  • Patent number: 9141797
    Abstract: Detection of fake antivirus includes classifying text content of a user interface of an application program and scanning files associated with the application program for suspicious code. The user interface may be a graphical user interface (GUI) window of the application program. The text content may be obtained from a painted portion of the GUI window and by intercepting text changing operations performed on the GUI window. The text content may be input to a learning model to determine whether or not the application program belongs to the antivirus category. The application program is deemed to be fake antivirus when the application program is classified as belonging to the antivirus category and has a file with suspicious code.

  • Patent number: 8666204
    Abstract: An optical transmission module includes a semiconductor substrate, a first film layer, an electronic component layer and a waveguide structure. The electronic component layer is used for converting a first electrical signal into an optical signal. The waveguide structure is formed on the first film layer, and includes a first reflective surface, a waveguide body and a second reflective surface. After the optical signal is transmitted through the semiconductor substrate and the first film layer and enters the waveguide structure, the optical signal is reflected by the first reflective surface, transmitted within the waveguide body and reflected by the second reflective surface. After the optical signal reflected by the second reflective surface is transmitted through the first film layer and the semiconductor substrate and received by the electronic component layer, the optical signal is converted into a second electrical signal by the electronic component layer.

The optical signal generated from the signal conversion unit sequentially passes the first film, the semiconductor substrate and the second film and enters the optical waveguide structure. Then, the optical signal is reflected by the reflector and transmitted in the waveguide body to be outputted. Alternatively, the optical signal is transmitted in a reverse direction from the optical waveguide structure to the signal conversion unit.
