A quick connector includes a female member and a male member. Since data decisions provided by the decoder are typically more reliable than those provided by the detector, a significant performance improvement is obtained. The CPAP device may operate in continuous mode, bi-phase mode, or automatic mode. The VLC codes the MPEG2 data, using the RUN and the Level to which the target data is added. The liquid crystal display panel 3 controls polarization state of the inputted light and, according to the state, causes the light to pass through another polarization plate 15. The flexible elements of the mirror mount provides a number of advantages and increases the performance capabilities of the first mechanical interface between the mirror mount and the actuator.
