Publication number: 20210278431Abstract: An insert mounted in a mixing cup and used by an automated chemical analyzer for removing a targeted component of a liquid sample includes a porous matrix formed of or carrying in an immobilized state functionalized particles having properties such that the targeted component of the liquid sample adheres to the functionalized particles. When the liquid sample is expelled from a disposable tip fitted on the end of a pipette forming part of the automated chemical analyzer into the mixing cup, the liquid sample is drawn into the matrix of the insert by capillary action, whereupon the targeted component of the liquid sample adheres to the immobilized functionalized particles of the matrix.Type: ApplicationFiled: March 8, 2021Publication date: September 9, 2021Inventors: Jesse Daniel Faller, Robert W. Lachapelle, Dominic Pelletier

Publication number: 20210275979Abstract: A method using a chemical analyzer for removing a component of a liquid sample which may interfere with a test performed on a test assay includes the steps of adding the liquid sample to a sample cup, transferring a volume of the liquid sample to a mixing cup containing an IMAC (Immobilized Metal Affinity Chromatography) resin containing porous beads to form a sample/resin solution in the mixing cup, using a pipette of the chemical analyzer to repeatedly aspirate the sample/resin solution into a disposable pipette tip of the pipette and expelling the sample/resin solution from the pipette tip into the mixing cup to achieve a mixed sample/resin solution in the mixing cup, and allowing the mixed sample/resin solution in the mixing cup to rest undisturbed so that the interfering component of the liquid sample adheres to the porous beads and the beads settle to a bottom portion of the mixing cup, resulting in a refined liquid sample devoid of the interfering component and occupying an upper portion of the mixingType: ApplicationFiled: March 8, 2021Publication date: September 9, 2021Inventors: Pamela Ann Cacavas, Lucius S. Fox, Robert W. Lachapelle, Wendy O'Malley LePage, Evan M. Peck, Dominic Pelletier, Eric Allen Steva, Murthy V.S.N. Yerramilli

Patent number: 9151769Abstract: An automated method for calibrating in real time a diagnostic analyzer includes the steps of receiving diagnostic results of patient samples calculated by the analyzer using pre-set parameters of the analyzer, and calculating the centroid of the analyzer's diagnostic results. The centroid of the analyzer's diagnostic results is subtracted from a centroid of diagnostic results of a field population of comparable analyzers to obtain a bias in the centroid of the analyzer's diagnostic results. The bias is compared to predetermined limits. Should the bias fall outside the predetermined limits, an optimization factor is derived and applied to the analyzer's diagnostic results to obtain optimized results from the analyzer without changing the pre-set parameters of the analyzer.Type: GrantFiled: July 13, 2012Date of Patent: October 6, 2015Assignee: IDEXX Laboratories, Inc.Inventors: Jeremy Hammond, Dominic Pelletier, Jason Aguiar

Patent number: 7794664Abstract: A pipette tip includes a main body having an upper end, a lower end and a sidewall extending between the two ends. A bore extends axially through the main body between the upper and lower ends. The lower end has a bottom surface in which is formed a central opening that communicates with the axial bore to allow the passage of fluid therethrough. The bottom surface is formed with at least one groove that may be concentrically disposed or spirally disposed about the central opening. The at least one groove acts to inhibit fluid passing through the central opening from at least partially flowing along the outer surface of the sidewall from the central opening toward the upper end of the main body of the pipette tip.Type: GrantFiled: November 15, 2007Date of Patent: September 14, 2010Assignee: IDEXX Laboratories, Inc.Inventors: Dominic Pelletier, Jeffrey Phelps, Jason Aguiar, Jeremy Hammond, William J. Traigle, Chandler G. Sinnett

Publication number: 20050046830Abstract: A polarized material inspection device that includes a light source, a first polarizing filter disposed within the optical path of the light source, a frame into which a second polarizing filter is disposed, and a support for positioning the frame such that an object may be viewed through the second polarizing filter. In the preferred embodiment, the first polarizing filter is rotatable through a ninety degree arc such that planes of polarization may be adjusted to be parallel or orthogonal to one another. The preferred embodiment also includes a light illumination assembly having a rotatably mounted linear polarizer at the polarizing output end. This light assembly is attached to a portion of the frame and may be adjusted such that the beam of light is directed to the desired portion of the surface. Within the frame is mounted a fixed linear polarizing filter of sufficient size to allow the entire illuminated surface to be viewed.Type: ApplicationFiled: December 29, 2003Publication date: March 3, 2005Inventors: John Karp, Dominic Pelletier

Patent number: 5814910Abstract: A cooling vane for a rotating electric machine and method for attachment. In one embodiment the cooling vane is a corrugated ribbon of thermally conductive material having a plurality of projection points positioned along one edge of the corrugated ribbon. In another embodiment the vane is periodically twisted to bring a portion of the vane parallel with the plate to which the vane is to be welded. In one embodiment the cooling vane is welded to a stator plate of the machine by positioning the cooling vane perpendicularly adjacent the grounded stator plate and applying a high current source to the cooling vane in the region of the projection point. The high current flow through the projection point welds the cooling vane to the stator plate. A plurality of these cooling vanes are welded to the stator plate radially around the surface of the plate to provide a large surface area and to turbulate the fluid flow for the dissipation of heat which is generated within the machine during operation.Type: GrantFiled: September 6, 1995Date of Patent: September 29, 1998Assignee: Eldim, Inc.Inventor: Dominic Pelletier
