  • Patent number: 7173232
    Abstract: A light detection device which can be stably surface-mounted on, for example, a circuit board or the like, and a mounting method thereof are provided. A light-receiving element includes, a transparent conductive electrode (first electrode), a semiconductor layer, and an electrode (first electrode), which are sequentially laminated on a transparent substrate. An insulative substrate includes a terminal electrode (second electrode) which is provided to be exposed at first and second faces of the insulative substrate. The light-receiving element is disposed at the first face of the insulative substrate, and the transparent conductive electrode and the electrode are electrically connected with the terminal electrode exposed at the first face of the insulative substrate. Hence, the light detection device with this structure is surface-mounted on the circuit board such that the terminal electrode exposed at the second face of the insulative substrate connects with an external terminal of the circuit board.

  • Patent number: 6380930
    Abstract: An antenna for wireless communication into a touchpad module. A touchpad module, which can be inserted into an aperture in a laptop computer, includes a touch sensor for detecting touch in a touch sensor circuit for processing signals from the touch sensor. The antenna is connected to a port (input or output) on the touchpad module. The touchpad provides an open aperture for the antenna to communicate with the outside world, without being blocked by the shielding used in a laptop computer.
