  • Patent number: 10794593
    Abstract: A vaporization pipe for a kerosene lamp has an oil tube, a thermally conductive tube, and a first passage. The oil tube is made of steel and has a vaporization jet on a top of the oil tube. The thermally conductive tube is mounted in the oil tube and forms a first channel. The first passage is disposed between the oil tube and the thermally conductive tube. The steel oil tube can prevent the vaporization pipe from being softened and bent during the preheating of vaporization pipe or burning of the kerosene, and thus a useful lifetime of the vaporization pipe is prolonged. The thermally conductive tube is made of high-thermal-conductivity material for keeping the vaporization pipe with adequate thermal conductivity and improving a burning rate of kerosene. The first passage allows the kerosene to flow upward, preventing the kerosene from being vaporized incompletely because the kerosene is over pressurized.

  • Patent number: 10021609
    Abstract: The disclosure is related to a method and a system for selecting a communication interface. The method is applicable to a local area network including multiple access points. A main access point is first selected. The main access point acquires every access point's information within a local area network. The information relates to the access points that are in an idle state or not performing a critical task. A target antenna can be selected for performing a specific function. For example, the target antenna can be used to scan for the channels specified in dynamic frequency selection. After that, the scan result may result in changing channels. Through the above mechanism, the resources in every AP within the LAN can be adequately used, and the performance of wireless communication can be effectively improved.
