  • Patent number: 8825481
    Abstract: Techniques are described for training a speech recognition model for accented speech. A subword parse table is employed that models mispronunciations at multiple subword levels, such as the syllable, position-specific cluster, and/or phone levels. Mispronunciation probability data is then generated at each level based on inputted training data, such as phone-level annotated transcripts of accented speech. Data from different levels of the subword parse table may then be combined to determine the accented speech model. Mispronunciation probability data at each subword level is based at least in part on context at that level. In some embodiments, phone-level annotated transcripts are generated using a semi-supervised method.

  • Patent number: 8766013
    Abstract: The invention relates to a process for the production of hexahydro-iso-alpha-acids starting from iso-alpha-acids (or tetrahydro-iso-alpha-acids) in which iso-alpha-acids (or tetrahydro-iso-alpha-acids) are mixed with a heterogeneous ruthenium containing catalyst, that catalyzes the hydrogenation from iso-alpha-acids or tetrahydro-iso-alpha-acids to hexahydro-iso-alpha-acids, either in solvent-free conditions, or in the presence of a solvent phase (e.g. carbon dioxide, water, ethanol or another organic solvent, or mixtures thereof), and in the absence or presence of other hop compounds (such as beta-acids).

  • Patent number: 8710273
    Abstract: The invention relates to a process for the production of iso-alpha-acids starting from hop alpha-acids in which an hop alpha-acid containing feed is contacted with a heterogeneous alkaline earth metal based catalyst, that essentially does not dissolve in the alpha-acid containing feed or in the iso-alpha-acid product phase, either in solvent-free conditions or in the presence of water, carbon dioxide, or an organic solvent or a mixture thereof. The resulting mixture is subjected to a temperature of at least 293 K, preferably under an inert atmosphere, for a time sufficient to effect high conversion of the alpha-acid reactant into the iso-alpha-acid product. The molar ratio of alpha-acid to earth alkaline metal (Mg, Ca, Sr, Ba) varies preferably between 0.2 and 20. After the isomerization process, the heterogeneous alkaline earth metal based catalyst can be quantitatively separated from the iso-alpha-acid product phase by liquid-solid separation techniques.

  • Patent number: 8389209
    Abstract: Devices for detecting analytes or analogues thereof in a biological sample are disclosed. The device includes a solid support. The solid support has several juxtaposed zones. The sample is able to migrate from a sample receiving zone towards a detection zone. The analyte, if present, is detected in the detection zone. Both zones have material allowing a capillary flow of the sample through the zones. In between the zones, there is an intermediate zone of transport of the sample which is free from any capillary material. This allows the ample to migrate by gravitational forces on the support laid in a vertical position. Methods for detecting analytes or analogues thereof in a biological sample using the device are also disclosed.

  • Patent number: 7932093
    Abstract: The present invention relates to methods and devices for detecting one or more analytes in a biological sample, preferably a clean liquid sample. This invention in particular relates to improved rapid tests such as “dipsticks”, “lateral flow” devices and “flow-through” devices. The invention in particular relates to oligochromatographic devices that make use of a peptide- or hapten-coupled oligonucleotide and a reagent specifically recognizing the hapten or peptide and a conjugated probe that hybridizes specifically to a target sequence. It allows to detect specifically the presence of a polynucleotides directly or after molecular amplification steps with the use of a specific genuine internal control and a chromatographic control.
