  • Patent number: 10053483
    Abstract: Provided in the present invention are novel key intermediates of selamectin and the preparation method thereof. Also provided is a new synthesis process, using doramectin as a starting material, and obtaining selamectin via hydrogenation, oxidation, oximation and desugaring. The new process of the present invention has few steps, and is simple to operate, high in yield, low in cost and causes little pollution, and is more suitable for large scale industrial production.

  • Publication number: 20170270092
    Abstract: The disclosed system provides an improved method for text input by using linguistic models based on conditional probabilities to provide meaningful word completion suggestions based on previously entered words. The system uses previously entered n-grams, where n>=2, to generate a list of candidate words matching a current user input. The candidate words are based on one or more conditional probabilities, where the conditional probabilities show a probability of a candidate word following a previously entered n-gram. The system displays the list of candidate words to the user and allows the user to select a desired word for entry. The system also utilizes the context of the text entry to select the candidate words.

  • Patent number: 8103499
    Abstract: To enter Chinese text, a user enters the corresponding phonetic spelling via telephone style keypad. Some or all keys represent multiple phonetic letters. In disambiguating entered key presses to yield a valid phonetic spelling, a computer divides the key presses into segments, while still preserving key press order. Each segment must correspond to an entry in a dictionary of Chinese characters, character phrases, and/or character components such as radicals or other predetermined stroke groupings. Upon arrival of a new key press that cannot form a valid entry when appended to the current segment, key presses are incrementally reallocated from the previous segment. As for already-resolved segments occurring prior to the previous and current segments, these are left intact. After each shifting attempt, the computer reinterprets key presses of the last two segments, and accepts the new segmentation if the segments form valid dictionary entries.

  • Patent number: 7395203
    Abstract: A system and method for inputting Chinese characters using Pinyin without requiring the entry of a delimiter key between Pinyin entries in a reduced keyboard is disclosed. The system searches for all possible single or multiple Pinyin spellings based on the entered Latin alphabets. Once the user has completed the inputting of the Pinyin spellings for desired Chinese phrase or characters, all possible matching phrases or characters are displayed on screen and off-screen due to screen size. The user then scrolls through a list of matching phrases or characters and selects the desired one by clicking.

  • Publication number: 20080154576
    Abstract: A computer-driven system includes different modes interpreting user entered text according to different corresponding vocabularies. Each mode may additionally include a different modality for ultimately resolving and completing the input. Each mode presents the user with a different interpretation of user entered text, according to the associated vocabulary. Displayed output is limited to one or another of the modes in accordance with user instructions to switch between modes.

  • Publication number: 20060062461
    Abstract: A handwritten Chinese character input method and system is provided to allow users to enter Chinese characters to a data processor by adding less than three strokes and one selection movement such as mouse clicking or stylus or finger tapping. The system is interactive, predictive, and intuitive to use. By adding one or two strokes which are used to start writing a Chinese character, or in some case even no strokes are needed, users can find a desired character from a list of characters. The list is context sensitive. It varies depending on the prior character entered. Compared to other existing systems, this system can save users considerable time and efforts to entering handwritten characters.

  • Publication number: 20060018545
    Abstract: The invention provides a stroke and phonetic text input entry system that has substantially the same definition of stroke match as that used in T9, where the input is a phrasal input rather than a character input. The invention solves the problem of Chinese phrasal stroke and phonetic text input by allowing users to enter an arbitrary number of strokes for each character in a phrase, where each character is separated by a delimiter. In this way, the invention provides a system that is easily learned and efficiently applied. Thus, the invention makes it possible for users to enter multiple characters while keeping their single character input habits. Each Chinese character has a standard stroke sequence in Guo Biao (GB), which is the standard for mainland China, or multiple sequences for BIG5 Chinese Character Encoding for Traditional (Complex) Characters, which is the de facto standard in Taiwan but not used in mainland China.
