Abstract: Transmit equalization over high speed digital communication paths may be compensated in a receiver for a probe on that path. In one example, a probe input provides a signal from an electronic communications path, the signal having been processed by a transmit equalizer. A filter circuit processes the signal to compensate for the transmit equalizer, and a decoder decodes the processed signal and produces an output for use by test equipment.

Abstract: A method is provided, which includes operating a two-stroke engine with a lubricating fuel, the lubricating fuel including at least one fuel selected from the group including C1-6 alcohol, gasoline, ether, ketone, nitromethane, and a mixture thereof, and at least one lubricant selected from the group including biodiesel, lipid, fatty acid alkyl ester, fatty acid, and a mixture thereof. Lubricating fuel compositions are also provided.

Abstract: A method and apparatus to improve modulation efficiency for chip to chip interconnects. Modulation objects that are integer multiples of a fundamental time unit (FTU) are used to populate a symbol period that is also an integer multiple of the FTU. A possible symbol set is established as the set in which the modulation object occupies every possible combination of slots within the symbol period. By permitting the modulation object to overlap positions in different symbols of the set, greater modulation efficiency is achieved.

Abstract: At least two sequences of predetermined reference times are established on respective ones of at least two communication lines. At least some of the reference times of at least one of the sequences occur out-of-phase with at least some of the reference times of another of the sequences. Digital data is encoded onto data signals on one or more communication lines such that a time difference between at least one of the data signals and the nearest one of the reference times on one of the communication lines is smaller than the time difference between the same data signal and the nearest one of the reference times on another one of the communication lines.
