Abstract: Embodiments of the invention provide a system, method and computer program product for reducing the hold-up volume of a pump. More particularly, embodiments of the invention can determine, prior to dispensing a fluid, a position for a diaphragm in a chamber to reduce a hold-up volume at a dispense pump and/or a feed pump. This variable home position of the diaphragm can be determined based on a set of factors affecting a dispense operation. Example factors may include a dispense volume and an error volume. The home position for the diaphragm can be selected such that the volume of the chamber at the dispense pump and/or feed pump contains sufficient fluid to perform the various steps of a dispense cycle while minimizing the hold-up volume. Additionally, the home position of the diaphragm can be selected to optimize the effective range of positive displacement.

Abstract: A control system for controlling electromagnetic pumps, such as electromagnetic driven membrane pumps, has at least one microprocessor and at least one sensor, the microprocessor controlling the power supply to at least one electromagnet whose changes in emitted magnetic field causes at least one moving part, directly or indirectly, to perform an oscillating pumping movement. The control system has at least one positioning sensor which senses the moving part's position in the electromagnetic driven pump. By use of the positioning sensor's measurements, the pump can be controlled with great accuracy. A method for controlling electromagnetic pumps is also provided.

Abstract: One or more techniques and/or systems are disclosed for increasing compressed air efficiency in a pump utilizes an air efficiency device in order to optimize the amount of a compressed air in a pump. The air efficiency device may allow for controlling the operation of the air operated diaphragm pump by reducing the flow of compressed air supplied to the pump as the pump moves between first and second diaphragm positions. A sensor may be used to monitor velocity of the diaphragm assemblies. In turn, full position feedback is possible so that the pump self-adjusts to determine the optimum, or close to optimum, turndown point of the diaphragm assemblies. As such, air savings is achieved by minimizing the amount of required compressed air.
Abstract translation: 公开了一种或多种技术和/或系统，用于在泵中提高压缩空气效率，利用空气效率装置以优化泵中的压缩空气的量。 空气效率装置可以允许通过当泵在第一和第二隔膜位置之间移动时减小供应给泵的压缩空气的流量来控制气动隔膜泵的操作。 传感器可用于监测隔膜组件的速度。 反过来，可以进行全位置反馈，以便泵自动调节以确定隔膜组件的最佳或接近最佳的调节点。 因此，通过最小化所需压缩空气的量来实现节省空气。

Abstract: A portable pumping system provides insulin or other drugs to a user. A shape memory element is used to actuate the pump and an intelligent system controls the actuator in order to minimize stresses within the system and provide accurate and reliable dosage delivery. The control system utilizes various types of feedback to monitor and optimize the position of the pumping mechanisms. Physical design aspects also minimize stress and the combination of the physical design aspects and the intelligent operation of the system results in a lightweight and cost effective pump that may be used in a disposable fashion if desired.

Abstract: A rotary pump is provided having a chamber arranged in a body and a displacement member disposed in the chamber for reciprocating therein. A drive member is used to move the displacement member within the chamber in response to relative rotation between the body and the drive member. A radial valve arrangement may be used to time when the chamber is in fluid communication with inlet and outlet ports on the pump.
