Abstract: A computer data transmission system includes a CPU, a photoelectrical conversion module electrically connected to the CPU, a plurality of I/O interface cards, and a plurality of first optical fibers. The photoelectrical conversion module includes a plurality of photoelectrical conversion units. Each I/O interface card includes at least one photoelectrical conversion unit for converting electrical signals to optical signals or converting optical signals to electrical signals. The first optical fibers connect the photoelectrical conversion units of the I/O interface cards and the photoelectrical conversion units of the photoelectrical conversion module. The photoelectrical conversion unit of the photoelectrical conversion module receives electrical signals outputted by the CPU, and convert the electrical signals to optical signals. The converted optical signals are transmitted to the photoelectrical conversion unit of the I/O interface card, and the photoelectrical conversion unit of the I/O interface card converts the optical signals to electrical signals.

Abstract: A projector includes a case, a projection lens, a shielding plate, and a controller received in the case. The case includes a sidewall defining an aperture. The projection lens is used for projecting a cone of light rays which passes through the aperture and a projection area. The shield plate is positioned on the sidewall. The driver is used for driving the shield plate to any of desired positions ranging from a first position in which the shield plate exposes the aperture to a second position in which the shield plate shields the aperture. The barrier detection device is used for generating a first signal if detecting no barrier presents in the projection area and generating a second signal if detecting a barrier presents in the projection area. The controller is used for controlling the driver to drive the shield plate to the first position if receiving the first signal.
