon.

Abstract: A command to read specific data stored at a memory die is received. A read operation is performed while operating both a memory controller and the memory die simultaneously at a first frequency. A processor determines whether a first error rate associated with the memory die satisfies a first error threshold criterion (e.g., UECC). Responsive to determining that the first error rate satisfies the first error threshold criterion, the read operation is repeated while operating at least one of the memory controller or the memory die at a second frequency that is different from the first frequency. The processor determines whether a second error rate associated with the memory die satisfies a second error threshold criterion. Responsive to determining that the second error rate satisfies the second error threshold criterion (e.g. UECC persists), determining that the read operation has failed.
