摘要:
An ignition and fuel control system 10 of a vehicle 18 is provided including a controller 22. The controller 22 is electrically coupled to an ignition system 14, a fuel system 16, a crankshaft position sensor 32, and a camshaft position sensor 34. The crankshaft position sensor 32 senses a crankshaft position and generates a crankshaft position signal. A camshaft position sensor 34 senses a camshaft position and generates a camshaft position signal. The controller 22 determines a crankshaft position and a camshaft position in response to the crankshaft position signal and the camshaft position signal respectively. The controller 22 identifies a reference engine cylinder in response to the crankshaft position and the camshaft position and generates a synchronization value. The controller 22 also enables the ignition system 14 and the fuel system 16 in response to the synchronization value.

A commercial frequency-modulated (FM) radio signal indoor localization system and method for finding a location of a mobile embedded device (such as a smartphone) within a building. Indoor localization is performed by receiving commercial FM radio signals on the device, analyzing the signals using signal quality metrics, and generating signal quality vectors for each signal and signal quality metric used for the signal. The signal quality metric can be any physical signal quality indicator. The signal quality vectors are added to obtain a current location fingerprint. The current location fingerprint is compared to fingerprints stored in a fingerprint database. The location associated with the stored fingerprint that is the closest match to the current fingerprint location is designated as the current location in the building of the mobile embedded device. Locally generated radio signals can be used in conjunction with the commercial FM radio signals to improve localization accuracy.

A composition for treatment of HSV-related pathologies including an expression vector for altering expression of a target sequence in an HSV-infected cell by production of single-stranded cDNA (ssDNA) in the cell in vivo suspended for topical application to an affected site in a suitable delivery vehicle. The expression vector is comprised of a cassette comprising a sequence of interest, an inverted tandem repeat, and a primer binding site 3′ to the inverted tandem repeat, and a reverse transcriptase/RNAse H coding gene, and is transfected into the infected cells for inhibition of HSV replication. The resulting ssDNA binds to the target sequence to alter expression of the target sequence for such purposes as gene activation or inactivation using duplex or triplex binding of nucleic acids, site-directed mutagenesis, interruption of cellular function by binding to specific cellular proteins, or interfering with RNA splicing functions.

Methods and compositions comprising a DNA expression cassette for producing ss-cDNA inside a host cell (in vivo). The expression system optionally contains a reverse transcriptase/RNAse H coding gene, and a restriction endonuclease gene. The cassette carries cloning sites in two distinct locations for cloning and expressing a sequence of interest. The mRNA then serves as a template for reverse transcriptase and synthesis of the ss-cDNA. In one embodiment, the ss-cDNA folds and forms a dsDNA “stem-loop” structure which can be designed to contain restriction endonuclease recognition site the stem portion for cutting off the ssDNA loop containing the SOI having minimal flanking sequence attached. In another embodiment, the mRNA template folds prior to reverse transcription and serves as a termination signal for the RT. Again, a ss-cDNA is formed having only minimal flanking sequence. The data shows the usefulness of this system for producing ss-DNA inside a host/target cell.
摘要:
A method and system for operating an internal combustion engine. The internal combustion engine is operable in a plurality of compression ratio operating modes. The method includes determining a relationship between a base engine threshold load where the high compression and low compression provide substantially the same engine fuel consumption and engine speed. The determined nominal relationship is modified by a factor, such factor being a function of a condition under which such engine is operating, to obtain a modified relationship. The modified relationship is a function of engine speed and the condition has an effect on knock generation in such engine. The modified relationship and engine speed are used in selecting one of the plurality of compression ratio operating modes for the engine. A hysteresis load as a function of engine speed is determined and applied to the determined hysteresis load to the modified relationship to inhibit switching oscillations between a pair of the plurality of compression ratio operating modes.

A method for producing ODNs in bacterial or fungal cells in vivo for treatment of sepsis so that, when the ODNs reach and knock down their target genes, and thereby kill bacterial or fungal cells or inhibit their growth, the bacterial or fungal accumulation in the bloodstream is held constant or diminished and the sepsis syndrome is reduced or eliminated. The invention also contemplates of certain ODNs for use in treatment of sepsis.
摘要:
A method for forming a via through a dielectric layer within a microelectronics fabrication. There is first provided a substrate employed within a microelectronics fabrication. There is then formed over the substrate a silicon oxide dielectric layer, where the silicon oxide dielectric layer is formed through use of a plasma enhanced chemical vapor deposition (PECVD) method employing tetra-ethyl-ortho-silicate (TEOS) as a silicon source material. There is then treated the silicon oxide dielectric layer with a plasma to form a plasma treated silicon oxide dielectric layer. Finally, there is then formed upon the plasma treated silicon oxide dielectric layer a patterned photoresist layer employed in defining the location of a via to be formed through the plasma treated silicon oxide dielectric layer. Through use of the method, the patterned photoresist layer is less susceptible to delamination from the plasma treated silicon oxide dielectric layer within an isotropic etch method employed in etching the plasma treated silicon oxide dielectric layer than is an otherwise equivalent patterned photoresist layer from an otherwise equivalent silicon oxide dielectric layer absent the plasma treatment.
