  • Publication number: 20180058343
    Abstract: An internal combustion engine includes a cylinder block that defines a cylinder and a cylinder head mounted to the cylinder block. A reciprocating piston is arranged inside the cylinder for compressing an air and fuel mixture at a geometric compression ratio of at least 10:1. A crankshaft is arranged in the cylinder block and rotated by the piston. An intake valve is operatively connected to the cylinder head and controls delivery of air to the cylinder for combustion therein. A mechanism provides a constant peak lift of the intake valve over an angle of rotation of the crankshaft that is at least 5 degrees, i.e., an extended dwell at peak lift. A multi-stage boosting system having first and second gas compressors is selectively controlled to pressurize air that is received from the ambient for delivery to the cylinder. A vehicle having such an engine is also disclosed.

  • Patent number: 9778975
    Abstract: A method of isolating hidden data in a solid state memory system is disclosed including obtaining a logical block address (LBA) image from the memory system, obtaining a physical block address (PBA) image, determining whether an error exists in the PBA image and correcting the error, calculating an ETCRC on each sector of the LBA image and building a search tree indexed on the ETCRC value. For each sector in the PBA image, the method also includes computing an error tolerant cyclic redundancy check (ETCRC) value and searching for the ETCRC value in the LBA search tree. If the ETCRC value is found, also included is comparing the cyclic redundancy check (CRC) of the LBA and PBA sectors, and outputting to an output file the PBA sector as hidden data if either the ETCRC value is not found in the LBA search tree or the CRC comparison fails.
