Publication number: 20080194426Abstract: A system for performing hybridization assays comprises a cartridge for housing a flow through device, where the cartridge includes a test fluid chamber for facilitating a substantially uniform flow of a test fluid mixture through the flow through device, and a fluidics station to deliver the test fluid mixture to the cartridge. The cartridge has a chip holder that holds the flow-through device, which has an array of microchannel passages. The chip holder has a support for placement of the flow though device, the test fluid chamber for directing a substantially uniform flow of a test fluid mixture through the array of microchannel passages of the flow through device, and a first port that receives the test fluid mixture. The cartridge has a sealing system for preventing the leakage of the test fluid around the flow through device. The test fluid chamber is defined in part by a spade-like surface having an inlet for the test fluid mixture.Type: ApplicationFiled: February 4, 2008Publication date: August 14, 2008Inventors: Jack Goodman, Matthew Torres, Hongjun Yang, David G. Mateer, Ian Stuart Richard Smith

Patent number: 6491085Abstract: A control system for a vertical vane covering for use in an architectural opening includes a headrail having an upwardly opening channel in which a plurality of carriers are disposed for sliding movement along the length of the headrail. The headrail is of a thin profile with only a minority portion of the carriers being positioned within the hollow interior of the headrail. The carriers are interconnected by a scissors-type linkage to effect uniform separation of the vanes when the covering is expanded across an architectural opening, and each carrier includes a rack and pinion system or a meshing gear system for rotating the vanes suspended thereby. Unique mountings for the endmost vanes allow the endmost vanes to cover the ends of the headrail. Rotation of a tilt wand or translation of a tilt cord results in rotation of a tilt rod via a pair of drive gears or a positive-grip pulley. Rotation of the tilt rod activates the rack and pinion system or the meshing gear system.Type: GrantFiled: March 14, 2000Date of Patent: December 10, 2002Assignee: Hunter Douglas Inc.Inventors: James M. Anthony, Wendell B. Colson, David G. Mateer, Larry J. Delliman, Richard N. Anderson

Patent number: 5532766Abstract: Foldable eyeglasses having a first frame holding a lens and a second frame for holding a lens. The first frame has a first leaf and a second leaf with a predetermined space therebetween. At least one of the first or second leaves has a protrusion for locking the first frame to the second frame. The second frame has a third leaf with a complimentary detent for engaging the protrusion of the first frame. The first and second frames are rotably mounted together by a hinge allowing rotation about an axis extending through the first, second, and third leaves from a folded position wherein the frames are folded together to an open position wherein the third leaf rotates into the space between the first leaf and the second leaf and the protrusion engages the detent to lock the frames together.Type: GrantFiled: September 27, 1995Date of Patent: July 2, 1996Assignee: Al W. PaulsenInventors: David G. Mateer, D. Michael Pogue

Patent number: 5256866Abstract: An optical scanning wand is disclosed that provides improved illumination of the document scanned and improved visual control of the movement of the wand. The wand comprises a handle having a hollow tip disposed at an oblique angle thereto. The tip has a scanning window opening at its distal end that defines the target zone through which the image being scanned should pass. In one embodiment light is directed to the document through the transparent tip. In another embodiment the light is directed toward the document by optical fibers from a light source located behind the wand's light sensor and the tip is cut away to provide viewing window openings.Type: GrantFiled: November 25, 1991Date of Patent: October 26, 1993Assignee: Soricon CorporationInventors: Giuseppe R.
