Publication number: 20120291565Abstract: A system and method for valving on a sample processing device. The system can include a valve chamber, a process chamber, and a valve septum located between the valve chamber and the process chamber. The system can further include a fluid pathway in fluid communication with an inlet of the valve chamber, wherein the fluid pathway is configured to inhibit a liquid from entering the valve chamber and collecting adjacent the valve septum when the valve septum is in a closed configuration. The method can include rotating the sample processing device to exert a first force on the liquid that is insufficient to move the liquid into the valve chamber; forming an opening in the valve septum; and rotating the sample processing device to exert a second force on the liquid to move the liquid into the valve chamber.Type: ApplicationFiled: May 18, 2012Publication date: November 22, 2012Inventors: Peter D. Ludowise, Jeffrey D. Smith

Publication number: 20120291568Abstract: Sampling arrangement adapted for extracting a fluid sample from a fluid flowing in a flow path (13). The arrangement comprises a sampling valve (110), such as a ball valve, comprising an outer body and an inner body rotationally supported within it. The inner body is rotationally supported about a rotation axis and comprises a cavity (119) with a first opening (119b) adapted to be rotated into and out of fluid connection with the flowing fluid, and a second opening (119c) which faces in a direction parallel to the rotation axis of the inner rotating body.Type: ApplicationFiled: February 4, 2011Publication date: November 22, 2012Inventor: Eivind S. Gransæther

Publication number: 20120291570Abstract: A method for assembling a sensor assembly includes providing a sensing device configured to measure at least one variable. The method also includes at least partially enclosing a magnetic material within an enclosure. At least a portion of the enclosure is manufactured from a material having a permeability that facilitates forming a magnetic field therein. The method also includes coupling the sensing device to a first portion of the enclosure. The enclosure includes at least one second portion that is movable with respect to the first portion of the enclosure such that a magnetic coupling force is induced external to the enclosure to facilitate coupling the sensor assembly to a magnetic surface.Type: ApplicationFiled: May 20, 2011Publication date: November 22, 2012Inventors: Jacob John Kittleson, Shankar Chandrasekaran, Munish Vishwas Inamdar

Publication number: 20120291571Abstract: Disclosed is a combination of six substantially identical interconnected rotating masses, with a pair each of the rotating masses being configured to rotate in one of each of the three planes (X, Y, and Z). Regardless of the orientation of the six masses, each pair of the six interconnected rotating masses may share substantially the same center of gravity and generate a separate yet interactive kinetic energy and angular momentum in each of the three planes, thereby providing resistance to rotational forces from external sources. This is known as “equal force presence.” In one embodiment, the rotating masses are ring-like masses. In alternative embodiment, the rotating masses are solid masses, similar to flywheels.Type: ApplicationFiled: August 4, 2012Publication date: November 22, 2012Inventors: MARTIN PENG, Kelly Tippett
