  • Patent number: 11218027
    Abstract: A light-emitting wireless charging structure includes a base, a wireless charging module, a light-emitting element and an upper cover. The wireless charging module is disposed on the base. The light-emitting element is disposed on the base adjacent to the wireless charging module. The upper cover covers the wireless charging module and the light-emitting element. The upper cover has a lower surface facing the wireless charging module and an upper surface opposite to the bottom surface. When the light-emitting element emits light, light coming from the light-emitting element passes through the upper cover and forms a mark on the upper surface to indicate the position of the wireless charging module. When the light-emitting element is turn off or kept in an off state, either the mark that has been formed on the upper surface disappears therefrom or no any mark is ever shown on the top surface.

  • Patent number: 10038630
    Abstract: A network system includes a terminal device, a first router, a second router, a first border router, a second border router and a server. The server transmits an updating software to the first and the second border routers through an Internet network. The first border router transmits the updating software to the first router and the second border router transmits the updating software to the second router. The first router transmits the updating software to the terminal device and the second router transmits the updating software to the terminal device. When a version information of the updating software received from the first router and that received from second router are identical, the terminal device executes the updating software. When the version information of the updating software received from the first router and that received from the second router are different, the terminal device does not execute the updating software.

  • Patent number: 7263374
    Abstract: A method of changing the setting of mobile unit by broadcasting message is provided. Firstly, the broadcaster codes the setting information into an application program via message editing such. Then, the message is broadcasted to associated mobile units according to the numbering of the mobile unit. When the starting time is up, the original setting of the mobile unit will be shifted to a situational setting according to the setting information; whereas when the finishing time is up, the situational setting will be shifted back to the original setting and all previous settings will be restored. Lastly, the system terminal receives and writes the mobile phone information into a registry, then broadcasts the setting information to the mobile phone within the specific area, enabling the mobile phone to change relevant settings accordingly. Mobile phones outside the specific area cannot receive the broadcasting signal and will not be affected.
