Abstract: A microfluidic device and sensing method that utilize a resonating tube configured to have sufficient sensitivity to be capable of sensing the volume of a gas present as bubbles in a liquid or the flow rate and/or density of a gas or gas mixture flowing through the tube. The tube has a freestanding tube portion supported above a surface of a substrate so as to be capable of vibrating in a plane normal to the surface of the substrate. As a gas-containing fluid flows through an internal passage of the tube, a drive signal vibrates the freestanding tube portion at a resonant frequency thereof. Coriolis-induced deflections of the freestanding tube portion are sensed relative to the substrate to produce an output corresponding to the sensed deflections, and the drive signal and/or the output are assessed to determine the volume, density and/or flow rate of the gas of the gas-containing fluid.

Abstract: A microelectromechanical system (MEMS) device and a method for operating the device to determine at least one property of a fluid. The device includes a base on a substrate and a tube structure extending from the base and spaced apart from a surface of the substrate. The tube structure includes at least one tube portion and more preferably at least a pair of parallel tube portions substantially lying in a plane, at least one continuous internal passage defined at least in part within the parallel tube portions, and an inlet and outlet of the internal passage fluidically connected to the base. A drive element is operable to induce vibrational movement in the tube structure in a plane of the tube structure and induce resonant vibrational movements in the tube portions. A sensing element senses the deflections of the tube portions when the tube structure is vibrated with the drive element.

Abstract: A system and methods for processing and charting security exchange trading and market information shows security traders if current transactions originated as buy orders or sell orders, and simultaneously indicates traded quantity. Security exchange trading information is received that includes the price, volume and time of each trade. In addition, security exchange market information is received from buyers, specifying bide prices and quantities, and from sellers, specifying asking prices and quantities. The security exchange trading and market information is processed simultaneously and displayed as a continuously updated real-time chart depicting the exchange auction process whereby buyers and sellers agree to trade at specified prices, including details of individual transactions. The chart is formed by plotting each trade at the price traded, and for each plot point shows a distinctive icon indication whether the transaction was initiated by a buyer or seller.

Abstract: A catheter used for treatment of complex vasculature, such as a bifurcated aneurysm, is provided with an inflatable balloon at a distal portion thereof. The shape, location and material of the inflatable balloon are selected such that when inflated, the balloon conforms to the shape of the complex vasculature, or at least a portion thereof, without appreciably deforming the vessel walls. In this manner, the balloon can be used to control flow in the vasculature, for example occluding a selected branch of the vasculature during introduction of material in order concentrate the material and minimize its disbursement by blood flow.

Abstract: A multi-tasking downhole rod guide for centralizing a downhole pump rod production tubing within production tubing, while simultaneously reducing abrasion and deterioration of the production tubing and engendering auxiliary pump-boosting functions—with minimal energy consumption. The rod guide is configured with an elongate helix having a continuous trough-like channel through hydrocarbons flow upwardly under high pressure. As the pressurized hydrocarbons flow through a succession of plates at each equidistant helical level, the elongate helix rotates synchronously with the upwardly flowing hydrocarbons within the production tubing string. A multi-tasking downhole rod guide for centralizing downhole production tubing within a well casing, while simultaneously reducing abrasion and deterioration of the tubing and engendering auxiliary pump-boosting functions—with minimal energy consumption.

Abstract: A device and method capable of sensing the presence of biochem agents, and preferably also capable of delivering precise amounts of one or more antidotes to treat a victim exposed to the agents. The device includes a freestanding tube portion having an internal passage containing a substance selective to a chemical or biological agent so that matter accumulates within the freestanding tube portion when a fluid drawn through the tube portion contains the agent. When vibrated at resonance, the resonant frequency of the tube portion is indicative of the accumulation of matter and thereby the presence of the agent to which the substance is selective. The device then preferably delivers precise amounts of one or more appropriate antidotes to treat the victim. The device is a sufficiently small and lightweight unit to permit being carried by an individual.

Abstract: A process for fabricating multiple microfluidic device chips. The process includes fabricating multiple micromachined tubes in a semiconductor device wafer. The tubes are fabricated so that each tube has an internal fluidic passage and an inlet and outlet thereto defined in a surface of the device wafer. The device wafer is then bonded to a glass wafer to form a device wafer stack, and so that through-holes in the glass wafer are individually fluidically coupled with the inlets and outlets of the tubes. The glass wafer is then bonded to a metallic wafer to form a package wafer stack, so that through-holes in the metallic wafer are individually fluidically coupled with the through-holes of the glass wafer. Multiple microfluidic device chips are then singulated from the package wafer stack. Each device chip has a continuous flow path for a fluid therethrough that is preferably free of organic materials.

Abstract: A pipe guide adapter adds marking slots and marking edges to a pipe guide. The pipe guide adapter includes two body sections joined by a hinge enabling the pipe guide adapter to be in open and closed positions.

The hinge pin allows tie pipe guide adapter to be aligned to the pipe guide. The extended portion of the hinge pin acts as a stop and a spacer between the pipe guide adapter and the pipe guide.
