    • A method and apparatus for micro-aeration of large scale fermentation systems is provided. The micro-aeration system includes a fermentation reactor, a sparging apparatus, and a micro-aeration gas mixture delivered to the fermentation reactor via the sparging apparatus. The micro-aeration gas mixture is a very low oxygen concentration mixture comprising an oxygen containing gas and an inert carrier gas that is preferably recycled through the fermentation reactor. The inert carrier gas is preferably nitrogen whereas the oxygen containing gas is oxygen or and is introduced to the fermentation reactor at a minimum superficial velocity of about 0.02 m/sec to produce a uniform dispersion of the oxygen/air throughout the fermentation broth while concurrently mixing the entire fermentation broth. The micro-aeration method and apparatus further comprises a controller operatively coupled to one or more control valves for regulating the micro-aeration conditions in the fermentation reactor.
    • 提供了一种用于大规模发酵系统微通气的方法和装置。 微曝气系统包括通过喷射装置输送到发酵反应器的发酵反应器,喷射装置和微通气气体混合物。 微通气气体混合物是包含含氧气体和惰性载气的非常低的氧浓度混合物,其优选通过发酵反应器再循环。 惰性载气优选为氮气,而含氧气体为氧气,或以约0.02m / sec的最小表观速度引入发酵反应器,以产生氧气/空气在整个发酵液中的均匀分散,同时混合 整个发酵液。 微曝气方法和装置还包括操作地耦合到一个或多个控制阀的控制器,用于调节发酵反应器中的微通气条件。

    • A vibration frequency adjusting system and method measures energy of a vibration generated by a vibrator of an electronic device, and converts the vibration energy to a level of electric charge. The system and method further compares the level of electric charge with preset electric charge thresholds, and adjusts the level of electric charge to a preset level of electric charge according to the comparison. Then, the system and method converts the adjusted preset level of electric charge to a voltage, and outputs the voltage to vibrator, so as to adjust the frequency of the vibration according to the voltage.
    • 振动频率调节系统和方法测量由电子设备的振动器产生的振动的能量,并且将振动能量转换成电荷水平。 该系统和方法进一步比较电荷水平与预设电荷阈值,并根据比较将电荷水平调整到预设电荷水平。 然后,系统和方法将经调整的预设电平电平转换为电压,并将电压输出到振动器,以便根据电压调节振动频率。
