  • Patent number: 11256850
    Abstract: Disclosed are an italic character creation module and method for turning one or more characters selected by a user into italic characters in mobile equipment with a mobile operating system. The italic character creation module includes a screen storage part, an input display part, a waiting-for-processing character obtainment part, a slope generation part, a coordinate system setting part, and a shift processing part. It is possible to calculate a slope on the basis of a tilt angle input by the user, set corresponding 2D coordinate systems, and perform shift processing on the characters waiting for processing chosen by the user in the corresponding 2D coordinate systems so as to create italic characters.

  • Patent number: 11249697
    Abstract: A printing system and a printing method are provided. The user terminal includes a print content processing unit and a sliding print content conversion unit, and the handheld printer includes an inkjet printing unit that performs inkjet printing at a predetermined inkjet width in a sliding direction when performing sliding print. The print content processing unit determines the number of sliding print motions and sequentially generates bitmaps corresponding to the respective sliding print motions based on the respective print content mode and the inkjet width, and generates bitmap format instructions corresponding to the respective bitmaps. The sliding print content conversion unit converts pixels in the bitmaps into binary data to form sliding print content. The handheld printer sequentially prints the respective sliding print content based on the respective bitmap format instructions and the print content mode.

  • Patent number: 9204492
    Abstract: A method for supporting handover from macro Node B to home Node B is proposed according present invention, comprising: informing, by a source radio network control node of a UE1 the UE of configuration parameters of a cell to be measured and indicating the UE to report a unique ID of the measured cell; measuring, by the UE, a signal from the home Node B, and after reading the home Node B's unique ID from the home Node B's system information, reporting the measurement result to said source radio network control node of the UE, said measurement result including the home Node B's unique ID; and sending, by said source radio network control node, a message to a destination radio network control node of said home Node B specified by said unique ID, so that the destination radio network control node can establish radio bearer in the home Node B for the UE.
