  • Patent number: 8558865
    Abstract: The present invention discloses a transmission method in communication of a video phone, which utilize a user input indication messages to include a text message during communication of telephone call, and displays the text message on the calling interface of the terminal, thereby providing transmission of text messages during communication of the video phone. The present invention has improved message interaction between the mobile phones and is suitable for sending and receiving a text message during a telephone call of video mobile phones in the 3G network. The user can directly input words on the calling interface and send them to the other party, and the inputted text message can be directly displayed on the user's calling interface after choosing to send the text message.

  • Patent number: 7763125
    Abstract: The present invention relates to novel non-ferromagnetic amorphous steel alloys represented by the general formula: Fe—Mn-(Q)-B-M, wherein Q represents one or more elements selected from the group consisting of Sc, Y, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, and M represents one or more elements selected from the group consisting of Cr, Co, Mo, C and Si. Typically the atomic percentage of the Q constituent is 10 or less. An aspect is to utilize these amorphous steels as coatings, rather than strictly bulk structural applications. In this fashion any structural metal alloy can be coated by various technologies by these alloys for protection from the environment. The resultant structures can utilize surface and bulk properties of the amorphous alloy.
