    • Embodiments of the invention provide a stand-alone controller and a method for controlling a pump motor driven by an alternating current source. The stand-alone controller includes a power terminal for connection with the alternating current source and a load terminal for connection with the pump motor. The stand-alone controller further includes an enable switch to form a power line carrying power from the alternating current source to the pump motor. The stand-alone controller can store a first current being drawn through the power line by the pump motor when a control switch is actuated. A state of the enable switch is based on a comparison of the first current to a second current being drawn through the power line by the pump motor.
    • 本发明的实施例提供了一种独立控制器和用于控制由交流电源驱动的泵马达的方法。 独立控制器包括用于与交流电源连接的电源端子和用于与泵电动机连接的负载端子。 独立控制器还包括使能开关以形成从交流电源向泵电动机承载动力的电力线。 当控制开关被致动时,独立控制器可以存储由泵电动机通过电力线吸取的第一电流。 使能开关的状态基于通过泵电动机通过电力线吸取的第一电流与第二电流的比较。

    • A non-uniform thickness lens has a portion of a peripheral edge trimmed for secure engagement within a groove of blade style frame. Frame parameters are determined, such as by tracing the frame. The frame parameters include the plan layout as well as the contour and width of the engagement groove in the frame. The lens is edged to match the plan shape of the frame. The edged lens is then milled to reduce the thickness of the edge of each lens to a determined thickness along the contour corresponding to the non visual portion of the edge of the lens that will be engaged within the frame. The milled lens will fit securely in place in a blade style frame and without impairing the wearer's vision.
    • 不均匀的厚度透镜具有修剪的边缘的一部分,用于可靠地接合在叶片式框架的凹槽内。 确定帧参数,例如通过跟踪帧。 框架参数包括平面布置以及框架中的接合槽的轮廓和宽度。 镜片边缘与边框的平面形状相匹配。 然后研磨经边缘的透镜,以将每个透镜的边缘的厚度沿着与将在框架内接合的透镜的边缘的非视觉部分相对应的轮廓减小到确定的厚度。 研磨的镜片将牢固地安装在刀片式框架中的适当位置,而不会损害佩戴者的视力。
