Patent number: 8128892Abstract: A hand-held, multi-channel pipettor has an electronically controlled motor to reposition pipette tips for different center to center spacing. Each repositionable tip fitting assembly has a cam following pin that is driven by cam tracks in a motor driven roller drum. Stationary ports for the multiple aspiration cylinders are strategically placed to simplify management of flexible tubes leading to the repositionable pipette tip fitting assemblies. The pipettor has a user interface that can be operated conveniently by one hand to reposition pipette tips. It has a pipette tip ejection mechanism with a sinusoidal stripper bar.Type: GrantFiled: August 29, 2011Date of Patent: March 6, 2012Assignee: Integra Biosciences Corp.Inventors: David E. Butz, Gregory Mathus, Richard Cote, George P. Kalmakis

Patent number: 8122779Abstract: A hand-held electronic pipettor is designed particularly to be programmed and operated with one hand for the convenience of the user. It uses a capacitance touchpad control for programming, and a separate run button for the operating mode. Internal components are located so that the center of gravity of the pipettor is located within the palm of the user. Flash memory stores an empirically derived table that correlates aspiration volume to motor steps and a separate empirically derived table the correlates dispensing volumes to motor steps.Type: GrantFiled: April 13, 2009Date of Patent: February 28, 2012Assignee: Integra Biosciences Corp.Inventors: Gary E. Nelson, George P. Kalmakis, R. Laurence Keene, Joel Novak, Kenneth Steiner, Jonathon Finger, Gregory Mathus, Richard Cote

Publication number: 20110268627Abstract: A manually directed, multi-channel electronic pipetting system is designed to transfer liquids from a standard multi-well plate, deep-well plate or reservoir into another multi-well plate. The preferred pipetting head includes an array of 96-tip fittings. A deck with at least one but preferably two or more wellplate nesting receptacles holds one or more multi-well plates or reagent reservoirs for access by an array of disposable pipette tips mounted to the pipetting head. The electronic motion control system includes a control handle that is mounted to a load cell, the carriage for the pipetting head and is held in the palm of the user. In use, the user grasps the control handle and operates the system in a manner similar to one using a handheld electronic pipettor.Type: ApplicationFiled: May 3, 2011Publication date: November 3, 2011Applicant: Integra Biosciences Corp.

Publication number: 20110268628Abstract: A manually directed, electronic multi-channel pipettor uses servo controlled motors to drive a carriage and pipetting head in response to a user's manipulation of a control handle. The pipetting head include an array of tip fittings, e.g. 96. The system includes a check processor to avoid unintended motion in case of system faults or crashes. The system requires substantial force to attach the array of tips, and therefore includes controls that require both of the user's hands be occupied during the tip attachment process.Type: ApplicationFiled: May 3, 2011Publication date: November 3, 2011Applicant: Integra Biosciences Corp.

Publication number: 20110076205Abstract: A pipette tip mounting shaft includes outwardly circumferentially extending locking lobes over which the pipette tip collar is mounted. The locking lobes preferably include an inclining ramp portion that gently flexes and distorts the pipette tip collar out-of-round as the mounting shaft is inserted into the pipette tip, rather than the stretching tip collar. Each locking lobe also includes a declining ramp portion which extends upward along the mounting shaft. The peak of the lobes is preferably curved. When the pipette tip is fully mounted on the mounting shaft, a locking ring on the inside surface of the tip collar engages the declining ramp of the lobes to provide an over-center engagement, however, the required ejection force is small.Type: ApplicationFiled: September 29, 2009Publication date: March 31, 2011Applicant: VIAFLO CORPORATIONInventors: Terrence Kelly, Richard Cote, Gregory Mathus

Patent number: 7687927Abstract: An electrical architecture for an aircraft is provided. The electrical architecture is particularly suitable for relatively small, compact, and lightweight aircraft. In one embodiment, the electrical architecture includes an electrical generator component coupled to the aircraft engine, and an air compression system coupled to the electrical generator component. The electrical generator component is configured to receive mechanical power from the engine and to generate a constant frequency AC electrical power from the engine mechanical power, and the air compression system is configured to receive the constant frequency AC power as an input and, in response thereto, produce a pressurized air output having variable characteristics (for example, a variable flow rate or a variable air pressure).Type: GrantFiled: November 21, 2007Date of Patent: March 30, 2010Assignee: The Boeing CompanyInventors: Mark S.

Patent number: 7662343Abstract: The invention relates to a pipette tip mounting shaft configuration and a disposable pipette tip having a matching configuration. The mounting shaft includes a locking section located above a lower sealing section. The locking section has outwardly extending locking lobes circumferentially spaced around the mounting shaft and located above a stop member that separates the lower sealing section from the upper locking section. When the mounting shaft is fully inserted into the collar of the mating disposable pipette tip, the tip locks onto the mounting shaft. The bore of the pipette tip includes a circumferential shelf separating its upper collar from the tip sealing area which is located below the circumferential shelf. The locking lobes gently flexes and distorts the pipette tip collar out of round as the mounting shaft is inserted in the pipette tip, rather than stretching the tip collar.Type: GrantFiled: October 24, 2006Date of Patent: February 16, 2010Assignee: Viaflo CorporationInventors: Gregory Mathus, Terrence Kelly, Richard Cote

The mounting shaft includes a locking section located above a lower sealing section. The locking section has outwardly extending locking lobes circumferentially spaced around the mounting shaft and located above a stop member that separates the lower sealing section from the upper locking section. In certain embodiments, the diameter of the mounting shaft below the stop member is reduced in order to lessen insertion and ejection forces, which is particularly helpful for hand-held multi-channel pipettors. In these embodiments, the lower sealing section contains either a frustoconical sealing section, or an annular groove and a sealing ring, such as a flouroelastomeric O-ring seal.Type: GrantFiled: November 2, 2007Date of Patent: February 16, 2010Assignee: Viaflo CorporationInventors: Gregory Mathus, Terrence Kelly, Richard Cote
