  • Patent number: 7149681
    Abstract: This invention discloses a computer translation method and system for resoving word ambiguity. During translating a text in a first language, checking whether or not the word to be translated or the sentence containing the word has additional related text that is associated by a linkage. When the meaning of the word can not be uniquely determined in a second language by analyzing the context than the related text is obtained according to the linkage and the word is translated using both the immediate text and the related text. The linkage mechanism is described as a hyperlink in a HTML document.

  • Patent number: 6972862
    Abstract: A portable fax machine includes a pen-based input device, having a writing pen and a writing pad, enabling a user to write documents for fax transmission on the writing pad by means of the writing pen. The input device is capable of generating data representative of the moving trace of the writing pen. An encoder transfers the data representative of the moving trace of the writing pen into fax data format. A dialer inputs the fax number of a destination to set up a connection. A fax transmission device transmits to the destination the data in the fax data format output by the encoder.
