  • Patent number: 11204651
    Abstract: A keyboard device includes a membrane circuit board and a key structure over the membrane circuit board. The key structure includes a keycap, a plunger structure, a key pedestal and an elastic element. The plunger structure is arranged between the keycap and the elastic element. At least a portion of the keycap is disposed within a pedestal dust-storage chamber of the key pedestal. At least a portion of the plunger structure is disposed within a guiding chamber of the key pedestal. Due to the relative location between the keycap, the plunger structure and the key pedestal, the path of the dust to enter the guiding chamber is extended or blocked. Consequently, the dust-proof efficacy is enhanced.

  • 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.
