Patent number: 8273294Abstract: A microfluidic circuit cartridge having 3-D hydrodynamic focusing. The cartridge may be fabricated with injection-molded or other molded layers providing a 3-D structure. A flow channel on the card may have a sample core flowing in a fluid of a flow channel for analysis. The sample core may be adjustable in position within the channel with one or more jets or channels of fluid being injected into the flow channel. The jets may also adjust the size of the sample core. There may be a hemoglobin measurement mechanism or card with a cuvette.Type: GrantFiled: June 30, 2006Date of Patent: September 25, 2012Assignee: Honeywell International Inc.Inventors: Aravind Padmanabhan, Ron L.

Patent number: 6227809Abstract: This invention provides a method by which the performance of reciprocating NMPV (No-Moving-Parts-Valve) micropumps can be optimized for a given choice of valve design, e.g. for diffuser/nozzle valves, rectifier valves etc. The method can more generally be used to design and produce NMPV micropumps with structures optimized for maximal pump performance. The method can further be used to design and construct NMPV pumps significantly smaller in size than those currently available to the art without significant loss in pump performance.Type: GrantFiled: November 13, 1998Date of Patent: May 8, 2001Assignee: University of WashingtonInventors: Fred K.

Patent number: 4836167Abstract: An engine/governor friction damper mechanism provides for a method of reducing hunting and searching in a governor controlled engine/generator set. The preferred method comprises a modification in a conventional arrangement utilizing a governor rod and pivotal connection with a crank arm on a throttle control assembly. Friction to pivotal movement of the governor rod with respect to the crank arm is provided by means of a spring-loaded friction washer member arrangement.Type: GrantFiled: August 31, 1987Date of Patent: June 6, 1989Assignee: Onan CorporationInventors: Paul F. Huffman, Ron L. Bardell

Patent number: 4793309Abstract: A method of damping governor over compensation and searching is an engine/generator set comprises the provision of an eddy current damper in association with a governor member of the system. The preferred eddy current damper comprises a governor arm having an eddy current plate on one end thereof, the plate being oriented to move through a magnetic field generated by an industrial magnet mounted on the engine/generator set. As the governor arm moves in response to changes in engine speed the eddy current plate is passed through the magnetic field, the generated eddy current causing resistance to motion and a damping effect. Through a conventional linkage mechanism, the damping effect is translated to control of the engine throttle. As a result, over-compensation is generally reduced and/or searching is inhibited.Type: GrantFiled: August 31, 1987Date of Patent: December 27, 1988Assignee: Onan CorporationInventors: Paul F. Huffman, Ron L. Bardell
