Publication number: 20090282901Abstract: An apparatus and method for measuring or comparing rheological properties of fluid samples in parallel is disclosed. The apparatus includes a plurality of sensing elements which are comprised of flow channels and reservoirs in fluid communication. The channels provide flow paths for the fluid samples which are initially contained within external reservoirs. The method includes flowing the fluid samples at variable rates and monitoring simultaneously sample flow rates from the reservoirs through a plurality elements for one or more increments of time. The disclosed method is capable of measuring or comparing rheological properties of at least two fluid samples simultaneously. Useful flow rates monitoring devices include optical array sensors and image analysis systems.Type: ApplicationFiled: May 17, 2008Publication date: November 19, 2009Inventor: WILLIAM KEITH LEONARD

Patent number: 7454958Abstract: The invention provides devices and methods for acoustically determining the properties of the contents of one or more reservoirs in a plurality of reservoirs. Each reservoir is adapted to contain a fluid. An acoustic radiation generator can be positioned in acoustic coupling relationship to each of the reservoirs. Acoustic radiation generated by the acoustic radiation generator is transmitted through each reservoir to an analyzer. The analyzer is capable of analyzing a characteristic of the transmitted acoustic radiation and optionally correlating the characteristic to a property of the reservoirs' contents. Properties that may be determined include volume, temperature, and composition. The invention is particularly suited to determining the properties of the contents of a plurality of reservoirs to allow for accuracy and control over the dispensing of fluids therefrom.Type: GrantFiled: September 20, 2004Date of Patent: November 25, 2008Assignee: Labcyte Inc.Inventors: Richard N. Ellson, Richard G. Stearns

Patent number: 7437912Abstract: A method and device for assessing rheological properties of a fluid, including lubricity and viscosity. The invention utilizes a tube into which the fluid is introduced, and relies on tracking the movement of the fluid through the tube either alone or with one or more particles intentionally introduced into the fluid to assess the rheological properties of the fluid. The method and device generally entail flowing the fluid and the optional suspended particle through a passage within the tube, and assessing a rheological property of the fluid within the tube by tracking the movement of the fluid and/or particle through the portion relative to the flow of the fluid through the portion.Type: GrantFiled: July 19, 2005Date of Patent: October 21, 2008Assignee: Integrated Sensing Systems, Inc.Inventors: Douglas Ray Sparks, Nader Najafi
