A method and an image sensor circuit for providing a bit stream pulse modulated signal at a controlled bit rate. The embodiment of the present document further correspondingly discloses a multi-stream service concurrent transmission subsystem, system and a multi-interface terminal. The pulse laser apparatus further includes a unit configured to give a loss to energy portions in a wavelength region corresponding to a zero-dispersion wavelength of the rare-earth doped fiber andor a wavelength region longer than the zero-dispersion wavelength within a wavelength spectrum of the laser beam having been chirped in the fiber amplifier. Game uses standard casino dice as random number generators and standard chip sets for betting, as well as game-specific sequentially numbered discs and cylinder markers to indicate winning plays. The washing machine dries a small quantity of the laundry without application of any additional drying pipe or heater.
