  • Publication number: 20080173081
    Abstract: A rough road detection system includes an engine speed module, a feature space module, a normalization module, and a rough road module. The engine speed module generates an engine speed signal based on a crank signal. The feature space module generates a feature space signal based on the engine speed signal. The normalization module generates a normalized signal. The normalized signal is based on the feature space signal and a normalization value that varies in accordance with the engine speed signal. The rough road module determines whether a rough road condition exists based on the normalized signal.

  • Publication number: 20070181871
    Abstract: The present invention provides a low-voltage organic thin film transistor having a gate dielectric layer of ultra-thin metal oxide self-grown on a metal gate electrode by O2 plasma process. The metal gate electrode is deposited on a plastic or glass substrate. By directly oxidizing the gate electrode by using O2 plasma process, the gate dielectric layer of metal oxide is formed with a thickness of several nanometers on the gate electrode. The organic semiconductor layer is deposited on the gate dielectric layer, and source/drain electrodes are formed on the organic semiconductor layer. Before the organic semiconductor layer is formed, an organic molecular monolayer may be formed on the gate dielectric layer by using molecular self-assembly technique. The gate dielectric layer may be formed at room temperature to about 100° C.

  • Patent number: 7221924
    Abstract: A notch filter with a high Q factor, which is integrated with a first and a second cascoded LNA, is totally contained on an integrated chip. The notch filter, comprising two Q-enhancement circuits, is coupled to the second differential LNA. The two Q-enhancement circuits are combined to generate sufficient negative impedance to compensate for the loss in the on-chip low Q inductors. To improve the image rejection of the notch filter in a wide frequency band, the notch filter uses an automatic current tuning circuit which consists of an analog multiplier and fixed and voltage controlled current sources. Furthermore, by modifying the connection and location of the tunable varactor, another wideband tunable notch filter is implemented. The notch filter can be applied in all current wireless receiver systems.

  • Publication number: 20070088591
    Abstract: An alarm system (10) includes a plan management module (100), a production management module (200) and an alarm management module (300). The plan management module receives a customer order and sets planned delivery data according to the customer order. The production management module downloads production data. The alarm management module determines whether the production data conform to the planned delivery data and generates an alarm if the production data do not conform to the planned delivery data. A related method for production schedule control is also provided.

  • Publication number: 20070040632
    Abstract: A cancellation circuit to remove the anti-resonance signal from a resonator. Micro-mechanical and surface and bulk acoustic wave resonators include an anti-resonance in an output signal. This has an undesirable effect on certain types of systems in their function and performance. An anti-resonance cancellation circuit removes the anti-resonance from the output of the resonators by providing a signal which is subtracted from the output of the resonator. The cancellation circuit includes a capacitor which is matched to the static capacitance of the resonator. The loads of the resonator and cancellation network are also matched.

  • Patent number: 7052897
    Abstract: Methods and compositions are provided for altering the DNA recognition and cleavage characteristics of an endonuclease without prior knowledge of the endonuclease's three-dimensional structure and/or amino acid residues responsible for activity and/or specificity. Methods include subjecting a mutagenized endonuclease gene library to a genetic selection in prokaryotic cells which tolerate the expression of mutated endonuclease and where the endonuclease is active and determining the altered recognition-site specificity for the endonuclease.

  • Publication number: 20050158834
    Abstract: Methods are provided for engineering novel strand-specific nicking endonucleases by means of an in vivo enrichment of a plasmid library containing a randomly mutagenized restriction endonuclease gene. The plasmids contain adjacent to the gene a cleavable or nickable sequence for cleaving or nicking by the endonuclease product of the gene and a second recognition site for a second endonuclease. The plasmid library is used to transform unmodified host cells. Plasmids from the cultured transformed cells may be analyzed by an in vitro assay for nicking and the nicked plasmids pooled and used to transform host cells. The product is then pooled and the single-stranded specificity of the endonuclease is then determined. The product is either cloned after amplification or identified by use of a selectable marker.
