    • The present invention provides a control device featuring a control module featuring one or more modules configured to provide a first control signal for controlling a first device in order to open or close a second device; and also configured to respond to a change in a parameter sensed in relation to controlling the first device, and to provide a second control signal for controlling the first device based at least partly on the change in the parameter in relation to time. The first device may be a motor; the second device is a valve; and the parameter may be current. In operation, the first control signal is for turning on the motor in order to open or close the valve, and the second control signal is for turning off the motor in order to open or close the valve.

    • The present invention provides a technique using current sensing to control the pressure at constant level without the direct sensing of the pressure. This technique will help to reduce dependency solely on switch or sensor and their non linearity and other associated problems such as the non-repetitive behavior, being affected by EMI etc. The technique includes using a pump controller featuring one or more modules configured to respond to one or more input signals containing information about current provided from a pump; and configured to provide one or more output signals containing information to control the pump to operate at a substantially constant pressure without the direct sensing of pump pressure. The one or more modules control the operation of the pump based at least partly on a table of characteristics related to voltage and current that is calibrated for each pump.
    • 本发明提供了一种使用电流检测来在不直接感测压力的情况下将压力控制在恒定水平的技术。 这种技术将有助于减少仅依赖于开关或传感器及其非线性度和其他相关问题,如不重复行为,受EMI等影响。该技术包括使用一个泵控制器,其特征在于一个或多个模块配置为响应 包含关于从泵提供的电流的信息的一个或多个输入信号; 并且被配置为提供包含信息的一个或多个输出信号以控制泵以基本恒定的压力操作,而不直接感测泵压力。 所述一个或多个模块至少部分地基于与为每个泵校准的电压和电流相关的特性表来控制泵的操作。
