  • Publication number: 20180328857
    Abstract: In order to inspect a substrate, an image information of a substrate before applying solder is displayed. Then, at least one inspection region on the substrate is image-captured to obtain an image of the inspection region that is image-captured. Then, image information that is to be displayed is renewed and the renewed image information is displayed. And, in order to inspect a foreign substance, obtained image of the inspection region is compared with a reference image of the substrate. Therefore, an operator can easily catch a region corresponding to a specific region of the image that is displayed, and easily detect a foreign substance on the substrate.

  • Publication number: 20170261655
    Abstract: A wavelength multiplexing device is disclosed. When light is irradiated on a first longitudinal end region of a metal nano-structure, surface plasmon polaritons are generated in the first longitudinal end region. The surface plasmon polaritons and the light are coupled with each other to form first coupled surface plasmon polaritons, wherein the first coupled surface plasmon polaritons propagate along and on a surface of the metal nano-structure. When the first coupled surface plasmon polaritons reach a two-dimensional material layer, excitions are induced in the two-dimensional material layer, wherein the induced excitions and the first coupled surface plasmon polaritons are coupled with each other to form second coupled surface plasmon polaritons. The second coupled surface plasmon polaritons propagate along and on a surface of the metal nano-structure toward a second longitudinal end thereof.

  • Patent number: 9419464
    Abstract: Disclosed herein is a wireless charging system that includes a transmission device including a primary coil and a reception device including a secondary coil, wherein the transmission device determines the presence or absence of the reception device upon receiving the remaining amount of current supplied from the primary coil to the secondary coil, and controls a voltage input to the primary coil based on the determination results. The wireless charging system can generate a sensing signal for determining the presence and absence of the reception device by measuring the amount of current applied from the transmitter coil to the receiver coil through the detection unit. Thus, the receiver controller of the wireless charging system can accurately determine whether to transmit power by comparing the sensing signal provided from the detection unit with a reference signal, thus reducing power consumption.
