Abstract: A gas detection and cleaning system for a vehicle is disclosed and includes an external modular base, a gas detection module and a cleaning device. The gas detection module is connected to a first external connection port of the external modular base to detect a gas in the vehicle and output the information datum. The information datum is transmitted through the first external connection port to a driving and controlling module of the external modular base, processed and converted into an actuation information datum for being externally outputted through a second external connection port of the external modular base. The cleaning device is connected with the second external connection port through an external port to receive the actuation information datum outputted from the second external connection port to actuate or close the cleaning device.

Abstract: A device for transmitting light signals includes two electrode plates, a spacing structure, a cladding fluid, and a core fluid. The spacing structure, the cladding and core fluids are disposed between the electrode plates. The refractive index of the core fluid is higher than that of the cladding fluid. The core fluid is located on an electrode of one of the electrode plates, and its shape corresponds to the shape of that electrode. The shape and position is changeable and programmable by the electrodes of one of the electrode plates. The core fluid is further surrounded by the cladding fluid, forming an optical waveguide. Via these arrangements, the interface between the core and cladding fluids is much smoother than that between a fluid and a solid, so that the light signals are less likely to scatter while transmitted, in the core fluid. Therefore, the attenuation and reduction of the intensity of the light signals can be decreased. A method for transmitting light signals is also provided.
