    • An apparatus and method for dispensing a discrete volume of fluid. The apparatus includes a pump operable in discrete cycles, a power source connected to the pump, and a controller connected to at least one of the pump and the power source. The controller is configured to vary the power provided from the power source to the pump during at least a portion of each discrete cycle based on characteristics of the pump and the fluid. For example, the controller may vary power by controlling the duration of the provision of power, or by controlling the amplitude of the power. Varying the power is intended to improve the accuracy of the discrete volume of fluid dispensed. Correspondingly, the method of dispensing a discrete volume of fluid includes receiving information pertaining to the fluid to be dispensed, and adjusting a provision of power to a pump based on the information. The method may include adjusting the duration of the provision of power, or adjusting the amplitude of the provision of power.
    • 用于分配离散体积的流体的装置和方法。 该装置包括以离散循环操作的泵,连接到泵的电源以及连接到泵和电源中的至少一个的控制器。 控制器被配置为基于泵和流体的特性,在每个离散循环的至少一部分期间改变从电源向泵提供的功率。 例如,控制器可以通过控制提供功率的持续时间,或通过控制功率的幅度来改变功率。 改变功率旨在提高分配的分散体积的精度。 相应地,分配离散体积的流体的方法包括接收与要分配的流体有关的信息,以及基于该信息调节向泵提供功率。 该方法可以包括调整提供功率的持续时间,或者调整提供功率的幅度。
