  • Patent number: 10764324
    Abstract: A routing system for use in an IoT apparatus is proposed to include a router device. A control module of the router device determines whether to execute a routing process relating to an input message based on environment information, status information and a conflict management mechanism that relate to the router device. In the routing process, the control module executes channel operations when the input message includes a channel management instruction, and executes, when the input message relates to authentication or an application program, a relevant verification procedure or the application program.

  • Patent number: 10338671
    Abstract: A power supply system for a motherboard includes a switching power source, a control circuit, and a switch circuit. The control circuit includes a photocoupler and a comparator. The photocoupler is electrically connected to the switching power source and the comparator. The switch circuit is electrically connected to the comparator and a motherboard. The switch circuit is turned off when the motherboard is in a normal state and turned on when the motherboard is in a standby state. The switching power source outputs a voltage through the control circuit when the switch circuit is turned off. When the switch circuit is turned on, the comparator outputs a first state signal to the photocoupler. The photocoupler thus outputs a first driving signal to the switching power source. The first driving signal causes the switching power source to reduce the voltage.
