Patent number: 9631611Abstract: Systems and methods for monitoring operation of a pump, including verifying operation or actions of a pump, are disclosed. A baseline profile for one or more parameters of a pump may be established. An operating profile may then be created by recording one or more values for the same set of parameters during subsequent operation of the pump. A value for a goodness of fit measure comparing the operating profile and baseline profile can be established. If the goodness of fit measure is insufficient, an alarm may be sent or another action taken, for example the pumping system may shut down, etc. An example goodness of fit measure is an R-squared measure.Type: GrantFiled: November 30, 2007Date of Patent: April 25, 2017Assignee: Entegris, Inc.Inventors: Paul Magoon, George Gonnella, James Cedrone

Patent number: 9617988Abstract: 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.Type: GrantFiled: August 22, 2014Date of Patent: April 11, 2017Assignee: Entegris, Inc.Inventors: Marc Laverdiere, James Cedrone, George Gonnella, Iraj Gashgaee, Paul Magoon, Timothy J.

Patent number: 8025486Abstract: Systems and methods for minimizing pressure fluctuations within a pumping apparatus are disclosed. Embodiments of the present invention may serve to reduce pressure variations within a fluid path of a pumping apparatus by avoiding closing a valve to create a closed or entrapped space in the fluid path and similarly, avoiding opening a valve between two entrapped spaces. More specifically, embodiments of the present invention may serve to operate a system of valves of the pumping apparatus according to a valve sequence configured to substantially minimize the time the fluid flow path through the pumping apparatus is closed (e.g. to an area external to the pumping apparatus).Type: GrantFiled: November 20, 2006Date of Patent: September 27, 2011Assignee: Entegris, Inc.Inventors: George Gonnella, James Cedrone, Iraj Gashgaee, Paul Magoon
