  • Patent number: 7302640
    Abstract: A language input architecture converts input strings of phonetic text to an output string of language text. The language input architecture has a search engine, typing models, a language model, and one or more lexicons for different languages. Each typing model is trained on real data, and learns probabilities of typing errors. The typing model is configured to generate a list of probable typing candidates that may be substituted for the input string based on probabilities of how likely each of the candidate strings was incorrectly entered as the input string. The language model provides probable conversion strings for each of the typing candidates based on probabilities of how likely a probable conversion output string represents the candidate string. The search engine combines the probabilities of the typing and language models to find the most probable conversion string that represents a converted form of the input string.

  • Patent number: 7165019
    Abstract: A language input architecture converts input strings of phonetic text (e.g., Chinese Pinyin) to an output string of language text (e.g., Chinese Hanzi) in a manner that minimizes typographical errors and conversion errors that occur during conversion from the phonetic text to the language text. The language input architecture has a search engine, one or more typing models, a language model, and one or more lexicons for different languages. Each typing model is trained on real data, and learns probabilities of typing errors. The typing model is configured to generate a list of probable typing candidates that may be substituted for the input string based on probabilities of how likely each of the candidate strings was incorrectly entered as the input string.

  • Publication number: 20050060138
    Abstract: A language input architecture receives input text (e.g., phonetic text of a character-based language) entered by a user from an input device (e.g., keyboard, voice recognition). The input text is converted to an output text (e.g., written language text of a character-based language). The language input architecture has a user interface that displays the output text and unconverted input text in line with one another. As the input text is converted, it is replaced in the UI with the converted output text. In addition to this in-line input feature, the UI enables in-place editing or error correction without requiring the user to switch modes from an entry mode to an edit mode. To assist with this in-place editing, the UI presents pop-up windows containing the phonetic text from which the output text was converted as well as first and second candidate lists that contain small and large sets of alternative candidates that might be used to replace the current output text.

  • Publication number: 20040086867
    Abstract: Disclosed is a new methodology for detecting and/or quantitating nucleic acid sequences, termed “Reporter Oligo Capturing After Specific Hybridization,” (ROCASH). As described above, the prior art methods for detection of nucleic acid samples are often forced to trade sensitivity in the detection assay to achieve increased specificity. In this method, unlike the prior art methods, the specificity of hybridization and the sensitivity of the detection step are provided by different nucleic acid sequences hybridizing in different steps of the method. Therefore, conditions for these critical steps may be optimized independently of each other.

  • Publication number: 20030009117
    Abstract: The present invention provides a kneading head of massage machine that consists of a connecting rod and a set of spherical heads. One set of the spherical heads includes two and more; all the spherical heads located on ends of the connecting rod in different heights, or all the spherical heads can be integrated with the connecting rod into a whole body. When the massage machine adapting the kneading head is used on the human body, the stepped spherical heads will effort a great pushing force and a great pressing force on surface and deeper skin of the muscle of the human body simultaneously at different heights and positions so as to carry on massage in kneading method with a better effect for meeting the necessaries of the customers.

  • Patent number: 5888740
    Abstract: Disclosed is a method and composition of matter for PCR-based gene dosage analysis. The invention provides internal control DNA sequences that are the same length and same G-C content. The method does not require sized separation of the amplified products. Instead, the method utilizes hybridization and ELISA like colormetric screening. The invention further provides for tightly controlled internal standards for comparing gene dosage by placing one copy of various chromosome markers on one plasmid.
