  • Patent number: 11474412
    Abstract: Disclosed by the present invention is an ultra-wideband white noise source based on a slicing super-continuum spectrum. The entropy source used is a super-continuum spectrum photon entropy source having a coverage range of several hundreds of nm, white noise can thus be generated in a wide frequency range, thereby effectively avoiding the bandwidth bottleneck of an electronic device. By separately adjusting the filter centers of two optical filters, the center frequency for generating the white noise can be adjusted so as to get adapted to different working situations. High bandwidth white noise can be generated by simply filtering the super-continuum spectrum and performing photoelectric conversion, and in comparison with the previous solutions, the solution of the present invention is simpler and can be easily implemented.

  • Publication number: 20140267095
    Abstract: A method for searching for icons relating to applications in an electronic device is computer-implemented. When a currently displayed interface of the electronic device is an application icon interface including a plurality of icons, an input touch is determined to be either an already-recorded user-defined touch or a system-defined touch. System-defined touches have automatic consequences. A relationship table is searched to find one or more icons related to the input touch when the input touch is determined to be a previously-recorded user-defined touch. A window is displayed to simultaneously show one or more found icons on the touch screen for the convenience of the user, avoiding any page-up or page-down operation.
