Abstract: Disclosed herein is an optical interconnecting system for transmitting a large amount of data. The system includes a bidirectional transmitting/receiving circuit that is installed at each of both ends of a data line between chips or boards, selectively receives an electric signal or an optical signal, amplifies and converts the received signal and selectively outputs the signal. The optical interconnecting system integrates a transmitter and a receiver into one bidirectional transmitting/receiving circuit to reduce circuit design and manufacturing costs and decrease power consumption. The system can integrate the bidirectional transmitting/receiving circuit in a highly integrated semiconductor chip and extend it to a multi-dimension multi-channel form to produce a compact package.

Abstract: The present invention relates to a remote controller of a vehicle with a built-in digital camera. The remote controller of the present invention is provided with a built-in digital camera so that it can be used to record the actual scenes of a car accident as images. The built-in digital camera in the remote controller of the present invention comprises a base plate, which comprises a liquid crystal display, a shutter, a lens, a control unit, a memory unit, and an input/output port.
