Publication number: 20150363226Abstract: Methods, systems, and computer program products for training an optimized time estimation system for completing a data processing job to be run on a data processing device that operates within a distributed processing system having a range of platforms. Embodiments include creating a prediction algorithm based upon retrieved operational parameters associated with a data processing job. Embodiments also include retrieving further operational parameters associated with the data processing job. Embodiments include updating the prediction algorithm based on the further operational parameters, in which the prediction algorithm is updated by modifying parameter values associated with variable parameters of the prediction algorithm.Type: ApplicationFiled: June 3, 2015Publication date: December 17, 2015Inventors: Marcus FREAN, David KYDD, Chris TEELING, Josiah JORDAN, Anna TISCH, Peter SOUKALOPOULOS, Peter DE VOCHT, Tim HOGAN, Scott HOUSTON, Dave FELLOWS, Darryl LUNDY, Adrian John

Patent number: 7690405Abstract: An improved multi fluid dispenser for simultaneous dispensing of a plurality of fluids shown and described. The dispenser includes a controller that is linked to a coordinator board. The controller has a memory with a plurality of recipes stored in the memory. A coordinator board is linked to a first module. The first module may include one or two pumps, each connected to a fluid reservoir. The module is then linked in series to a plurality of other modules as well as a manifold module. Each module includes a module board for controlling the pump or pumps of that module. The controller, coordinator board and module boards are all programmed for the simultaneous or sequential pumping of multiple fluids from the reservoirs through outlet nozzles of the manifold in accordance with a recipe selected by the user and retrieved from the memory of the controller.Type: GrantFiled: July 18, 2005Date of Patent: April 6, 2010Assignee: Fluid Management, Inc.Inventors: William A. Miller, Tim Hogan, Christopher Khoo, Ryan Hanawalt, Marty Leider, James R. Cleveland, Anton Obrecht

Patent number: 7261131Abstract: A closure system for a fluid outlet is disclosed which includes a motor threadably connected to a hub which, in turn, is connected to a closure element or cup that provides a sealing cover beneath one or more nozzles. The action of the motor initially lowers the closure element vertically before pivoting the closure element away from the area directly beneath the nozzle or nozzles. After fluid is dispensed, a biasing element pivots the closure element back into place before it is raised vertically again to provide a seal or cover for the one or more nozzles. The hub is designed to pivot only a partial revolution and the pivoting action of the hub and closure element away from the nozzle area overcomes the bias of the biasing element contained within the hub. The biasing element then pivots the hub and closure element back into place before the biasing element raises the hub and closure element to its original position.Type: GrantFiled: March 16, 2004Date of Patent: August 28, 2007Assignee: Fluid Management, Inc.Inventors: James R. Cleveland, Tim Hogan

Publication number: 20070196223Abstract: A nutating pump is disclosed which has a modified piston and housing or casing that provides two distinct pump chambers or areas. Output from the first pump chamber is delivered during a first half of the dispense cycle or the piston movement cycle. A substantial portion of this output is held for delivery by the second chamber during a second part or half of the dispense cycle. Thus, the output generated by the pump is not altered or reduced, it is delivered over the entire piston movement cycle as opposed to prior art pumps which deliver all of the fluid during a first half or first portion of the piston movement cycle. In this way, superior pulse modification is achieved as fluid is delivered across the entire piston movement cycle as opposed to a first half or first portion of the piston movement cycle. In additional embodiments disclosed, two distinct chambers are also provided but each chamber generates its own output as the piston includes two machined or flat sections for active pumping.Type: ApplicationFiled: February 22, 2006Publication date: August 23, 2007Applicant: Fluid Management Operations, LLCInventor: Tim Hogan

Patent number: 6749402Abstract: A fluid dispense system having a computer control system that operatively controls a stepper motor driving a pump. The stepper motor actuates the pump piston through partial revolutions. The computer control system determines the number of stepper motor steps required to pump a desired amount of fluid by the pump by rotating the piston through segments which are less than a full revolution. Further, the controller varies the speed of the stepper motor to avoid splashing of the dispense fluid and motor stalling.Type: GrantFiled: July 30, 2002Date of Patent: June 15, 2004Assignee: Fluid Management, Inc.Inventors: Tim Hogan, Thomas J. Amsler, James R. Cleveland
