Integrated active flux microfluidic devices and methods
InactiveUS6767706B2Rapid and complete exposureQuick and accurate and inexpensive analysisBioreactor/fermenter combinationsFlow mixersAntigenHybridization probe
The invention relates to a microfabricated device for the rapid detection of DNA, proteins or other molecules associated with a particular disease. The devices and methods of the invention can be used for the simultaneous diagnosis of multiple diseases by detecting molecules (e.g. amounts of molecules), such as polynucleotides (e.g., DNA) or proteins (e.g., antibodies), by measuring the signal of a detectable reporter associated with hybridized polynucleotides or antigen / antibody complex. In the microfabricated device according to the invention, detection of the presence of molecules (i.e., polynucleotides, proteins, or antigen / antibody complexes) are correlated to a hybridization signal from an optically-detectable (e.g. fluorescent) reporter associated with the bound molecules. These hybridization signals can be detected by any suitable means, for example optical, and can be stored for example in a computer as a representation of the presence of a particular gene. Hybridization probes can be immobilized on a substrate that forms part of or is exposed to a channel or channels of the device that form a closed loop, for circulation of sample to actively contact complementary probes. Universal chips according to the invention can be fabricated not only with DNA but also with other molecules such as RNA, proteins, peptide nucleic acid (PNA) and polyamide molecules.

Drain cover for generally open flat drainage areas with debris blockage and open drainage portions
InactiveUS8557109B1High strengthLarge apertureFatty/oily/floating substances removal devicesSewerage structuresProbable CaseEngineering
A drain cover having a main drainage surface with relatively larger apertures or openings therein, comprising generally 50 percent of the surface, so that larger debris is accepted into a related drain pipe when a depending skirt portion of the drain cover, having smaller perforations, becomes clogged. In this way a two-layer drainage system for a generally flat surface is provided that allows draining of water and small particulates alone when possible, but upon the clogging of the smaller openings the generally flat surface can be protected from flooding by allowing larger particulates to drain into the main drainage surface. The main drainage surface is held above the flat surface by the depending skirt, at a level of ⅜ to 1 inch above the flat surface. When the depending skirt openings are clogged the water and debris will rise until allowed to drain into the larger openings of the main drainage surface.

A closed photo-bioreactor, which in at least one example comprises a plurality of flexible, repeating, substantially enclosed, parallel chambers flexibly connected along their lengths, where a liquid growth media is substantially still without the need for turbulent mixing of the bulk liquid. In many examples, each is connected into integrated, flexible pipelines that serve to supply gas to the chambers, to vent gas from the chambers, and to fill and drain the individual photo-bioreactor chambers of their liquid contents. In some installations, a bioreactor will be rolled up using, for example, a long rod as a spool, for storage and transportation. Some examples will be manually unfurled and positioned on an angled site including, for example, an earthen berm. In many embodiments, a photo-bioreactor will be manufactured from thin plastics using low cost manufacturing techniques. In at least one example, a photo bioreactor is described in which bubbles with a substantially non-convex shape are introduced to mix the liquid contents.

A device for manipulating a tarpaulin so as to selectively cover and uncover a top aperture of a container. The top aperture defines an aperture peripheral edge, the aperture peripheral edge including two substantially opposed substantially longitudinal segments. The tarpaulin is configurable between an extended configuration and a retracted configuration. In the extended configuration, the tarpaulin substantially covers the top aperture. In the retracted configuration, the tarpaulin is substantially retracted from the top aperture. The device includes an elongated guiding component defining a guiding component longitudinal axis. The guiding component is securable to the container so as to extend at least partially along at least one of the longitudinal segments. A tarpaulin mounting component is usable for attaching the tarpaulin thereto. A link, mechanically coupled to the guiding component, is longitudinally movable therealong between a link proximal position and a link distal position. The tarpaulin mounting component is operatively coupled to the link in a manner such that when the link is in the link proximal position, and the tarpaulin is attached to the tarpaulin mounting component, the tarpaulin is in the retracted configuration. When the link is in the link distal position and the tarpaulin is attached to the tarpaulin mounting component, the tarpaulin is in the extended configuration.

Heated Graphite Scrubber to Reduce Interferences in Ozone Monitors
ActiveUS20160025696A1Good choiceMinimize releaseDispersed particle separationScattering properties measurementsMeasurement deviceAtmospheric air
The present invention provides a means of greatly reducing interferences from mercury vapor, UV-absorbing compounds and water vapor in the measurement of ozone by UV absorbance. A heated graphite scrubber destroys greater than 99% of ozone passing through it while reducing biases from typical atmospheric UV-absorbing interferents by large factors compared to conventional ozone scrubbers. Substitution of a heated graphite scrubber in place of traditional ozone scrubbers such as hopcalite, metal oxides and heated silver scrubbers, results in a more accurate measurement of ozone by reducing the responses to UV-absorbing interferences and water vapor. The heated graphite scrubber also may be used in combination with other ozone sensors, such as electrochemical and HMOS sensors, to provide a reference measurement with ozone selectively removed and thus greatly reduce contributions from interfering species in those measurement devices as well.
