Abstract: A characteristic impedance of an electric transmission line is measured by way of extraction. In the method, a first probe and a second probe are provided, wherein the first probe and the second probe are separable and independently operable probes. A first characteristic impedance of a first circuit where a first terminal of the first probe and a first terminal of the second probe are directly interconnected to each other is first measured. Then a second characteristic impedance of a second circuit where the first terminal of the first probe and the first terminal of the second probe are connected to opposite terminals of the electric transmission line, respectively, is measured. The characteristic impedance of the electric transmission line can then be obtained according to the first characteristic impedance and the second characteristic impedance.

Abstract: The present invention provides a relay-based foolproof circuit for over-voltage protection, which is electrically connected between a plug and an electric device, and includes a relay having at least one magnetic core, a coil wound around the magnetic core and two reed switches each having a reed and being normally in a closed state because of the elastic effect of its reed. The relay-based foolproof circuit is able to provide AC power of a first specification (e.g., 110 V AC power) received from the plug to the electric device. However, when AC power of a second specification (e.g., 220 V AC power) greater than the first specification flows through the coil, the coil causes the magnetic core to generate a magnetic force great enough to drive the two reed switches into an open state for stopping the AC power of the second specification from being provided to the electric device.

Abstract: The present invention is to provide a method for automatically configuring a gateway device, wherein the gateway device is installed with configuration software for connecting to a mobile device through a wireless communication unit thereof, and the mobile device is installed with automatic network connection software and configuration information. After activating the automatic network connection software, the mobile device reads the configuration information, searches for currently available wireless networks, establishes a peer-to-peer connection with the gateway device corresponding to the wireless network whose Service Set Identifier (SSID) matches the SSID in the configuration information, and then activates the configuration software and sends the configuration information to the gateway device. Once the configuration software obtains the configuration information, a network connection configuration process of the gateway device is automatically completed. Thus, the mobile device only has to obtain the configuration information of the gateway device in advance by using recognition software.

Abstract: A microstrip antenna includes a substrate, a feedline, an impedance matching structure, and a patch radiator, wherein the substrate has a surface. The feedline is disposed on the surface and extends along a first axial direction. The impedance matching structure is disposed on the surface and has a first end and a second end in the first axial direction, wherein the first end is connected to the feedline. The impedance matching structure has a stepped impedance change. The patch radiator is disposed on the surface, wherein the patch radiator and the second end of the impedance matching structure are adjacent and spaced by a distance in the first axial direction, and the second end of the impedance matching structure is coupled with the patch radiator through the distance. Therefore, a bandwidth of the microstrip antenna could be increased.
