Abstract: A SAS expander collects data access information associated with a nexus and determines whether a data prefetch is appropriate. The SAS expander identifies potential data blocks utilizing previous data requests of the nexus. The SAS expander issues a data request to the target for the potential data blocks. The SAS expander stores the potential data blocks within a prefetch cache for future utilization within a data read.

Abstract: Methods and apparatuses for correcting an error in a data stream that is coded with a line code and an error detection scheme. Information relating to the line code is used to locate at least one possible error character. At least one possible correct character to replace one or more of the at least one possible error character is then identified. Subsequently, the error detection scheme is applied to the data stream updated with one of the at least one possible correct character. If none of the at least one possible correct character results in a valid data stream, an error that is observable by a user is generated.

Abstract: Driving multiple consecutive bits having a same logic value in a serial data stream involves driving a first bit of the multiple consecutive bits in the serial data stream at an initial voltage level, and driving at least two additional bits of the multiple consecutive bits in the serial data stream at voltage levels stepped down from the initial voltage level.

Abstract: The singlet delta energy levels of molecular oxygen (SDO) are generated to enhance the performance of internal-combustion engines, diesel engines in particular. In the preferred embodiments, this control takes place just prior to, and in the initial stages of, fuel injection. The SDO can be generated using different methods according to the invention, including thermal means, optical/laser energy, electrical/electromagnetic excitation, or a combination of these approaches. SDO may also be generated through reactions of a chemical fuel additive or a laser-excited chemical additive. A system for improving the performance of an internal combustion engine according to the invention includes a source or energy operative to generate singlet delta oxygen (SDO) from molecular oxygen, and apparatus for mixing the SDO with fuel prior to, or during, combustion. In the preferred embodiment, the SDO is delivered with air through an air-intake port, and a laser is used in a multi-pass absorption cell.
